First signal generator attempt

Independent Study

1st Signal Generator Attempt

This week has been one of progress on the side of the components.

I have probably mentioned in earlier posts that I found other people’s attempts at creating a homemade signal generator (version 1, version 2). I tried to follow the circuit diagram, but my attempt was not successful. My lack of understanding of what I am doing, and also the fact that I wasn’t able to gather the exact parts may have something to do with it. Next week, I’ll try to obtain help and move this further


Lasercutting v1 and v2

Flatworks v1 and v2

On the side of the pickup flatworks, things have moved forward a lot. On top of being unable to get an appointment sooner with the Concordia’s Digital FabLab, their laser cutter was broken.

In order to move forward, I decided to explore alternative spaces. I discovered échoFab, next to ÉTS. On Thursdays, they accept non-members, and I was able to get a few versions of the flatworks cut out. Their lasercutter also cuts up to 1/4″ plywood, whereas Concordia’s Digital FabLab’s only cuts up to 1/8″ plywood. This discovery will be useful to another project.

These versions allowed me to discover a few things:

I’ll design a new version of the flatwork and I’ll go next Thursday to have it cut out.

Spooling Bit

Spooling Bit

Wednesday morning, the Metal Shop’s tech had no appointment, so I was able to get his help to weld the spooling bit which I mentioned before. It may be a bit big, but I think it will allow me to also wind coil around real guitar pickups, not simply the custom ones I am making for this project. Maybe I should use a smaller piece of wood though.

The Key Saga

On the admin side, I still have not received my key to the lab, forcing me to depend on the other lab’s members’ presence for me to access my project’s parts. The administrator told me there is an overwhelming demand of keys at this time, so I was promised that I’d receive it next week. Once I get that, I can stop annoying the different lab techs and actually take appointments!
