About: I am new to instructables and have a lot of interest in diy projects and want to build more multirotors in the near future. For the time being I have designed quite a many of them! I also love etching circuit …
Some times one's car breaks down at night in the middle of no where and there may be no light to fix it! For that I have made an easy solution to fix that problem!
An easy USB rechargeable magnetic led assistant!
Step 1: What You Need:
You will need:
- Some skills!
- 1w/2w/3w leds (one or more. Actually one 2/3w led will do. if using 1w use two of them)
- A small 3.6v ni-dc 100mah and higher button cell battery (use more mah count battery if using more leds/more watt led)
- Male USB port
- small Perf board
- Magnet
- Soldering Iron and soldering wire
Step 2: Prepare Your Board
Use the schismatics above, it will help you...
Remember: Connect the USB +5v to the positive side of the battery and GND(ground or negative) to the negative side of the battery. NOT vice-versa or you will screw up the battery or the usb port!
Step 3: The Final Steps!
Keep this charged in your car and use it when in need or a breakdown! :D
OH yea another thing you could us it for is: To stick it on to a fridge door with all other souvenirs!
