    488nm Diode Driver Questions

    Hello Paul, Long time no chat and thanks for the heads up. I appreciate the tip for 300mA. How much shift do you see here? I've always wanted to experience a "baby blue" beam. I have to rebuild my 520 soon also.. the adjustable blackbuck 8m in a maglite died somehow. I was able to dial it up...

    488nm Diode Driver Questions

    Hello everyone! Been a long time since I've built a laser or been around. I have mostly been building flashlights. Anyway I noticed the 488s have come down in price and decided to build one. The issue is a driver, and what current I can run. Will the 220mA from Survival work? What's the max...

    Newbie not getting full amps from driver with test load - SOLVED

    Are you feeding the driver with a 12v 1 amp capable power source? Otherwise if there's no pot to adjust I'd ask for a refund. The driver isn't setup properly.

    Hey Rich, If nobody else took this I think I will.

    BlackBuck 8M with 3.3v TTL signal

    Really? I am working on a Ortur Laser Master 2 for a client and it seems to only operate on 5V but I never read the signal from the controller. Now I will have to.

    Newbie not getting full amps from driver with test load - SOLVED

    He stated he doesn't have a 5V aux supply and wanted to use a phone charger with cut cables.. I told him it could work; but it won't be adjustable obviously. If this is a laser engraver there is likely only three pins on the input... TTL/PWM, Ground and +12V

    Newbie not getting full amps from driver with test load - SOLVED

    That's not gonna really give you any control over the output; it may be full power all the time. I guess you COULD try that, but the point would be to test the PWM and if it functions. Just make sure you check the output of the charger, sometimes they are 5.4v instead of 5.0v. The PWM on my last...

    The smallest boost drivers that I have ever seen! 5mm x 5.3mm

    Sounds good. Let me know when you are ready to sell then and I will still be testing some ;)

    How much is this one? Seems you been dealing with a loony here lately, cannot believe he complained over that. With the shortage of hosts and parts for DIY laser building, these guys.....

    BlackBuck 8M with 3.3v TTL signal

    There are many "industrial" grade logic level shifters out there on eBay, I have ordered several. It can convert the 3.3v to 5v with a small box, powered on the input voltage of 12-24v. Usually an input, and an output. They have them to convert to mA from mV and much more. It could be more...

    Possible alternative driver for Neje 30W module?

    Not sure if you've already tried this but make sure you do extensive testing and monitor the start-up current. There is a very good possibility this driver will over-current on start-up. I don't see much to the circuit in the way of 'soft-start' which is required for most all laser drivers...

    The smallest boost drivers that I have ever seen! 5mm x 5.3mm

    I actually pulled out my "toaster oven reflow station" today and started making a batch of LED drivers. I too built some buck/boost drivers back in the day and had some guys on here testing for me with 450nm diodes. I would be interested to test if you need someone to. I have Oscilloscopes, lab...

    Newbie not getting full amps from driver with test load - SOLVED

    Are you sharing Grounds between the PWM signal source and the driver? If not, this will cause issues. I have seen some of these cheap drivers require more voltage than 5V to get max output. I would do like myself and use a separate adjustable 5V power source to simulate the output and see if it...

    Hello All! Been awhile.

    Hey paul thanks for the outlook and info on the 488. I have had many 450s and a few 473. I really want to experience a 488 atleast for little while. What's the max current you guys run those 488? And the minimum output for less shift and still decent beam.

    Hello All! Been awhile.

    Thanks buddy! It certainly does man, sometime it's hard to find spare time for hobbies. I have been looking on the website for 488nm beam shots. Any suggestions for a driver for the 488nm?

    Hello All! Been awhile.

    Hello guys, Been quite awhile since I have logged on. Life has been crazy lately with the new house and my kid about to start school. Just the other night me and my son pulled out some of the lasers and had some fun with them. Also we have been using those star shower motion things to have some...

    Best "High quality" 532nm Pen in 2018?

    5mW is a plus of course but not to worried about IR unless its an unreal amount. Even if its a little over 5mw i wouldnt worry; but I didn't really want to get the regular old pen host, I wanted something a little more "executive pen" style. /edit: I do like the ll 520 though.

    Best "High quality" 532nm Pen in 2018?

    Hey all, been awhile and i apologize I have fallen off so much. I still use my lasers quite regularly but my work schedule has been crazy since i changed shifts. Anyway, I killed my Hugsby XP red pocket build and wantes to replace it temporarily with an executive style 532nm pointer for...

    4 host for sale

    I would be interested in one of those hosts also, if there are any copper available still; otherwise an aluminum; and maybe the heatsinks/focus adapters. As well as the round x-drive!

    Hello old friend! I really like that 501b, it looks like one I have seen from you before with the camo. Now you are adding the BE? PM me about it.
