Hmm... so I might guess that something like this: http://www.elcomresearch.com/shop/item.aspx?itemid=11 ... is operating in a legal gray zone, at least in the U.S. (they're in Greece)? They're using off-the-shelf GPS and Bluetooth modules in there, but I'm almost 100% certain (from e-mails with the main designer) that they didn't go through a formal certification process... ---Joel

Not necessarily. If you use a pre-certed module with its native antenna and just place that pre-certed stuff inside a plastic shroud you can be ok. > ...

I have one transmitter in a samll black PVC box to control the 'aan uit' light system (hacked). ftp://panteltje.com/pub/cracking_klik_aan_klik_uit_img_1003.jpg The small PCB is a trasnmitter.... You can key it simply with the power, it has a separate digital input too. I drive it directly from RTS on the serial port, enough power! This is the tranmitter in the box: ftp://panteltje.com/pub/lremote_transmitter_img_1004.jpg the box is also from conrad, adn also very cheap, and small. I bought a bunch of these boxes for small pic projects like this: ftp://panteltje.com/pub/LED_control_box_img_1162.jpg That black thing on the side is a connector shell with a LDR photocell in it.. >Frank Buss, fb(a)frank-buss.de >http://www.frank-buss.de, http://www.it4-systems.de >
