Bad Vibes Desk: Update (The Motor)

It’s been a bit since introducing the Bide Vibes Desk project. And since it’s due tomorrow I figure it’s time to go over what’s happened since our last episode…

Bertha

Here’s the spec sheet for you motorheads: Bertha’s Spec Sheet

The Mount

You might notice, as I did, that there’s no engineered-in way to mount Bertha. Which proved to be a pain in the ass.

I considered buying some sort of pipe fitting or bracket, but that would have been expensive. I also would have had to customize it to some degree. So I decided to prototype a mount with what was lying around in the meantime, while I researched a longer-term solution.

To the junk pile!

I found a 2 x4, cut it down to size, drilled a hole, and cut in half. Using a couple of wood screws I created a surprisingly decent clamp to hold the motor in place. I soldered on the wires you see dangling out. In these photos they’re temporarily connected to a bench power supply that I was using to test Bertha’s vibrational strength.
