Use cheap cutting boards to make signs

Posted on April 22, 2016 by robertwilkie

I have actually thought about doing this myself.  The cutting boards look nice, and you can pop the board into a CNC to cut out a sign.  And the boards can be cheaper than getting plank from Home Depot. http://www.ikeahackers.net/2016/04/diy-door-sign-ikea-chopping-board.html?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+Ikeahacker+%28ikeahacker%29

Make your own remote spray can trigger

Posted on April 18, 2016 by robertwilkie

OK this is cool, a simple build to print out to trigger a spray can.  Only issue I can see is the clip that attaches to it could wear out. http://www.thingiverse.com/thing:1496622
