So Max the spider visited us in the lab today, and wanted to get into the halloween spirit. “I’d like to drop down on people in the elevator,” he smirked, in a way only a spider could. “I’ve got just the thing,” I winked, and put a little something together. You’re looking at a clear […]

I’ve been spending a lot of time thinking about op amps and comparators lately. One of the common uses of an op amp is as a “unity gain” buffer, meaning that the output voltage is as close as possible to being the same as the input voltage. At a glance this might seem like a

(See big LED version here) My nephews got a Scalextric slot car racing circuit from Santa for Christmas. This was a blast-from-the-past for my brother and me and we were soon showing the kids how to race. However it quickly became apparent that “3-2-1-Go” wasn’t the best way to start a race so I put

I recently had the urge to create some “eye candy”; Thinking along the lines of my LED Sign (it’s not dead, just waiting on parts!), I chose to create a similar effect, using only a single line of leds, instead of a 5×7 array. Persistence of Vision is some sort of effect, either psychological or
Minidot 2 – The holoclock Well maybe holoclock is a little bit inaccurate….it does use holographic dispersion film on the front to give a bit of depth. Basicaly this instructable is an update to my previous Minidot located here: http://www.instructables.com/id/EEGLXQCSKIEP2876EE/ and re-using a lot of code and circuitry from my Microdot located here: http://www.instructables.com/id/EWM2OIT78OERWHR38Z/ EagleCAD
