Bike odometer

I wanted to get a bike odometer... Well there was still my old galaxy 3 lying around... It's even water resistant.
Holder for 1€ from China.

First GPS fix with a new firmware (OMA)

Digihud as the odometer.(using GPS) It also fearures a HUD display overlaying other software.

And since I don't know where to stop:
For navigation be on road.

All apps need to be loaded via apk since the device is way too old for play store.

Next step: power over the generator from the bike with a buffer battery.

Door closer

So our cat always wants to walk in... But I wanna have the door closed... First prototype... In the end the rope is white and all the stuff should be on the left side of the door. Can easily be adjusted by adding or removing water.
