I built this flashlight so i would have one that used sunlight and didn't require any batteries. When fully charged it can stay lit in approx 30 minutes.

Step 1: What You Will Need

Step 2: The Circuit

Step 3: Putting on the Solar Panel

Step 4: Add the Capacitors

Step 5: Mounting the Switch

Step 6: Mounting the LED's

Step 7: Connecting the LED's

<p>Hello!</p><p>This project is awesome and just what I was looking for. I am traveling to Honduras in a few weeks with a group of engineering students and we are attempting to teach children at an orphanage about solar energy. On top of that, we are wanting to give these children a sustainable technology they can use in their everyday life - hence the flashlight. Due to the frequent and unpredictable power outages the orphanage faces, I was wondering if there was a way to make this particular design last for a few hours rather than 30 minuets. Would replacing the capacitors with rechargeable batteries help? I would appreciate any suggestions you have.</p><p>Thanks!</p>
<p>normally the cap's limit voltage will be twice.Ex your solar is 5.5 then for safety you should use 12V or 16V. Caps are as danger as a lipo battery.IT EXPLOSES!!</p>
<p>If the capacitance of the super capacitors were higher, would the flashlight stay lit longer?</p>
<p>Personally I'd love to see some more textual explanation of your steps, but all in all you nailed it! The project looks really professional and sleek!</p>
Nice profile pic ;) lol
<p>Thanks lol :-D</p>
<p>Very awesome!! Simple but nice!</p>
Very nice instructable. I like your use of supercapacitors!
<p>Thanks :-)</p>
