Electric Motorbike Update

Here's an update on the electric motorbike project:

(Yes, it's crap quality, a better one will be uploaded soon.)

The back wheel hits 100mph with no load on the bike.

The battery rack:
Next we will be adding the batteries onto the frame and implementing a pwm throttle.

Tube Tester

This is a tube tester. More specifically, it's an EICO model 625. It hasn't been tested as of yet, but it looks to be in good working condition. This will definatly help to test the bucket of tubes lying around.

Senocore ss137

This is a picture of the Senocore ss137. It is essentially a TV tester. With the throwaway culture of modern life, we've got more TV's than time to spend time fixing them, but I'm sure that a use will be found for this piece of equipment or its components.

Electrosurgical Generator: Cameron Miller 255

Here's a weird one:

This is a picture of a Cameron-Miller 255, an electrosurgical generator. It is used for different kinds of surgery, including cutting and cauterization. It accomplishes this by heating up the tissue between the electrodes with current, in the range of 0-100 watts. It's pretty easy to tell that this was made a while back because it is constructed from more modern ones, but the label was removed and a quick search reveals no results.

There might be some useful parts inside which could be reused, but I think it is best left off until someone figures out a use for it. Any ideas?

Terminator Revealed?

Although it looks like the terminator's faceplate, it is actually a bent Faraday cage / rf shield from an emac. (below is the unbent one straight from the emac)
These were included in the design to limit human exposure to potentially harmful rf, and to prevent Van Eck phreaking. But they look so much cooler as terminator-style masks.

Webster Chicago Wire Recorder

This is a Webster Chicago wire recorder. It was manufactured sometime between 1945 and 1955.
Wire recorders store audio by magnetizing a fine wire and storing it on a reel for playback. The wire moves by the heads at about 24 inches per second.
This wire recorder was manufactured under license from the Armour Research Foundation.
We haven't got around to turning it on yet, and we are considering encoding data into audio and eventually using a wire recorder to store pictures and other data.

I wasn't able to post for about three weeks, as the ACCRC was preparing for and attending the Linuxworld expo at the moscone center. We did the installfest, which took a lot out of me and everyone else. Anyways, the posting will continue.

Timex Sinclair 1000 and Atari 1200xl

I would have turned these two on and tested them, but there's a problem with the video setup. Anyways, here are the two of them:

Hazeltine 1510

Bumped into this recently, thought it might be interesting to post about all the terminals we have. It's a Hazeltine 1510 terminal, one of the many old terminals which reside here.
I think an old terminal such as this would make a great frontend to a project like a robot or a cluster.
