Here I come with another instructable... I wanted to make a cell phone charging station that could hold all my cell phone chargers and my cell phones that was modular, and I could take out the cell phone chargers whenever I wanted.
This is because I travel a lot and I always have to take my chargers with me, so this feature was important to me.
Step 1: Find Stock & Design
This is the raw material I used for this project. It's an old wardrobe door that I found in my neighborhood. Recycling!
I could do a rough design and start cutting material, but I preferred to do the complete design to prevent future inconsistencies and to get the right measurements for fabrication.
I used a five plugs extension cord, and also I wanted it to have a switch, so I could turn them all off and save energy.
Dimensions in the last picture are in milimeters.
Step 2: Cut the Wood
I used a file to smooth the rough corners, and sanded the panels to do a future painting job.
Step 3: Assemble the Box
Since I decided to assemble this box entirely with screws, I drilled the masks on the back and side panels, and bored the holes to fit the bolt heads.
After that, it was simple to assemble the box.
Step 4: Testing the Extension Cord / Mount the Door
Step 5: Assemble the Door Lock
Step 6: Fabricate the Small Metallic Parts
Step 7: Note on the Electrical Part
Since LEDs need a low voltage source and it would cost a lot to make one only for that, I chose out of many options to make a simple voltage divider to power this LED. But I was concerned that since the division factor is pretty high (>10), it would consume a lot of current. So, to put it on the minimum current consumption I had to design it and I found (by experiment) that I would need something like 1mA to light a LED at a minimum but visible level of lighting.
So I designed a voltage divider for 127V and did not care about rectifying the sine wave, leaving this work to the LED. The diode here is only to reduce the voltage a little bit further. The total power consumed was less than 150mW, which I considered fair, considering that chargers would consume much more than that when turned on.
(Afterwards I noticed that I could simply put the right resistor in series with the led and it would be fine. So, please pardon me for the bad electrical concepts because I'm not a specialist on this!!)
I made a small board to assemble the components together, out from scrap perforated protoboard.
Step 8: Disassemble and Finish/paint
I painted it white, and the small metallic parts were painted red, two coating layers.
Step 9: Paint Dried, Assemble It Again!
Step 10: Install and Enjoy!
After assembling, install it on a wall and enjoy!
Hope it gave you some ideas!
