Hi. I was struck by the fabulosity of your Fresnel Death Ray. However, since I am looking to make cookies outside of my house in the summer, it was a bit much for my purpose. Having made it, could you tell me if using several small Fresnel lenses might work too? I was hoping to get something less likely to blow over and that might be controlled easily with a Raspberry Pi (hopefully to be able to control the heat and not have to babysit it, having some simple gears to maneuver it as the son runs its course. If you wish to try this out I will buy the necessary Fresnel lenses and send them to you. Perhaps a simple dome of Fresnels over a clear hotbox? Or a big cast iron pot, heated by the Fresnels and insulated all around? It would be worth having. Thanks.

The Solar Death Ray is total overkill for baking. For that simple task, you can use a traditional solar oven, which is just an insulated box with a glass lid. They usually have reflectors around the outside. You COULD instead use a large fresnel lens to focus the light down to a smaller area into a solar oven, so that the lens would simply collect a larger area of light than the box alone would, but reflectors are smaller/simpler/more portable.

May I pick your brain? I have an electric pick up truck. the motor controller started smoking within the housing so I swapped it out, but on the same day before the swap the drive and reverse would not go into gear. Do you know if that symptom is tied in with the motor controller?The local mechanics are baffled and I don’t know where to take the truck to. Thank-you for your time! – Leona

I’ve heard that not all projector tvs have the right frenzel lens to best be set up and get the 2000 degree hotspot. Could you let me know what should be looking for?
