4 Months – Longest Day, longest continual run
An update video of the Pressure Cell, which began running on Feb 20th 2013.
Also of the ‘blue LED’ salts cell which has run, on and off, since November of 2011.
Sorry about the bad lighting, these 2 sit on a dresser in the bedroom.
Here’s the How To build video of the Pressure Cell: http://www.youtube.com/watch?v=edLjw09nYpY
