Space saved, junk repurposed, plus, it makes calculus and physics homework look all scifi snazzy!
Step 1: Scavenge Scanner Bed
Step 2: Cut and Drill Plastic
I drilled through one of these gaps on either side of the plastic. The resultant holes would later be used to hang the whole board on the wall with nails. I also hacked open a switch sized whole in the center of the board. Knowing that one side of the terrible cut would be against the wall and the other side hidden behind metal gave me some peace of mind since, as you can see from the pictures, I'm not exactly precise with my rotary tool and my cut lives up to the term "hacking".
Step 3: Create Battery Mounting Bracket and Marker Holder
During the 24 hours that I left the Sugru to dry, I did the math on the LED circuit and decided on the physical layout of the lights. I chose the top and the side of the glass because that was where I could best hide LEDs. The top is obviously opaque, but what may not be clear from the pictures is that there is an opaque strip running down one side of the glass as well, perfect for hiding wires and LEDs
I had originally wanted 4 LEDs running along the top and 4 along the side, but at 3 V an LED, that would have required a 24 V power supply. . I realized that since 2*9 V would give me 18 V, my best bet would be mounting 2 9 Vs and using only six LEDs; 3 on top and 3 on the sides.
Once I knew my power requirements, I could make a battery mounting system. I have a pretty large supply of old brass mounting brackets lying about. A little bit of searching followed by a little bit of bending was all I needed to find two pieces of brass that I could screw into the plastic to hold the batteries in place. In order to get power out of the batteries the way I had them held in place, I cut a 9 V battery connector in half and attached the positive lead to one battery and the negative lead to the other, allowing me to maintain the 18 V series necessary, and keeping the batteries oriented in such a way that they laid flush against the wall.
Step 4: Create Circuit
All in all I love the project and use it every night while doing homework. Not only does it save me desk space, but I feel all sciency while doing it!
