We've been having fun playing with the L293D driver chip. It's one of those things to see how much you can make it do by itself (like with any BEAM application!). Grant McKee has been experimenting with some simple additions to the chip to make it (unto itself) a suitable brain for a simple mini-sumo […]
Escaps back in stock!
Dave Hrynkiw
June 17, 2003
Well, the last batch of Escap gearmotors went very fast. Let's hope this batch lasts a bit longer!
Unlike the last set, this set has a higher reduction ratio of 663:1 instead of 362:1. This means it starts turning 0.46V (!) drawing only 3.3mA (!!)
It's a 3V rated motor, but our tests show that they spin quite nicely at 5V, drawing 4.2mA free (!!!) at 22rpm. Don't know what the stall current draw is, as we're scared to strip these delicate gears, but it's greater than 150mA. Check them out!
