#teensy — Public Fediverse posts

I build my first #teensy project for $dayjob and it brings back a lot of things I dislike about programming and hardware. Built around a pretty popular tutorial and repository. In only 4 years some very tiny things have changed, that made the 2h job a 4h job.

That said, the teensy plattform is super powerful and the hardware is easy to extend/work with.

Some people who had problems with the guide I used did suggest raspberry pi solutions. Something I would not want to leave unsupervised.

Next will be repurposing an old phone as housing for this little recording setup.

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...

Working on an 'acoustic synth'. I've ordered components to make physical small percussive hammers, e-bow-like elements, and transducers. Here, I'm testing out a transducer, using #littlebits by #korg as an #analoguesynth sound source... The end goal is a generative #electroACOUSTIC perpetuum mobile, to be installed outdoors in an eco-village, Hyllegaard Høje, Hvalsø, Danmark. #Teensy #Solenoid #diy

The technology we experience as children can have a lasting impression. An algorithm that Mate Steinforth saw at a relative's house had such an impression that three decades later it drove the creation of a #Teensy based realization in LED form

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 ...)

#maker #electronics #teensy #makers #hacking

Fans of Adafruit may recall a couple of months ago that one of the key people at the company made a series of posts on social media (including Mastodon and BlueSky) that looked awfully like online harassment. Besides some unprofessional stuff like name-calling, there were more serious accusations such as transphobia and doxxing.

Now, it seems there's been a falling-out between Adafruit and SparkFun Electronics. SparkFun has taken things seriously enough that they've ceased their business relationship with Adafruit. Here's the Official Response from SparkFun, citing a direct violation of their Code of Conduct:
https://www.sparkfun.com/official-response

This is bad news for Adafruit, since SparkFun is a major supplier of electronic components, tools, and devices. SparkFun also manufactures their in-house range of products, as well as having the scale to manufacture products for other companies such as Teensy. It's potentially fatal for Adafruit to get cut-off from SparkFun.

The response from Adafruit has been confusing. Rather than explain how or why they destroyed their business-relationship with SparkFun, they made a public statement announcing they'll soon cease selling Teensy devices: "Discontinuing the Teensy at Adafruit" (https://blog.adafruit.com/2026/01/12/discontinuing-the-teensy-at-adafruit/)

To make matters even more strange and confusing, Adafruit announced they're making a Teensy-knockoff^h^h^h^h^h^h^h^hcompatible board.

But, surely the most bizarre twist is this same individual from Adafruit has gone onto the Teensy forum to advertise their new products meant to compete with Teensy: https://forum.pjrc.com/index.php?threads/open-source-teensy-compatible-what-features-do-you-want.77584/
I think it's fair to say that Paul Stoffregen, who runs/designs/engineers Teensy, has shown remarkable restraint since being dragged into this drama and having it jump tracks and go careering outrageously onto the Teensy forum.

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?

I would like for this to be the accurate take on #Arduino developments this year. As much as I've already kinda moved on myself (#Teensy is the centre of most projects these days, but I'm studying up on FPGAs cause the stuff I'm thinking about, such as ADAT Lightpipe audio, is pretty exotic...), this says the thing runs #Debian, and includes presumably-easy-to-use models for object recognition and such, and one of my high priority tech projects is a few cameras to notify us when the dogs are in places they should or should not be (backdoor = let them in, kitchen = get them out), and it's handling that dog recognition on local hardware that I'm still stumbling over.

Unrelated to this, I'm pissed off right now cause Nvidia has dropped support for the generation of video cards that is our newest model here, I have no idea if this means I'm not gonna be able to do any sort of Machine Learning or what, but it sure smacks of "we need to sell more cards and we don't care if yours still works well enough for you".

For those processing #Qualcomm pushing a new EULA that changes the #Arduino ecosystem into a thoroughly-slopped VC nightmare... I have had wonderful results from #Teensy devices:

https://www.pjrc.com/teensy/

Now, I have heretofore simply loaded the Arduino IDE and used Teensyduino to do the uploads, and clearly that is all over, because Arduino is over.

I wish I could believe that this will lead to people really thinking about the difference between #FreeSoftware and the corporate zombie thereof that is #OpenSource

You can trust the GPL. "Open Source" without the license is just Bait waiting for the signal to do the Switch.

does anyone know of a small (like a #teensy, or #seeed #xiao) cortex-m7 board? i have a teensy 4.1, but the lack of #JTAG/#SWD and direct access to the flash make it very clunky to work with. and no i don't want to solder mod the teensy to get access to the debug pins...

boosts in direction of embedded/hw communities much welcome.

Is the Teensy 4 still the speed queen of hobby micro controller boards? It's 7 years old (approx); shouldn't something faster have come out?

Teensy 4.1-based Programmable Guitar Pedal #TindieBlog #EffectsPedal #Guitar #Teensy #AudioProcessing
https://blog.tindie.com/2025/05/teensy-4-1-based-programmable-guitar-pedal/

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.
