<div>Qu&#8217;est-ce que c&#8217;est que cette horreur de virus ?<br />
&quot;Les organes internes commencent à lâcher un par un. Le foie et la rate sont explosés par la charge virale et sont durs au toucher, saturés de cristaux viraux. La moindre piqûre sur la peau (par exemple pour une injection) est extraordinairement douloureuse et peut occasionner des saignements inextinguibles. Certaines muqueuses commencent à se liquéfier, par exemple dans la bouche ou encore dans l&#8217;intestin qui peut être alors détaché et expulsé en morceaux lors de diarrhées. La tableau clinique est celui de multiples hémorragies massives, toutes potentiellement fatales, associées ou causant de multiples nécroses internes et externes.&quot;<br />(<a href="http://dotmana.com/shaarli/?GUTfsA">Permalink</a>)</div>

title: microSD card reflow: quick and dirty PCB with Kicad
uri: microSD-card-reflow-quick-and-dirty-PCB-with-Kicad
url: http://www.dotmana.com/weblog/2015/08/microsd-card-reflow-quick-and-dirty-pcb-with-kicad/
content:
<p>Ever wanted to add a lot a flash memory to a small microcontroller? NOR flash or EEPROM are ok, but only for small size. For Gbit range, you need NAND, and with NAND comes CCR, LUT, wearleveling, etc&#8230; Furthermore, they are darn expensive in small volume.</p>
<p>SD and microSD card are very interesting: they cost nothing, and you just need a SPI interface as the controller is included.</p>
<p>Last night, I thought: &#8220;why not reflow a complete microSD card&#8221;, and save the cost of the socket, and PCB footprint size. As the card is composed of the same resin as chip casing and pins are flat bellow the microSD card and even gold plated, fore sure it should not be a problem to bring this to 270°C for 2-3 min&#8230;.</p>
<p><strong>Let&#8217;s try!</strong></p>
<p><a href="http://www.dotmana.com/weblog/wp-content/uploads/micro-sd-card.jpg"><img class="aligncenter size-medium wp-image-2074" title="micro-sd-card" src="http://www.dotmana.com/weblog/wp-content/uploads/micro-sd-card-300x200.jpg" alt="" width="300" height="200" /></a>Here is the pinout</p>
<p><a href="http://www.dotmana.com/weblog/wp-content/uploads/izQKT.png"><img class="aligncenter size-medium wp-image-2075" title="izQKT" src="http://www.dotmana.com/weblog/wp-content/uploads/izQKT-300x170.png" alt="" width="300" height="170" /></a>Then let&#8217;s create a small board, to try the reflow of a micro SD card and give access with some 2.54mm header.</p>
<p>Lets open Kicad and start with the schematic with Eeschema:</p>
<p><a href="http://www.dotmana.com/weblog/wp-content/uploads/Screenshot-from-2015-03-12-164305.png"><img class="aligncenter size-medium wp-image-2076" title="Screenshot from 2015-03-12 16:43:05" src="http://www.dotmana.com/weblog/wp-content/uploads/Screenshot-from-2015-03-12-164305-300x228.png" alt="" width="300" height="228" /></a></p>
<p>Then PCB new for the board layout:</p>
<p><a href="http://www.dotmana.com/weblog/wp-content/uploads/Screenshot-from-2015-03-12-163930.png"><img class="aligncenter size-medium wp-image-2077" title="Screenshot from 2015-03-12 16:39:30" src="http://www.dotmana.com/weblog/wp-content/uploads/Screenshot-from-2015-03-12-163930-300x236.png" alt="" width="300" height="236" /></a>Let&#8217;s submit the gerber files to <a href="https://oshpark.com" target="_blank">OSH Park</a></p>
<p><a href="http://www.dotmana.com/weblog/wp-content/uploads/thumb_i.png"><img class="aligncenter size-full wp-image-2078" title="thumb_i" src="http://www.dotmana.com/weblog/wp-content/uploads/thumb_i.png" alt="" width="200" height="161" /></a>Total including USPS post mail: 4.10€</p>
<p>That was my fastest board made ever, 1h30 from searching the pinout to the confirmation email!</p>
<p>See you back in few week for the oven reflow test!</p>
<p>Update: the board and the reflow!</p>
<p><a href="http://www.dotmana.com/weblog/wp-content/uploads/IMG_20150814_084727.jpg"><img class="aligncenter size-medium wp-image-2118" title="IMG_20150814_084727" src="http://www.dotmana.com/weblog/wp-content/uploads/IMG_20150814_084727-300x224.jpg" alt="" width="300" height="224" /></a>First, let&#8217;s clean it and apply some flux:</p>
<p><a href="http://www.dotmana.com/weblog/wp-content/uploads/IMG_20150814_084757.jpg"><img class="aligncenter size-medium wp-image-2117" title="IMG_20150814_084757" src="http://www.dotmana.com/weblog/wp-content/uploads/IMG_20150814_084757-300x224.jpg" alt="" width="300" height="224" /></a>Then some solder on the pads, and flux again:</p>
<p><a href="http://www.dotmana.com/weblog/wp-content/uploads/IMG_20150814_084950.jpg"><img class="aligncenter size-medium wp-image-2116" title="IMG_20150814_084950" src="http://www.dotmana.com/weblog/wp-content/uploads/IMG_20150814_084950-300x224.jpg" alt="" width="300" height="224" /></a>Time to turn the heating plate and IR reflow on:</p>
<p><a href="http://www.dotmana.com/weblog/wp-content/uploads/IMG_20150814_085032.jpg"><img class="aligncenter size-medium wp-image-2121" title="IMG_20150814_085032" src="http://www.dotmana.com/weblog/wp-content/uploads/IMG_20150814_085032-300x224.jpg" alt="" width="300" height="224" /></a>Just stir it a bit while it&#8217;s hot:</p>
<p><a href="http://www.dotmana.com/weblog/wp-content/uploads/ezgif-1282795011.gif"><img class="aligncenter size-full wp-image-2123" title="ezgif-1282795011" src="http://www.dotmana.com/weblog/wp-content/uploads/ezgif-1282795011.gif" alt="" width="480" height="360" /></a></p>
<p>Houston, we have a reflow!</p>
<p><a href="http://www.dotmana.com/weblog/wp-content/uploads/IMG_20150814_0854421.jpg"><img class="aligncenter size-medium wp-image-2120" title="IMG_20150814_085442" src="http://www.dotmana.com/weblog/wp-content/uploads/IMG_20150814_0854421-300x224.jpg" alt="" width="300" height="224" /></a></p>
<p>Then time to test: lets scavenge a super cheap reader microSD card reader:</p>
<p><a href="http://www.dotmana.com/weblog/wp-content/uploads/IMG_20150814_153453.jpg"><img class="aligncenter size-medium wp-image-2128" title="IMG_20150814_153453" src="http://www.dotmana.com/weblog/wp-content/uploads/IMG_20150814_153453-300x224.jpg" alt="" width="300" height="224" /></a></p>
<p>And plug it: IT WORKS! After 3 min under the IR station, it does work.</p>
<p>I think I&#8217;ve to increase the pad size, in order to maximize the solder paste.</p>
<p>Now I&#8217;m confident sending to production, as I&#8217;ve quite a lot of theses cards in trays, ready for pick and place:<a href="http://www.dotmana.com/weblog/wp-content/uploads/IMG_20150814_093337.jpg"><img class="aligncenter size-medium wp-image-2119" title="IMG_20150814_093337" src="http://www.dotmana.com/weblog/wp-content/uploads/IMG_20150814_093337-300x224.jpg" alt="" width="300" height="224" /></a></p>

