I have finished my laser and I am using 7 x 4ohm resistors in Parallel to bring 0.57 of an Ohm. This should work out to about 1.4Amps right? I am measuring from the Multi Meter and the mA being Inputed are only 800mA even though I have a resistance of 0.57. I have a pot to adjust the current, so...

I have read about how much these diodes can vary in power and some are better than others. I have seen a lot of posts of people running them at about 500mA is there a reason they are not taking it higher? I have a big heatsink and running it off a LM317 driver with 7.4V at 1.25A. Is it safe, or...

Just wondering, if i got a 10mW green module how powerful would it be. I want to know if it would be safe to take it to point at stars at a public place. Well, you shouldn't take a powerful laser into a public place but is 10mW fine? Obviously with any laser i wouldn't point it at anyone but...

I am building a A140 laser with a DIY LM317 driver. I am using 2x 18650 batteries so when fully charged it is 8V+. Is this enough voltage? I am running this diode to 1.5A but is this enough voltage? It would be a HUGE pain if it was not the required voltage and i have done the set up.. I just...

Hi, i am currently making a 1.5W 445nm laser, and i got 2 pairs of safty glasses from dragon lasers. Before i do anything with my laser i am just checking are these glasses safe? Laser Glasses - UV to Green Lasers Protection 190-548nm :: Laser Safety :: Dragon Lasers When i put them on they...

Hi I a making about a 1.5W laser, I just want to know what size heatsink I should have for a long duty cycle. I want it to be on at 3min at a time. I am currently using an aluminium heatsink which is 10cmx4cmx4xm. I think this is too small. What size do you think I should have??? Thanks a lot...

Is it true? I dunno if everybody knows but i have just found out. I didn't realise that Kipkay is going on cable soon, Your Video on TV! | Kipkay.com This can't be good, if he starts showing people all over the world idiots about lasers and how to build them, he himself may be safe with them...

Just extracted a diode from just a regular dvd player. There was only one diode, it is a canned diode. I think it is 1-5mW, i have a few questions though... 1. Is it Infra Red of a visible red? 2. What mW do you think? 3. What is the postive and negative pin? 4. How many mA should i put...

Hi, i just got my A-140 diode through the mail :drool: I need to know what the LD+ and the LD- of the diode. Has anyone got a picture or somthing? Thanks

Hi, i am making a 1.6W 445nm laser, i have all the parts apart from the potentiometer. I want to make an adjustable laser by using a pot, i am using 1.5A through a 0.89 ohm resistor and a 10ohm pot. I know how to make the driver, i just need help to see if this is an ok pot: Tyco Electronics |...

I am getting a A-140 diode and i want to know if you are able to pulse it. I am making my own driver and powering it at 2A. I want it to be able to pulse really quickly, just wondering if the diode will go to 2W as soon as you switch it on or does it gradually powers up to 2W? Thanks

Hi, i am going to be building a 1.5W 445nm laser, i will be powered the diode at 1.5A and i want to know what driver you recommend for it. Can i have a link too please. Thanks

Hi I want to get this laser module and install it in a waterproof host. Individual High Power Bin Green Laser Module V2 - Detailed item view - OdicForce Lasers Online Shop This laser seems surprisingly cheap, I have bought many times from odic force and is very good but is it true? 120mW for...

Hi, as i am not an ebay buyer, i mainly buy off amazon.co.uk. Has anyone every bought a high power lazer off them which has been over powered or a good spec. I noticed that amazon.co.uk sold 50mw pens for about £30, which sounded cheap, but i doupt that this would be the right spec. Look ...

Hi, this is my first build and my first review :) So i will try do my best. I made this at Christmas time and i haven't had time to make a review, so i have now decided to make one now. I bought this kit from odicforce: Focusing Laser Host - Red or Blu-ray Lasers - Detailed item view - OdicForce...

Hi, i ordered a week ago this laser from odicforce: Compact 5mW Green Laser Module - ACC - Detailed item view - OdicForce Lasers Online Shop I bought it so i could use this laser as a safe laser to use around indoors with out having to worry about my eyes. I currently use 1 CR2 battery which...

Hi, i noticed this and i straight away knew it was NOT 200mw for the price it is.I was curious how many mW though? DealExtreme: $46.81 200mW 532nm Green Laser Module (3V 11.9mm) If it was a 120-150mw laser that would be a good laser for the price. Has anyone done a review? Thanks

Yes i know that you need 20x cd burners to get high bower buring lasers, but if i got a cd rom will i be able to get a 5mw laser out of it? And a 5mw IR laser? Just wondering... Thanks

Hi, The plan is that i am going to build my own driver for when i get a 445nm A-140 1W diode, i will be running it at 1250mA and having 7.4v by using 2x 18650 batteries. The parts: LM317 1ohm resistor 47uF 35V capacitor 50ohm pot IN4001 diode A 1ohm resistor allows 1250mA to be drawn, that is...

Hi, i am a bit confused about the pin out on the A-140 diode. Here is a pin out diagram: I am making my own driver with this diagram: I am not using a host i am just connecting it up to a power supply. I have seen that you need to solder the "-" to the case pin, this doesn't seem right for...
