My first electronic gadget: TP cable checker
April 18th, 2009
Today I went to Omega Verksted at NTNU with the plan to check weather or not a TP cable is working. With some help from Espen Øyby, a friend, I got the design ready. After designing the circuit on the computer we printed it on a special paper, which we then laid on top of the circuit board. A couple of minutes in a powerful light it was ready for acid. When we took it out of the acid and washed of the photoresist I had my circuit board.
The entire thing is a quite simple circuit. It consists of 9 LEDs, 9 resistors, 2 AND port blocks and 2 female RJ45 inputs. After soldering everything together it worked!
If your interested you can see the design layout here.

Hehe, du får komme innom. Jeg må dog kjøpe et 9V batteri først.

Should I go to a community college first in order to become an electrical engineer?
