I think Brooks' design is worth studying. It is simple enough and uses 20 year old technology so even use old folks can follow how it works. Then you go off and build something else using current parts
I have one of those cheaper Rb units too. But you set them by sending a command over the serial port. Not by a control voltage. The DAC is internal to the unit. I plan to use a $5 TI Launch Pad. But basically the same over all ideas he used. At $5 each with shipping included TI is losing money. The device is self programming via a USB connection.
