Convert your 3D printer to be portable

Nice build where the author converts his little printer to run off a battery.  Down side…well the driver (typically a computer) will need a battery too and STAY ON while the print is working.  Which could be hours.  I also … Continue reading

Add this to the list of stuff I want to print out

I watched the video on this one, its pretty neat, the cylinder seems to fly thru the air better than a football.  And yes, this is on my list to print. http://3dprint.com/73490/vortex-tubular-wing-model/

Use an encoder to tell if you have a print jam

Gotta say this is a good idea, the author uses an ATiny and a wheel to tell if the filament is mov ing or not, to detect jams in the print head. http://hackaday.com/2015/06/16/prevent-failed-prints-with-a-filament-speed-sensor/

One serious homemade filter for a rain barrel

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/

Convert a bike wheel into windpower

I have seen builds like this before, but not one that is written up.  Its a nice build thought a bit more work than I would have done, and I think I would have done a different way of putting … Continue reading

Autopilot R/C boat

Interesting build where the author built an his own autopilot based boat.  Using homebuilt arduinos and GPS.  Pretty interesting build. http://hackaday.com/2015/06/01/simple-autonomy-with-an-rc-boat/
