Created a video, burning a match and comparing the LASERs

By the way i managed to make a 150mw laser thanks to your advice!

does anyone know any 1w laser diodes???

next time i'll solder to veroboard

yes

Built the driver myself Thank you to LuxorLasers147

im gonna build it as soon as i recieve the parts (they are still in transit) :)

i do also have a voltage adpator thingy (idk what its called) that plugs into mains and you can get a wanted voltage (which is between 5 to 13 volts if i remeber correctly)

aaaaaaahhhhh ive started a war. K guys im just gonna use some lithium ion batteries i salavaged from a laptop battery, they have a volatge (when combined of like 10-12 volts LM317 takes 3v + Laser diode 5v + volatage drop and fluctuations = around 10v

Still unsure what voltage battery i should use.

thank you very much

Yeah im starting with a low power laser first, and the circuit i am using seems fine to me. I think Encap didnt realise i actually did have a plan, i do have a plan i just didn't show it. And WizardG didnt read my post correctly. My question was just about what capacitor is appropriate

Ok, thanks for the info I thought that because the laser diode want 5v and the LM317 wanted 3v it would be ok Ill use a 10v or 12v battery supply instead. :)

Just read the parts list...

Did you not read what i said, i said the values of the components will be different! I said i was foing to use a 17ohm resistor and a 9v battery, read what i said. I said i was using the diagarm to help me connect everything up, not that i was gonna copy the diagram exactly!

Encap yes i do have a plan. I may be young (not 12 yrs old), i do have an idea of what i am doing! Before you say you need to be 18, has anyone ever actually complied with age limits online. Legal age to have an email is 13 i had one multiple years before that! By the way i dont care if i can...

fi fine then I will do it without your help!

So i think i should add a capacitor to my laser in case of voltage spikes. However i really dont know which one i need. I am going to power a 50mw laser with lm317 (i also want to know what volatge should the battery be???). Will a 25v 10uF capcitor be appropriate???

yeah i kinda do wanna be able to see... ill order them when i know everything i am doing.

my dad has a bunch of weird and wonderful resistors, i just searched around and found one eventually
