Of course neither me nor any of my colleagues had an appropriate protection to view the upcoming solar eclipse. So I had to ‘hack’ together a device to still be able to watch the eclipse pass in a safe manner.
Solar Eclipse (Munich, Germany, 2015.03.20 10:40 CET) viewed though a simple (5 minute hack) pinhole camera:
The camera was built from an old rolled conference poster, some adhesive tape, plastic foil, and a cardboard box. I think it is self-explanatory:
One side was covered with opaque foil, only a tiny pin hole (< 1 mm) let light through. The other side was simple plastic foil (from my lunch). The box acted as a shield to protect from accidentally looking into the sun.
It’s a mirror image, by the way.
Just for fun: Made jelly for my little ones today. I was so fascinated by the wobbling of the jelly that I used it as a test candidate for my new Canon EOS 70D camera… the result is a somewhat senseless test video. So clear the stage for the Jellydance:
And by the way: strictly speaking, jelly is mostly stiff sugar water. Five minutes after the video was shot all jelly was gone…
Christmas time… time for colorful lighting. 🙂
The chicken we had for lunch last Sunday protected itself against the NSA but not against five hungry mouths…
Okay, this already happened a while ago but I just stumbled across it again caused a big fat smile. 😀
A few years ago Apple (AppleCare to be exact) sent me a very special tool along with my warranty replacement iPhone 3GS: a paper clip. What should I say: a perfect replacement. 🙂
I’m not sure what to make of this: last evening I played around with a new hardware device (a TP-Link TL-MR3020 router, but that’s not the point). I was leaving the room and just as I turned off the lights I noticed a green spot on my desk. The USB power supply of the device emitted a green phosphorescent glow (Wikipedia).
I’m not sure why the manufacturer used a phosphorescent material for the case of the power supply, but the effect is quite impressive (creepy) and lasts for some minutes. By the way, it’s a Huntkey Switching Power Adapter model HKA00605010-3B.
I was lucky to be in the first group of people to receive two TI Stellaris Launchpad LM4F120 Evaluation Kits. Hurray! 🙂
I bought both kits for 9,98 US $ directly from TI. Here some photos from the unboxing. I will update this post as soon as I get a development environment up and running. For everyone who can’t wait: there is a nice “Getting Started” page from TI with video tutorials and tons of information.
P.S. I like the comment of the Stellaris MCU Team in the box: “Happy Coding!” 😉
