Testing a multitouch interface to a 2-axis microscope stage powered by cheap servo motors, controlled by an arduino, processing, and TUIO events from an iPhone. My dream is to be able to put my fingers on giant microbes and swipe them around. Based on diybio.org/ucam. ucam development 25 Feb 2010 ...

I want to make an example "BioWeatherMap" based on existing metagenomic data, so I'm looking for a dataset of 16s ribosomal dna (rDNA) sampled from tens or hundreds of environmental locations. First I'd start by creating a simple map rom the basic data (sequences + location) - something like ...

Possible solution: Use gel electrophoresis to separate the DNAs. Temperature Gradient Gel Electrophoresis (TGGE) and Denaturing Gradient Gel Electrophoresis (DGGE) DGGE of small ribosomal subunit coding genes was first described by Gerard Muyzer, while he was Post-doc at Leiden University, and has become a widely used technique in microbial ecology. ...

The BioWeatherMap project, led by DIYbio member Jason Bobe, is developing a ~$5 kit that will let users identify thousands of the microbes present in or on a given sample or surface. The kit helps the user prepare an arbitrary sample for direct DNA sequencing. In the pilot program, hundreds ...
