Xylobands Answered

Anyone  got any theories on how the xylobands work?

Especially at the £3 a piece mark?




according to the Wikipedia entry on them they are controlled by a combination of software to control the lighting and color, and a radio transmitter with an effective range of up to 900 meters.

RF in the Sub Ghz band.The latest version use the Slilicon Labs 4362 RF receiver chip.

Probably just RFID technology - they'll just send out a signal to trigger pre-programmed stuff.

Three quid each? Easy - buy in bulk (how many thousands of fans at how many shows?). RFID technology is cheap, LEDs are cheap, silicon wrist bands are cheap, watch cells are cheap.

The product website says they cannot be activated again, but I'd bet that a few minutes with a sharp knife and a soldering iron would fix that.

Is RFID the right technology though? The stadiums are 100s of metres long?

Or some other simple distance trigger - I found a reference on Hack-a-Day that said the band had a programmable microcontroller in it - they could be triggered by a radio beep, or even a sound signal.
