Assembly Guide

An open-source hsoftware project.  For design files, source code, & additional 

documentation, please visit:  http://wiki.evilmadscience.com/Bulbdial

The  Bulbdial  Clock  kit  is  based  on  an  original  design  concept  by  David 

Friedman of IronicSans.com and developed at Evil Mad Scientist Laboratories.

The  Bulbdial  Clock  works  like  an  indoor  sundial.  Three  rings  of  LEDs  cast 

shadows of different lengths, forming three moving hands on the clock face.

This  guide  covers  the  procedures  for  assembling  the  Bulbdial  Clock  and  its 

accessories.  Please exercise appropriate safety practice while soldering.
