Today was the first performance where the lit up flags were used. I have to admit, they performed better than I had expected. Despite having someone literally sit on our flag bags, nothing was broken and they worked flawlessly. There are still bits and pieces of the show that needs cleaning up, but overall the audience was very impressed. Can’t wait to see what will happen at state finals!
And this is what they look like in the dark:
After some research, I settled on the ASMT-UGB5 series green LED from Avago Technologies. They’re small at 3.2mm x 2.8mm and give out a whopping 1,800 mcd, or millicandelas. I designed a grid on a 50mm x 50mm board that I would cut out into separate pieces. Each LED needed its own resistor. In total, for 22 flags, that ended up being 264 LEDs pared with 264 resistors.
Here’s a short video of the assembly and cutting process:
And we have lit up flags! This is a short test of the flag, testing handling and balance. The kids certainly liked it and are looking forward to getting the audience roaring at the next competition!
I received a request to add some flair to the flags for this year’s Winter Guard show, “Radioactive“. What do they mean with flair? What else, LEDs! I was tasked with putting LEDs on the symbol on the flag. All they want is to light up the corners which translates to needing 12 high brightness green LEDs. These flags will be used in a brightly lit gymnasium, so I need to find some very bright LEDs. Guess it’s time to do some research. I’ll need to figure out what kind of LEDs I can use that are very small, and yet very bright. And then there’s the issue of batteries. Where in the world am I going to put them. Oy vey.
