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 are some pictures for everyone to look at.

There are two issues this project faces. The first is that the slider is an audio slider, not a linear slider. That means that the values for the slider increase on a logarithmic scale, rather than a linear manner (1, 2, 3, 4, 5… etc.) as you move the slider. This means that the distance between notes increases exponentially. Makes playing it a little awkward. I could probably come up with an algorithm for the firmware that allows it to convert the logarithmic values to linear values. The second problem is that the preamp was not completely calibrated for the new prong. The notes coming out are a little too soft and there is much variance in the loudness of the notes. They seem to be either on or off. Again, something I can do in the firmware.

However, I’m not going to fuss too much with it right now. The main thing is that this works in some fashion or another. I will definitely have to have these issues sorted out by the time the Senior Show rolls around in the Spring (at the soonest by the time I submit this to the jury).

Right now, I have a presentation to worry about. For those coming, it’s on Wednesday (tomorrow) at 6 PM and it will run until about 8 PM. It is located in the Connelly Auditorium on the 8th Floor of the Terra Building. I believe I have the exact address for it on the previous post, but it’s on Broad St. between Walnut and Locust St. in Philadelphia.

I’ll post a video of it being played sometime after the presentation as well as a sound file recorded while playing it.

I feel so relieved that this is actually working and finished.
