I couldn’t find conductive fader caps (for touch sensitive motor faders) off the shelf, so I tried 3d printing them and now they’re available in my Etsy store. (These are an accessory for a product I’m hoping to finally launch this summer…) bezeklabs.etsy.com/listing/4501...

Has anyone implemented a heat set insert mode on a 3d printer? It seems silly to have a dedicated tool with hotend (soldering iron) and a linear stage when those are built into the tool that printed the part you’re inserting into…

Next phone ended up being much sooner than expected - 6 days of trying every tip online, an hour on phone with carrier and google support, and no solution identified, so I bought an iPhone after 14y on Android. Google wastes billions on AI many people don’t want but can’t make a basic feature work.

Google RCS is so awful that I'm 90% certain my next phone will be an iPhone. Switched carriers and 3 days later still locked out of group chats. Absolute own-goal by Google, but I think they'll even admit that they have literally no clue how messaging should work (cough Messenger, Allo, Talk, Duo)

Can't find a single legitimate retail source for conductive fader knobs for touch sensitive linear potentiometers (not even replacement parts for very popular digital audio consoles!) - so many listings that claim "touch sensitive" are just lies with zero conductivity.

Back in my day, AI used to stand for Adobe Illustrator! And we hated that, too!

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

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.

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!

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" arstechnica.com/cars/2025/08...

Tesla denied having fatal crash data until a hacker found it

The data was key evidence in the death of a pedestrian in 2019.

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

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...

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

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?

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... 😕

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

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...

I'm going to continue the Molnart bulb teardown soon, but in the meantime I started modifying the TVÄRHAND lamp base. First up was removing the E26 socket (labeled E258238). Very tricky to release both clips simultaneously with no access to the sides, and limited clearance for tools.

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 😥

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 ...

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

There are many reasons why American plugs are poorly designed, but I love being able to "lock out" a plug using the holes when I'm working on the other end and want to avoid accidental plug-ins. Normally I use zip ties, but a twist tie is better than nothing to signal "don't plug this in!"

Ikea has a bunch of cool filament decorative bulbs (Molnart) but they aren't dimmable, so I'm exploring converting them (and the lamp) to low voltage DC and controlling with esphome. Seems nicer than 120v triac dimming too. Anyone have tips/experience taking them apart without shattering the glass?

Randomly decided to run a Father's Day sale halfway through the day 😂 Get your DIY Split-Flap parts 10% off for the next ~12 hours: bezeklabs.etsy.com (And this is all pre-tariff inventory so this is likely the cheapest things will ever be again...)

I've seen weird "brand" names on Amazon before, but this was a new one!

A bit of a scary failure mode on this Whirlpool microwave - the main power relay got stuck on so it just runs the magnetron continually as long as the door is shut (listen to the buzz). When it failed it basically just kept running even after time was up - luckily we hadn't walked away.

Is there anything like cleco fasteners but for attaching probes to through-hole test points?

Parts with modeled threads can't just be mirrored and printed 🤦‍♂️ Realized my mistake about 10 seconds after the 4 hour print completed

It's been a while since I did some research and test rides, but is a Tern GSD still the solid choice e-bike for kid/grocery hauling? Have other long tails caught up to the GSD in terms of quality/convenience? Should I be looking at bucket bikes? (I disliked Urban Arrow test ride previously)
