So I'm just tinkering around looking at 4 old computers i have sitting around and decide i want to make a laser pointer.
I have a few diodes from dvd burners already but I want to make a driver to protect them.
I tried locally to get the diffrent parts needed on the many tutorials but no one in this town has any of them, and usally i get a funny look when I ask.
So I figured the parts may be found on my old Pc's.
So far I have several resistors and capastors but dont know how to tell what they are rated for but found websites that will help me determine that.
Next I notice everyone says I need this LM 317 chip, I didnt find one with those serials on it but I did find a "LT 428" "MO8PEC" "LT 422" "2sc2625" and one with no labling.
Im wondering if anyone knows if those will work, or how a person could test them and compair to a LM 317.
And lastly where could one find a pot in either a PC or any home appliance.
I did find most of these parts in the power supply section of the PC.
