Salt Lake City and Bryce Canyon, Utah


The 50th annual meeting of the Biophysical Society was held in Salt Lake City, Utah, February 18-22, 2006. Here are a few pictures from Salt Lake City and Bryce Canyon which I visited afterwards.

Salt Lake City


The Temple


Looking down Main Street


The newly built library. Architecture somewhat similar to the 'promenade' concept on the Silja Serenade and Symphony ferries ('floating hotel' type ferries between Stockholm and Helsinki).


A view from the roof of the library.


The Mormon Tabernacle Choir hosts free rehearsals and performances, definitely worth a visit !

Antelope Island and the Salt Lake


The Wasatch mountains as viewed from Antelope Island.


An unlucky nail in the right rear tyre forced a quick pitstop and a change of car at Avis...

Bryce Canyon

On friday we made the 200mile trip south of SLC to see Bryce Canyon National Park.


Driving through Red Canyon on the way south


I thought I felt a definite shortness of breath when walking up hills at this altitude - or maybe it's just lack of exercise...


The beginning of Grand Canyon in the distance...

New Servos and Rails for CNC upgrade

Back in October-November Surpluscenter was 'giving away' brand new servos at 40usd/servo when the cost for new ones can be 1000+usd/servo ! So we just had to get these for our next cnc upgrade. Here are some 400 W Sanyo Denki P5 100VAC brushless servos. The bigger servo, third from the right is a 1 kW model. The catch is that these servos need an advanced servo amplifier/drive to operate. There are several amateur/open-source efforts which aim to produce such a drive cheaply or DIY:

To finance the amplifier development/purchase and the rest of the upgrade, I am selling three of the 400W servos.
