How to build your own soccer/football referee communication system?
An example of this is here: http://www.crescentcomms.com/
A similar system is offered specifically for dental offices: here (NOTE: actual that website shows a lot of interesting equipment)
The problems associated with this system are:
-Too many wires
-Too many pieces of equipment
-Too heavy to wear (a transmitter is strapped to your shorts as you run around)
-Uncomfortable to use as you are running and sweating
People can build their own cheaper systems by buying 2-way walkie talkies, headsets, batteries, arm straps, etc. off the shelves. But it retains all the drawbacks.
What I really envision are the following:
-Secure communication (i.e. set channel/frequency) for at least 4 referees
-Open communication (i.e. no need to push to talk)
-Each referee wears a bluetooth headset like this one made by Platronics
-Adjustable ear pieces as needed
-Need to work for at least three hours straight at one time
-Ideally powered by small lithium batteries (like those used for watches)
-Ideally power source should be rechargeable or somehow be able to plug into USB or outlet for recharging
As you can see, I really would like to see something built that can eliminate the wires, the weight, and discomfort. Keep it super simple to use and equip.
If anyone has suggestions, please offer them.
