UPDATE 3/20/2020: I have moved the old V1.5 Arduino shield based version to a separate page. Much of this projects history is there, so if you’re interested in what this whole DG5 emulator thing is all about, where it came from, what it does, etc., then read the original page above.
I have 2 versions of PCB’s available for purchase, the V1.5 PCB is an Arduino shield. Please note that the RCA jacks on that board are no longer available, but if you’re planning on wiring in jumpers to RCA jack in a chassis, it doesn’t really matter. Secondly, you really need an Arduino Duemilanove or similar – you want a proper crystal running the board, not a ceramic resonator that the later boards (UNO and others) comes with. There are some options, like the Freeduino Eleven, but I decided it was time to incorporate the Atmel 328P micro-controller on board, and to update the RCA jacks, so V2 was born!
The DG5 Version 2.0.3 PCB is basically the same circuit, but incorporates the Atmel 328P. Because of this, you need a way to program the chip – buying a blank one from Mouser won’t work unless you have the tools to program it. You could buy an Uno, program the chip, pop it out and put it in this board. Or, you can buy a kit with the chip pre-programmed.
Be sure to go thru the DG5V2 build instructions
4/25/20 – I have removed the purchasing options for now, I am currently selling the LED kits on eBay which will hopefully simplify international shipping.
