Learn Electronics the DIY Way!

Circuit Specialists is proud to announce our new line of Educational Project Kits as well as the Southern Cross Single Board Computer System. These products are from D.I.Y. Electronics & have been successfully sold throughout Australia & Asia for many years.

These kit designs are fully tested & guaranteed to work! They are designed to provide educational value as each kit includes complete documentation, a schematic diagram and a short discussion on the theory. All of the circuit boards are made from 1.6mm fiberglass. They have been silk-screened on the top to aid in component placement and the backs have been soldermasked to aid in soldering. The solder pads and traces are on the large side to help withstand rough handling.
