Some more Interesting hardware

[fixstuff]

I found a new piece of hardware yesterday, that I thought others in the forum may find of interest. I remember an XMOS-based PI detector that was done as an earlier project on the forum, so seeing this made me think of that.

XMOS has a new StartKIT that is an 8 core XMOS chip on a developer board with a Raspberry PI GPIO interface header.

With a cheap LCD, the Raspberry Pi and this board, you could design a "slice" board that plugs into the board's slice port - this board could have all of the metal detector related circuitry. It appeals to me because it eliminates the need for the JTAG board needed with the old XMOS developer boards.

The startKIT is $15. Couple that with a $35 RPi, and a custom slice board, and you could have a nice metal detector I'd imagine.

Using the Audio Slice board, perhaps utilizing the PC Sound Card Based metal detector interface board such as Aziz's may be viable..

there are two problems with that, the raspberry ip is battery hungry, and from what i understand it also has io issues.

Well, I'm thinking more along the lines of a beltpack or vehicle mounted control box. I've used the Pi quite a bit, and I would plan on utilizing the off-board microprocessor of the XMOS or other CPU, versus rely on the pure I/O of the Pi. However, using the Pi as just a supervisor and GUI controller, I think it would be fine.

i see why not give it a go then, for a larger unit as a control unit might be worth exploring.
my comment before was relating to using the rasp pi as a detector its self, the only way to know is to build it!
