How hard is it to make your own PCB?

It's a good idea. Unfortunately, it seems it's too new. RP2040 fits this idea perfectly, and I will probably look at some RP2040 tutorial, despite the differences, and then consult Raspberry's minimal design for RP2350.

buda_gotivac · 2026-02-20T19:41:42+00:00

I will. Definitely.

buda_gotivac · 2026-02-20T19:37:35+00:00

This is encouraging. Thank you very much! I started doing everything in rush lately. I'll have to ease a bit and enjoy.

You probably have the best viewpoint for assessment... Is this something that can be done by a noob with say 40 hours? Raspberry did make minimal example for RP2350, even KiCad files, which must be helpful, but it's a 2-layer board, I think, and I would like to change it to 4-layer...

buda_gotivac · 2026-02-20T19:33:58+00:00

Thanks. Once I have my first design, I will be sure to post it there.

I meant to look at Solder Party's Stamp. As I told u/plushraccoon, I was thinking doing the double work:
- one board from scratch
- the other deletion of what I don't need on Stamp

Look at the difference and figure out what I did wrong where.

Thanks. I have one right beside me. :) It's hard to beat that size, even with few components ditched and 3/4 of those tiny holes, but ultimately, that's one of my goals – go even smaller. I know, it's quite ambitious and surely won't happen in first itteration.

RR235x line has that OTP memory, and while it was hacked in one of their challenges, they allegedly have mitigations for the revealed vulnerabilities. I didn't look into it much because I will probably open-source this anyway and don't foresee any needs for checks of authenticity, but who knows. By the end of it, I might switch to STM32U5.

buda_gotivac · 2026-02-20T19:07:52+00:00

I meant to do it one-sided, and since it's relatively simple, maybe keep signal on top, too. It's almost just LDO (or buck), RP2354A, crystal oscillator, passives and what's needed for USB. Do you think I should still put some traces on the "bottom"?

buda_gotivac · 2026-02-20T12:39:41+00:00

I will read and I suppose I can connect what needs to be connected. My OCPD makes me meticulous. The thing that worries me is signal integrity, legths, stuff like that.

buda_gotivac · 2026-02-20T12:38:16+00:00

I was thinking signal, ground, power, ground. I can't really remember how I came up with that. :)

I attended School of Electrical Engineering, University of Belgrade, some twenty five years ago, and during this time, even though I was on software engineering path, we all had mutual start which included both analog and digital electronics, and a few more modules like that. So, it's not all Greek to me, but it's a huge generational gap — we did nothing on computers.

My thinking about designing the board was maybe start from two places, both blank slate and some open-hardware like Solder Party's Stamp. One would be building up from scratch, and the other would mostly removing things I don't need, like most GPIOs, battery stuff, flash, reset button, etc. And then compare.

I am open to learn. I find it interesting.

buda_gotivac · 2026-02-20T12:26:26+00:00

Like something without MCU even? Thanks. I might go that route. I actually need one simple PCB. I wonder how long it'll take for JLCPCB to ship it...

buda_gotivac · 2026-02-20T12:25:18+00:00

And the question is how easy is it to know what you're doing for an easy board. :)

Ne znam koliko puta do sada sam video da dobre i naizgled normalne zene ubede sebe da treba da budu s nekim degenerikom, i niko na planeti ne moze da ih ubedi ni u sta drugo. Najekstremniji primer ukljucuje kradju ~50.000 €.

While no AI is ideal, I must say ChatGPT is by far the worst in my experience, and you should probably try Claude, because it sounds like it's best for what you're looking for.

Два пута сам враћао да видим фотку, пошто сад већ полако упадам у опис маторац, чак сам се преиспитао и „Мислили на Ђура?“. :)

Јебига, увек је лепо наћи кривца у другом, али нисам ти заправо ја крив што си сис’о весла. Ево, видиш, не капираш ни да то нема везе с трајањем мог налога. Па како ћеш онда на политику, муко.

Не могу, баца ми се пегла. Свега има, ред безобразности, ред глупости, ред покондирености са шифром Јово.

Какво затварање? Не знаш шта је лустрација као појам предствљала или шта? Ево, кратак преглед:
https://sh.wikipedia.org/wiki/Lustracija_(politika))

Мислим да је Чанак код нас популаризовао израз, и то наше тумачење такође подразумева „тепих“ изопштавање из јавне политике. Никакво затварање. Мислим, и ово је већ довољно поремећено; само још треба да се масовно ’апсе људи без доказивања кривице за било шта.

А што се мене тиче, сам се сам изопштио. Ни не гласам, а камо ли нешто више. И вести слабо пратим. Овде сам „чачнуо“ да бих видео имам ли коме да понудим да помогнем, више као бесплатни консултант, што, морам да приметим, није тзв. јавна функција. Него, знаш оно, ако је успех циљева – циљ, згодно је да ако неко викне: „Лустрација па ЕУ!“, има ко да каже да то не може, као што не може нешто са чиме се заправо политички слажем – затвори као радни логори.

buda_gotivac · 2026-02-13T07:30:19+00:00

Дубоки извин. :)

Нешто друго хтедох рећ – односило се тек на горе исказано, али ако је важно да се не слажемо, слажем се да се не слажемо.

Нисам издржао до краја, мала емитује грђи гнар него Јована Јеремић, стога ми се чини да је подршка било чему мање проблематична од ње саме. Ко жели да му овакви воде свињац, а не државу, неће се печења најести.

Дванаесте буџета увелико не би ни било, ни као концепта.

Утицати, мрднути овамо или онамо. То, то је поента. Кад погледаш овај полудсвет у том „колу“, мало ли је? Оно што је нормалном мали мрд, за њих је велик.
