im soldering up led arrays now
i made little boards with 20 leds in two strings

kevtris: hi
yeh?

more sane ^
um
like 4V or something weak
yeh
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
oh
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

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

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
yeh
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
Posted by renesis at 08:55 | permalink | 0 comments
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

blackmoon: im prob going to use a gate driver opto
what else do i need to change?

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
