I’m not sure if this picture does justice to the surface of this work bench. It’s a joy to work on and looks a lot like the clear hemlock sold on the west coast. With a couple coats of shellac this work bench came out nice.
I worked with my friend Andrew to install this in the basement of his new house. It is a simple 2×4 frame with the 3/4″ plywood resting on top. We prepped a 2×4 ledger board for installation on the cinder-block wall. The ledger was part of the frame, and after the frame was fully screwed together we used tap-cons to fasten the ledger to the wall. I held the frame up, as Andrew installed the two legs (each made of 2 2x4s).
While we have already populated the bench with equipment, his project is still under construction. I have ideas on track lighting directly above the bench and we have 2 shelves (of the same plywood stock) to install above the bench. See the following picture to see what we’re working with at the moment:
We made some interesting discoveries today. First, after much confusion, we determined that some of the resistors have developed corrosion on their leads. The result is that resistors have a voltage drop of only a fraction of what the power supply indicates they should.
Second, we were able to explore the operation of the USB function generator with a small speaker. The function generator came as part of my oscilloscope, but I’d never gotten a chance to use it. The coolest thing we simulated utilized the sweep function: where the function generator output a signal that moved from one value to another across a period of time. We used a square wave, 5HZ to 50kHz across 10 seconds, using a ‘piano-type’ pulse and got some very interesting sounds from the speak. Very geeky indeed.
All in all, it was an exciting day. There was much talk about the potential for brain-computer interfaces, such as the ones distributed through NeuroSky. This may be the next project, or something on the horizon at least. Based on the amazing results of Collin Cunningham, a simpler project seems possible. See his video entitled ‘Brainwave Beats’. We’d like to use our brain-states to control the operation of a simple LED light, and possible utilize the Neurosky equipment along with Arduino stuff.
