Cyclabile is an experiment about showing a moving bike lane on the road: the image moves according to the bike movement, producing the effect of riding on an actual bike lane, even when there isn't one.

The effectiveness of projecting an image on the paving instead of using a traditional light can be argued, of course.

For now the project purpose is more about having some fun and making a statement (there should be more bike lanes) rather than building an actual usable product.

I had to wire up a simple navigation keypad to a BeagleBone Black for a prototype, and I used the gpio-keys driver configured via a device tree overlay.

You know what they say that constraints drive creativity, I think this post is just another little example of that.

Usually I do not put time constraints to my hobby projects, but I make sure to have some other kind of constraints, like keeping the cost low and trying to reuse stuff that I already have.

In this case I needed a way to measure the angle and speed of a rotating object for some of my projects, and I wanted a rotary encoder that was inexpensive, but precise enough to work at very low speeds.

Someone came to me with a broken GoPro Hero 3 White which wasn't turning on anymore, asking if there was a cheap way to fix it.

After tearing it down, a quick inspection revealed that the two flat-flex cables (the Shutter button one and the Power/Mode+LCD one) were both damaged, so neither the buttons or the LCD were working.

However, making contacts on the PCB traces of the Power button resulted in some reaction from the camera, so I knew there was still a chance.
