Build it pages


Click Here to load this page into my sites frames
(you are missing out if you are not in my frames !)


These pages contain electronic circuits that can be built onto a piece of perfboard.

If you build any of these circuits, all that I ask in return is that you click on the link to support my site (below)

Some of these items can be a little tricky to build.


Everything listed is built at your own risk,
I am not responsible if you damage your equipment.


I built some of these circuits, so I know that they work correctly,
(with the exception of the circuits that have been sent to me, I have not tested them)
