[QUOTE="kc0pph, post: 980729, member: 35934"] I have had some interest in a controller and if i can get a few people to buy one to cover the costs ill develop it up. Fixed costs for 10 Printed Circuit Boards to be made (china special) is about $60 and then the parts are in addition I would prefer to use a solid state relay due to the high amount of turn on and off cycles (although most ovens use standard relays) This will be a major cost in the production at $33 each. The rest of the components can be bought for around $10 so cost to me to build would be close to $90. After that its just the approx $43 per unit. If we can get some people that are interested in buying these then the per unit cost would be around $70 shipped. Little note: I can not sell you a completed project as it has to go through UL first so to bypass the EXTREME cost of that I will provide a controller board with terminals and the solid state relay. You would then have to wire in your own heating element (if it is a 230V heating element as the initial spec will be 2300 Watt element or 1150 watt for 110V) and run wires from the board to the relay. In addition if you want a fan you will have to use a DC fan and run wires from it to the fan. The Printed Circuit board will come with standoff's that you can mount anywhere you want and you will need to supply a wall wart to power the board (If you will be using a 12V fan it would need to supply enough current for the fan plus about .2A for the controller and powering the relay. As for controls someone more knowledgeable than i needs to chime in and say exactly what the process is. As i understand it heat to a low temp to vapor off any residual cleaning agents, spray and bake at 180F for a period of time. I also understand plastics have a different process. The user controls can be a knob that adjusts temp (say 1F increments from 100-500) and maybe a selector for different thermal profiles. [/QUOTE]
