I just completed my first laser today, it is a PHR-803t using a flexdrive set to 95 mA and 3 AA batteries. I couldn't find a very good house for it so this one is only temporary. It can light matches and burn through tape and cd cases very well. I am very happy with my first laser.
Is that an Altoids tin? :beer: Nice work! While it may not be much of an issue with a PHR set to a relatively conservative current, a heatsink would be a good idea when you find a more permanent housing.
It is now in an Altoids tin. I still need to buy a switch for it though. I have noticed that it can focus very well within 1-5 feet but after that it cant focus as well.
The finished build in an Altoids tin with a safety switch inside and normal switch outside. Axis module seems to be a good enough heatsink as the diode is only running at 95mA.
I took it to school and my honors physics/AP Chemistry had me do demonstrations in three of her classes.
