Step 5See it in action
Real world testing. Yes we had some snow, but that was before xmas. Now we have some snow again. But, as usual, during the xmas holidays and new year celebrations all we had was rain. Please ignore me groaning at about mid-video, I'm getting old so squatting gets a bit hard.
Finally some slightly improved effects.
Mission accomplished. Geeky taillights, and illegal where I live too ;-) I'm pretty sure I won't be ignored by sleepy or ignorant motorists anymore. By tuning the timings a bit, you can create pretty annoying effects that are good eye catchers. Especially at night.
As there are 4 GPIO/ADC pins on the boards (2 may be used for building a small I2C network), it should be easy to hook up a push button to trigger all sorts of effects. Hooking up a CdSe photo resistor would work as well.
Total material cost is about 50$. The biggest chunk went into the printed circuit boards. Low volume order penalty as usual.
In analogy to a once widely spread TV commercial for a cell phone company in the US, let me ask you this:
"Can you SEE me now? - Good."

BTW, it's the same thing as staring into rear fog lights. You get blinded as well.
I'm thinking of having a small series of the circuit boards made, but that will take some more time. The next prototype is still a several weeks away.
