i m going to show a DIY project which is cheap though handy when its dark out there :)
Items Required :
1. Ink Cartridge cover
2. Line PCB board
3. 2 LEDs
4. Old battery
6. Charging point
1. Soldering iron
Step 1: Making a Simple PCB Using Line PCB Board
take a line PCB board . choosing this PCB board because its so cheap & good enough for this project.
here i cut it down with a scissor but you can cut it down with knife or other things that is preferable to you.
here is the catch :
Cut the suitable size leaving the 2 lines in middle because those will be used by the LEDs.
make sure you are piece that u cut have at least 4 lines. This is to make sure LEDs won't miss the holes of PCB.
Step 2: Using the Old Cartridge Cover
- Tear apart the thin plastic from the cover
- Clean & it well before 1st use
- the BORDER line showing the placement of our LEDs. (you can improvise as you want)
- take a Soldering ion to make hole on the border panel according to the width of pins of LEDs
Step 3: LED Setup & Soldering
- check the LEDs are going through the PCB that you had cut down. (as 1st pic shown)
- now put the LEDs on the cover of cartridge
- next attach the PCB with LEDs from under the cartridge.
- then solder it
- attach (+ve) pins with Red wire & attach (-ve) pins with Black wire with the help of soldering iron
Step 4: Switch Setup
take a switch of 2 pins
you can cut down or even you can make a hole with soldering ion to set your switch & use some hot glue with it so that it will attach with the cartridge.
Attach the Red wire with 1 point of Switch.
Step 5: Battery & Charger Point
As we all know battery has 2 points (+ve) & (-ve)
i used a charger point which is suitable with Nokia charger.
now attach the (+ve) side of battery with + points of charging point. & the other side with other pin.
Step 6: Finish
now take another wire from ground side of battery to attach it with the other pin of SWITCH. so that whole circuit will complete.
Now recharge the battery & after that enjoy :)
the battery battery has about 3.3 voltage & as the LEDs are attached in parallel so it will be enough for both them & enough amount of Ampere through them. In this setup the LEDs will run for much time. But in need of high intensity light you will need to put a small register to increase the ampere between the LEDs.