<div>Analyse très intéressante&#8230;<br />
&quot;L’Eglise a les pires peines du monde à lutter contre le jeu et n’y parvient que lorsque le protestantisme se développe au XVIe siècle. A la faveur de ce schisme, brusquement, les masques et les tréteaux disparaissent des parvis. Les chants lubriques et à boire des goliards sont proscrits. Fini de rire. Fini de jouer. Seuls les enfants ont encore le droit de jouer, et encore. Jouer devient la marque d’une nature frivole, immature, vicieuse. Un adulte ne saurait sans déchoir jouer comme une petite fille à faire «comme si» il était quelqu’un d’autre. On le soupçonne d’être pervers, morbide ou déviant.&quot;<br />(<a href="http://dotmana.com/shaarli/?9i8p7w">Permalink</a>)</div>

<div>&quot;A toutes les étapes de la production et de l’élaboration, le produit doit répondre à des critères minimaux et à des exigences minimales de contrôle qui peuvent être précisées dans des notices techniques, réactualisées périodiquement.&quot;<br />
-&gt; exigences minimales : ça nous fait une belle jambe et ça signifie que les autres produits non labelisés n&#8217;ont aucune exigence minimale&#8230;</p>
<p>&quot;Des tests organoleptiques doivent obligatoirement être réalisés afin de démontrer la qualité gustative du produit candidat au Label.&quot;<br />
-&gt; belle couleur, ça sent bon, c&#8217;est juteux : c&#8217;est parfait, vous pouvez consommer !</p>
<p>&quot;Toute demande tendant à la reconnaissance d’un Label rouge par homologation d’un cahier des charges est déposée, par un groupement de producteurs ou de transformateurs auquel a été reconnue la qualité d’organisme de défense et de gestion, auprès de l’Institut national de l’origine et de la qualité (INAO).&quot;</p>
<p>-&gt; donc on demande au producteur de se créer son propre cahier des charges qu&#8217;il s&#8217;engage à respecter. Whoua ! Ça doit être ultra contraignant, aucun doute !</p>
<p>On peut notamment regretter que cette labelisation n&#8217;intègre aucun paramètre sur les pesticides. Même si la BIO n&#8217;est pas parfaite, voici un comparatif éclairant : <br />

