So far, I’ve always used those very expensive 1/8” Micro Cutters from LPKF (22€ each) for PCB milling. These tests with an 8€ replacement actually look quite decent.
Milled PCB. Two TSSOP-16 landing patterns beside each other, connected with traces (same width as pads though). Spacing between pads is about 0.12mm.
An engraved DIN font. 0.1mm width.
The TSSOP-16 (with a 3x3mm cooling pad in the middle) in a larger circuit.
Four small breakout boards milled on a large PCB. Just SO-14 patterns and two 1206 for a PIC18 test.

Turns out it's cheaper (and far more fun) for me to bulk order blank PCB from @jlcpcb.bsky.social than it is to purchase 1oz copper clad fr4. They arrived in about 5 business days!

Kto odpowiada za chemiczną bombę tykającą przez pół wieku w murach uniwersytetu? Sprawa jest prosta. North Carolina State University pozywa Monsanto (dziś w rękach koncernu Bayer). Powód? Toksyczne polichlorowane bifenyle, znane jako PCB, w materiałach użytych do budowy gmachu Poe...

Griff the USB microphone finally got his own device page (like a product page but he isn't a product), linked from the QR code on the revised Griff Mini PCB : www.pippyg.com/griff.html

I'm looking at this area of a ThinkPad motherboard with illicit intent.
A small magnified section of a ThinkPad motherboard PCB. A large unpopulated connector labeled "JTAG1" is visible with a "Lenovo ThinkEngine 62D518FTG" IC chip below. The board also features a selection of resistors, capacitors, and other small components which are not the main focus of the image.

As the other part of preparing to learn how to design an analog synth I created my first little PCB which was a great learning experience. I made a little tiny breakout to an io expander :>

I'd like to shoutout @pcbwayofficial.bsky.social for sponsoring this run of my #ArduinoX86 V4 boards. The FPU board is my first 4-layer board so I'm hoping I didn't make any fatal mistakes. #retrocomputing #emulation
Two purple PCBs for the ArduinoX86 project - supporting a 386EX CPU and a 387SX FPU respectively.  The boards are laying on a silicon mat on a workbench.

so apparently the Digiblast actually outputs RGB video through the TV-out port which is converted to composite via an AD723 chip. times like this I wish I had the soldering and electrical engineering skills necessary to make an actual RGB cable so I could capture in much higher quality.

Building a custom PCB for this sounds like so much fun. But it also is far more complex than anything I’ve ever attempted. Should be a great learning experience.

We cannot be fully sure why Youmu's eyes are coloured blue after Perfect Cherry Blossom, but one theory is that Youmu attempted the Blue Lemon Challenge inbetween the events of PCB and Immaterial and Missing Power.

Ultra homie gave me their old PCB split keyboard. Now I'm knee deep in ZMK stuff trying to make the right half a shortcut pad for Blender/Krita! #pcb can't get any zmk gui apps to connect 😩 should probably just follow the doc and make the repo. new to this

A pic of the 50 MHz custom laser driver/receiver frontend from earlier in construction. Really terrible solder paste application but I don't use stencils.

Just did an end to end test of our laser driver (built without any commercial driver ICs) and receiver, good to 50 MHz which is good enough.

Im pleasantly surprised by how roomy the Kworld SA235 is. It also has labeled large test pads for the video signals, ground, and power. I wonder how I can get an internal feedback loop setup. Something akin to lofifuture's VGA feedback gen, but in a smaller package. #HardwareGore #CircuitBending

Someone on arcade projects reverse engineered the schematic for the Nanao MS2930, one of the best later era arcade monitor chassis. www.arcade-projects.com/threads/crea...
Hello,

The goal is to do it from photos and a real pcb.
Photos because I need a little help to build an initial component list.
I already have the script using this future partlist to create a KiCad skeleton schematic.
(switched to some fund me support)
Thank you
90% done. At least every component in the spreadsheet is in place. I don't think I forgot some.
Logic of the design is also OK for me , no strange things (or missing links).

what is left to do
-caps values
-zener voltage
A lot of them can be guessed from ms2931 MS9, ...

Got my Tecmar Mac Drive working after recapping and repairing the power supply and replacing a shorted cap on the main PCB board. Very cool serial based drive that was available BEFORE Apple's HD20 hard drive solution. #Macintosh #vintagecomputer #retrocomputing
This is a picture of a Tecmar 10 MB Mac Drive that works on a Mac 128K computer.  It boots from floppy but spits out the floppy as it's booting and continues to boot from the hard drive.  It has an early Syquest drive that takes a 5MB cartridge.  I don't have one of those, unfortunately.
