#kicad — Public Fediverse posts

Kolega przyszedł i mówi, że popsuła się grzałka w termocyklerze (dużo trudnych słów i skrótów w stylu DNA) i jakaś tasiemka nie pamiętam do czego. I że tego ustrojstwa nie da się kupić luzem tylko z czymśtam™ i bardzo drogo no i czy chciałbym spróbować.

No jak nie jak tak!
Trochę pomarudziłem, że to poprzednie wymaga godziny żeby sprawdzić czy wyszło, ale przecież nie mogłem odpuścić zabawy. :D

#DIY #KiCad

While I wait for pcbway to start making my version 3.2 boards, I now have to switch gears from #kicad to #freecad and start designing some of the physical parts of #synthseqr. Ok brain, do a kick flip.

I wrote (another) post about my multi-PCB workflow in @kicad (using @freecad 's Python interface to do 3D transforms in CLI).

My first KiCad PCB(actually on perfboard) :blobcat_mlem:

I finally arranged all components and routed them on perfboard.
Some I put underneath others, cool. Turned out to be more compact than expected.

I hope it is all good, and I will be able to solder it tomorrow.

Btw #KiCad pcb thing is much more comfortable and smart/automatic than schematic. I liked it. Although speicifically perfboard optimized workflow would be convenient.

I designed it as a pcb with 2.54mm grid and many layers, and routing though things, ignoring many rules.
As this wonderful [Arduino forum post suggested](https://forum.arduino.cc/t/perfboard-circuit-design-with-kicad/1283999)

Btw free space to the left is left for debug probe. IDK if to port airfrog to pico 2w(I have it) or other esp32. (esp32-c3 super mini I bought, wifi did not work, even with antenna mod)

Now is eepy time.

Now have a fully standalone working #FujiNet prototype for #MSX! No cables running to another computer. Boots right up and goes into config. #3DPrinted #KiCad #Fusion360 #RaspberryPiPico #TRS80CoCo #RetroComputing #VintageComputing #Electronics

Del esquema al PCB 🚀🔔

Después de varias etapas de diseño y pruebas, llegó el momento de fabricar el primer prototipo del PCB para el proyecto del Timbre Escolar Inteligente.

En este video se puede ver parte del proceso: diseño, preparación y fabricación de la placa que va a integrar el ESP8266, control de relés y periféricos del sistema.

Todavía queda bastante trabajo por delante, pero ver cómo el proyecto empieza a tomar forma física es una de las partes más interesantes del desarrollo ⚡

That took quite a lot of battling but I got the new #FujiNet proto board to come up on CoCo! I jumpered the pins for now to make it so all the GPIOs are in the lower 32bit window to make it easier to start from the PicoROM code.

There's now a CoCo version of the case. I added some extra standoffs so the case can be used as a jig while soldering the two boards together. #3DPrinted #KiCad #Fusion360 #MSX #RaspberryPiPico #TRS80CoCo #FujiNet #RetroComputing #VintageComputing #Electronics

I think I've finally finished the boards for the keytar. Unfortunately, I don't know of a convenient PCB manufacturer in the US that offers assembly. I can solder most of them myself, but the board containing 576 LEDs might be a job for a pick-n-place machine. 😅

I'm considering going through @aislerhq to have them made. Has anyone in the states tried them before? Guess I'm worried what the customs situation might look like. 😬 :boost_request:

More keytar updates soon!

#aisler #kicad #pcb #diy #midi #keytar

I designed another PCB... Small preview without revealing what it will be. It'll arrive mid January, though.
They will be manufactured by @aislerhq again, using the 20% December discount for using their #KiCad plugin.
It'll have the option to use an AVR DA compatible #microcontroller or a #tinyAVR one - I added options for both that I have in stock (AVR32DA32 and ATtiny814). Since it won't use many pins, I could have used smaller variants, too.
#AVR #AVRDA #ATtiny #pcbdesign #kicad #aisler #pcbdesign

I wanted to try out a few new things. So, I designed a development board for the AVR DA #microcontroller, the 32 pin #TQFP looked like something I'd be able to hand solder. I really like #UPDI from the ATtiny814. This is the result, my first four layer boards, first time with logos and an image. The image of #Frieren was a bit too small, though. Manufactured by @aislerhq again.

Since the #powersupply for my #IBM #ThinkPad 755C doesn't work reliably and uses a very strange connector, I unsoldered the socket from the internal board. It came on a handy mini #PCB, which I reengineered in @kicad for a barrel jack. It also has connections for a 20V USB-C PD trigger board that I had lying around.
The boards were manufactured by @aislerhq and fit perfectly. Only the barrel jack was a bit tight since I had to smallen the holes a bit to place it on the board.
Now I just have to decide which to solder back into the #laptop. Will have to try which fits better inside the hole.

I designed a #SMD adapter board using @kicad and let @aislerhq manufacture them. They are for #SOT23 on one side and #SOT363 on the other side. They bridge the gap of a #solderless #breadboard, so they are perfect for #prototyping circuits or trying out new components - or as replacement for through-hole parts. I soldered a dual diode #BAV70 on one and a dual NPN/PNP transistor #BC847BPN on a second one to try them out. I'm satisfied how they look, although the white area for labeling is a bit small - I need a thinner pen for that.
You can find the shared project here: https://aisler.net/p/UTAGNLYX (trying out this feature, please give feedback if you use it).

I had this old TBA800 IC lying around. So, I designed an audio amplifier circuit. It was fun to solded and works fine. It should support 5W at 16 Ohms load and 24V supply. I only tested it with 12V and 4 Ohms speaker.
The hardest part was soldering the tabs, since they act as heat sink, too.
I used #KiCad for the schematics and layout, although I had to create my own symbol and footprint for the IC. Also had to cut holes for the tabs into the #perfboard.

Hauerha, ich designe gerade zum ersten mal eine SMD-Platine und bereite sie auch für pick-and-place vor, so dass die Platine auch gleich ab Werk bestückt wird. Das ist ein lustiges Durcheinander von verschiedenen Größen und Typen, da muss man erstmal den Baum vor lauter Wald finden..

Aber #KiCAD und #Aisler s Integration hilft da sehr, seit ich KiCAD zum letzten mal vor 5 Jahren benutzt habe hat sich die Software immens weiter entwickelt!

@mixal
Here is the #schematics done in #KiCad, as well as the "PCB" layout used for the #perfboard and the 3D rendering.
I chose 1µF and 100nF for the caps, smaller being the faster one.
It was inspired heavily by the design of SoundBender found here: https://soundbender36.wordpress.com/2019/12/28/36-synthetiseur-modulaire-diy-dual-lfo/
#diysynth

oh no! how could this happen... I made a mistake when transferring my hand-drawn #schematics into #KiCad. Needless to say, the circuit doesn't work as intended.
Thankfully, it only affects a sparsly populated area on the #perfboard and I can fix it by cutting two wires and doing a bit of re-routing. doesn't even require a jumper wire.
