Paper and cardboard circuits

A cou­ple of years ago i found out on the “inter­nets” that you don’t really need a pro­to­board or a cir­cuit board to make your cir­cuits come to life, the idea was to fold a piece of paper with the cir­cuit design in it (com­po­nent side and cir­cuit dia­gram side) and then insert­ing a piece of card­board in the mid­dle.

The main idea was the eco, recy­cled “thingy” since cir­cuit boards are not so eco friendly and take a bunch of time to get recy­cled by our mother earth, also the eco­nomic side (paper and card­board are almost free), instead cir­cuit board­ing takes a long time and it’s haz­ardous for the envi­ron­ment.

So here’s what i do :

1- print the schematic you want (be sure to include on the sheet of paper both sides of the schematic (com­po­nent side and schematic)

2-fold it (the idea is to fold where the com­po­nent side meets the schematic)

3-cut a piece of card­board and insert it in the mid­dle of the sheet of paper

4-glue both sides on to the card­board (now you must have a beau­ti­full cir­cuit board made of card­board)

5-with a nee­dle pierce (com­po­nent side) all drilling holes into schematic side

6-insert the com­po­nents (resis­tors, ic, capac­i­ta­tor etc..)

7-turn it back (schematic side) and start to sol­der (be sure to folow the traces on the paper), the best way to do this is to sim­ply bend the leads of the com­po­nents and sol­der them together, if you have a large area were the lead is not long enough just use a wire or some­thing sim­i­lar.

8-have fun
