Nove RGB LED v DX respektive levne IC pro menice?

[Jan Martincek]

Skuste RECOM drivre - tie sa daju riadit aj potenciometrom.
REC24-3.5 na 350mA by mal stacit. Ak chcete nieco stavat tak LM3404 cievka,
kondenzator dioda a par rezistorov.
Problem je iba odpor do spatnej vazby - tam to treba trosku popilkovat...
Ale ak mate cas nieje problem

Na DX se objevili nove 10W RGB LED s 50lm/W
http://www.dealextreme.com/details.dx/sku.44043

Docela bych z toho udelal osvetleni na schodiste, ale chtelo by to levne
menice.
Neobjevilo se neco z ceho by slo LEVNE postavit napetim (PWM,..) rizeny
menic DC/DC  24 / 0-1A (2A) ?
Preci jen RGB vyzaduje tri menice a pri uzasnych cenach spinanych menicu a
civek, v nasich krajich, to docela leze do penez.
