Hi Everyone, Today we will make a Usb Charger that will work on a 9v Battery and can Serve any Gadget that could be charged over Usb. It can Serve Apple Products Also.
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
Parts Needed to Make PowerCube :-
(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)
I took 6cmx6cm Measurments
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!
This is to show that it is really ultimate power source,when one battery drains out open the skrews and attach another battery from cube only!
Step 4: Top of Cube
We will now make the 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
As Apple Products have a feature, not to make a duplicate charger for it so we can used this trick to trick that apple product which you are using. In this we supply (2v - 2.5v) in both the datalines to make it think that it is connected to a laptop or computer.
So, we will use (2) 100 Ohms resistor in both Data + and Data - Lines.
Step 6: Attaching All Parts to Top
Now Attach all the Components to Top and Solder!
Step 7: Black Painting the Top and Joints!
Black paint all the Edges and Top because we have not pasted black paper on Top.
OK.. Hope that is looking good now.
Step 8: Decorations... (Optional)
I added some stickers to the cube. Which made it Look Good. I just used simple sticker paper which was available at my nearest stationary shop.
Step 9: Testing!
Hope you could see Charging sign on both phone. This Charger Helped me many times and my phone stayed On,all along my trip!
Enjoy making your own PowerCube...
Step 10: All Done!
All Done! Make your Own PowerCube Now ;)
