Default any help on revers engineer LED driver

ok ,

whom can revers engineer this driver for me?



reason why I want to stay whit this driver is because I’m not a electro tech, and when I can re build this driver I have something I can copy right on the table, as schematics dot tell me anything, for me it is more like: I need 1 of part A and put it there, I need 1 of part B and put it there

some info I already found (like the online resistor calculator) that explains how strong the resistor needs to be, and what a resistor is, but I’m missing some components I need to Know before I can build it.

I have 100 CREE led’s that I want to start putting together, I previously both this driver for $ 65, however in components it is only about $ 15 I think

so here we go:

A= negative from power supply (24V)
B= positive from power supply (24V) the bridge in between is in case I want to put a electronic dimming function on)
C= connections for a regular pot dimmer (that's on it now)
D= negative to LED
E= positive to LED

1= what the hack is this, and what douse it do
2= what is this ? is this the resistor (I found a online resistor calculator to find out what one I need) but is this the resistor yes / no) if no what is it and what douse it do !!
this one sits between the pin 2 from the driver chip and the negative

3= what is this one ? when locking with a magnifying glass it is printed don it T680 – what douse it do? ---- this one goes in the middle from pin 4 on the driver chip to the positive from the LED’s

*= 5 V DC voltage regulating chip 7805 CG
+= CAT 4101 led driver from onsemi
