Pneumatic Guillotine Lid Installed

After determining that operating the LN2 sample dewar without a lid was going to be problematic with regards to ice accumulation in the liquid nitrogen I decided to design and install a pneumatically operated guillotine lid. Here is a nice aerial shot of the closed lid. hit the jump for details and more pics…

Structure of a Thermus thermophilus 70S ribosome functional complex at 3.7 Å resolution

In 2006 the Noller lab from the University of California, Santa Cruz solved the structure of the Thermus thermophilus 70S ribosome at 3.7Å resolution. This work was supported by data collected at both 12.3.1 and has been recently highlighted in the ALS news. The original publication was in CELL. Korostelev A, Trakhanov S, Laurberg M,…

Crawl, Walk, Run

Today DOMO mounted its first pin from the sample dewar that was filled with liquid nitrogen. This video is pretty large so unless you are on a fast connection or have alot of time to waste trust me DOMO is finally crawling.

DOMO Lives!

After two days of code wrangling, two snapped electrical cables, one crash into the goniometer, and several reconfigurations of the force sensor and gripper arms DOMO is alive. On Friday afternoon DOMO mounted its first sample successfully. There is still much work that needs to be done and many bugs to be ironed out, but…

Domo Arigato, Mr Roboto

The new PX automated sample mounting robot shall henceforth be known as “DOMO” as in Domo Arigato. Mr Roboto. It’s short and catchy, but isn’t really an acronym for anything… yet DOMO Doer Of Mechanized Operations? or Dolt whO follows My Orders? I think beer will be given to the person who comes up with…

Sample Dewar take one

Being the brave souls that we are we thought we would attempt to make a sample dewar without a lid. Our main concern is ice. We are concerned with the build up of ice around the rim of the dewar, but more important is the prevention of ice accumulating in the liquid nitrogen in the…

the Sample Dewar actually fits

The Aluminum sample dewar enclosure actually fits. I guess you have to trust the 3D CAD drawings after all.
