Build your own PVC based Rubberband Machine Gun

Posted on April 27, 2015 by robertwilkie

I remember a kickstarter project to build a wooden version of this.  This is much cheaper solution thought.  Maybe $20 in materials.  This could be a fun project to build with kids, and I see a few spots where we … Continue reading →

And more on Xerox not looking too good in stock

Posted on April 27, 2015 by robertwilkie

It seems 3D systems, which bought out a bunch of Xerox’s 3D printing tech, and Xerox, both had a lousy week last week. http://www.wsobserver.com/stocks-you-should-dump-3d-systems-corporation-nyseddd-xerox-corp-nysexrx-hanesbrands-inc-nysehbi-guaranty-bancorp-nasdaqgbnk/7211784/

$5 LED lanterns

Posted on April 27, 2015 by robertwilkie

This has to be an interesting build.  The author uses PVC pipe (painted) to be a “stand” and then ping-pong balls to diffuse the light from the LED.  Nice build (I figure closer to $10 to build than $5).  Not … Continue reading →

Use a big steel bucket for a hose holder

Posted on April 27, 2015 by robertwilkie

I like this project, why?  Well the typical “hose rollers” leak after a few months.  So they are nice in rolling up the hose, but a pain if you don’t want the water leaking out with them.  So instead I … Continue reading →

3D Printed slider

Posted on April 27, 2015 by robertwilkie

Well made with PVC pipe for “sliding” on.  The author built this for DSLR cameras.  Me…this could make a good build for a simple CNC for kid projects.  Oh and I don’t think the author factored in the plastic in … Continue reading →

3D print Z-Axis for CNC

Posted on April 27, 2015 by robertwilkie

Nice build for an almost all printed Z-axis for a CNC.  Not so sure I would do this over building one from other materials.  I would be a bit worried about the flex on the plastic.  The author geared this … Continue reading →
