Was able to etch a timer board, have to wait to etch the heater board as I do not have the correct size blank. Now for the fun part, scrounging up parts. Most parts can be had at Mouser or Digikey, but the Inductor, IGBT (or MOSFET) relays and high speed diodes will have to be purchased from overseas for the best price. A little eBayin and I will be able to collect them. For those who will build one of these, keep an eye out for old computer power supplies or junked out computers at the thrift. The power supply may have the appropriate inductor and some other parts that can be harvested and used in this circuit.
In all reality this project will probably run between $50 and $100. Depending on how many recycled parts can be found. Either way, something to build in your spare time.
