Lunetta Lab 1.0

I know the title suggests that there will be another version of this and as I cannot deny that I would like to build at least some extension of this I’m pretty sure I won’t do it in the same format because the offboard wiring was extensive to say the least.

I didn’t lie, that is a horror
The board after the paint job and assembly
Here is the board before drilling. You can see all the ICs names on there as well as the (I) inputs, (O) outputs, (L) LEDs and (P) pots.

As the 4015 died on me I swapped it for a 4017. Now the layout obviously didn’t change.

Schematics

I did approximately three weeks of research before I decided on what ICs I want to use in which configuration and in the end I can tell you it’s not even remotely what I have imagined it to be. But nonetheless it’s a fun thing to play around with.

I was mostly inspired by stuff on electro-music.com and hackaday (logic noise)

I started in kicad but it was simply too much for me. Pls refer to the picture of the faceplate to check what goes where but I advice you to build your lunetta exactly the way you want it to be!!!
4 oscillators like this. Play with R1 and C1 values
Two wonky VCOs. I have to say I really am not sure they are that useful tho
The amp at the end to drive your headphones. Always check the output levels tho so you don’t pop them 😉

I know there are some pieces missing but you find everything you need to know here and in the datasheets of the ICs used/you wanna use.
