Everyone needs to understand what Elon and DOGE are building, an AI driven panopticon that will know everything about you and will be used to ensure compliance with their fascist agenda. They are creating a unified database of everything the federal government has on every single American. 🧵1/

It's up for sale! Grab yours today! The ATTINY PRO is a small-but-capable ATtiny3217 development board with a form-factor similar to a Pro Micro. It's like the original Arduino board, but with the much better peripherals of the Tiny AVR 1 and 2 series. www.tindie.com/products/mat...

The Raspberry Pi Pico came out just over 4 yrs ago. At the time, we had shelved a project we were building - it was good but we didn't love the boards we were using. When the Pico came out, we brought the project back & worked fast to finish it. Happy Pi Day / 4th Birthday make.playpiper.com !

Hi Electronics Bluesky! I made a new module for my Tindie store (and honestly, for me to use too!) It's a dev board based on the ATTINY 3217. It has an onboard CH340 for both programming via UPDI and for UART<>USB. I love these chips as I2C peripherals. Tindie.com/matzelectronics

Eepy puppy

I talk about race, openly and honestly. It's also what I do for a living, and while it can be uncomfortable for white bodied people to hear criticism aimed at white folks. If we are to move together as a society, it requires getting real and moving past the fragility.

what a surprise. 🙃

New Tindie.com/stores/matzelectronics products in development! These are all capacitive-touch PCBs. Left one is a track pad, middle is a keypad, and right is an iPod-style rotary wheel.

DOH! Forgot to check the box to remove the order number. Ugh.

Trying to design an input stage for an ESP-32 based scope. Haven't had to bust out my own scope in a while. It amazes me how quickly this analog stuff can get complicated! Just trying to attenuate and bias a range from +/- 5V to 0 to 3.3v, and I'm 4 op-amps deep.

I made a new thing! Here's a four digit 7-segment display module. It's nice and bright, and it's designed to be connected via I2C (STEMMA QT, QWIIC). Firmware is open source and written in Arduino so it's easy to modify to fit your needs. Available here: www.tindie.com/products/mat...

Woot!

Trying out my not-yet-finished mechanical keyboard this evening. It's my first mechanical keeb...it's going to take some getting used to, but I think I'll like it! Not sold on using CircuitPython yet. A couple of weird issues that I have had to work around. I think I eventually land on Arduino.

18 transistors and a boost converter later, and it's working! I wanted a display with large digits and the dots in a clock config. It took a bit to source one & the company sold me 25 as a sample order. I didn't read the datasheet carefully enough. The segments need 6V and the dots need 3V.

Making progress on the hardware hacker keyboard! The 128x32 OLED screen will fit well along the top row. I just ordered the shell, which will have integrated stabilizers for the large keycaps. Still finalizing the controller and USB hub PCBA. That will connect using an FPC cable.

I hope everyone had a wonderful day of rest today. I decided to do the Black Friday sales thing and offer 10% off at my Tindie store. Here's the shameless plug: I sell a replacement kybd for early Apple IIc computers & a nifty USB Host module: Use code MATZ10%OFF www.tindie.com/stores/matze...

If you’re still masking - thank you. If you’re cleaning the air - thank you. If you’re staying home when sick - thank you. If you realize vulnerable people are just as worthy of safety and survival as everyone else - thank you If you’ve refused to toss us aside for “back to normal” - thank you.

I'd love to be a part of this!

Does anyone know of a good solution for stabilizers with low profile keyswitches?

I had a lot of fun designing the keyboard replacement for my Apple IIc (which you can buy on Tindie.com!). I might just be hooked on this custom keyboard thing...so I'm thinking of building a "hardware hacker" keeb. A modified 1800 layout with an OLED screen, a USB Hub, and voltmeter. Thoughts?

a little bit of cleanup for the files and I think i can be done with this project, still some things to test but shouldnt be anything too major. #chippydootles

🧵 Here is some *wonderful* news that will make your covid-conscious day 🎉: Per CT state senator Matt Lesser (democrat) 8th grader Eniola Shokunbi has secured $11.5 million in funding for school CR boxes. Below is a photo of Ms. Shokunbi & Sen Lesser, from his FB page. 1/8

AI would be easy to kill. Pass a law saying that the owner of the AI corporation is as legally liable for what AI says as if an employee said it.

Doing radio stuff. Trying to make i2c radio modules. Making slow progress, but my brain hurts.

Hi! With all of these new followers, I should introduce myself. I'm Matt. I'm the lead engi-nerd at PlayPiper.com. I get to make cool stuff for kids every day! Fun fact: make.playpier.com is pure HTML/JS/CSS. No frameworks! I like it that way ;) It uses a RasPi Pico & CircuitPython too.

It's finally done and ready! www.tindie.com/products/mat...

After a few months of iterations and prototypes, it's finally ready! I've listed the Apple IIc replacement keyboard for sale here: www.tindie.com/products/mat...

I'm working on a replacement keyboard for early Apple IIc's. Is there are market for this as a DIY kit?
