Its main chip is the ATtiny85-20SU, from the AVR/Arduino family. Other key parts include the MAX4392, LMH6643, 4053, Opamp_Dual_Generic and AnymaISP. By type, the board carries 105 resistors, 64 capacitors, 21 ICs, 16 connectors, 8 diodes and 6 transistors.

It belongs with the audio designs in this gallery.

From the project

Multichannel modular analog PAL video mixer based on the SYNKIE project

Multichannel modular analog PAL video mixer based on the SYNKIE project

The Anymix21 is a 12 channel analog video mixer based on the paradigm of classic audio mixing desks.

Each channel is a complete SYNKIE by itself, sort of. It can handle anything from DC to around 10Mhz, this means you can mix CV signals with audio with PAL composite video signals. Contrary to an audio mixer, inputs are DC coupled, with 0v being black and 0.7V white level. Negative levels are permitted but will be clipped at the final output stage.
