I have no pecuniary interest here but I like scopeclocks and the kits were discontinued for a while. Unlike the Sparkfun SMD pre-assembled board that was based on these, this is the original type through-hole kit and improved over the previous version and from the original person. This is the original Dutchtronix scopeclock.
All you need is this and an old scope. (and some time and solder)From: jdr at Dutchtronix
