I used to have an Identicle car to this. A nissan 300zx twin turbo w/ body kit and black on chrome rims and 2 800 watt sub with a 4 channel 2000 watt sub. I sold it Though and bought a camry because it only takes premium gas and I couldn't afford its insurance. heres a pict but its now mine but...
Well I went to my friends house who is a Girl, and she took my laser and started playing with it and was amazed. I just thought I share that, I gave her the laser too.
Just an FYI for some people, I went to store and picked up an identical "looking" flashlight, but the head inside is smaller and the head doesnt unscrew.
I Have a circuit very similar to this except I use an smd capacitor and silicon diode.
BTW this looks nice and will help new comers you should make some and sell them.
when I first made a pointer I made it cheaply if you want Simple then you can use a 1.2-2 ohm resistor(I suggest 2 ohm) which will give you from 160-225ma and a 47uf capacitor. My pointer like this still works fine but its still always best to use a driver.
