Good write-up on how to convert a picture for laser engraving

Posted on December 8, 2016 by robertwilkie

The video in this is fun to watch.  Never worked with lasers myself (yet).  But the smoke coming from it is pretty intense.  I would be a bit worried about burning the place down. http://www.instructables.com/id/How-to-Laser-Engraving-Photo/

Posted on December 7, 2016 by robertwilkie

I like the idea of adding a board the the monitor for sticky notes but…not so sure how long “tape” will hold it on there.  A more permanent solution would be ideal. http://www.instructables.com/id/Transparent-Monitor-Noticeboard/?ALLSTEPS

Interesting CNC plotter

Posted on December 6, 2016 by robertwilkie

Interesting build.  It is belt driven and is a basic plotter concept.  The steppers used are pretty cheap kind (which surpised me considering the work that went into this).  But whatever works right? http://www.instructables.com/id/Drawing-Plotter/

Cool simple pressure chamber

Posted on December 5, 2016 by robertwilkie

Basically add an old inner tube value to the top of a soda bottle.  Good for a pressure chamber at low pressure.  Just keep in mind that too much and the bottle will go boom. http://www.instructables.com/id/DIY-Pressure-Chamber/
