Another nice build for hand based chainsaw

Posted on January 17, 2017 by robertwilkie

The author took an old chainsaw chain, cut it, pulled a few pins out to bolt it to a couple of straps, add duct tape and bam.  Done. http://www.instructables.com/id/Handpowered-Chainsaw/

A Fume Extractor with parts from a PC

Posted on January 16, 2017 by robertwilkie

OK the author not only is using a fan from a PC, but the case section from it to mount the fan. Good idea.  Cheaper than building one too.  He did 3D print out legs for it, but I think … Continue reading →

Make a cheap AC line detector

Posted on January 16, 2017 by robertwilkie

Build one for under $5.  Never realized how simple the A/C detector circuits where.  My 2 cents…I have one built into my stud finder.  So I should be OK. http://www.instructables.com/id/How-to-Make-an-AC-Line-Detector/

A ruler reloading crossbow

Make an opensource pellet cutter for filament

Posted on January 13, 2017 by robertwilkie

I like this build, the author basically feeds leftover filament, or string from bottle, into the build and its shreds the material into pellets that could then be reconverted into filament.  Me….I am thinking of an easier solution/build. http://www.instructables.com/id/3D-Printed-Open-Source-Multi-Material-CutterPellet/
