Renderer

Renderers are common notebooks with VGA→composite converter or lightweight devices with composite output (e.g. Raspberry Pi).

Video Mixer

Potbox

Generator

function:

  • program select (4 buttons + 2 digit display)
  • 4 pots - global setup (size, black level, white level, noise)
  • 4 pots - effect setup (see below for params)
# effect param A param B param C param D
00 lissajous curves a b delta -
01 grid - points density rotation rotation speed scatter
02 grid - lines density rotation rotation speed scatter
03 wireframe sphere rotation X rotation Y rotation speed X rotation speed Y
04 wireframe cube rotation X rotation Y rotation speed X rotation speed Y
05 shaded cube rotation X rotation Y rotation speed X rotation speed Y
06 circle thickness scatter - -
07 rectangle rotation rotation speed thickness scatter
08 circle+symbol rotation rotation speed circle thickness scatter
09 rectangle+symbol rotation rotation speed rect thickness scatter

Rupter

Converters

Some converters are needed for the whole solution to work. Especially VGA→composite (from notebook to Rupter) and composite→VGA (from Mixer to screen/output).

Monitor

We use the usual LCD screen (small are OK too).
