And what do we have here, a topic about my little project
A guy on youtube sent me a message about this thread going on on this forum, so I decided to sign up. My name is Koen, almost 19 years old, student Mechanical Engineering, and a complete guitar addict. I'm from Holland, so excuse me if I make mistakes in my English
I see you got pretty much everything figured out about my LED system. Well, lets confirm a few things to make you guys all happy:
- Diodes:
The diodes are there to make switching between the two modes possible. Diodes conduct electricity in just one way (the way the arrowhead is pointing). If you would switch the circuit into touch-mode and fret a string without diodes, then all the leds would light up. Try to 'walk' throught the circuit and let the diodes act as one way streets. It should make sense
- Connection with frets:
It is very easy. I grabbed a small drill bit (1 mm, yes we use the metric system here) and drilled right through the fret slot. I put the negative led lead through it, and pushed it into the slot. Because the led lead is pretty flexible, it acts as a spring system. Once the fret is tapped in, the lead gets pushed down further into the slot, but it keeps touching the fret because it wants to spring back in its previous position. There is no glue or conductive stuff used at all.
- Replacing burned out leds
You don't. Leds hardly ever burn out, because they are constructed in a much simpeler and more reliable way than light bulbs. And if they burn out... then you're screwed basicly
Any further questions are welcome of course. But don't expect a quick reply. I'm going on a 2 week holiday in a few hours ^^
at psw: thanks for the hats off
