@Jon - still confused about costs and your demo. It seems you needed two systems for demo, one to send, the other to receive. each system consisted of four boards. therefore, the cost of each system would be $150?
Sorry for the confusion. The $300 kit includes two MCU cards, two wireless PICtail cards, two LCD cards, and two serial-port cards. Also, 2 USB cables, and 2 RS-232 cables. You don't need anything else. If you want to add additional nodes to a network, you could but an extra PIC18 Wireless Development Board and an extra MRF24J40 PICtail for each extra node. I assume any extra nodes would not need an LCD or a serial card. MRF24J40 PICtail card, $US 25. I could not quickly find the "8-bit Wireless Development Board" so contact the company for a price on this board.

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