<p>Rationale: compensate a speaker response curve (gain and phase) on a audio file.</p>
<p>Just came accross <a href="http://www.roomeqwizard.com/" target="_blank">REW (Room EQ Wizard)</a> (Linux, Windows, Mac), it let you plot the output of your speakers, then create a filter to compensate the flaws.</p>
<p>Once you created your finely tuned speakers, Export-&gt; Filter as text file.</p>
<p>Then, it&#8217;s time to process the audio file with this filter, using the amazing Sox:</p>
<p>sox -q input_file.wav output_file.wav `awk &#8216;$4==&#8221;PK&#8221; { gsub(/,/,&#8221;",$6 );val=$6;printf &#8221; equalizer &#8220;val&#8221; &#8220;$12&#8243;q &#8220;$9}&#8217; val=&#8221;%&#8217;6.3f&#8221; REW_filter.txt`</p>
<p>That&#8217;s it: you have a outputfile with the correct compensation for your just analysed speaker.</p>
<p>Of course this method is for non-real time need.</p>

&quot;Afin d’exclure les versions des navigateurs ne répondant pas aux normes de sécurité récentes, la Douane va relever à partir du 1er juillet 2015 les versions minimales des navigateurs supportés par le site Prodouane et les téléprocédures. Par ailleurs, les navigateurs peu utilisés sur le site Prodouane, comme Safari (moins de 2% d’accès), sortiront également de ce palier. Ainsi, à compter du 1er juillet 2015, les versions de navigateurs supportées seront : Internet Explorer 8.0 et suivants Firefox 17 et suivants. Les utilisateurs sous Mac OS sont invités à télécharger de préférence le navigateur Firefox.&quot;</p>

<p>Ever wanted to have nice plot (U/I curve, whatever) simply plotted?</p>
<p>I got 2 UNI-T UT61E with USB cable (50€ each)</p>
<p><a href="http://www.dotmana.com/weblog/wp-content/uploads/UT61E.png"><img class="aligncenter size-medium wp-image-2161" title="UT61E" src="http://www.dotmana.com/weblog/wp-content/uploads/UT61E-146x300.png" alt="" width="146" height="300" /></a><a href="http://www.dotmana.com/weblog/wp-content/uploads/411ybx5DFlL._SY355_.jpg"><img class="aligncenter  wp-image-2160" title="411ybx5DFlL._SY355_" src="http://www.dotmana.com/weblog/wp-content/uploads/411ybx5DFlL._SY355_-300x300.jpg" alt="" width="129" height="129" /></a></p>
<p>With <a href="http://sigrok.org/" target="_blank">sigrok</a> you can easily get data from many device with a single command:</p>
<blockquote><p>sigrok-cli &#8211;driver=uni-t-ut61e:conn=BUS.DEVICE -O analog  &#8211;continuous</p></blockquote>
<p>Where BUS and DEVICE is replaced with the output of lsusb</p>
<blockquote><p>lsusb<br />
Bus 002 Device 002: ID 8087:8001 Intel Corp.<br />
Bus 003 Device 086: ID 1a86:e008 QinHeng Electronics HID-based serial adapater<br />
Bus 003 Device 087: ID 1a86:e008 QinHeng Electronics HID-based serial adapater</p></blockquote>
<p>In my case, as I&#8217;ve 2 devices, so 2 different commands are used:</p>
<blockquote><p>sigrok-cli &#8211;driver=uni-t-ut61e:conn=3.86 -O analog  &#8211;continuous</p>
<p>sigrok-cli &#8211;driver=uni-t-ut61e:conn=3.87 -O analog  &#8211;continuous</p>
<p>&nbsp;</p></blockquote>
<p>But what about logging in <strong>the</strong> <strong>same file </strong>the two ouputs simultaneously?</p>
<p>Here comes the magical function: paste and joined pipe:</p>
<blockquote><p>paste &lt;(sigrok-cli &#8211;driver=uni-t-ut61e:conn=3.86 -O analog  &#8211;continuous) &lt;(sigrok-cli &#8211;driver=uni-t-ut61e:conn=3.87 -O analog  &#8211;continuous) &gt; measure.csv</p>
<p>&nbsp;</p></blockquote>
<p>I&#8217;ll let you deal with the uber simple csv processing with octave or libreoffice calc (mV, mA range condition, etc&#8230;), as this blog entry is mainly used as a personal notepad.</p>
<p>&nbsp;</p>
<p>Note: if you have trouble connected with sigrok, with an error. You may need to disable the power feature, with the script pointed by <a href="http://blog.philippklaus.de/2014/05/true-rms-digital-multimeter-uni-t-ut61e/" target="_blank">blog.philippklaus.de</a></p>

