Hi guys, been lurking around here lately, but now I have something to show!
I’ve been working a Bluetooth LE controllable LED stick for light painting. Currently powered by a Teensy 2++, 46 x LPD8806 LEDs, and an Adafruit BTLE breakout board. Finding FastLED was critical to being able to actually do these animations, especially HSV and the fast math functions.
Here’s a test video of the Bluetooth iOS link. It shows an iOS app created for this project controlling the LEDs.
I’m excited for RFduino support, as I’m hoping the next prototype will utilize it. An Arduino, plus a BTLE breakout board is pretty bulky. An RFduino would allow miniaturization of those two things into a tiny SMD part. (Not nagging, I know it’s coming)
So a huge THANK YOU to the maintainers and contributors of this awesome project. I’m not sure I would have got this far without you.
@marmil Lessons learned? Mechanical engineering is hard! I’m a software guy so the hardest stuff was the enclosure, wiring, fitting all the components and securing it all so it doesn’t break if you drop it. It was much harder than I anticipated. And I still have a ways to go there. My next prototype with the RFduino should handle all that better.
@Synthetech Potentially, I wrote it in Swift, so it’s not directly portable. If I was going commercial with this I probably would have to figure it out. Figuring out a binary protocol to transmit data a maximum of 20 bytes at a time took some frustrating late night learning…
