Raspberry Pi B+ Pinout Leaf

I'm currently working on a little project involving a Raspberry Pi and some stuff connected to it's General Purpose IOs.

Looking up the pinout scheme every time again gets tiring fast. A good solution is the Raspberry Leaf - a simple sheet of paper that slips over the pins and labels them. Unfortunately I couldn't find one that:

  1. shows all 40 pins of a Raspberry Pi B+
  2. shows the WiringPi numbering scheme

So I set down and made one in Inkscape. The result can be found in this Github Repository.

Games I liked in 2014

It's 2015 for a while now. Time to look back on the last year. I played quite a few (computer) games, so why not have a list of my favorites.

Please note, that they are listed here in no particular order. They are all available on steam. Oh and I realize that not all of them came out in 2014. But I played them in 2014 - that's what counts.

Agenda Watch Face for Android Wear

Of course the first thing I had to do to my new watch is customize it. Over the weekend I learned how to build my own watch face in WatchMaker2). The result is shown here:

Most of the information is only shown in active mode (pictured left). I went for a white background because I assume it will be much better to read in outside. Thanks to the ugly Berlin Winter weather I had no way to test that hypothesis though ;-). Dimmed mode (pictured right) uses a black background of course and fewer info.

Most important to me besides the current time are my upcoming agenda items. The watch face shows them in two ways. One is a simple list of the next three appointments. The other is a representation of their length on the border of the watch.

Getting these border graphs right was the hardest part. Since appointments happen on a 24 hour day, but the circle only represents 12 hours, I had to come up with some logic to decide when there's space for the next afternoon appointment even though it's still before twelve. Took a while, but now seems to work just fine3).

Another problem I encountered in dimmed mode. I wanted to have the border graphs in dimmed mode, too. It worked just fine in Watchmaker, but once on the actual device I noticed the watch being off-center and cutting pixels. A reddit post later I found the reason: an Anti-Burn Screensaver mechanism in Android Wear.

The watch face compensates for that behavior by moving the graphs a few pixels towards the center when the display is dimmed.

The watch face is available for download from FaceRepo.

New Gadget: LG Watch R

As you may know I'm eyeing the smart watch market for some time now and I finally decided to buy one.

My LG Watch R arrived yesterday, so there isn't that much insight to share. But I'll do it anyway ;-)
