Ever need a flashlight, but don't want to lug around a big one? Or you wanted to use something that didn't take up as much energy as a regular-bulb flashlight? Then this flashlight is perfect for you! This is really easy to make and only require a little bit of knowledge in electronics. This is also better than most altoids lights because you can change the battery if needed and it uses 3 LEDs rather than one or two.
WARNING: THIS INSTRUCTABLE USES POWER TOOLS AND ELECTRICAL COMPONENTS, I AM NOT RESPONSIBLE FOR ANYTHING STUPID YOU DO TO YOURSELF WHILE MAKING THIS FLASHLIGHT. WHEN USING THE DREMEL, IT DOES MAKE SPARKS, SO BE CAREFUL AND WEAR SAFETY GOGGLES!
Step 1: Ingredients
3- 5mm High-Brightness LEDs
3- Snap-in LED holders
1- Switch of your choice. I used a sliding STSP switch.
1- 9V battery, or other battery. Just know how much power your LEDs need and what resistance to give them. I used this instructable to find out how much resistance to use.
1- 9V battery snap
Solder & Soldering Iron
Heat Shrink (optional)
Drill will assorted drill-bits
Dremel with cutting wheel & sanding attachment
Safety goggles for when using power tools
Step 2: Wire the LEDs in Series
Step 3: Adding a Switch
Step 4: We need power!
Solder the positive lead of the battery snap to the other lead on the switch.
Solder the negative lead of the battery snap to the negative lead of the LED setup.
Use heat shrink when needed.
Note: I didn't need resistors (unlike most LED projects) because I was using a 9V battery and each LED required 3V to light up. (3 LEDs x 3V of power per LED = 9V of power total)
Step 5: Mounting LEDs
My LEDs weren't really "snapping in" to their holders, and I drilled my holes a little too big, so I just used a little super-glue around the holders and the back of the LEDs (try not to get glue on the front of the LEDs because it dries white and will reduce the visibility of the light).
Step 7: Mounting switch
Step 8: Done!
Step 9: Hurricane Laser Cutter...
First of all, I like to do papercraft. Now I am using a hobby knife to cut all the pieces out, which makes it look terrible and is very time-consuming.
I also like to do some woodworking, and this would allow me to make precise cuts on my projects.
Third, my dad runs a service called Memory Links (www.memorylinks.com) and has to send his pieces off somewhere to get them laser cut. My dad would most likely be very excited if I took the laser cutter to his office so he could manufacture his own Memory Links.
Fourth, I make paracord bracelets and have been wanted to put dog tags on them. I have the dog tags, just no way to put custom messages on them.
Wow, I have a lot of uses for a laser cutter! Please vote for me!
Wait! One last thing. I will also post an instructable on everything I do with the laser cutter if I win it!
