Hello! It has been a little while, but #nakeddiefriday is back in town.
Today's exhibit is an old PIC1650A. Yes, one of *the* PIC series of microcontrollers. Note it was designed by General Instrument in 1980. It was fabbed in a single metal layer, metal-gate NMOS process. The image is about 4.3x3.8 mm.
No full-res link as SP is still borked.

ICE and CBP face-scanned 100,000 people last year. So EFF is proud to support Senator Markey’s “ICE Out of My Face Act,” which will stop these agencies’ biometric surveillance. https://www.eff.org/deeplinks/2026/02/yes-ice-out-my-face-act
A Kraftwerk tribute that someone did on their Amiga using Brilliance 2. I'll have to check out that program!

I'm so proud! #Sennheiser never would have allowed a #garage-built #proton-pack to make it in to their behind-the-scenes video! (That's me starting at 2:36)

For contrast, don't miss the Sennheiser #Spectera video.

I'm doing the next generation protonpack #fpga telemetry system as an #opensource #openhardware design.
Team #mastodon will help me out, right?
Huge thanks to @Unixbigot for troubleshooting my #bass amp. It turns out that no magic smoke was released by me, only stray electrons via a loose connection.

So, I've been working on reconditioning an old leather wallet, but it doesn't have RFID protection. Here are some #DIY hacks for making whatever you carry your cards in safe against hacking! (And yes, I plan on trying out the duct-tape version and testing it out this week!)

Mr. Carlson acquired an instrument tuner. It doesn't just use vacuum tubes, it uses vacuum tubes, a custom pulsing neon tube, _multiple_ very custom transformers, a giant hidden reference tuning fork, a motor, and a 12-speed transmission gearbox, and it came to him fully working and _recently in service_.
Basically if you're into holy shit old electrics, you will probably enjoy this:

(for reference, you can get phone apps for this, or you can buy little dedicated standalone devices the size of... idk, a thick credit card, or also the kind that's smaller and has a clip pickup that attaches to your instrument head. BUT NOT IN 1930)

Then a neat project to build a seven-segment clock out of nothing but a crystal and a bunch of discrete CMOS logic chips - schematic available if you want your own!

For the #sustainability crowd, a work-in-progress open-source solar micro-inverter - designed to be easily understand and reproduced locally for deployment in 230/240VAC regions.

It's #Hackster round-up time once again, and we're starting with the article I actually wrote last today: the news that Texas Instruments is spending a whopping $7.5 billion to acquire Silicon Labs lock, stock, and barrel.

My PC doesn’t indicate when it’s sleeping, so I hacked together a small device that monitors a USB port and uses that to figure out if the computer is sleeping or not. Of course since I had some glow in the dark LEGO spiders kicking around I stuck one of them on the LED.

"stable 220V DC output". yeah, nah. Oscillator, step up, and full bridge rectifier. Works well, but totally unregulated😁
Whoever invented this method must be a genius. This was a portable calibrator for high-voltage partial discharge testing. Because of HV, it was battery powered and insulated from the mains. But sometimes the test signal needs to be phase-locked to the 50/60 Hz AC mains frequency, and the solution was:

Rather more welcome news from the world of #science next, as engineers develop a chip capable of turning waste heat into useful computation - which could mean more efficient computers.
Maybe. If it scales: they haven't proven it can be used for more than a single operation yet...
The Serial Wombat 8B ecosystem - cheap WCH RISC-V microcontrollers loaded with an open-source firmware and installed on boards that act as smart dev-board expanders over I2C - grows four boards larger now, as Jonathan Broadwell launches a new #crowdfunding campaign.

First #Hackster round-up of February. Let's see what's keeping me busy today!
First up, something I mentioned this morning: the second price hike from #RaspberryPi in the last two months. This time the $25 added to top-end SKUs is joined by another $60(!). Why? Well, the AI bubble: RAM is expensive now, everything has RAM, so everything is expensive.
It won't be the last price hike of the year, either, I'll tell you that now.
