I tell ya, I really love wireless charging. It is so convenient and even better, it’s easy to create a wireless charging solution for your project too! Personally, I like the BQ51050 though there are a ton of great options out there. :)

Looking to get PCBs made in Europe? 🇪🇺

Here are some alternatives:

AISLER: 🇳🇱 Company, Boards are made in 🇩🇪 (apart from special orders), affordable prices but only offers simpler options, ideal for makers.

Beta Layout: 🇩🇪 Company, most PCB configurations are available with 🇩🇪 manufacturing. Somewhat higher cost, Free stencil with PCB order.

Eurocircuits: Manufactures in 🇭🇺 🇩🇪 , higher prices but also offer advanced options like micro via etc.

I’m working on getting through some of my parts inventory. I built up 5 new RPGA Feather and have them available on my Tindie shop: https://www.tindie.com/products/34743/

The RP2350B is now available on LCSC! https://www.lcsc.com/product-detail/Microcontrollers-MCU-MPU-SOC_Raspberry-Pi-RP2350B_C42415655.html?s_z=n_Rp2350B

@adafruit okay, I had to scratch the itch since I have two of the ICs on hand. I designed a board 😅

@adafruit any plans to do a stemma board with the BMA530? :)

@signalskew any chance you make this a GitHub template?

They’re NEOPIXEL compatible which makes them perfect for your next LED project :)

One of my favorite boards to have made in my time running Oak Dev Tech has been the 5x10 PixelLeaf matrix. I have two left that I’m looking to get rid of, you can find them here: https://www.tindie.com/products/oakdevtech/5x10-pixelleaf-rgb-matrix-sk6812mini-rgb-matrix/

Edit 2: Y'all are gonna need to try harder.

Edit 3: Still holding up pretty well, even with how hard y'all are trying! This is a little Beelink mini PC I got for $12 when Amazon sent me the wrong item and wanted me to pay to send it back, hosted on a home fiber connection. The jump in processor power really cut Sharkey's response times and lets my reverse proxy Traefik keep up way better. I think it was HTTPS on a 12+ year old Intel desktop chip that was really doing it in.

If you’re a US maker struggling with the cost of PCBA overseas with the current uncertainty with de minimus, feel free to reach out. I do small batch assembly here in the US. I’ll source PCBs, Stencils, and parts for you at cost (material + shipping), and assemble for an affordable hourly rate.

I’ve done it for a number of makers in the past (and still regularly for one maker).

I do it all cost plus to keep it as affordable as possible.
I even do design work too.

Periodic reminder to the fedi EE / embedded systems community: I have a lot of lab capabilities and resources that the average hobbyist can't afford, and am willing to offer them up on reasonable terms (i.e. FREE in many cases) to help people out.

As a general rule if you're not making money on it (i.e. hobbyist/noncommercial/academic project) and it's not a major time commitment or consumable cost for me, all I ask is that you pay return shipping if you want the hardware sent back to you afterwards. For anything large or commercial in nature, I'm still potentially interested but we'd have to discuss compensation first (I offer steep discounts vs industry rates as long as you're not making a profit from the project... think $25-50 an hour for something an industry lab would charge several hundred for)

Also open to hosting occasional lab sessions for folks in person on weekends if you're Seattle local and willing to head across the water.

Capabilities and equipment available:
* 3D planar EM simulation (Sonnet Pro)
* 5 3/4 digit multimeters (R&S HMC8012)
* Various oscilloscopes to 16 GHz BW (PicoScope 6424E, LeCroy WaveRunner 8404M-MS, LeCroy SDA 816Zi-A) plus power rail, current, and differential probes
* VNA measurements to 8.5 GHz (PicoVNA 106 / 108)
* BERT BER/eye pattern/bathtub curve measurements to 28 Gbps (MultiLane ML4039-BTP)
* Vector signal generation to 6 GHz (Siglent SSG5060X-V)
* Fine pitch soldering and PCB rework, BGA assembly, inner layer circuit edits, etc
* UV-VIS-NIR (200 - 1200 nm) spectroscopy
* Low magnification stereo microscopy
* High magnification reflected light optical microscopy to ~300nm resolution, including large area automated step-and-repeat scanning and stitching of multi-gigapixel datasets
* Coming soon (purchase order sent to vendor, estimated ship date is early April): Embedding and cross section polishing for failure analysis etc

Hey folks, I’m clearing out some inventory from closing down the business last year. Just a handful of items marked down 20% https://www.tindie.com/stores/oakdevtech/

It's the final countdown! No major issues in the next 12 hours == v9 release!

@adafruit Recently I added supervisor.runtime.display to CircuitPython. It's the new-and-improved successor to board.DISPLAY which allows you to use python code to configure a primary display that is kept across runs of code.py.

Today, I wrote up a note explaining how to use it in more detail: https://adafruit-playground.com/u/jepler/pages/supervisor-runtime-display-in-circuitpython-9-2-5

@azonenberg now I’m imagining someone saying goh-re-yuh

BREAKING: We are suing DOGE and the Office of Personnel Management to stop the brazen and illegal data sharing of federal employee data with the “government efficiency” group. https://www.eff.org/deeplinks/2025/02/eff-sues-doge-and-office-personnel-management-halt-ransacking-federal-data

They say that history doesn’t repeat itself, it rhymes. And I’ve said the last decade or so that those who remember history are cursed to watch others repeat it. We’re living it. Enter the American refugee.

@stylus fights to end fascist government takeovers (edit: I can’t type to save my life)

Hi, I'm a computer programmer who is too old to hire in the US. Looking for any jobs in non-fascist countries. I can do all sorts of wackadoodle things with computers and am also quite stylish.