&#8212;&#8212;&#8212;<br />
After getting the DSM 6.0 upgrade, I’ve become unable to login as root using SSH, even though I’ve been able to do it before the upgrade (DSM 5.5 or something like that).<br />
The solution:<br />
1. SSH to machine as admin user.<br />
2. Enter command “sudo su” and providing admin password.<br />
3. Enter command “synouser -–setpw root “.<br />
Now I’m able to logon as root using SSH again, and I didn’t have to mess with telnet.<br />(<a href="http://dotmana.com/shaarli/?-_YZvw">Permalink</a>)</div>

<div>Un condamné à mort dont on s&#8217;occupe mieux, ça exonère du fait de le tuer à la fin ?</p>
<p>&quot;les animaux bénéficient d’un espace de 1,5 m² par tête (contre 0,7 m² en conventionnel)&quot; : youhou ! incroyable ! mais dans tous les cas on te mange hein !</p>
<p>&quot;Aussi, j’attends 5 à 6 chaleurs avant d’inséminer une truie. De cette façon, elle est plus développée et plus résistante aux maladies. La mise bas se passe mieux, sans avoir besoin d’hormones. Plus la mise bas est courte, plus la truie se remet bien. Et les petits sont en meilleure santé.&quot; : moi aussi, je fais mes vidanges régulièrement et j&#8217;évite de faire tourner le moteur à plein régime si il est froid. Putain, on parle d&#8217;un être vivant et sentient comme si c&#8217;était de la mécanique&#8230;</p>
<p>&quot;La phase d’engraissement terminée, les cochons sont mis à mort dans le petit abattoir de Quintin&quot; : c&#8217;est mignon, ça donnerait presque envie de se faire bouffer.</p>

+1 Merci pour ce rappel évident, mais qui change du &quot;un bon coup de pied au cul&quot; ou &quot;une bonne baffe&quot; (comme si les 2 gestes pouvaient être &quot;bons&quot;).</p>
<p>&quot;Déjà, prendre soin de nos gamins. &nbsp;C’est con, je sais, mais en fait la plupart des connards qu’on croise et qui nous font chier aujourd’hui ont eux-même été élevés par des connards. &nbsp;Ou abandonnés par des connards et élevés par d’autres.&quot;<br />
+2 L&#8217;adulte d&#8217;aujourd&#8217;hui était l&#8217;enfant d&#8217;hier et réciproquement.</p>
<p>&quot;Bref, les gamins ont besoin d’amour, de cohérence, de cadre bienveillant, et de limites posées clairement et régulièrement. &nbsp;Et non, une baffe n’est pas qu’une limite. &nbsp;Une baffe est une limite qui fait mal et qui fout la haine de soi-même et des autres. &nbsp;Les enfants ont besoin de comprendre pourquoi on ne peut pas cogner sur qui on veut ou jeter ses poubelles n’importe où… &nbsp;Ils ont besoin de la certitude que nous serons toujours bienveillant avec eux : pas complaisants, pas maltraitants. &nbsp;Bienveillants. &quot;<br />

<div>Paye ton échec Linky sur toute la ligne. L&#8217;effacement de consommation ne sert à (presque rien), tu te fais moucharder sur ta conso privée et tout ça pour quoi au fait ? Ah oui, d&#8217;après l&#8217;article : <br />
&quot;Avec ses suivis de consommation en quasi-temps réel, Linky permet d’ajuster en permanence l’achat<br />
et la vente d’électricité sur le marché de gros (European Power Exchange). Voilà sa véritable utilité.&quot;</p>
<p>&#8212;&#8212;&#8211;<br />
Il a lu une récente étude de RTE (Réseau de transport d’électricité) qu’il résume ainsi : « Le grand risque, avec Linky, c’est qu’on n’arrive pas à faire beaucoup mieux que les compteurs &quot;heures creuses/heures pleines&quot; avant pas mal d’années ». Bref, « les gains économiques ne sont pas très élevés », euphémise-t-il.<br />
Linky n’a aucun intérêt pour le consommateur. La preuve en est fournie par l’expérimentation GreenLys justement. Durant quatre ans, ERDF et ses partenaires ont testé les « effacements » (baisse de fourniture à distance) sur des cobayes volontaires. Ils ont diminué le chauffage de 1° chez ceux-ci pendant une heure ou un quart d’heure, plusieurs fois par jour. Résultat : « Au moment du retour à la consigne de l’habitant, les radiateurs tournent à plein régime pour compenser la différence de température. L’appel de puissance du logement est alors 50 % plus élevé par rapport à un jour sans effacement. Ces mêmes radiateurs consomment aussi 40 à 60 % d’énergie supplémentaires dans les minutes qui suivent le changement d’instruction. Au total, ils utilisent autour de 95 % de l’énergie effacée dans les 24 heures après la fin de la procédure. » Ceci n’est pas un film des Monty Python, mais l’œuvre de nos ingénieurs.<br />(<a href="http://dotmana.com/shaarli/?wO4ChQ">Permalink</a>)</div>

