Hi, I am trying to build a KOSMO variation of the nootropic audiohacker board. Now I would like some “additional eyes” from you to spot stupid mistakes before I design and order a pcb for it
My plan is to use it as a bitcrusher/sample rate reducer and also a freeze module, similar to the 2hp freeze Sam uses.
If you have other cool ideas what could be done with a 12bit ADC -> DAC Arduino, I would love to hear!
I added a TL072 to convert from ±5V to ±2.5V and then exchanged the original opamp for an MCP6004, where I add 1.25V to have a range of 0V to 5V for the ADC. For the output I convert 0V to 5V from DAC to 0V to 10V and then AC couple it to the output. The part for CV and pots is from Mutable Instruments’ grids.
It should be a 5cm KOSMO module in the end, it will be quite crowded! The jacksockets and the circle for the big button are just a reference and will be cut out later (will be connected via molex connectors).
This is just a first idea of how it could look:
