Infrared voting system?
I'm putting together a talent show and would like audience members to
vote for performers using keypads. I think I need a bunch of infrared transmitters/keypads, a receiver, a computer, and some software. Does anyone have an idea where I can get the keypads and put together such a system inexpensively? Thanks for any info. |

Either RF or IR is likely to be a problem if 10 or 50 people all push
the "vote" button at the same time. There are ways to enable this, but they are likely to be complex and costly. Bill ------------------- NSM wrote: "Steve" wrote in message ups.com...

Yes, this product has already been developed and works well for
instance at: estruction.com and educue.com. I would prefer to develop my own system to keep the cost down. Heterodyning! That sounds good. Do you think the transmitters and receivers on this website would do it for me?http://www.automicro.com.tw Which ones should I order as samples? Thanks again for any info.
