yeah ur right. i just added a 1.5v AA to the 2x cr123a's and viola, it brighter and burns stuff and this is at 300mA's now i must make 1A :)

does anyone know how much power output i would get from 300mA of current to the A-140 diode with a ts317 voltage regulator with 2x cr123a batteries 3v each.. it doesnt seem to burn anything.

okay, ive found out that my batteries are dead. i charged them overnight. one is 0.00v and the other is 0.36v....that has got to be the problem.. but il see what jib has to say about the driver i sent him.

okay nvm about the mah, i need this to be solved, i made a custom build lm317 constant voltage driver. @ 300mA and the diode did not lase. the diode must be broken.

no GTL lr123a

@ rocket689 yes ive sent him the driver back to get it tested. but its been 5 days so i havent heard anything yet. it normaly takes a week or so for delivery time. and yeah, my batteries where full. but then it got flat quite fast. however i just remembered that before connecting my batteries i...

protection against shorting. and what do you mean dont let the battery over discharge? i hadnt mentioned anything about discharging the batteries.

okay. so a few weeks ago i built my first ever 445 laser. or should i say. my first EVER laser build. :D. i was using A-140 LD, Jib's lm1117 driver and 2x GTL brand LR123A batteries. (same size as CR123A). i set up everything by using bhwollen's hotlight tutorial, since ive got a blue hotlight...

Re: FS: LM1117 Linear Driver - 1.3A Fixed ok, ive sent out the diver yesterday, you should receive them within a week or so. let me know if they are faulty or not :)

Re: FS: LM1117 Linear Driver - 1.3A Fixed ok il send it off first thing tomorrow.

Re: FS: LM1117 Linear Driver - 1.3A Fixed wait, i think i found out the problem. i just built a dummy load. and hooked it all up. and my driver doesnt even heat up...i think the driver may have been damaged. when i did my laser i didnt secure the connections with heatshrink. maybe i shortened...

Re: FS: LM1117 Linear Driver - 1.3A Fixed aw man i didnt discharge my caps....maybe thats why its broken..when i first turned it on. the laser was dim..and then it got instensly bright and hit myself in the eye...luckyly it was way out of focus and all that happend was it made my left eyes see...

Re: FS: Blue Hotlight Kit ahh cool :) i was gonna say dont bother i could knurl it in school. but if you bought the straight knurling tool then its good :D

Re: FS: Blue Hotlight Kit hey Moh, if its possible would you be able to knurl them too :D makes it feel nice lol and how much are they gonna cost?

Re: FS: LM1117 Linear Driver - 1.3A Fixed hmm okay. i will build a test load tomorrow and try and see what the problem is. thanks for the help guys. :) also. i dont have a DMM but i tested my batteries buy shortening each one out...first one. heated up almost un touchable..thats normal. becuase...

Re: FS: LM1117 Linear Driver - 1.3A Fixed hmm. ive got no money left. but how much do you sell them for? il take it into consideration :D

Re: FS: LM1117 Linear Driver - 1.3A Fixed ahh u typed that while i was typing this lol okay :P

Re: FS: LM1117 Linear Driver - 1.3A Fixed help please lol im dying to use the laser but i cant. tomorrow im going to use the schools DMM to test batteries. but how can i test the driver to see if its outputting any current? would i just use a DMM for that also, if so...which parts do i put the...

Re: FS: LM1117 Linear Driver - 1.3A Fixed hmm i dont have any tools for measuring current etc. what things do i exactly need to measure output current etc. and what can i use as a dummy load?

Re: FS: LM1117 Linear Driver - 1.3A Fixed hmm i think the batteries are fine but i only built it today :S could it be the driver? i may have shortened out something maybe thats caused it? im pretty sure the diode is fine.. is there any way i can test to see if the component are working or not?
