Guts under the platform
Initially I considered using a solar panel to power this tracker, but decided instead to use a rechargeable battery pack from an a portable vacuum cleaner that had a dead motor. I use a solar panel to charge the batteries when I'm not cooking.
Aside from a small tracker board and a motor I bought online, I already had most of the parts laying around. Total cost of this project was about $75.
The nice thing about it is that it takes less than a minute to get setup. Just flip the top platform over onto the lower, plug in the tracking head, and turn on the power switch. The whole unit is a little lighter than the Sun Oven itself and very sturdy.
I'm amazed at how accurately it tracks and it should make cooking in the sun a little more fun.
My next project is to build a robot that will put the food in the oven and then get it out when it's ready. It's on my honey-do list from the wife. ;)
