The kits use “denshi blocks” (also known as electronic blocks) to allow electronics experiments to be performed easily and safely. More than 25 years after its original release, one of the main kits from the series was reissued in Japan in 2002 and now you can get it here!

The Maker Shed is brought to you by Maker Media, the makers of MAKE Magazine, the Maker Faire, and much more.

Launched originally as a source for back issues of MAKE Magazine, the Maker Shed expanded rapidly to meet the demand for 'projects in a box,' otherwise known as kits. Now we have a little bit of everything for makers, crafters, and budding scientists, from Arduinos to sock monkeys to chemistry sets .
