I often have small numbers of PC boards left behind from earlier projects, because there was a fixed order quantity of 10 (which was still cost-effective). This page is a way to pass those extra boards – and the design ideas behind them – on to other experimenters who may find them useful.

Prices are minimal (largely overheads and postage) but support is minimal too – usually just a blog article here, with a circuit diagram and a parts list.

Most projects will involve SMD construction.

NB: I only offer the bare printed circuit boards!
Other components in the images on this site are for illustration only.

CAUTION: before ordering, check that your “24V” relays actually can hold-in at 12V!  Also allow some margin for supply voltage tolerances and the voltage drop across D2.
