Memristor minds: The future of artificial intelligence - tech - 08 July 2009 - New Scientist

mike — Tue, 14 Jul 2009 16:14:01 GMT

An interesting article about the discovery of a new type of electrical device. Based on the equations relating charge and magnetism, Leon Chua deduced that the mathematics of electric circuits was missing an element (one that directly relates charge to magnetic flux) - he dubbed the missing element a memristor.

Now scientists believe they have found a physical device that has this effect ... at nanoscales. The device could have some amazing applications for computation.

Home Technologies: Protect your equpment with this great cooling fan

mike — Mon, 03 Dec 2007 22:56:07 GMT

What product am I excited about this year? My Tivo Series 3? My new BlueRay player? No. It's a tiny little cooling fan from Middle Atlantic. When I first had equipment installed in my living room, we had it all nicely hidden away in a built-in cabinet. DVR's (e.g. Tivo), Satellite receivers, and DVD players can all generate a significant amount of heat. When placed in an enclosed cabinet they are unable to stay cool enough to prevent the heat from damaging the components.

After frying a couple of pieces of equipment, we had Home Technologies install the CAB-COOL fan in the side of the cabinet. What I love about it is that it has an integrated thermostat that lets it spin slower and keep the fan noise to a minimum. Installation is simple and self-contained and our equipment now stays nice and cool.

CharliePlexing : How to drive a lot of LEDs from a few microcontroller pins.

mike — Mon, 09 Apr 2007 17:59:39 GMT

This seems pretty clever - controlling N*(N-1) LED's from just N available output pins from a micro-controller (as opposed to N led's for direct drive, or (N-A)*A for row/column addressing).

However, with a decoder, seems like you can get exponentially higher than this: 2^N is possible for a clocked circuit which can latch the LED address (but the chip count goes up).

So for 5 pins:
Direct: 5 LED's
Row/Column: 6 LED's
CharilePlexing: 20 LED's
Decoder: 32 LED's

Finally, you can can an "infinite" number of LED's driven through a serial interface. So - with "1 pin" you should be able to drive a clocked shift register to control a very large number of LED's (e.g., with 1 100 element shift register, full the registered rapidly in burst mode, and then pause to let a capacitor charge next to each LED).

I wonder if you can buy 3-wire modular LED's with built-in shift register and capacitors so you can hook these up like fully controllable "Christmas tree" lights.
