I presume that you're holding your feelings back a little !!!

If the Peltier outputs 5,420 volts, You may have a free energy machine !! Also, For the hot side of the Peltier, you might consider a flat black engine paint -- a light coat. If you burn it, clean and recoat.

The beam coming from the fiber is still quite divergent but I have been able to burn black paper at about 2 feet. It appears to be a 1/4 " red dot with a hot spot in the center. I think I need to pull that line of 19 dots into a point.

I found a 7" fiber cable with correct fittings for the FAP module. Instead of transmitting the 19 dot format, this appears to homogenize the beam into a small bright dot. I'm playing with lenses to try for a better beam.

I agree. Should I get a PCX or a PCC and use a PCX as an expander ? Also, I see these "laser cannons using what appears to be a projector assembly. I have tried a CCTV lens and can only focus to about 2".

I have a MAX 130 and I discovered how to get the fiber to work. I sheared the fiber with a sharp scissors then stripped off about 3/4" of jacket. I porered it up with about 2 amps and set fire to the casing. After blowing that out at about 1/2", I cleaned the area with pure alcohol. NOW, when...

Have a garden hose ready in case you ignite that nest under the soffit.

Where did you find the lenses? Which one works ? Mike

I am currently experimenting with a PS like the one you show on the left. I need 15 v @ 15 A for my MAX 130. I've read that running two of these in parallel is not recommended. Mike

I removed the fiber cable from the housing and found a hole about .4" deep going toward the PCX OC lens inside. The hole is .098" diameter ending with a small hole (~.05") in front of the OC. I placed an old photo negative in front of the module and gave it about a one second shot at 30...

I'll try that. I have an old night vision scope. Once I remove the fiber mounting, Can it be remounted with little to no alignment? I read here that one guy had to drill the opening wider to accept a lens of some type. I already bubbled a small glass laser lens !!!!

I just finished a 405 "pointer" which is about 3"long x ~1/2 " Dia. It will hit 417 mW for a few seconds! A aaa Li cell gets hit hard. Focuses to a tiny dot. I'm back to my 915 Nm module now. I don't care for fiber. Mike

I've started working on my MAX 140 again. I've found a way to get the fiber to work well but I really want to go fiberless. If I remove the fiber fitting, Does anyone know how much the beam diverges ( beam Dia) at the edge of the module. I'm running the module at 5 Amps. Max is 15 Amps...

Thank you -- I need to do some research. I'm only finding completed lasers. Mike

I have had the top off and yes, it's full of mirrors but no targeting laser. I need to know how big a hole has to be drilled into the housing where the fiber exited. How large is the first lens you used to grab that expanding beam? Were you able to focus it? The two lenses between the lasers...
