Introduction: Super Capacitor Flashlight 2.0
In this instructable I will show you how to make a super capacitor powered flashlight.
This means that you can make a flashlight that can charge in seconds and last for around 15 minutes depending on your capacitor.
Note: I just finished calibrating my scratch built RAMPS controlled printrbot simple so I will make a lot of 3d printed instructables now Just suggest any ideas for new projects!
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Parts and Tools
These are the parts and tools you will need to make this project:
1 farad 5 volt super capacitor
5 mm led
USB male cable ( stripped)
Soldering iron and solder
50 ohm resistor(The capacitor max voltage is 5 volts so we want to lower the input voltage)
Step 2: 3d Print Case
Here are the stl files to print this:
Step 3: Make Circuit
Solder some wire to the negative lead of the super capacitor to the negative lead on the led and wire the positive end of the super capacitor to a momentary switch. Wire the other side of the momentary switch to the positive side of the led. Now solder the positive end of the USB male plug with a 50 ohm resistor going to the positive end of the super capacitor and the negative wire from the USB male jack to the negative lead on the super capacitor.
Step 4: Fit in Enclosure
Put all of the parts in the enclosure you may need to file down the rectangular hole for the USB plug.
Step 5: Finished!
