im trying to buld a burning laser from an old cpu
:lasergun:
can you tell me what i need from the cpu
Hello all! I am looking to fill some free time and want to build my own simple laser as a hobby. Hopefully I will learn some bulk about circuits as well, because I am totally illiterate in the terms of voltage and capacitors and diodes and the such.
Firstly, this is a great guide and a great start for me in terms of background information. Due to my lack of knowledge in this area, I have a few questions that may seem dumb. I hope I can get an answer anyway.
I am going to attempt to build the breadboard linear driver soon (the driver constructed in the video link). After that, I am kinda confused as to what comes next. I understand the battery and driver module in that image, but what are the black disks and how do they and the one ohm resistor come into play?
Next, can some forum members recommend a laser diode on the weak side and at a reasonable price? Something that isn't super powerful and a simple first-time diode.
I am going to be ordering parts soon. Though I am a newbie, I am serious about wanting to take this up as a hobby and learn through it. All answers and advice are appreciated!
Best,
Chi
