Re: Dec 2005 issue

I checked the local Borders, and Barnes and Noble, last night and they didn't have any. The B&N's computer said they had 3 in stock, but none could be found. Looks like a good issue, am looking for one. May try Fry's tomarrow in Sacramento.

Re: Radio Shack getting out of parts supply

Its too bad.

One of these days the automatic cameras that take pictures of red light runners will do the same for cars pretending they are emergency vehicles. If they don't do that already.

Re: Relatively Compact Power Generation Using Fuel

I was looking at US Army (DARPA) research projects a few months ago and ran accross a small electric generator they were trying to develop. It was to use a ceramic high speed impeller to work in a little turbine for powering electrical things in the field. In the order of hundreds of watts I think. ...

Re: "POPTRONICS IS NO LONGER IN BUSINESS"

Are you talking about that article that the Egyptian pyramid was a big electonic gadget? That was a pretty bizarre story, and of course didn't quite add up.<p>I got the impression that some non-nerd new-age son of an owner took over the magazine and was trying to "sex up" the content.<p>Is that wher...

Re: Radio Shack is creating new robotics kit

I'm trying to be optimistic, but I'm not impressed so far. The web site is animation based and loads slowly, and there is no way to bypass this. Dial up connection is very slow.<p>The mechanical animation shows two toothed wheels tied together with a red belt, the toothed wheels apparently climbing ...

Re: Older cpu fans with the round thing on the wire

Harbour Freight sells a 5watt 12v solar cell for about $35.00 on sale. Runs the larger computer power supply type fan quite well on sunny days to try to keep the car cooler. These fans don't use much power and using a solar p.v. panel acts as its own controller. Put one on a car last June and the gl...
