Magnetic table lamp

Step 4: Making connections

Put nails in each 3 mm hole. Solder them together on the inside of the cubes.

Each nail of each side represents a negative or positive connection. Starting from the upper left corner you've got positive, on the upper right corner you've got negative, on the lower right corner you've got positive and on the lower left corner negative. Use electrical wires, solder and a solder iron to connect the positive corners together and to connect the negative corners together.

How do you make the sixth side power the cube?

The sixth side is a bit tricky.
I used two methods:
The first method is soldering short wires to the nails inside the box and then to the single nails of the leftover square, finally glue the cover to the box. This is the best (recommended) method.
I started the second method after I finished five cubes. I call it the fast non-professional I just want this project to be done (not recommended) method. It goes like this: put the nails in the leftover square and glue it to the rest of the box. I was lucky to have a voltage on every nail.

Thats what i had in mind. also ive decided to tackle this project. but its my first time doing circuit work. any pointers? i comprehend the rest of it all even the wiring but as far as making a circuit i dont know anything.

thanks for the great project!

Hi jlunquist

If you look closely at the last image in Step 5 you will be able to make out how all the nails in one corner are soldered together and then connected to either +ve or -ve.

Does that help?

Cheers
