Step 72: Handle/Electronics: Posterity

The second switch, built with the help of my friend Lyle, is a much cooler thing, but it is rather difficult to build.

It consists of the same scavenged USB hub (but with all the electronics desoldered and the grounds and +V of every USB plug wired by hand), a 9V battery, a screwdriver handle, and some old telephone parts.

The basic idea was to make a handle with a light-up switch so it would be obvious that all systems were working properly. The downside of this switch, though it is very effective, is that it is a lot of work to build. You must hollow out a screwdriver handle, mount bearings inside it, find a light-up switch that doesn't suck, etc etc. In spite of all this, I've tried to include enough photo documentation that you could reproduce it if you like.
