Just a quick build, adapted from some older ones…
For cars parked down the street/hill from the front of the house, waiting in line, they can see most of the lights, but can’t see our long Info Matrix under the carport, which has tune-to, song, and show information.
Kim asked me to put some kind of a Tune-To sign on the hill in that corner of the yard. She wanted me to use an old matrix from a couple of years ago, but it is very low resolution and frankly wouldn’t look good.
I had a small P10 matrix made from 3 panels that I used last year for show information in my office. The panels for it were recycled from another project I never completed.
This was replaced this year by a small touch-screen that runs off a Raspberry Pi with some custom software I wrote. It’s nothing fancy, but is easier to read at a glance than the scrolling P10 Matrix.
So- I decided to use it for the new Tune-To sign. I’m driving it using a Panel Pi-Hat attached to the back, with the whole thing wrapped in clear sign vinyl, exactly the same as our P10 columns, which have held up really-really well. I fastened it to stakes and rigged up a PSU for it, and here it is:
Well, it didn’t make it through two days of rain. Here’s the problem:
While I wrapped the panels and controller in sign vinyl similarly to the P10 Columns, the columns are partially protected under the roof, but more-importantly, they have drain channels in the bottom to allow any water that does get into them to drain out. I failed to provide any kind of drain holes at the bottom of this little tune-to sign. Water somehow got in and accumulated in the bottom (about 1/2″). This didn’t affect the controller or two of the three panels, but one of the panels stopped working. It was actually the older of the three, and a one-off with GRB signaling and color that didn’t quite match the other two. It took me about an hour to:
- Un-stake and drain out the water.
- Peel off the plastic.
- Dry the good panels out. (Towel and heat gun.)
- Replace the bad panel.
- Re-wrap. This time adding drain holes to the bottom of the vinyl!
- Update the controller.
So, it’s “good as new” again, and should survive rain and snow now. 😊
