Hmm, doesn't look like the internals of my old Aries, is this a true Aries or did you say Aries style to indicate its shape and size?

A resistor. A broken one at that. Looks like someone tried to jumper it across the solder pads, I'm betting it was either repaired, or someone tried to lower the resistance to get more output in the past.

R should be the decimal place in these resistors; 1R0 would be 1.0 ohm. R820 should be 0.82 ohm. (again reading the 'R' as a decimal place. 1R0 = 1.0 ohm, R820= .820, 820R would be 820.0 ohm, etc)

Best bet would be just getting SMT replacements though (R820, 1R0) and soldering them back on properly. They're not hard to get; they are a bit tricky to solder, and it looks like someone failed before.

1R0 is a 0-ohm resistor, essentially a jumper in itself, so you could take that red wire all the way to the solder pad and probably eliminate the 1R0 resistor completely. It -might- work.

No, wrong, 1R0 is 1.0 ohm resistor. 000 components are jumpers.

Since it is 1 ohm, replacing with 1.1 ohm has very little (but still has) chances of causing any kind of failure since we have no idea what the hell is it used for.

Great!
Power output?
Beam specs?

COLOR?! :crackup:

Where do you find broken lasers to repair, I want those too! I'm pretty handy... :D

Seriously, where and why did you pick those up?

originally 100mw 532nm

just put a 1watt 808 in there, need to realign the whole thing now so not sure on beam spec

just a friend ;)

ive got two of these :)

1W should give something like 200mW of green output IF alligned properly...

So a friend had two lasers that broke and sent them to you for repairs?
Damn! I wish I had friends buying bigass expensive lasers... :D
