Hi Friends, Today we will Make a Powerfull and Long Lasting Torch.And... It's Rechargeable too!
Step 1: Parts Needed
1.Li-ion 3.7v Battery
2.1N4007 Zener Diode
3. (2) 5mm Led's
4. (1) 10mm Led
5. (1)5mm Blue Led
6. DC Jack
9. Glue Stick and Soldering Iron
10. 220 Ohms Resistor
Step 2: Designing Layouts for Cutting/Melting Plastic
Just Make Sure that You Drill/Melt a Big Hole for Big Led.
Step 3: The Schematic
Donot Forget About the Zener Diode Which will Mostly Prevent the back flow from battery.
*Warning* - There is a LOT of RISK in charging the Batttery Directly from the 5v Mobile wall Charger so,Be Careful and I will NOT be Responsible if any Wrong Thing Happens.
Don't Forget that the Charging Time of Battery should be only be 50 min when it is empty and charged Directly From 5v Wall Mobile Charger.Otherwise Batttery could Explode if Over - Charging is Done.
Step 4: Hot Gluing and Soldering
I Used Lighter to Melt the Glue Stick (if you have an hot glue machine then do with it :P)
Step 5: Fully Assembled!
Step 6: Black Taping All Sides to Seal It
Step 7: Testing the Brightness!
Pocket Torch for Everybody which is Simple and can be made by Anyone!
Just 7 Easy Steps :)