<p>&quot;Teach your children that the prophets have condemned it as a sin throughout the ages and that they can choose not to do it.&quot;</p>
<p>&quot;The sin of masturbation occurs when a person stimulates his or her own sex organs for the purpose of sexual arousal. It is a perversion of the body’s passions. When we pervert these passions and intentionally use them for selfish, immoral purposes, we become carnal.&quot;</p>
<p>&quot;Your teenagers will also be tempted to have sexual relations with others before they are married.&quot;<br />(<a href="http://dotmana.com/shaarli/?xPuyXg">Permalink</a>)</div>

<p>Here is a very simple fume extractor fan, to put an halt to apnea soldering.<a href="http://www.dotmana.com/weblog/wp-content/uploads/P61108-142244.jpg"><img class="size-large wp-image-2208 aligncenter" title="P61108-142244" src="http://www.dotmana.com/weblog/wp-content/uploads/P61108-142244-1024x758.jpg" alt="" width="584" height="432" srcset="http://www.dotmana.com/weblog/wp-content/uploads/P61108-142244-1024x758.jpg 1024w, http://www.dotmana.com/weblog/wp-content/uploads/P61108-142244-300x222.jpg 300w, http://www.dotmana.com/weblog/wp-content/uploads/P61108-142244-405x300.jpg 405w" sizes="(max-width: 584px) 100vw, 584px" /></a></p>
<p><strong>Made of:</strong></p>
<ul>
<li>DC/DC buck boost converter (3€ on ebay)</li>
<li>USB battery pack 5€</li>
<li>scrapped fan</li>
<li>scrapped switch</li>
<li>scrapped potentiometer</li>
<li>Hammond prototype case (1€, same as my <a href="http://www.dotmana.com/weblog/2014/06/usb-motion-sensor-pir-to-wake-up-screen/">USB motion sensor</a>)</li>
<li>nice labels</li>
<li>double side tape</li>
</ul>
<p>Enough talk, a picture:</p>
<p><a href="http://www.dotmana.com/weblog/wp-content/uploads/P61108-142232.jpg"><img class="size-large wp-image-2207 alignnone" title="P61108-142232" src="http://www.dotmana.com/weblog/wp-content/uploads/P61108-142232-1024x758.jpg" alt="" width="584" height="432" srcset="http://www.dotmana.com/weblog/wp-content/uploads/P61108-142232-1024x758.jpg 1024w, http://www.dotmana.com/weblog/wp-content/uploads/P61108-142232-300x222.jpg 300w, http://www.dotmana.com/weblog/wp-content/uploads/P61108-142232-405x300.jpg 405w" sizes="(max-width: 584px) 100vw, 584px" /></a></p>
<p>And in action, can suck up to 15cm at medium speed:</p>
<p><a href="http://www.dotmana.com/weblog/wp-content/uploads/P61108-142018.gif"><img class="size-full wp-image-2206 aligncenter" title="P61108-142018" src="http://www.dotmana.com/weblog/wp-content/uploads/P61108-142018.gif" alt="" width="320" height="320" srcset="http://www.dotmana.com/weblog/wp-content/uploads/P61108-142018.gif 320w, http://www.dotmana.com/weblog/wp-content/uploads/P61108-142018-150x150.gif 150w, http://www.dotmana.com/weblog/wp-content/uploads/P61108-142018-300x300.gif 300w" sizes="(max-width: 320px) 100vw, 320px" /></a></p>
<p>This &#8220;hack&#8221; took me 30min, and costs close to nothing, while some have been <a href="http://jumperone.com/2011/07/portable-fume-extractor/">down to build a DC/DC converter for this!</a></p>
<p>Thing to add in the future:</p>
<ul>
<li>active carbon filter for better filtering, but usable as is for small jobs: you don’t get fumes in your face anymore.</li>
<li>USB light for soldering in the dark</li>
</ul>
<p>My favourite use: in the freezer/fridge, when you forgot to chill beers for an unexpeted party, it takes only 10min to have freezing beer instead of 1h. (remove the carbon filter first&#8230;)</p>

