Build Your Own Specialty Power Supply

@ 2004/07/19
To start on the power supply, I sat down with a pencil and paper and thought out the process. Modifying the existing power supply would be relatively easy, and would involve more physical work than design.
However, the peltier power supply section would have to be designed from the ground up. However, our task is simplified in that a pelt is a solid state device, and does not need a sophisticated and perfectly clean voltage waveform in order to operate. Therefore, I decided upon a classic DC power supply that was based on an AC transformer with a rectifier bridge and capacitor for smoothing. Here’s the simple schematic...
