New in the Maker Shed: Bulbdial Clock kit


The Bulbdial Clock kit works like an indoor sundial, but with three shadows of different length. You tell the time just like you do on a normal clock, by reading the positions of the hour, minute, and second hands.

This clock kit comes complete with three custom circuit boards, 72 ultrabright LEDs, pre-programmed ATmega168 microcontroller with Arduino bootloader, tactile button switches, aluminum standoffs, 20 ppm quartz crystal, custom clock face, gnomon spike, universal-input plug-in power supply, stainless mounting hardware, plus the resistors, capacitors and other little parts needed to build the Bulbdial clock. We even included a laser-cut acrylic case!

Bulbdial Clock kit in the Maker Shed


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 .
