Holy shit, the PCB design of this new sensor board, called Ophanim, of CERN’s Aegis experiment just fucking slaps. Right now, there don’t seem to be many images of it on the web, but I hope to see more in the future.

About that BusBoard Prototype Systems SB4 board -- they're expensive. They're more than $6 each (Canadian) plus shipping from DigiKey. They're $10 each plus shipping from Mouser.
That's a lot for a hobbyist when you're experimenting, especially if you're making mistakes.
I looked around again recently, and couldn't find anything I liked at a reasonable price point.
So what does one do in this situation? Well, if you go Overkill 9000, you design your own prototyping perfboard and have a bunch manufactured for you! When you design your own, you can give it any features you like. So this one has:
18 x 36 (648 holes total)
It's two 18 x 18 sections, though I didn't have them scored for snapping.
A total of 6 horizontal busses in groups of 2, at the top and bottom plus one in the middle.
3 sets of 2 vertical busses within that space between horizontal bus sets, similarly edge - center - edge.
Then each row has a 6-hole pad on each side of the center 2 busses, which are spaced for IC or other standard 0.4" component layout.
Made of proper FR4 fiberglass. Good copper, good soldermask.
Silkscreened row and column IDs on both the front and back, at both the start and end of each row/column (and they match up with the back...).
And silkscreened boxes on the front showing the pad/buss pattern - no more flipping!
They arrived today and ... they're beautiful.

First Look at the Bare Liberux Nexx PCBs
Our redesigned prototypes have arrived completely bare! These are the raw PCBs, fresh from manufacturing, before any components are assembled.
It’s been a long wait, but they’re finally in the hands of our assembler! Now, we’re excited for the next step: having them fully assembled in our hands. 
Stay tuned for more updates as we bring Liberux Nexx to life! 
One of the final modules for my #StackSynth project: the #noise generator. It outputs white, blue, and pink noise and uses a #3904 and a #TL074 with a lot of resistors and a couple of capacitors.
It is based on Moritz Klein's video: https://youtu.be/0yB_h_wFkh4
I prototyped it on solderless #breadboard and then designed the #PCB in @kicad and let @aislerhq manufacture them again. It turned out quite nice and sounds great.

Lekce pájení SMD součástek pomocí pájecího pera.
Není to věda, jen to chce grif. Pak to jde jako po másle.
Základem je kvalitní páječka, pájka, správně nastavená teplota a klidná ruka

And just like that we have a functioning clock! currently running on a propmaker RP2040 but I will probably have to move over to something WiFi enabled before long #pcb #electronics #maker #RP2040 #RaspberryPi #jlcpcb #circuitpython @adafruit
Electronics tooters, do you prefer JLCPCB or PCBWay?
They said this wouldn’t work but it bloody well does! Just three more digits to solder up (161 individual LEDs!) and I’ll have a clock!
I’m so glad it does work though because I ordered two hundred of these pcbs 
XoomFloppy als USB-Kabel
Die ZoomFloppy war mir immer viel zu groß. Daher habe ich in der Vergangenheit einige Projekte gestartet, um das Ganze auf eine wesentlich kleinere Größe zu reduzieren.

I think I found out why these proto boards were so cheap...
The row and column labels on the top side don't actually match the ones on the bottom side. Column "L" on the top is "N" on the bottom...
Nerding out at Hackaday Berlin 2025! @geekmomprojects I finally got my own bendy dude!
Today I found out about the "replicate layout" plugin for Kicad.
I was looking at repeating a block 64 times and thought there must be a better way.
I'll have to spend some time seeing what other goodies are in the plugins section. I really wish I'd seen this in the past.
There is a great video showing how it works.

Next step finished: #soldering the #pcb that arrived this week.
I had to drill two holes that I forgot to add to the boards. But there was only the ground plane at that position.
Again, they were manufactured by @aislerhq

Nice looking Oshpark boards. I still miss the stickers

One of the connections between the AC input in the #sonoff switch and the output was a black wire. I simply desoldered it.
The other was a #trace on the #pcb. So I cut it with a knife. Deeply.
But it still was connected! There was an identical trace on the other side, difficult to reach. So I grabbed the #Dremel and cut a giant hole on that poor pcb
That is rough. And ugly, and unsafe... but it works perfectly!
Tested the switch with the tester: not only it still works, but the two "output" terminals are disconnected from the mains and now they behaves exactly as if there was a switch between them!
