Make:Electronics - Experiment 20

14 February 2012 at 12:45 am


Lot’s of stuff to do other than play today, but I managed to finish experiment 19 - a “code lock” based on the 74xx series of chips. This part of the training is sort of a “repeat” in that I’ve read it so many times during school, however building circuits with it makes it a lot more fun. I couldn’t complete the project entirely as the relays I got from Make didn’t work at all (same for others) but the main part works like it should.

Really looking forward to tomorrow - I should manage at least two more experiments! :-D
