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

Background

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

• http://www.fredrikolofsson.com/f0blog/?q=node%2F596

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:

• Iyoks devel: https://github.com/ATtinyTeenageRiot/TinyAudioBoot
• forked and improved by Chris: https://github.com/ChrisMicro/TinyAudioBoot
• find all files, pre-compiled and examples by Chris: https://github.com/ChrisMicro/AttinySound

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...

Late night geeking at Iyok's ego-lab...

After years of geeking around wiht all these versions of 8bit Mixtapes...
