There are a few popular mini-standards today, like Wemos D1 mini, "supermini", and T-Display, but it also doesn't matter that they're fragmented because DIP-style breakouts don't need standardization to be valuable - they're smaller, can offer more IO (or less!), and are more breadboard friendly.

Maybe I'm an outlier but I never really understood shields even back when I was using a Diecimila as my main dev board - too many caveats around pin conflicts when stacking them, and rarely was 1 shield enough, so you're going to be using a breadboard anyway.

It's 2025, why are we still making dev boards with an Arduino footprint?!

I think that community can persist independently, and arguably already has since ESP32 launched and Arduino hardware is much less popular.

Does anyone actually use any Arduino hardware newer than Uno R3?

If anything, Adafruit has had the bigger role in community and education for hobbyists lately.

They're called P125-E2, found on AliExpress. I needed the bigger heads for some of the large through-holes.

So far I like these large 2mm diameter pins LOT better than the smaller ones I've used before.

They just gently press-fit into the 3d printed jig so they're super easy to replace if needed.

Bed of nails programming jig and tester coming along nicely.

No actual programming or testing implemented yet, but the presence switch and LEDs are working 😀

The linear toggle clamp is so much better than the cheaper pivoting toggle clamps I've used before.

Chainable I2C drivers for them - based on ATTiny 1-series MCU. Should be launching these soon, but happy to share the designs early if you're interested!

Is that the 60mm soundwell motor fader? 👀 I have a new open source project/product coming soon that might be up your alley...

Bed of nails for an upcoming product... Loving these extra large pogo pins.

life pro tip: you can get free LLM API access by finding people crashing out in Claude Code issues, then looking at network requests from their vibe-coded websites!

Tesla denied having fatal crash data until a hacker found it The data was key evidence in the death of a pedestrian in 2019.

Moments after the collision snapshot was uploaded to Tesla's servers, the local copy on the car was marked for deletion. Then, "someone at Tesla probably took 'affirmative action to delete' the copy of the data on the company’s central database"

This and fuzzy skin need an "outer convex hull" option, as that's often the behavior you want

IC swapped and we've got blinks! Ignore the slightly melted JST connector...

Yeah it's definitely limiting if you're using anything remotely off the beaten path. For my relatively simple designs it's been nice.

(Disclosure: I've been sponsored by JLC in the past, though I was already using JLC regularly at that point)

JLC. I've had mixed quality on some things (mostly an extremely high rate of LED failures), but I can't get away from their part library. It's such a massive competitive advantage since it also means they can provide instant renders of placement/orientation, and stock/pricing is straightforward.

Oops, just realized I had the fab populate the wrong MCU on an initial small run of PCBAs for a new product...

Same pinout, but half the flash and missing a peripheral I needed 🙃

I foresee hot air or a hot plate in my future...

Oh no!

as we all know every programmer's dream job is to never have to code again and instead just manage PRs with unreliable code and communicate with the unreliable entities who wrote it

🤦‍♂️ it was my soldering or my breadboard, causing voltage drop on the supply

Finally restocking some inventory for the Bezek Labs store. $111 import duties on $88 worth of goods. Yup, no choice but to raise prices at this point... 😕

Yellow line does not look like what you want to see on a CC boost output with a static load... 2v fluctuations at ~160Hz.

This is on the Adafruit TPS61169 CC LED boost breakout board - more details on my issue here: forums.adafruit.com/viewtopic.ph...

I'm a boost converter noob - any ideas?

Ok this AI hype is out of hand. This is for a Qi charger 🤦‍♂️

😲 woah this is INSANE!!!!!!!

It's a little too wobbly right now, so I probably need to add a 3rd wire inside for support

Successfully modified my Ikea Tvärhand lamp to use a custom 24V "knot" filament bulb, with ESPHome integration.

Next up is modifying the base to add a dimmer knob of some sort...

Adafruit TPS61169 Constant Current Boost Converter for LEDs The Adafruit Constant Current Boost Converter for LEDs makes driving LEDs easy, whether they're in series or parallel - with a chip that can generate up to 40V and 400mA from 3~5V ...

Adafruit's new TPS61169 board www.adafruit.com/product/6354 is literally perfect for a project I'm working on, but I hesitated ordering while I looked for other things to add to my cart and now they're sold out 😭.

Not available from distributors like mouser or digikey either 😥

GitHub - keyboardio/attiny_i2c_bootloader: An I2C bootloader for ATTiny devices based on AVR112. An I2C bootloader for ATTiny devices based on AVR112. - keyboardio/attiny_i2c_bootloader

github.com/keyboardio/a... looks like maybe a good project to review and adapt for 1-series?

Any tips or things I should be aware of @s.ly?

It seems like maybe there's optiboot support for ATtiny 1, but I believe that's serial-based?

Anything off the shelf for I2C on ATtiny 1 or will I have to learn how to write my own bootloader?

Anyone have experience writing bootloaders for ATtiny 1 series chips? I'd like to have an I2C setup that can:

1) enter bootloader mode from I2C command or via gpio on power up
2) read I2C address offset from jumpers
3) receive/ack program over I2C (or timeout)
4) restart into new program
