Interesting TAP handle tech question \ quest.
I recently bought a Beer tap handle and noticed that it had an insert that had some LEDs on it. Cool. The problem is that the LEDs don't light (beyond a tiny SMD red LED heartbeat). I found a small button that when depressed seems to trigger a test. Bright white LEDs on the top and bottom flash to illumnnate the top of the tap (either a clear baseball or FIFA tap topper) as well as the body. It's hollow plastic so it briefly glows.
The problem is that I can't figure out how to light the things beyond the test (for which you have to remove it from the handle).
The guy who sold it to me said they've sold lots like this and could never figure it out. I figured light sensor? nope. Tilt sensor so it'll flash when you pour a beer. Nope.
I broke out my loupe and noticed a funky thing on the circuit board that looked like it had an antenna. It was an Anaren A1101R09A.
This thing is a radio tranceiver! That tells me there was a remote with it that was lost in the few days after they bar got their new tap handle.
Does that sound right? If so I was wondering where I could get or build another. I could put together some other LED solution, but I'd love to get this to work.
HEre's a pic of the tap handle and the insert laying on it's side. The right side is the up side with the transceiver. It's blue if you look closely.
Not sure I'll get a solution, but there's some clever people here, so you never know.
Thanks for reading.
