any help on revers engineer LED driver

[Bloodasp]

if you can provide a schematic i can figure it out.
1. is a capacitor. don't know the value though
2. is a resistor. not sure about value. i think it's 58 ohms can't really read clearly
3. it's just a jumper.

thanks for the info so far,

I dont have a schem.

1)the capasitor, is the value to be calculated, kind as uou calculate theresistor? this as I found a online calc. for LED resistors ?

2) if this is the resistor, it is printed on there T680 so would that be 68 ohms? ore with the online calculator I can calculate hat I need

3) as you mention, a jumper, dous this not matter what ore how much .... (in other words it would have bin a little cable to jump ?

the online calc. I mention is:

http://led.linear1.org/led.wiz

so supply with 24V
forward volt CREE = 3.4
forward curent 800
number of LED 7

answer would be 1 ohms right ?

there is an open source schematic on reef central for a diy driver. They even have the pcbs you can buy from an hobby printer out of china. check out the diy thread on RC - i beleive the dude who built it goes by van der wille or something like that

I know, proublem is there is so much info, you can read for years, and schematics dont tell me anything. I'm trying to educate myselve, but it is hard when it is something you never did.

while a coppy would be dummy proof I think, as long as I know what is what.

se all the treads and info you read is going so deep and complicated.

there should be a kind of stikky for a dIY driver that plain tells ok this driver is for ..... CREE LED's

part a is ...

part B is ....

and this is a step by step instruction.


now all thos treads go from something to something way way over bord, and you cant even find the basic anymore


I did mail Der Wilde, hoping he could help with a dummy prove driver
