Electric Giraffe (2016)
I've been designing a very simple new circuit to control the servos in the forthcoming new neck. Each joint calls for a two channel servo driver, and I decided to add current sensing capability to this.
And so I want to thank everyone who’s ever turned a bolt, welded a piece, soldered a connection, or wrote code and designs for this machine, for getting “us” to the White House lawn, something I could have never imagined when I started this project in late 2004. In May 2014 I made my way, laptop in hand, to San Diego in order put the finishing touches on the Raffe’s software ready for the Bay Area Maker Faire. This is simply a 220 ohm resistor and a 100uF capacitor arranged so as to block any high frequency noise that may be present on the sensor, for example voltage spikes caused by the servo motor's operation.
