This is the ec500 error.core ONLY. You will most likely need the following accessories for this to be useful to you:
The error.core is the hub of the ec500 system – it takes 12V DC power, regulates it down to 5VDC, and provides an expansion bus that delivers power and hsync/vsync to expansion modules. It also has the connector where various interfaces – currently just VGA, others TBD – attach.
It has 9 oscillators, all of them square-wave. 6 are simple, not voltage-controllable, and provided by a single 40106 IC. 2 of them are provided by a 556 timer IC, and are voltage controllable with variable pulse-width. 1 is provided by the VCO in a 4046 PLL chip, which also provides a phase-comparison circuit. All of the oscillators are syncable, and 8 have switchable capacitors for speed control.
Beyond that, there are three mix busses (R, G, B), as well as switches to control whether RGB signals are passed thru from whatever external source is connected.
