I just posted an article on my website about my barndoor tracker, a low-tech camera mount that cancels out the rotation of the earth to allow long exposure astrophotography. http://www.monaslab.com/Astrophotography.html

Hi all, I have a website with a couple of goofy experiments... an easy way to send an audio signal over a laser pointer beam, and also a barometer made from a condom and a cocktail glass. A couple of days ago, I posted a video of a French gentleman hand building his own radio vacuum tubes. Very interesting. thx! http://www.monaslab.com