<p>4 years after the previous article, I still need this tool, but I wanted a more &#8220;natural&#8221; TTS.</p>
<p>So I&#8217;m using <a href="https://www.voxygen.fr/">Voxygen</a>, a natural TTS provider (very good for French), retrieving the generated voice with wget and the following command:</p>
<pre>wget --quiet --no-check-certificate -O /tmp/clock_`date +\%-1H`.mp3 "https://www.voxygen.fr/sites/all/modules/voxygen_voices/assets/proxy/index.php?method=redirect&amp;text=il est exactement `date +\%-1H` heures.&amp;voice=Loic"</pre>
<p>Here is the script to run every hours:</p>
<pre>if [ ! -e /tmp/clock_`date +\%-1H`.mp3 ]; then wget --quiet --no-check-certificate -O /tmp/clock_`date +\%-1H`.mp3 "https://www.voxygen.fr/sites/all/modules/voxygen_voices/assets/proxy/index.php?method=redirect&amp;text=il est exactement `date +\%-1H` heures.&amp;voice=Loic"; fi ; mpg321 /tmp/clock_`date +\%-1H`.mp3 --gain 200</pre>
<p>We will be using gnome schedule taks:</p>

<p>They are simply dust, fingerprint and scratch magnet, everything is summarised in the amazing book <strong><span id="productTitle" class="a-size-extra-large">The Hardware Hacker: Adventures in Making and Breaking Hardware </span></strong>from <a href="https://www.bunniestudios.com/">Andrew &#8216;bunnie&#8217; Huang</a></p>

<blockquote><p>&#8220;My world is full of small frustrations like this. For example, most customers perceive plastics with a mirror finish to be of a higher quality than those with a satin finish. There is no functional difference between the two plastics&#8217; structural performance, but making something with a mirror finish takes a lot more effort. The injection-molding tools must be pains-takingly and meticulously polished, and at every step in the factory, workers must wear white gloves. Mountains of plastic are scrapped for hairline defects, and extra films of plastic are placed over mirror surfaces to protect them during shipping. For all that effort, for all that waste, what&#8217;s the first thing users do? They put their dirty fingerprints all over the mirror finish. Within a minute of a product coming out of the box, all that effort is undone. Or worse yet, the user leaves the protective film on, resulting in a net worse cosmetic effect than a satin finish. Contrast this to satin-finished plastic. Satin finishes don&#8217;t require protective films, are easier for workers and users to handle, last longer, and have much better yields. In the user&#8217;s hands, they hide small scratches, fingerprints, and bits of dust. Arguably, the satin finish offers a better long-term customer experience than the mirror finish. But that mirror finish sure does look pretty in photographs and showroom displays!&#8221;</p></blockquote>

<p>We love to listen to <a href="https://www.fip.fr/" target="_blank" rel="noopener">FIP</a>, as it&#8217;s a public radio, without commercials and not so much speaking.<br />
Unfortunately, this radio is FM brodcasted in only few city in France, and here in Grenoble, the only way to get is internet.</p>
<p>So we built this small kitchen radio, music playing in 14 seconds, and quite pleasantly aesthetic, in the same line as my previous <a href="http://www.dotmana.com/weblog/2015/02/simple-cnc-desktop-router-workflow-and-example/">nixie clock.</a></p>
<p>The large solid aluminium knob with amplifier pot ON/OFF produces a comforting click to power ON/OFF the device or adjust the volume.<br />
The shiny stainless steel button is for future upgrade to allow changing from few radio as currently only one is available.</p>
<h1>Hardware part</h1>
<p>Here are almost all the items needed for this DIY hack:</p>

<p>Here is a small DIY project, for a portable/bench-top power supply. We are not aiming for the best regulation, neither most power. But portability and bench-top estate optimisation.</p>
<p>This is based on the famous <a href="https://www.google.fr/search?q=DPS3005+power+supply">DPS3005 (about 25€)</a></p>

uri: Dual-Sim-micro-SD-Hack
url: http://www.dotmana.com/weblog/2019/08/dual-sim-micro-sd-hack/
content:
<p>Dual SIM smartphones are now common.</p>



<p>But most of them due to the card tray design, can either accept:</p>



<ul><li>two SIM but no micro-SD</li><li>one SIM and a micro-SD card</li></ul>



<p>This is definitely a bugger since mid-range Android smartphones are pretty  stingy with storage memory (from 16Gb to 32Gb), while micro SD are pretty cheap an wayyyyy larger (128Gb to 512Gb)</p>



<p>Here is the quick hack to insert both dual sim, and a micro SD.</p>



<p>Tools needed</p>

<p>Peel the back of the nano-SIM plastic, with a hot air gun, as it&#8217;s soften the back glue, heat gently and evenly the back, to not fry the sim. (you may want to try first with a discarded SIM card, sitting in your junk-box)</p>

<p>Clip about 1mm the sides of the FR4 epoxy SIM card</p>

<p>File the edge on the micro SD card, so it&#8217;s thinner, and don&#8217;t have this edge protruding anymore and shaves few microns of the card.</p>



