First Working prototypes

Self-etched "Made in Taiwan"

Tokyo hand-solderer Prototype

See our first working prototype in the video: https://www.youtube.com/watch?v=9HnzJeK31R8

Working prototype_taipei

Background

Inspired by the bootloader for atmega by Christoph Haberer and other implementations by Fredrik...

Not found anything yet for attiny, except that's it's a bit more challenging to make bootloaders.

Can we maybe use the same bootloader to program via blinking lights?

Bootloader developed and works fine

see devel repo here:

Boards are being designed atm...

Test your prototype

Notes from our first testing phase: https://github.com/8BitMixtape/8Bit-Mixtape-NEO/wiki/3_5-Testing-the-prototypes

Version 1.0

Older versions

See wiki: https://github.com/8BitMixtape/8Bit-Mixtape-NEO/wiki/3_2-Schematics-Discussion

Basic stuff we have

  • 2 potentiometers
  • 2 push-buttons
  • 1 Sound output PWM (PB1 is preferred) is also CV output in case of Sequencer code
  • Sound-progger input
  • CV input (maybe 2 CV input
  • Master-clock or gate output
  • Sync-clock input (compatible to other voltages
  • 1 pin to communicate wiht the 8 NEO-pixels (is that cheating?)
  • what else?
  • mic-4 ring jacks?

The Beginning...
