DIY camping lantern

Posted on August 30, 2016 by robertwilkie

I am surprised this isn’t brighter with the # of LED’s the author has.  Basically its two containers, an inner one to hold the battery and wrap the LEDs on, and an outer one to protect it.  Nice build but….I … Continue reading →

Pretty cool and small Hydrogen generator

Posted on August 29, 2016 by robertwilkie

This is a nice simple build for water to hydrogen converter.  With the exception of using razor blades, would be a good kid project.   Only which the author did steps written out instead of a video. http://www.instructables.com/id/How-to-Make-Hydrogen-Generator/

Make your own plastic grinder

Posted on August 29, 2016 by robertwilkie

Neat build for a grinder for plastic to pellets (for 3D printing.  But….I would do the planer approach (much easier) and it took the author 40+ hours to build this one. http://www.instructables.com/id/3D-Printer-Part-Recycling-Grinder/

Posted on August 29, 2016 by robertwilkie

Cool build with elastic band and a al. sheet with holes in it (where heck you get that I don’t know).  My 2 cents, I would put something around the edges of the board to keep it from ripping the … Continue reading →

Nice storage rack for shovels on wheels

Posted on August 26, 2016 by robertwilkie

Now the author built this to be a swing out shelf for the shovels.  I am thinking it would be better to use 4 casters and have it fully portable. http://www.instructables.com/id/Long-Handled-Swinging-Tool-Rack/

Simple way to get an ESP8266 on a breadboard

Posted on August 26, 2016 by robertwilkie

Almost fell over on this one.  The author basically takes a pair of IDE 2.5 to 3.5 adapters and puts a row of headers on the top to “mount” the board to. http://www.instructables.com/id/ESP8266-Solderless-Breadboard-Adapter/

Interests look at results of informal CNC software survey

Posted on August 25, 2016 by robertwilkie

Interesting look at what folks are using for CNC software.  Mach3 still rules overall.  But what is interesting is how LinuxCNC (and some versions of it commercialized) is gaining a bit over the past few years.  Also interesting is how … Continue reading →
