i always wanted to build a laser-pointer/burner
that can burn matches, pop balloons, and possibily turn on fire.
due the safitly you need to add at least 2 switches, and 1 pushbutton.
this will decrease the risk of acidentally burning someone's eyes out.
1-Adjustable Voltage Regulator LM317T
1- 100 ohm Potentiometer 2- 10 ohm Resistors 1- 1N4001 Rectifier Diode1- 47uf 35v Capacitor1- Any Size PCB Board1- Any Solder1- Any Soldering Iron1- Power Switch (I like momentary push buttons)1- 12x30mm Aixiz laser housing Click Here2- Spools of wire ( Red and Black )- You will need at least a 6 volt Power source.
Step 1: Soldering the Materials
if you have a prototype pcb you can solder the parts yourself
if you want to do it more advanced, you can make a custom pcb board.
and then solder the parts more easily,
(i have yet to fully solder mine) (i dont have a good working laser diode yet)
Step 2: Bonus:
if you want to make it look more cool
you can buy a cheap ass plastic toy gun with sounds. (it needs to be large enough to fit the protoboard)
or 3d print a case yourself
Step 3: Picking the Laser Diode
there are many different types of diode's
old DVD drive
3-5$ from internet
look at their intial specs, to look how powerfull thei are
if you want to do it easier you can use a arduino diode, or a pre-build diode with just 2 wires.
Step 4: Testing
now you have finished the laser,
you can try testing it our.
if it does not burn/pop things at once, you might want to use some lenses, to confine the laser beam to a smaller one.
for the lenses, i dont know wich factors you need.
(the smaller the laser-beam the more powerfull it is)
