Here is the world’s first BIC style laser lighter! Butane is outdated. Time to use blue burning lasers! Watch the video and then build your own!
Or, Read the instructions below.
What You Need
1. BIC lighter. (The non-electronic, standard version) You may want to get two in case you crack the first one.
2. Blue Laser diode and mini-housing
3. Mini-driver circuit
4. (2) 1.5V button cell batteries
5. Mini Momentary switch
6. (1) 4 to 4.3 ohm resistor
7. (2) small magnets
8. Assorted wire
Prepare the lighter
Disclaimer for those that don’t know lighters are ‘dangerous’: Lighters contain butane, a flammable liquid that can catch fire, explode, burn you or your cat. And, lasers are also dangerous. Don’t ever point any laser at yourself or any living thing.
1. Remove the flint wheel by prying it out at the edges. DO NOT BREAK THE BRACKETS. Once you release it a spring and flint (and other small stuff) will pop out and
fly across the room. Go get them. Keep the flint wheel.
2. Remove the shiny shield by prying it out at the edges. DO NOT BREAK THE BRACKETS. Keep it.
3. Flip the lighter over and take it to a safe place. Putting on safety glasses never hurts. Stick a small pin or paper clip in the hole and it should contact the metal valve in
the base of the lighter. Gently tap it with something to release the butane. You may need to tip it over to make sure all the butane is gone. You should hear something
small rattling inside. That’s the valve.
4. Remove the red button that releases the butane. Keep it.
Gut the Lighter
The entire inside of the lighter needs to be gutted out. There are probably many ways this could be done but I found the best is as follows:
1. Using a Dremel cutting wheel, make two small slits in the white cover on the bottom of the lighter. Careful not to nick up or cut the housing or it will look crappy.
2. Use snips, pliers, X-Acto or whatever you need to remove most of the plastic on the white cover. (The cover is sonically welded to the housing so it cannot just be
3. Use a sanding tool or dremel attachment to completely remove all of the white base from the housing. This is time consuming if you want to do it right.
4. Remove all of the inside of the housing as far into the lighter as you can to make room for the mini-diode housing. This is a painstaking process and you may have to
resort to burning the plastic away with your soldering iron. Don’t inhale the smoke or get it in our eyes. Burning plastic is no fun.
Final Lighter Prep
There are two main holes at the top of the lighter.
One is the where the red button you removed earlier makes contact with a valve to release the butane and on the other side where the flame exits.
Both of these holes need to be drilled out to accommodate the switch and the mini-diode housing. Use drill bits and CAREFULLY drill the holes out. (A small bit will be
needed to drill out the little valve.) Don’t worry about the center area where there is another hole. Stay away from the brackets in the middle because you will need those
to reattach the red button later.
Building the Circuit
NOTE: This requires an experienced solderer and a real good soldering iron with small tip
Wire the driver according to the following picture. The second picture is the flip side of the driver.
Be sure to add the resistor and the switch as show in the the final wiring pic.
Using a multimeter set to check milliamps, put the leads between the end of the resistor and the diode. Power it with no more than 3 volts and adjust the pot on the driver
to no more than 170 mA. I used 2 button cells, taped together on the sides, harvested from an Energizer 12V 123 battery I also used two small magnets to attach the (+)
positive and (-) negative leads from driver.
Install the Laser circuit
After confirming that everything is wired correctly, it’s time to put everything inside the lighter housing. The diode goes on the former flame side and the switch is pushed
in to the side where the red button switch was (See the next step for details). I used hot glue to secure the switch and diode after lining up the diode so the beam cleared
all areas of the housing.
Cut the original red button in half leaving just the two small tabs that are secured in the housing holes.
You will have to play around with the exact height of the switch in relation to to the red button. Re attach the flame shield. After I shot the video I found a small rubber
stopper and cut it in half, then pushed it inside the base of the lighter to make sure the driver and batteries stayed put. .
Your Cheapy Laser Lighter Burner is complete!
Use responsibly! Lasers of all types should never be pointed at your self or any living thing.
