Decentralized websites and more

“Cool idea, but to be of any use, it would need more functionality and more content” was my impression when I first looked into zeronet. Back then static web pages were all there was, and no UI support for any managing tasks. The next time I checked, probably more than half a year later, it … Continue reading »

Game modding with pen and paper

I have lots of good memories from youth camps. Some involve playing Donkey Kong and Mario Brothers while sitting on trees. Another classic video game was Asteroids. When I recently read an article in a German magazine about building an Asteroids clone with an Arduino and an OLED, lots of old memories resurfaced. The source … Continue reading »

The topic is really what made it interesting enough. FinTech is about new technology in finance. I’m sure there was innovation in the financial … Continue reading »

an exact clock for a vintage car

Since I drive my vintage XJS not too often, I disconnect the battery. This is to prevent if from going flat before I want to use it the next time. Of course it would be better to install a special charger for classic cars. But there is no outlet in the underground car park. The … Continue reading »

the infinity mirror

Lately while browsing through thinkgeek, I stumbled upon the infinite dungeon corridor. It looks cool, but they still have no affordable shipping options. That got me thinking that it should be possible to make an infinite mirror with the kids. It didn’t take long to find a recipe for how to go about it. Finding … Continue reading »

A strange kind of holiday

It all started about two weeks ago when my wife discovered water on the kitchen floor that kept coming. The plumber who came immediately, found out that two parts of the waste pipe shifted out of each other, leaving a gap open. He told us that this must have happened two or three weeks earlier. … Continue reading »

Trezor BitCoin HardwareWallet

Today I received my Trezor BitCoin HardwareWallet. When I ordered it in June 2013, the expected delivery Date was October. But as it happens all that often with BitCoin related hardware, the dates get pushed back. They offered a device with plastic case for XBT 1 and one with an alloy case for XBT 3. … Continue reading »

Smart Radios

For a couple of years I have been running mpd (music player daemon) on an Alix, connected to a stereo in the office. The Alix runs headless, but I have a variety of options to control it: gmpc on the notebook, Droid MPD client on the phone and fookebox in the browser. Over the years … Continue reading »
