kevtris: hi
more sane ^
like 4V or something weak
not alot
how sad
omg .06 diodes
from vishay even
fuckit just do half wave
omg what fet
you can drive the led direct if its the only thing on the avr
i wish avrfreak would read avr datasheets
moon suggested a b output on the opto
ha yeh that too
i think some of the avr go down to 1.8V
so you could prob do it

lm337 array works
same brightness, 12, 24, 36v

apple product is so offensive

like instead of driving an inductive load, just driving an opto
the only weird non digikey part is the output transformer
and i can wind that

have to see about prices
but i can prob do that shit with 3904/3906
its like pulse power application
i think i might do thru hole as a DIY kit
so i can actually sell it
less i think
i can just use any opto fast enough then
load the opto for speed
i have to figure out the signal from the switcher
i kinda just wanna see if i can use any normal switcher for this

theyre fast
normal optos look pretty fuckin slow
i wanna try and do 100KHz
okay but you mean like a B amp with two BJT off a normal opto?
instead of the single switch and pulldown
anyway, im almostr done machining four 20 led arrays
then i gotta do 3 more

Posted by renesis at 05:34 | permalink | 0 comments

damn i frgot the emitter arrow on the collector

who is rchack ?
blackmoon: you awake?
ok that might be sane
there optoisolators for driving fet gates, not so much $, look good for >100KHz, might use one of those