<p>It&#8217;s interesting the flipchip design, reflown or wire bonded on a thin PCB with the finger contacts, then overmolded with the final plastic case. 400Gb are store in this die, that&#8217;s awesome, I guess, the controller must be integrated too, not separated as in Bunnie&#8217;s entry: <a href="https://www.bunniestudios.com/blog/?page_id=1022">https://www.bunniestudios.com/blog/?page_id=1022</a></p>



<p>I don&#8217;t know if one can reflow this design as experimented here: <a href="http://www.dotmana.com/weblog/2015/08/microsd-card-reflow-quick-and-dirty-pcb-with-kicad/">http://www.dotmana.com/weblog/2015/08/microsd-card-reflow-quick-and-dirty-pcb-with-kicad/</a></p>

<p>Tape the other side with the shrinked second SIM</p>



<p> (take extra care where the chip should align, here I made scratches with the scalpel with the unmodified nano sim where it should go)</p>



<p>Here I used Kapton tape, but I guess any office tape would do</p>

<p>Well defined product functionality implemented with mature and state of the art industrial process can yield very nice products.</p>



<p>But in some cases, pushing sleekness over function don&#8217;t deserve the product well. This is especially the case for prosumer product: professional consumer want sturdy, rugged product, surviving the field.</p>



<p>Even a sales person on a show with a tablet for demo want certain level of toughness: the tablet can be drop by the visitor, will be abused during storage and transport, etc..</p>



<p>Today I want to talk about SumUp Air: a small payment terminal, synced with your smartphone to accept payment over 3G/4G or Wifi.</p>



<p>The idea is great: use your smartphone to do the accounting/sales stuff, while having a dedicated card reader with pin input Bluetooth synced to hand to the customer.</p>



<p>But the implementation is very, very poor.</p>



<p>After few years of use, I found out the following issues:</p>



<ul><li>the device is BLE: it&#8217;s always on, advertising every 10sec: this sucks as if you have it in your car with your stock, it is a plain beacon and screaming to be broken in</li><li>the device cannot be switch off: yes, there is no way to switch it off. Contacting the support service, they told me you cannot even remove the battery as the signature/encryption key are in volatile memory (this is interesting as the battery must definitely be a li-po and can be over-discharged at some point)</li><li>the keyboard interface is tactile (capacitive sensors), customer have trouble typing the pin in as there is no feedback of the switch press: why using a tactile technology for this!</li><li>the front face is glass: just drop it and it will shatter: this is a field tool, the device WILL fall down, especially while handling it to customers, outdoors, etc..</li><li>Bluetooth wake up and pairing is just a pain: while it&#8217;s supposed to wake up when you start the transaction on your smartphone, most of the time it doesn&#8217;t: you can to re-enable discovery/pairing on the front of you customer</li><li>Location must be enabled on your smartphone: while this is interesting for transaction history, this is also a bad idea: it just drains the battery from your smartphone super fast.</li></ul>

<p>TS100 is a very good iron solder, with a rated power of 17 to 65W, when powered from 12 to 24V.</p>



<p>While 12V DC jack DC5525 are everywhere, 24V are less but needed if you want more heat to solder larger components or grounds. (better than the TS-80 with the weak 18W anyway)</p>



<p>Supplying from USB-C source with PD 19V 60W takes full advantage of this iron solder.</p>

<p>I&#8217;ve stumble upon a fairly common appliance, present in most home, built by million of unit, a TV.</p>



<p>This model is a GRUNDIG 40VLE5324BG with LED backlight: not starting anymore (one could see the &#8220;Grunding&#8221; logo or &#8220;signal not present&#8221; when flashing a strong light on it).</p>



<p>After seeking the net for a solution, removing dozen of screws, accessing the 100cm long LCD panel made of ultra thin glass with COG and flex PCB on side, I finally had access to the culprit: No, it was not the capacitor, not the LED driver, not even a LED but a single connector: PCB to PCB connector, designed to decrease assembly time and cost. As these LED string are serial driven (140V @ 400mA), a single failure will render the whole system useless. </p>



<figure class="wp-block-image"><a href="http://www.dotmana.com/weblog/wp-content/uploads/40VLE5324BG_led_failure.png"><img src="http://www.dotmana.com/weblog/wp-content/uploads/40VLE5324BG_led_failure-1024x782.png" alt="" class="wp-image-2412" srcset="http://www.dotmana.com/weblog/wp-content/uploads/40VLE5324BG_led_failure-1024x782.png 1024w, http://www.dotmana.com/weblog/wp-content/uploads/40VLE5324BG_led_failure-300x229.png 300w, http://www.dotmana.com/weblog/wp-content/uploads/40VLE5324BG_led_failure-768x586.png 768w, http://www.dotmana.com/weblog/wp-content/uploads/40VLE5324BG_led_failure-393x300.png 393w, http://www.dotmana.com/weblog/wp-content/uploads/40VLE5324BG_led_failure.png 1365w" sizes="(max-width: 1024px) 100vw, 1024px" /></a></figure>



