@3dprinting This morning I soldered the FilaBilly dehumidifier PCB. I need to crimp up some connectors, reprint the orange standoff/surround (it's like 0.3mm too tight), and finish the firmware. Then it'll be system testing time! I already know the ESP32 boots, either from USB or 12V power.
I found out about r/PrintedCircuitBoard yesterday, so I'll ask for a PCB review there, even though the board is assembled.

Nice looking Oshpark boards. I still miss the stickers 😕 #oshpark #opamp #electronic #filter #Schematic #PCB
Anybody know how to get a semi circle edge cut in #KiCAD with #oshpark? I tried to get a connector's key cut but oshpark didn't drill it. Do I need to place an nc via here?
@recantha using KiCad is an art. It's relatively easy to learn, and getting your first PCB from #oshpark is not too hard (and rewarding). Designing for low-cost prototype services is more difficult. Using the correct design rules, using supplier component databases, balance default components with special components (if available), label them correctly, double- and triple-check orientation of, e.g., diodes...
Having an up-to-date guide certainly saves time (or money).

We were excited to see our friends at the Portland State Aerospace Society (PSAS) team up with #SpinLaunch to test the limits of OreSat: https://blog.oshpark.com/2024/12/21/introducing-the-worlds-first-ruggedized-satellite/ #oshpark #portland #pdx
Allison Parrish wrote about their journey to add a hinge to the Game Boy Pocket. The design of a flexible PCB played a pivotal role:

I also tried to have #OSHpark bid my #PCB fabrication.
Their website claims to support #KiCAD files directly, but it choked because I'm now on #KiCAD8 , which was released about a week ago.
They also wanted more for 3 pieces (with soldermask only available in their trademark purple) than I paid for 8 pieces (in my choice of color) through one of my old favorites, Colorado's #AdvancedCircuits ( 4pcb.com ).
First attempt at designing a custom PCB and having it printed. Plenty of lessons learnt but it works! #KiCad #OshPark #RaspberryPi

The ExADXL breakout board makes it simple to mount an ADXL module, or multiple ADXL, to a Raspberry Pi Pico. This is a popular approach to adding extra resonance measuring instruments to a Klipper-controlled 3D printer.

@rc2014 BTW it's available for ordering from #OSHPark https://oshpark.com/shared_projects/Ux20E03D
For a bit of research yesterday I uploaded gerbers to a few of the well known budget PCB fab houses. JLC, DirtyPCB etc... two things I found, one is that if you're working on smaller boards less than 2*2cm and not in a particular rush nowhere is cheaper than #OSHpark. Also all the services are now really slick at file upload/rendering/ordering. I remember lots of pain with many services say 6-8 years ago!
The #CircuitPython driver for the AD5293 Digital Potentiometer is a wrap! This is the 100k-ohm version that's in short supply, but DigiKey currently has a bunch of the 20K-ohm chips in stock. The chip works nicely with single or dual power supplies from +/-9V to +/-16.5v. The driver is available in the @adafruit CircuitPython Community Bundle or in the repo (https://github.com/CedarGroveStudios/CircuitPython_AD5293). The PCB is perfectly purple #OSHPark.
I have an idea for a project that requires, among other things, an accelerometer, and which must weigh very little. I designed a breakout board for the LIS3DH today and sent the design off to #oshpark. I recently acquired a hot air station, but have never hand-soldered an LGA package before. It looks challenging. Excited to try!
KiCad files, for anyone interested: https://github.com/jedp/LIS3DH-breakout
