Did you try flipping the batteries in the other direction? Or buying the plt5450b diode. It's a single mode 80mw inexpensive diode that has a nice beam and dot

Thank you, same to you and 🍺 to a new year with more laser technology for us to play with

That's an amazing shot! Happy new year to you buddy! And to everyone else I wish a nappy new year! Im learning so much more for this forum and its members about lasers so thank you all I'll be in your care for the next years to come Edit: I meant happy, not nappy lol

Way to save the day with the thermal shut down Paul, I don't like to think about what would have happened, had the laser not shut off and would have kept burning a hole longer also overheating the batteries and very likely would have thermal runaway and most likely no more laser but still just...

Safety glasses for the wavelength you are operating and properly rated for the power output of your laser should be at the top of your list. This is a fun hobby but it can easily leave you blind if you are not careful

Yeah that was the reason why I was using that driver, to minimize going over maximum current for the diode and I wanted to test fitting it in different hosts including the tool AAA and not risk an expensive diode also I came to know that the a140 and m140 are pretty rugged diodes. I event tried...

OK thank you I'll order the parts right now and I'll stop using the cheap driver. Although I do use much higher rated diodes for it. I was using that driver for some A140 diodes and they are still going without issues. It was more like a testing stage to see how to assemble and how it would fit...

This would be driver number 1 https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com/ulk/itm/112435751458 This is driver number 2 https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com/ulk/itm/113167178610 I have used a 405-450nm driver to power up a 505nm diode by accident and it...

Also be careful with those cheap green lasers that leak dangerous IR light that's not very visible but can cause damage. There was a post that had very useful information about it and if you have glasses that only protect your eyes from 532nm light and not IR light then you can see how it will...

Bienvenido paisano, welcome to LPF I'm a new member myself of Mexican origin residing in Los Angeles California . Soy del estado de hidalgo y si tienes preguntas yo podría ayudarte. If you have access to used/broken DVD burners that you can get for cheap than by all means harvest them and...

@GSS thanks for the tip about the better beam profile diode. I will try out your suggestion for the 450nm diode since I have plenty of A140 and M140 diodes I got for cheap. I was not specific in my comment but I was implying that I wanted to build a laser between 488nm-515nm somewhere in the...

Nice to know she loved your gift paul. Maybe you could help me? I gave the 505nm laser to a friend of mine last week because he knew how to appreciate it but did not have the skills to make one himself. Now I want to make one again but I'm not sure which diode is a good choice to start with

Merry Christmas to all and thank you for all the help. I wish you the best for this new year. May your pockets be deep with cash and your lasers bright

I have 3 working module swaps and I'm working on a 505nm diode and I wanted to try out a 638nm diode.. I need more of those cheap ebay drivers. I'll be making an order for some soon. This project got me more excited about lasers! 😎

Technically I am not machining or making anything. My tool AAA is a copper body. I'm just using the front part of a copper aixiz module with the diode pressed in and the driver soldered directly to the diode. The 12mm module fits inside flashlight head and is held down by the lip where the...

Yeah sorry, I might not be doing a good job at describing what I did lol. Im trying to say that I put together 3 different diodes in aixiz modules with their own driver and I can unscrew the head of the flashlight and pull out the diode with driver of the first "module" (diode pressed in to an...

Jayrob's builds are what inspired this mod. I saw how he got a keychain led light and squeezed the driver and diode inside with a few machined parts. What I did allows me to swap out from one "module" to another or put the led and driver back in the flashlight without having to do any mods to...

I have 3 "modules" that I can swap out of the flashlight host. I have a m140 diode in one doing about 1w battery life is less than 2 minutes and the host soaks up plenty of heat but still get hot enough to be a concern. I have a 405nm 5.6mm diode on the second doing 200-400mw not sure actual...

Yeah that's all too true. I wanted to test fit things around so I got a pair of cheap batteries for 5 dollars. I will be buying trusted batteries once I get my mod to work which is working fine but needs a few adjustments then I'll make a more detailed post if anyone is interested

The tab broke off the lithium pouch and only a small piece is left and it won't take up the solder the other one does so it's useless now. Yeah I haven't looked hard enough for reliable sellers for those batteries but the ones I got are working good enough for me, although I don't believe to be...
