New server, new #introduction -- I'm still the same old calcifer or cal from hackers.town, but the castle has been rebuilt
Old nerd with a passion for resiliency and software/hardware in constrained environments (like #arduino, #esp32, and similar embedded systems). Also #queer, #polyamorous, and #autistic #dad
No patience for authoritarians, bigots, or bootlickers. Rights are for all people.
Why, in this day and age, do I need to tell the compiler exactly what type each variable is?
Or am I just lazy after too much Python and Matlab?
NEW INTRODUCTION! After 3 years, some of my interests pivoted and some are just not on fedi.
I'm a one man company that mostly does 2D computer animation but I also do interactive writing and co-creating the first ever video game completely about larp!

Ok, I'm going to try an experiment. I usually don't post a lot, mainly because I wonder if people really care what I think, think about or do, but perhaps that's just #AutisticMasking. So for the next few days (I'm just starting my long weekend), I'm going to try to break out of that, and try posting about most things I'm doing and thinking.
Fair warning: if you usually find me boring, annoying or irrelevant, you might want to mute me now...
We'll see how it goes - how I feel about it and how exhausting or otherwise. I'll try to post about that too.

happy to see renewed interest in arduino-cli-mode for #Emacs, which i maintain :) today it becomes an even better #Arduino IDE alternative, thanks to zck who added serial monitor support! it auto-closes/restarts when uploading code.
now who wants to do a serial plotter?

Oh wow, the #FreeBSD #Linuxulator is just magic! I setup an Ubuntu #LinuxJail as described in the linked wiki and was able to compile and flash #Arduino code to my Uno using #PlatformIO, which is absolutely mind blowing because the tools for compiling are not available for "freebsd_amd64", yet in this Linux environment (not emulated, not a VM, just a translation layer), the Linux binaries were able to compile and then flash to the USB device (using the FreeBSD kernel… https://tobykurien.com/post-1744211915
I built a latency meter with an Arduino and a photo transistor to answer one question: Is click-to-photon latency higher on Wayland than on X11?
And the answer is: Yes, actually.
42 ms on X11, compositing off 56 ms on X11, compositing on 64 ms on Wayland 71 ms on Windows 10
Tested with Plasma 6.3.4 and Firefox 137. I will improve my methods and confirm these numbers. See replies for details.
First trial run when all the components are in place. The program listens to the four inputs the pin operates the real heads with and simulates centering the eyes and behavior of the eyelids with their latch+release mechanism.
To-do: automatic eye blinking that's better what the pin can do and the small eye movement when the eyes are idle. Probably adjustment for the eye movement speed too, right now it goes as fast as the servos can do.
Part 3 of building the DIY seismograph. So continuing on the moving arm concept, I settled on using a servo motor as this could easily be driven by the Arduino. I had to make the arm very light so as not to put too much pressure on the small servo motor I was going to use. Here is the model of the arm. Although I went back and forth with different ends to hold the pen, ultimately I ended up going with this clip. Modeled in #freecad #maker #diy #earthquake #arduino #servomotor #seismograph

Forgot your safe combination? This #Arduino-controlled autodialer can crack it for you - https://blog.arduino.cc/2025/04/01/forgot-your-safe-combination-this-arduino-controlled-autodialer-can-crack-it-for-you/ "design quirks tend to eliminate specific number ranges and can help the cracker find one or two dials through feel alone before moving to brute-forcing."
Minimalist, Lo-Fi, programmatic minimalism.
I've implemented a Lo-Fi Orchestra, Arduino version of an extract of Philip Glass' Einstein on the Beach. More specifically, part of Knee Play 1.
In this version the HT16K33 is performing the voice number parts alongside a synthesizer for organ and voice sounds.

Sketch for a kinetic sound sculpture made @soundartlab_dk using found materials around Struer: A bin (cut up and used as an arm), sheets of rock found at the local beach, scrap metals and a cymbal.
Thanks to Sound Art Lab.
