Dual Voltage (+/-) Power Supply Kit

We now have two dual-voltage power supply kits that are perfect for audio and op-amp circuits that require positive and negative voltage. There’s a bread board plug-in version and a case mountable version that comes with screws holes, standoffs and a panel mount power jack (designed for thevos synth line). Both + and – voltages are independently and finely adjustable.

CuriousInventor launched in late 2006 (pre-arduino era!) as a place to enable hobbyists, students, and musicians to create their own technology. We sold open-source kits and tools, and offered numerous guides & videos on things like soldering, metal working, screws, electronics, and more. 

The store is now mostly empty, but we’ve kept the product pages and guides up since they have useful information. Many of our guides and videos still rank on the first page of google searches and have been seen millions of times.
