Velleman MiniKits MK111 Interval Timer

Ive used these for years as pulse signalling timers. Easy to build if experienced. This kits var res were not marked so needed my meter to work out which was which. The led also had equal legs so same again. The 555 also no notch but did have the dot. You may need help if inexperienced if your kit components come unmarked.

The product pack includes electronic parts to assemble by soldering. It is not a ready to use product as is shown in its photo.
