It is a Easy Project which can be made by Everyone.
Just a Warning Before i Start : There is a risk of Getting the Wires wrong by you and damage your gadget.
Step 1: Parts Needed
(1) 5v Regulator (1)
(2) 100 Ohms Resistor (3)
(3) Blue Led (1)
(4) USB (1)
(5) 9v Battery (1-3 because it has more capacity)
(6) Black Paint
(7) Black Hard A4 Sheets
(9) Nuts and spacers
(10) 5mm Hard Cardboard
(11) Battery Clip
Hot Glue Gun
Step 2: Making of Cube (Hard Part)
It was perfect to make a small cube which will be having enough capacity for batteries.
I Used 5mm cardboard.
Mark lines with sketchpen and scale.
Now Cut the cardboard into 6cmx6cm Squares
Join the Squares (leaving Top Square) with eachother by SuperGlue (I Used Fevikwik) hot Glue all the Sides with eachother (inner side edges only).
After we have made the cube. We will sandpaper all the edges and upper edges of cube.(Sorry no photos)
Step 3: Capacity! | 3 Battries!
Step 4: Top of Cube
I Have made the layout.
Small hole near switch is for heatsink.I used a skrew and nut for this. (Cardboard is a bad conductor of heat so i have to put a heatsink to let out the heat in air).
Step 5: Schematic
So, we will use (2) 100 Ohms resistor in both Data + and Data - Lines.
Step 6: Attaching All Parts to Top
Step 7: Black Painting the Top and Joints!
OK.. Hope that is looking good now.
Step 8: Decorations... (Optional)
Step 9: Testing!
Enjoy making your own PowerCube...
Step 10: All Done!
