It feels like all my peers are experiencing Deep Blue and having to choose their future career path:

expert in a dying field

or

collaborator in a fascist project.

New year, new keytar thread.

Here's my power hungry charlieplexed LED board. It will serve as both indicators for various MIDI controls, as well as a low-res display of sorts.

The top row are faders: 9 for organ drawbar stuff, and the last 2 for expression and main volume. The group of 16 LEDs at the button left are assignable toggle buttons. The weird thing in the middle, with 6 rows, acts as virtual guitar strings for the strum section. The big LED matrix at the bottom right is either an XY pad or palm mute depending on the mode your in. And the row of 6 LEDs directly above the XY pad is pitch bend.

Hopefully, I'll have the CAD model soon showing how this fits in with the touch panel.

An old M28 series locomotive, first produced in 1955 by the Hungarian Wagon and Machine Works in Győr. Mostly they serviced industrial railways, moving loads and freight.

This one worked at a now abandoned thermal power plant in Hungary. Now it sits silent and forgotten inside an old rail shed.

After having to low cut the master at our dub / kraut rehearsals I'm seriously considering getting into sound system making. (The smell of burning woofers is no fun).

This is the worst possible video to see in that situation. (And you should absolutely watch it).

I'm designing an ADSR circuit where I use a schmitt trigger to store the state of the envelope and figuring out the resistor values to get the threshold voltages I wanted was a bit slow, so I made this little tool for playing around with them: https://tools.sandelinos.me/opamp-schmitt-trigger-playground

Just put in the output saturation voltages of your opamp and mess around with the resistor values (the arrow buttons jump through E12 standard values) until you get thresholds that you like.

#Samsung devices from today can no longer install custom ROMs.

Odin is gone and the Download Mode is also gone, which makes life hard also for repair services that want to restore a device.

This is your daily reminder that #Android is a liability, and major hardware manufacturers who ship Google’s version of Android are a liability too.

We need to get Linux phones to work, and we need manufacturers who are aligned with our principles.

TODAY 7PM - Show and Tell (our first)

An opportunity to show off what you have been working on, seeing what other people have been working on, and maybe find a collaborator for your next project!

Format: 5 minute lightning talks to explain what you have done, what worked, what didn't, and what's next.

Projects, projects in progress, and hoped for projects of all kinds are all welcome. Show off your textiles, code, electronics, woodworking projects, and anything else you are excited about.
