The problem with using Field Programmable Gate Arrays is that you have to learn a design language and then set up a fairly complex development environment to write programs in. That problem is addressed here.
This time, we'll build two projects. The first is a transformerless voltage doubler that takes a DC voltage from 12 to 30 volts and doubles it. Unlike most other voltage doubler circuits, this design can supply amps of current. The second project uses a power MOSFET in a linear (rather than switching) application.
In this final part, take a look at oscillator circuits that create their own signal during simulation.

Implementing a serial data link with the IR multi-board
This month, we're going to resolve the problem of the missing keypresses that we had last time with our SIRC system and then move on to accomplishing our final goal for the IR Multi-Board:
