About a year ago I build this small device that could help me straighten recycled coil wire. Since then I recieved many questions regarding the construction of this device.
I noticed that most of the time a day, the sun was shining against part of the wall inside of my porch. And i was wondering if it is possible to use this energy to my advantage. I ordered some small solar panels at an online store. (18v, 140mA)
