Found a guide online that showed you how to make one of these, and I tried it out. I am pretty happy with the results. I am very careful with the pointer, and keep the batteries out of the unit at all times unless it is being used. I also do not let others mess with it, as it is very dangerous.
The music is made by me
UPDATE!!
This laser dies after a while (very short while I might add).
I followed a guide from a person called kipkay but here is the problem (taken from laser pointer forums)
“I saw KipKay’s laser flashlight hack, can I have some help?
DO NOT follow KipKay’s laser flashlight hack. In that video, KipKay hooks the laser diode directly up to the batteries with no current regulation at all. One of the biggest “no-nos” in the DIY laser hobby is to hook a laser diode directly up to batteries. This is why KipKay’s laser hack doesn’t work: there is a difference between light bulbs and Laser Diodes. Light bulbs are controlled by the the voltage, that’s why the bulb itself is working so well directly on the supplied energy. Laser diodes, however, as well as other semiconductors, are controlled by the current. So, if you try to feed a LD directly with the batteries, there is nothing that controls that current. Let’s say that the LD needs 3.0v, 200mA to operate and you hook it up to the batteries (3.0v), will it work? Yes it will, but with even the slightest change in temperature will make the LD require less voltage and a HUGE amount of current will flow through it, and kill it. See Ohm’s Law.
In short, driver boards greatly reduce the risk of voltage spikes and current over-saturation.”
So what that means is too much power is going into the laser = a dead laser.
It is much easier to buy the laser!
There are several good sites for nice lasers for cheap
www.dealextreme.com
www.Kaidomain.com
They both have some nice lasers but deal extreme has stopped shipping to the US because of new regulations. You can not legally buy over a 5mw laser = a normal laser point that doesn’t burn or anything. I recommend finding someone who is willing to buy it from another country and ship it to you or buy from kaidomain —either way works
Hope this helps.