<p>Just wiggling the connector would start/stop the backlight:</p>

<p>In this case, slight flex, oxidation or poor connector plating cause the problem, and as the LED as serial connected, the connector is oxidized from long arcing:</p>

<p>And the connector:</p>

<p>Let&#8217;s strap these connector with a piece of wire and fix this stuff!</p>

<p>We all experienced it: light flicker! When concentrating on a piece of work or dead tree text, the light suddenly goes berserk and flash like a stroboscope on the dance-floor.</p>



<p>After fixing a <a href="http://www.dotmana.com/weblog/2020/04/industrial-manufacturing-dfm-or-planned-obsolescence/">TV with LED backlight</a>, let&#8217;s dive in different performance of light fixture/light bulbs.</p>



<p>This effect is especially present in LED light fixtures where there is no inertia: incandescent or fluorescent light have a thermal or phosphor inertia and continue to glow a flick of second after the power is cut. But not the LED (even though there is some phosphor in them), this leads to have a close relation of the light intensity and the supply voltage.</p>



<p>Most of LED light bulb are supplied from main, the quality of the AC/DC converter takes a main role here. Because good rectification and filtering cost, manufacturer are cutting them, and you get this effect.</p>



<p>You can find two type of power supply on LED bulbs: simple rectification with LED string to match the AC rectified voltage. Or AC/DC converter with inductor and constant current control (this is what you want).</p>



<p>I wanted to &#8220;quantify&#8221; it, more that just a feeling, but didn&#8217;t want to drop hard cash (k€$ range) for dedicated equipment.</p>



<p>So I used one of the simplest and cheaper photo sensor on the market: a NPN phototransistor, (not a photoresistance as the bandwith is to small), in addition with a 10k resistor, connected to the GND (ring 2) and MIC (sleeve).</p>

<p>I now always have this small 3.5mm 4 ring photo-transistor adapter in my pocket when shopping light bulb/appliances in home improvement, so I can point it and discard the worst devices.</p>



<p>If someone comes up with a better idea, to measure more accurately amplitude and ideal the spectrum (would need a dedicated color sensor though), with an easy to use interface, that would be awesome.</p>

<p>Interstellar is an awesome movie, and the sound track is even better.</p>



<p>But after having listened it quite few times the original sound track, I quickly realize there is something wrong, not the <a href="https://en.wikipedia.org/wiki/Loudness_war">loudness war</a>, something worst: noise pickup during recording, not filtered out during mixing.</p>



<figure class="wp-block-image"><img src="http://www.dotmana.com/weblog/wp-content/uploads/image.png" alt="" class="wp-image-2443" srcset="http://www.dotmana.com/weblog/wp-content/uploads/image.png 887w, http://www.dotmana.com/weblog/wp-content/uploads/image-300x121.png 300w, http://www.dotmana.com/weblog/wp-content/uploads/image-768x309.png 768w, http://www.dotmana.com/weblog/wp-content/uploads/image-500x201.png 500w" sizes="(max-width: 887px) 100vw, 887px" /><figcaption>Track 06: Message from Home showing the 15735Hz peak at 51dB </figcaption></figure>



<p>Almost the complete album is tainted, for example, in this track, &#8220;Message from Home&#8221;, is a single piano recording showing this noise standing out clearely.</p>



<p>Dont get me started it&#8217;s because of the MP3 or format artifact, this is present on any version, MP3, FLAC, and even on Spotify online!</p>



<p>Here is an extract of this sound track, do you hear it? It hurts!</p>

<p>If you cannot hear sounds around 16Khz, no problem, here pitched down version, to 0.5 with the noise is now at 8Khz if you don&#8217;t hear it, you may want to consult a specialist.</p>

<p>Because it may sound crazy that a multi million dollar movie, OST and sound track composer (Hans Zimmer) get away with this, I&#8217;ve looked up and found this reddit thread mentioning it:</p>

<p>Well, I&#8217;m not crazy after all and it look like it&#8217;s a <a href="https://en.wikipedia.org/wiki/Pilot_signal">Pilot Signal</a> at &#8220;15.7342657 kHz is used to indicate the presence of <a href="https://en.wikipedia.org/wiki/Multichannel_television_sound">MTS</a> stereo.&#8221;</p>



<p>So that&#8217;s it, there is nothing to do, we are stuck with this (at least I can filter out my own version), but please, mixing engineers, next time, pay attention.</p>

<p>Change the RCS resistor from 50mOhm to 125mOhm (0.125 Ohm) to change the charging current to 300mA.</p>



<p>Remember, these bulb have to be supplied 16V (min) so the filament starts glowing, but once the arc is established, current has to be limited to 300mA (settling at around 10V)</p>
