These are our team’s new lighted numbers we will be bringing to competitions with us. The numbers were CNC routed out of plywood and painted red.
The ‘lights’ are Oslon LEDs on PCBAs. The LEDs take 24 V input, so we use a pair of robot batteries wired in series. We ran them at the Boston regional on their “medium” setting. On “high” setting we estimate about 85,000 lumens are coming from the signs!
This was a fun project for our team to do, and was a lot of fun to finally get them lit up in the stands. I think you can ask anyone at the Boston Regional if they knew where 125 was sitting and they’d be able to tell you…
They look fantastic. It looks like you chose to sit in the back of the arena to not spoil the view of other spectators sitting behind you. I wish all teams with large signs were as thoughtful.
We knew there would be some comments when we were making the signs, but they were always just about having fun. The signs are only lit pre/post 125 matches, and during extended field delays (dance sessions).
I know our team had a lot of fun with them this weekend are looking forward to cranking them back up for the Pine Tree Regional in a week and a half.
All I could think of was, “Don’t watch the weld without eyewear!”
Seriously, this sign has retinal overload written all over it.
In a well lit dome arena like St. Louis, it will look great.
