Thanks for that teacher :+1: that’s cleared that up , I thought it was probly a joke as I could clearly see through it ,tinterweb & forum talk can be a bit confusing at times.
What I was trying to say is that the material I posted in the pic, in the same thickness as the spacer board in the D18, would probably be see through. As you can see in the pic I posted, the table is clearly visible through the thinner sheets.
Basically I put an extra Attiny85 in there, who's sole purpose is to drive a single WS2812B emitter.
It was originally supposed to look like this:
It was great because the positive and negative of the Attiny85 matched the WS2812B perfectly, according to the schematic, which was wrong. The Emitters poles were actually the opposite, so I had to flip or around and run the data line over the back. Much less elegant:
But it worked. I did clean this one up a bit more before installing it, but you get the idea.
The speed of the rainbow effect can be sped or slowed by setting parameters at compile time. There are other effects in the code I found, too.
I have no idea of the current draw, I suspect it is somewhat high, because the Attiny85 is running at 8mhz nonstop to drive the signal fast enough to control the WS2812B, but I don't have anything sensitive enough to measure it.
The schematic was just wrong, the data in and out pins were in the right place, but the notch in the corner should’ve been positive but it was negative, and negative was positive.
I’m embarrassed to say it took me more than I couple minutes to figure it out. I thought I was damaging them when removing them from the strip I was harvesting the from.
Thanks, yeah I like it. I figured if I was only gonna have one single emitter, then I should do something fancy with it. There’s juuust enough room to get it all in there.
Turbo output really depends on a lot of factors, some of which aren’t even part of the light. Basically just think of it as a really bright burst mode, where the actual brightness level doesn’t really matter. It’s like turning on about 10 to 20 common light bulbs all at once, and focusing the light into a beam. But it doesn’t really matter if it’s 10 or 12 or 17 or 20.
