Peltier Coolers or Thermal Electric Coolers are used to make things hot or cold but have another cool use. Apply a heat source to one side and keep the other side cool and the Peltier generates electricity.

It’s true – I love DACs. There’s something awesome about the role they play, translating information from one paradigm over to another form. Sure, you can pick up a precision DAC chip with serial interface for a little over a buck, but building a barebones version from a handful of resistors is a pretty dang sweet trick. If you’ve never built one, I do recommend it. Doing so has a way of demystifying all sorts of related circuits and processes.

Equations for electronics math are available anywhere. If you have the excellent Maker’s Notebook, with its reference section and a calculator, you can plug in numbers and get answers to many of your circuitry questions. So why learn to do such estimates in your head? Because thinking through questions gives you an intuitive feel for them. It helps you quickly sort and refine ideas before committing physical resources to them.
