LaTeX: x11names resorted

I like the color palette which the xcolor package offers under the option x11names, but I find the list of colors in the xcolor manual a bit confusing. The colors are sorted by names and not shades – so today I made my own little table.

An USBasp in a new design II

Most of the time I design and debug my AVR projects on solderless breadboards nowadays. And for that I have been using some different types of programmers by now: starting with the good old STK500, to different versions of USBasp clones from Chinese sellers on eBay.

In order to connect the programmers to the […]

An USBasp in a new design

Just a small teaser: today I received my circuit boards from PCBgogo – a layout which I just had sent to the Chinese manufacturer last Sunday.

The finished circuit board from China.

It is a USBasp, which can be placed on a breadboard and at the same time supplies the power rails on […]

Nerd or not?

Today there was a geocaching event celebrating Nerd Day. I must admit that I wasn’t aware of the significance of today’s date, but I also knew that I can probably be considered being a nerd.

The small birds only had a few days of life but they somehow enriched my days.

…they just had a few days […]

BirdCam – feeding in slow-motion

Because there was a problem with the Raspberry Pi again today, I took the opportunity to film my fieldfares live for a short while. In this slow-motion video you can see how first the female arrives at the nest with a fresh worm. A short while later also the male arrives with a beak […]

Hatching time

“I’m hungry!”

Ten days Mrs Fieldfare has been sitting in her nest – today was the big day: until late afternoon three eggs had hatched. Now also Mr Fieldfare has to show some effort who has not been much around the nest lately.

This is […]

BirdCam v4

It took four attempts to finally get a suitable webcam to observe the bird’s nest outside my office window. Most cheap webcams, even those which show off with true 720p HD resolution simply cannot cope with the different outdoor lighting conditions over a full day.

After a lot of testing and research on the […]
