Ah oceansoul, that's just what I need. Thanks for the link. At least now I will have a better understanding of how to build, test and run a 'propper' laser. Thanks again

Blue led. Thanks for the very funny annecdote. A lot can be taken out of that experiance. Bionic, I understand what you mean about breadboards. I did build my driver on strip board though. Your idea of keeping it shorted is something I did not think about. I will keep it in mind. Thanks for...

You are correct on one of those two points. I did not have a heatsink however I do have a multimeter and I did check the current readout, although only after the suggestions made by Blord. That said, I didn't have the driver pot turned up all the way when I switched the power on and the laser...

Oh dear. That's what I was affraid of. Looks like I'll be getting another diode then. Thanks for all your help with this thread Best wishes

Hi. Just a quick update. I have put three 10r resistors in parallel (3.3 ohms by my calculations) but my diode is still no where near as bright as I expected. I am beginning to wonder if I have damaged the diode when soldering the leads on. This is not to say that this is my first time soldering...

Yeah I wondered about a heatsink. My diode does get very hot. I will get both 1/2 watt and 1 watt resistors and look into getting a heatsink. Once again, thanks for your advice. Best wishes

Ah that explains it. I have a 100r pot in series with two 10r resistors. I will aquire a more suitable resistor as you suggested. Many thanks for your help, Kind regards

Hi. I am running it off the DDL driver from 'it can be done laser driver'. Not sure what current it is at. I have the pot turned all the way up but the laser is still only barely visible in pitch black. Kind regards

Hi again. I have just fitted my LPC-826 red diode into a focusing lens and housing that arrived this morning but the dot is no where near as bright as my >5mw red diode I had before. I am running it through a driver off a 9v battery. Can anyone tell me how to increase the brightness? Many...

Hi. Thanks for your reply. I have ordered a housing and lens and look forward to its arrival. Many thanks again Kind regards

Hi. I started a thread a while back about red laser diode intensity and got some great advice. I then bought an LPC-826 diode and built a driver board as suggested. My question is, I have never constructed, so to speak, a laser. My diode doesn't produce a dot or beam so I assume I need a housing...

Oceansoul, I thank you for your thesis on LD's and drivers. It did make sense. Unfortunately I don't have a smoke machine...yet. I am looking into getting one. It isn't for any type of production. Just a private prop reproduction. I am very much up for making the driver myself. I have been...

Thanks for the link. I will take a look at that shortly. I would prefer not to have to depend on smoke to see the beam but if all else fails then I will stick with my 5mW LD and get a fog machine. I will definitely be getting goggles, I think they look cool no mater what. Plus they save your...

Ah, fretwrecker94, I was aware I might need a driver but wasn't sure how to go about getting one. Am I right in thinking I can build one? Your advice would be greatly appreciated thanks. Oceansoul, strangely enough I was playing around with smoke with my little 5mW LD and it looked great. I...

Midias, that's fantastic. Just what i need, thanks. Can't wait to receive it now. Thank you to all for a pleasant first experience on your forum. Kind regards

Hi, Thanks for all your replies. Lase, the laser really does need to be red. I am building a prop replica of a Star Trek Boomerang phaser and the beam is orange. Now as orange LD's are WAY more than my budget, I decided to go for red. Soren, thanks for the advice. I will look into getting a dvd...

Thanks for your reply. Sorry, I need a red laser for my project. Preferably, I would only want to spend around £10-£15 but if I can't get anything decent for that amount, then I will stick to my current 5mW diode. With regards to visibility, I would like to be able to see the beam fairly well...

Hi, I'm quite new to lasers and therefore need your help. I want to buy an inexpensive diode that produces a visible beam. I was wondering if a 650nm 100mW diode would provide this? Kind regards
