Fresh hacks every day
[dev_dsp] wanted to try his hand at creating a purely analog implementation of multiple synchronizing fireflies powered by a single battery and built from off-the shelf, through-hole components on inexpensive protoboard. In theory, even your local Radio Shack should still carry all of this stuff. He was obviously inspired by [alex]'s fireflies that we've covered in the past, but he wanted to see … [Read more...]
[Alex] of tinkerlog created a set of 64 RGB fireflies that synchronize to blink all at once. We covered the kit earlier, but he has assembled a set of 64. Each firefly is independently controlled by an ATtiny13 that reads a phototransistor and lights up an RGB LED. The fireflies are programmed to blink a certain rate, but blink faster if they detect other blinks. After a few cycles, the fireflies … [Read more...]
As many of you have mentioned, there are a lot of projects that are built with their own microprocessors, and are simply overkill. Here's a reminder that we can do some pretty fun stuff light synchronized light shows without going overboard. This light show is controlled directly via the printer port on a computer. Sure you can't un plug it and run it free standing, but you can build it for … [Read more...]
