One serious homemade filter for a rain barrel

Posted on June 16, 2015 by robertwilkie

When I first saw this I thought, OK cool someone converted a 5 gal bucket into a simple rain catcher.  But…the author didn’t stop there, its got about 1/2 full of different materials to “filter” the water. http://www.instructables.com/id/Raincatcher/

Another nice swamp cooler build

Posted on November 17, 2014 by robertwilkie

Another nice build.  And yes I know its winter, but I am already thinking about summer.  My 2 cents, I think I would cheap it out a bit more by using a different top to pull air in.  I do … Continue reading →

Nice simple peristaltic pump you can print out

Posted on September 18, 2014 by robertwilkie

Nice simple pump.  A cheaper solution can be found at harbor frieght, for garden hoses and a drill thought, and not really food safe as this one. http://tim.cexx.org/?p=1282 http://hackaday.com/2014/09/16/a-3d-printed-peristaltic-pump/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+hackaday%2FLgoM+%28Hack+a+Day%29

Waterbottle to supersoaker

Posted on September 5, 2014 by robertwilkie

Looks like I missed this kickstarter project, it converts a waterbottle into a pump action supersoaker.  Neat idea, thought a bit pricy when I could just cut a slot in the bottle and squeeze water out.  Still worth keepin and … Continue reading →
