Not sure yet, as of right now my Ophir, but I may use one of my school's LPM's if I feel the need.

Thanks for the compliments everyone :D I do still have some tiding up to do, something like a headphone jack connector for the head is probably a good idea. I am finding the acrylic to be very fragile, probably going to have a custom design that is more durable. Also a question, What style of...

Forgot about this thread, Here is what I ended up doing, probably not the "right way" of doing it, but it worked... I endned up drawing a circle and making it thick, But when connecting the + and - pins, it didn't pick up the thick circle as a pad, so I just randomly put a pad under the circle...

I present my new and improved LPM design: (Now a Release Candidate):san: LPM is powered by a 3.3v LDO, So no crappy 9v batteries, and no boosting regulator in this LPM :D The ADC and LDO are High quality, High accuracy, and Low noise. made by Texas Instruments ;) The LPM is also very...

Re: 2W Small Sun - Stainless Steel 445 Laser Price lowered to 230

SOLD! Nice little 2W laser in a Small Sun host Runs on 2 IMR 18350's (included) Universal charger and safety glasses are also included Recommended duty cyce is 30on/30off M140 Diode G2 lens 1.8A Driver Gold plated copper Heatsink Copper aixiz module 230$ shipped to the USA

I didn't have any trouble with the inner ring, But I cant figure out how to make a hollow pad Also if there is a standard size for the + and - pad that would be good to know.

Just a thought, You could ask Moh if he is willing to give you the Eagle files for these, since he doesn't make them anymore he might. For small quantities, you could get them from OSHpark for 0.70 each

That sounds wierd, wouldnt the duty cycle be 66% regardless of what mode you are in? On for 1/3 blue, on for 1/3 green, and off for 1/3 red? I guess it isn't that simple... I did see the peak current for an A140 was 1.44A in a thread on PL, but they didnt say what the duty cycle was

Re: Mohgasm 1.8A, 1.63A; $10 Each The 1.8A ones have 2R2 instead of 3R3

They are broadband coated, The 1064 is just where they are most accurate.

EDIT EDIT: Currently I'm too busy with school to do this, At some point in the future I will start selling LPM's NEW OFFER: Anyone who buys this kit from me can mail me there finished LPM un-calibrated, and I will calibrate it with a 1.5W 445nm blue laser at 25c against my ophir head Free...

The 20c-a is rated for 4W's without a heatsink. Theoretically the resolution is 5W / [2^(10+5)] = 0.15mW but I have it truncated to 1mW resolution

750mA sounds reasonable, The A140 and M140 are both 2500 lumens right? and they both have 24 diodes right? So would that mean that the m140's have to be ran at a lower current? or mabye they are over spec...

Does anyone know what current these diodes run at in the projector?

Can be powered from a 9V battery, Lithium-Ion Battery, Or wall jack. Switch on top connects the battery, Wall jack always powers the device on. Has a 10 turn pot for precision Zero'ing... Actually because it fit better than a regular potentiometer ;) Please excuse the theme song :p I made...

Re: Mohgasm 1.8A, 1.63A; $10 Each Still Available

I could build a few of these, they would cost about $200 each Other than the first one that sells, it will take a while to make them. Because I will have to order some more PCB's off of OSHPark Also, I haven't made a datalogging program, Mine works with Eagle eye, if you don't have access to...
