Redone hippie jeans similar to those my parents are wearing in an old photo when they were young. For historical correctness, I also wear the red sweater which my mum has knit for my dad back then.

RNA sonification

We made an interactive browser for RNA secondary structures, which allows to browse the structures by a sonification of their abstract shapes.

cancer database

linse — Wed, 10 Mar 2010 18:20:40 +0000

For a medical professor in cancer research, we set up a searchable online database. The database holds cancer related gene expression data collected from different studies. I implemented two different search modes, which search either for a probe or for a gene expression scenario. The list of search results includes links to the biological protein databases at the NCBI and Uniprot, as well as links to PubMed, a biomedical publication database.

The structure diagram of the database.

Probe search for a probe identified by the protein name “keratin”.

The search result for “keratin”.

Expression profile search: a logical search that is a chain of simple search queries connected by AND or OR.

solderin’ skaters / Tilt’n'Roll

linse — Thu, 04 Feb 2010 10:50:51 +0000

With a group of nine students we were one of the winning teams of the Nokia push n900 challenge with our idea of using a real skateboard to control a game.
We equipped the board with custom truck spacers, which are able to send sensor data from the board to a smartphone via bluetooth. On the smartphone, a trick detector is running, which detects skate tricks and sends an according event to the game, which also runs on the smartphone. The skater may earn points by performing skate tricks, and is rewarded not only by the possibility to enter a high score, but also by sound feedback and change of background music, and the possibility to report performed tricks via a microblogging service such as twitter.

Our hack was presented at the Nokia push party, on hackaday.com and at the decode exhibition in the Victoria&Albert museum in London. It also resulted in a scientific publication.

As you can see, I am part of the software team.

My outdoor cutlery.

I made the two spoons in the center, the one with the exaggerated shape is made of linden wood, and the rogue spoon is made of olive wood.

TV-B-Gone hat

linse — Wed, 31 Dec 2008 10:45:49 +0000

The TV-B-Gone is a tiny universal remote control that switches off most TVs.
I built a European version of the TV-B-Gone and concealed it in a wooly hat for discreet usage.
