Jaco’s Random Writings

The project has been finished. Well, this iteration has been finished, anyway. In the long term, there are at least one more iteration to go. For this one, the result is quite nice. There are a few problems that need to be sorted out software-wise, but the hardware is done and ready to go. Here [...]

Sorry about the delay, folks. I’ve been very busy. However, to make sure you guys aren’t completely in the dark, I have taken plenty of pictures of my progress for you to oggle at. I had to exclude some pictures of the PC Board I soldered for the Pre-Amp as they came out completely fuzzy. [...]

Ahoy folks!
Been a while. I’ve been a busy man. So here is the progress report. On the side of the circuit, I have the chip reading the input (though it is still a little low). It outputs to Serial a string that says “NoteOn” followed by the velocity (how hard I struck the prong) when [...]

Ahoy, everyone!
Here I have some new pictures of a new circuit I’ve just gotten to work. Instead of using a transistor, I’m now using an OpAmp to boost the signal. It works quite nicely, may I say so myself.

These are the pictures of the circuits. Just to clarify, I marked up the close-up to show [...]

Hey folks! As my first act, I will post up all the pictures of my work so far. This is going to be a big one, so watch out.

This is the steel prong used to generate the signal in the pick-up.

The bobbin (or the spool, if you would like to call it that) for the [...]
