I’ve been testing some flashing red LEDs with CR2032 batteries to see how long they’ll last. My first test confirmed that they’ll definitely go 48 hours, which is good, because they’ll have to last the duration of Maker Faire.
Here are my completely unscientific notes taken this week after starting a new test on Monday night.
| Day/Time | Status |
|---|---|
| Monday 11pm | Extremely Bright |
| Tuesday 11pm | Extremely Bright |
| Wednesday 10pm | Very Bright |
| Thursday 11pm | Somewhat Bright |
| Friday 6pm | Not Quite Bright |
| Saturday 6pm | Dim |
| Sunday 6pm | Very Dim |
I think we can expect three solid days of bright LEDs, and maybe another day or two of acceptably bright LEDs. Working backwards, this means that if we want the LEDs still going strong by 6pm on Sunday, we need to start getting them in place by Thursday night.
Hmmm, Thursday night is when I teach class. Perhaps I can just make this into a group project for my class, or maybe DECODE can lend a hand…
