I play a lot of Starcraft 2, and I really liked the co-op mode and campaign. When Blizzard announced a map-making contest, I jumped at the chance to actually create something instead of playing all day.
Ever wanted to hold a contest but wanted to show that you weren’t playing favorites? Ever felt cheated at arcade games like the Tower of Power because you weren’t sure if they actually let you win? Those days are over.
Two years ago, before Lockitron and all of its competitors arrived, I went to college. During college, I created many prototypes of an electronic door lock that I detail below.
Lights are a necessity if you are going to be on the road at night. This applies to anything that moves–car, bike or pedestrian. I will document how I compared designs and settled on assembling a design based on Revolights for about $40/wheel. I call them SparkleLights.
In this video, I provide a complete tutorial on how to assemble your own stair lighting, featuring block diagram, code overview, testing and final layout. Code and schematic can be found on this page.
In this video, I show how I solved my hourly hydration problem by wiring a transistor to a water pump behind my desk. I describe three different ways of switching: MOSFETs, BJTs and relays. I then skim over logic gates and show how I added lighting to my bedroom.
