@Max: I smell a blog in the air... Well if I get the time temperature profile wrong, the smell could be burning chips and resistors. I think a blog could be in the offing for the oven.As long as I can get the other blogs out the pipe line not all EE-Times.
There have been at least three projects on Kickstarter using this type of approach, two were funded one not.
Do not think PWM is needed as the thermal lag calls only for a variable on off time to the heaters.
Just waiting for the thermocouple Amps to be delivered and then I can get the oven from the white goods outlet ARGOS, I think £80 all in should see the job done.
@TonyTib: Can I persuade you to upload a photo to your profile -- I see so many of your posts -- it would be great to see who I'm talking to -- if not a photo then at least a graphic icon you feel represents your personality :-)
@TonyTib: Giving the massive number of Kickstarter projects, I think you really have to spend a lot of time promoting your project. Good luck next time, Max!
I think our problem was that we aimed high for the number to sell so as to bring the board prices down -- but the boards are not actually the most expensive item (just the ones we could control) -- it's the cost of the connectors that killed us.
We are currently talking about relaunching the project with a much lower goal and a different pricing model.
