Failed at designing a Eurorack module.

I tried making a Eurorack mixer module since it's a module I still need and thought how hard can it be? It's essentially the hello world of modules and it failed.

I used different potis than I originally planned via the schematic and it seemed I can't get around ordering new ones since these ones were meant for a digital Arduino project anyway. So I'm not entirely sure what happened but I only get controllable hum and no volume control.

At least I tried but it seems Ive no luck with electronics. Digital Arduino stuff works fine at least.

Will see might get back at it again or order the correct parts maybe :P

Doepfer A-138n will take the open position

Proto pcb with the audi jacks hanging in thebair from testing together with a opamp and two potis.

Patch Arcana

I am just thrilled beyond belief to announce that, a full day ahead of schedule, I am releasing the newest version of the PETI firmware, version 0.5.0. This update, the Audio and Hygiene update, adds PWM-driven audio and the whole goofy poop mechanic to the game, as well as some minor QoL improvements.

Today my new #PCBs arrived. The first is an adaptation of Stefan Wagner's #C64 Power Guard: oshwlab.com/wagiminator/c64-po
I changed some components to what I had available. Thanks @aislerhq for manufacturing them.
Only I messed up two small details. The second #comparator is backwards, so the error #LED is practically the same as the power good LED. And I also put in the #MOSFET backwards. I'll try to mount it on its back and rotated tomorrow.

the empty PCBs for protecting my C64s
finished soldering all components. I didn't notice the errors, yet.

Finished #soldering. What I learned so far: l should clean between soldering #SMD components and #throughhole ones. I should leave enough space between the SMD components. I also dislike 0806 #resistors, better get some in 1206 size. The #capacitors were okay.
I tried it out with a square and a triangle wave as two inputs, connected through #potentiometers on a mini #breadboard and looked at the #oscilloscope
#diyelectronics #electronics #diysynth

finished board with all components soldered in. two inputs and the power are connected.

I need a single XOR gate. Should I:

1. Use CD4070 and ignore the other three gates? 40¢ in single quantities. SOIC-14 amount of space.

2. Build it out of transistors? 5-6 transistors, ~13¢/transistor in quantities of 10.

3. Something else?

Installed ironOS on my TS100 today. Very pleased so far. Just the improved menu and low battery warning alone would justify it.

I'm probably the last ts100 owner who has flashed it xD

Made a small stand from welding wire for it. One of those things that safe a lot of nerves when you are in the zone.

I also looked fo a small hot air rework station, a thing that I do miss and thats very nice for any smd stuff. (mandatory).

I will probably end up with a yihua 959d but I can't find the mk2 of it currently.

Tidied up my werkstatt a bit too.

Important preparacion for some funky electronics projects.

I tried out the automatic component placement function in Kicad yesterday, as I have a big (240x190mm) board I just started laying out. It works great! That is, if you want to simulate automatically ”placing” components by just dropping them onto the PCB.

I’m sure I’m doing something wrong, but it was pretty hilarious.

I've been on Mastodon for a while on a different instance for #activism and #anarchism related content, this is my "public" profile for my friends and fellow #lgbtqia from #brussels

I will not be posting much, and my content will most likely be about music and #dance #poledance but who knows 😸
