how to make a laser diode driver that enables you to burn paper

how to make a laser diode driver that enables you to burn paper
A cheap laser diode is the first thing you need to make your very own high powered laser capable of burning paper.1000s of laser diodes  have died due to the lack of proper drivers A laser diode is current hungry, it will take all it can get.
i  would advice you to wear safety glasses and not fool around while doing this project  have fun and be carefull

what we are going to  make today is something called as the LM317 constant current driver

so lets make one

what we are going to need is 
1 laser diode (you could hack it out of a dvd drive) x1
2 10uf 16v capacitor or 10uf 63v capacitor x1
3 1n4007 diode x1
4 10 ohm resistors x2
5 100 ohm variable resistor x1
6 lm 317 voltage regulator x1
7 veroboard x1
8 soildering iron 
9 solder
10 heat sink
11 switch
all done !!!!!!!!!!!!!!!!!!!!

if i gave you my email address could you send my a schematic of some sort please

hi I'm having a bit of trouble trying to decipher your schematic, particularly the connections of the 10 ohm resistors to the 100 ohm variable resistor and the regulator. can you give me some guidance on the connections?

f.y.i the spinning thing im pretty sure is the power control.

can you show plzz the schematic diagram of the driver circuit

The 1N4007 is connected wrong in the schematic, if you connect it like that then it will get very hot. You connect the anode of the 1N4007 to the cathode of the laser and vice versa, this way the current will take the path of the laser and not the 4007.

BEFORE connecting this to your laser, don't forget to short the output of this driver. otherwise if there was any charge in the output capacitor, it would KILL your laser!

A connection diagram or a circuit diagram might help people build this.

Just as a passing thought - I don't see how making a constant current power supply will actually improve the quality of the laser? Current from a battery is the same as current from the power supply.

Unless you intend to over drive the laser, in which case you need to calculate your component values with care and be prepared to say by by to the laser when it gives up the ghost.

Might?
Apr 3, 2011. 6:45 AMrickharris says:
Will!

This constant current circuit is good to drive LEDS cheap and few components. If the author doesn't supply a circuit diagram I suggest you look at Steve's circuit here - Same thing.

Should the laser diode in a high class or can it be a class I laser diode?
Apr 3, 2011. 8:58 AMThe Ideanator says:
Do you even have a high class laser diode?
Apr 3, 2011. 10:21 PMtobyscool says:
nope just class I laser diode

April Fool's day, maybe?
Apr 3, 2011. 7:33 AMKiteman says:
Published April 3rd?

Yes, I saw the date, but I don't understand it.
