@petejohanson @glitzersachen @mjdxp obviously, the #DIY #keyboard community enbraces modularity and opensource, so if you want to wire a real planes' cockpit buttons to a #Teensy keyboard matrix and have it spit out your custom F22+Ctrl+Alt+? keybind for the APU START/STOP button on the ceiling, you can!

And if #DIY is too complex and/or you want someone to build you a working configuration and give it a "White Glove Delivery" to your home I may know someone.

  • Just bear in mind that that's gonna be expensive, so unless you are a regular visitor at a professional flight simulator training center and propably are on a first-name basis with the staff there, you may underestimate the cost of such a setup.

But then again, I do know that hardcore simulator fans that solely play their one game will go *above and beyond in terms of decking out their setups and my #weebness & #nerd-level is way too low to guide them!

Important milestone for my timecode gizmo: this is the first successful syncing using a cell phone and the Teensy board implementing an USB audio device, plugged as an external mic into the USB-C port. This is important as I'm pivoting my project toward youtubers rather than indy cinematographers who are already using overpriced and counter intuitive SMPTE LTC generators in their workflow 😏

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

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.

So thinking about designing and building a guitar effects processor... It would be limited to only doing time-delay / reverb / modulation effects, so no digital modeling of amps or distortion, etc.

I figure there are two different paths to take here: small ARM-based computer like a Raspberry pi 2/3/4, or a microcontroller like a Teensy 4.1 or even an ESP32.

I'd like enough horsepower to be able to have a couple of delays, plus say, a chorus running at the same time. Also, I want it to be MIDI-capable.

Note: if I go with the Raspberry Pi, it won't be running Linux. I don't want to wait for Linux to boot up or be shut down properly every time I use the pedal.

What's the general consensus out there on which path to take?

Most #LED #artwork uses simple trig to convert assumed pure red/green/blue into colors (talking flood lighting, not computer monitors).

I wrote a library in 2015 to do this in #CIE #colorspace on an #Arduino (well, a #teensy from PJRC). This gives perceptually even hue and saturation shifts (brightness is trickier with LEDs). But I forgot to post it anywhere until now...

Okay I've gotten the lights just so, and my third annual Internet Tree is live! Go to tree.c9a.dev to change the lights on the tree in my living room, and watch your handiwork on the livestream. You can also just watch the show at stream.cincodenada.com

Streaming with @owncast and built with @glitchdotcom. Hardware is #ws2812 light strings driven by @PaulStoffregen's #Teensy with a #Python helper for the internet bits because I haven't moved those onto an ESP32 yet :blob_smilesweat: #owncast #livestream

@Siff The electronics are assembled now. Not the cleanest, but acceptable.

The metal plate is a cover for a ceiling junction box. It's a heatsink for the LEDs. I ground out a hole using a Dremel cutoff wheel -- that was the best tool I had on hand. And I dropped it while the thermal adhesive was wet. That's why it's smeared all around.

Still, I'm my own worst critic. It's just fine, and I'm sure the recipient will love it.

Here's the long overdue video for track 5 on my #DAWlessJams1 EP, entitled Werk It (it was my first proper Moog Werkstatt track).

It also features a #Teensy as a serial to USB host MIDI converter, so I could use my JP8000's arpeggiator with the Werkstatt (via an Arturia Beatstep as MIDI to CV converter) and a weird DSP Effects unit from China.
