Mike,
You might like to look at model airplane radio control units. Most model airplane units can only see one frequency, but you might use two of them.
Don't know much about radio.

Eye movement is easily done with a couple of light sensors on the arm of a servo. To make this work you have to be digital. To feed the servo from a number, you need a servo node. To feed the servo node you need to subtract the input from the two sensors. The eye will follow simularity. That is, the...

Greg, All active machines can be divided into sensors and motors. Disney type machines are mostly motors, driven by a remote person or computer. Motors are actuators. There are two types of motor action. From number to velocity, or from number to position. This whole area is motor interfacing with n...

I would dive right in and go to PIC chips. There is a large assortment and they program fairly easily. http://WWW.microchip.com
Plan on spending 200 bucks.

Daniel Thanks for the comment. There was no mathematical structure to describe neurons until I invented HalTrees in 1994. Any computer, no matter how fast cannot emulate neurons for the simple reason that computers are linear, single stream machines and neurons are many inputs to one output. The com...

Yes, you could use telephone cable. Buy two 9 pin plugs or sockets as needed at Rat Shack. There are four connections. Assuming your programmer is set up as DCE side, the computer is DTE. Oops, you need ground, so you will need at least 5 wires. The computer Your programmer Pins Pins 2 Data out 2 da...

You will need the software before you can do anything. The cable might be a simple thing, but they could get you there also.
With the software you should get an assembler, a simulator and a programmer.
Sometimes you just gotta pay.

dutch, a good start at RC is RC Modeler magazine which you can find at any news stand. They have adds for servoes and radios and articles on basic RC from time to time. The basics are, the radio you hold in your hand has pots that send info to radio receivers in the model. They in turn send signals ...

Buy a faster car.

Toejam, I don't think anyone knows what a neuron does. All I know is that it is in the form of a mathematical function. Axon = f(all synapses). Everyone is measuring like mad but the poor neuron only works properly when connected to others, so I think most people are measuring nonsense. When I inven...

The dishwashing liquid used in automatic dishwashers is good for final wash of circuit boards. Not good for your hands.
What you want is something that leaves little residue.

Ian, The ADC converter needs nothing special, except that it must sample at least four times faster than the highest frequency in the audio. That is to prevent false numbers. Going back to audio is also simple. Probably, if your digital was good, you will need no filters. You can always add filters ...

Brett, with Hal algebra you can build a brain of any size. Here is the simplest. Motor = n(sensor) To make this algebra from a standard algebra, let the variables be sockets. Let cables carry the data. Cables have plugs that plug into sockets. Each operator in the language is a computer node. There ...

I need a little more information about your project. Also it would help if I knew your level and background some. Tracking people depends on whether you are counting or tracking. Tracking depends on detection and location. Counting is basic detection. If you want private, please email.<p> hlreed@hal...

Thanks for the comment. Data flow for any live machine is: Nature -> Sensors -> Brain -> Motors ->Nature Note the feedback loop. My sensors write data streams. My motors read data streams. My HalTrees can match any neuron in form. A neuron is Axon = f(all synapses) A HalTree is Output = f(all inputs...
