DocScrutinizer05on a unrelated sidenote: in Germany the soap manufacturer "Sagrotan" selling massively subsidized electronic soap dispensers that have a nice ultra-low power IR light barrier, a motor with attached liquid (soap) pump and other small goodies21:54
wpwrakso what kind of critters are you building with that ? sex toys ? :)21:55
DocScrutinizer05awesome feline starring: http://www.youtube.com/watch?v=ZAuMbdyJt2I22:07
DocScrutinizer05wpwrak: I actually pondered to exploit the sensor for completely different things22:14
DocScrutinizer05battery powered light barriers anywhere22:14
DocScrutinizer05this thing runs since 6 months from one set of AAA here (even with motor). Giving it a power driver for the IR-LED, a beefy IR LED and a reflector, you could build a sensor/alarm from CR2025, with a 866MHz transmitter, size of a matchbox22:16
DocScrutinizer05I'm also interested in the chip they use22:17
DocScrutinizer05of course you also could feed your hamster with a marginally modified such soap dispenser ;-D22:19
DocScrutinizer05basically I'm just amazed it manages to keep a light based active sensor running for months from battery, while it still has response times of <500ms22:20
DocScrutinizer05and that without ever (usually, at least for me) triggering false positives or false negatives22:21
DocScrutinizer05plus it's basically dirt cheap, since subsidized. which makes it worthwhile to buy one just for fun of disassembling22:22
DocScrutinizer05hell, it even comes "batteries included" ;-)22:23
DocScrutinizer05hmmmm, hotdogs, mustard ;-P22:29
wpwrak(hamster) if it likes the taste of soap :)22:58
DocScrutinizer51wpwrak: well, I guess a new device will maybe have even less pleasant taste23:34
