A 2nd hand treasure, a car radio/kassette, - it works perfectly; 4 channel amp... I might not split it into components, and simply use it as a hifi.... Hm...

I've got a #QMK mod for my #Kinesis #Advantage2 LF #keyboard: https://karl-voit.at/2021/05/23/advantage2-modifications/

The mod is using a Teensy+ 2.0 chip:
https://michael.stapelberg.ch/posts/2020-07-09-kint-kinesis-keyboard-controller/

I've got weird effects over the last weeks: left Alt-key not working (independent of its physical position/mapping), order of keys is mixed up when entering, sometimes a sluggish delay when typing text. Could be related to KDE Plasma (X11 and Plasma on 2 hosts) or keyboard hardware, I don't know.

Could it be that after 5 years the Teensy chip needs to be replaced? 🤔

Maybe the dampening (see first URL above at the bottom) did cause some overheat?

The keyboard is powered 24/7.

And if so: where do I get a #Teensy++ 2.0 chip these days? (Or I might to Teensy 3 or 4 which should be possible as well ...)

I've got a #Kinesis #Advantage2LF #keyboard. I switched PCB to the #kinT alternative using a #Teensy controller in 2021-02 to get #QMK firmware:
https://github.com/kinx-project/kint

Since a few weeks, I face issues: ESC switched its position with the ` character. I "fixed" that by swapping their definitions in the keymap.c file & re-flashing. Weird but that worked.

Since a few days, they were swapped again. Swapped them back + flashed to their original definition position. Fixed.

However, there's another issue I can't fix: the Alt-keys are behaving erratic. See their position on https://karl-voit.at/2021/05/23/advantage2-modifications/

The left one is not doing anything at all. https://keyboard-tester.com/ doesn't show anything when they are pressed. I don't know if this is OK for that kind of modifier. The right Alt key is working sometimes.

Both were mapped to KC_LALT. I tried to flash both with KC_RALT which didn't change anything.

Could it be that the Teensy controller got faulty?

Any other ideas?

My recent build of a #chorded #keyboard, a clone of Chordite. Work-in-progress firmware in #rust and (still some) C at: https://github.com/akavel/chordite-rust

Planned next steps:
- practicing actually typing on it... (the hardest one);
- tweaking and "improving" the layout and functionalities (a neverending story?) - interested in anyone who might somehow help make some sensible one given the constraints of the device;
- hopefully adding mouse functionality based on a gyroscope module (some "MPU6050" board is on its way) - will it work fine enough?
- maybe one day wireless through BLE?

Once I have the mouse functionality built and added, my main goal is to try and be using it with #XReal One glasses I bought recently.

Thanks @rahix for avr-hal; thanks @PaulStoffregen for #teensy; thanks John W. McKown for creating #Chordite, thanks @rustembedded for helping make Rust on embedded possible; thanks my amazing friend for soldering it for me, and thanks many others for many other things.

I'm a bit disappointed the Raspberry Pi Pico draws too much power to be used as a USB HID device with an iPad or iPhone. This is something I used to do with the Teensy LC quite easily. (Luckily I have a *ton* of LC boards on hand!)

It can work with a powered USB hub but that's a lot of faff.

Just got word I'll be receiving a #Teensy and @carlorovelli 's book on White Holes for Winter solstice gifts. I'm psyched, but challenged to forget this so that I may be psyched again in a month. #whitehole #cosmology

It seems I underestimated how much time it would take me to get these done with dayjob and family, but I finally got four #MCL64 ready for testing. I hope they all work.😬

Two #MCL64 almost finished.
I'm still waiting for the correct 10 μF caps.
If you want one, let me know.
I still have parts for two more.
