Digitaler Fahrrad-Tacho (Reed Kontakte)

This edition of Summer Circuits differs from our traditional double issue since almost all of the contents are entries to our competition. The response to the competition was outstanding with over 3000 circuits ..,. and design ideas submitted from all corners of the world (and beyond). In practical terms, this is about two miles of paper and presented our staff with an enormous task in sorting and evaluating the various merits of each individual entry.
