Arrived in Hannover where I originally was supposed to switch trains. Arrived 30 minutes late and missed my connection.

But the other train is also delayed by more than 20 minutes, so I can make my connection after all.

🤷🏻‍♂️

Did not end up buying the flamethrower, at least not today. But I did find a fake Lego robot arm that I can probably control directly with Bluetooth or hook up to an Espruino Jolt.

And I did not look at the forecast and brought sweaters… 🥵

If I remember correctly, it is a pun on the term full-stack developer.

I just love seeing Vasilis play around with clocks. And after his post about building a gradient clock, I found the circular display and I just could not resist buying it, just to play around with it.

This is the screen I am going to be using:

You can basically bolt on a Raspberry Pi to the back and add a Sensor hat for the accelerometer. Got basically everything figured out except for how to get the sensor readings into the browser running in Kiosk mode.

So did I spend this Sunday building a gravity simulation for the hands of the clock? Kind of... yeah. Eventually this will run on an Pi with a 5" circular screen and a sensor hat.

Is it useful? No. But it was fun and it is just amazing to see what the web platform is capable of.
