Build a card reader and display

Posted on April 4, 2017 by robertwilkie

This is neat, if you get the parts from china you can build this for around $15.  Basically the system will scan you card, then display the number value out on the screen.  This could be useful in debugging problems … Continue reading →

Make your own LED flood lights

Posted on April 4, 2017 by robertwilkie

Nice build.  The cost is $15 in parts (wood and wire free).  Time to build could be a bit intense.  Since the same thing would run around $40 its not a bad price.  Plus you could customize this for your … Continue reading →

Make a simple water purifier with 2 soday bottles and a copper wire

Posted on April 4, 2017 by robertwilkie

Make a simple wifi jammer for $7

Nice build for a magnetic stirrer

Posted on April 3, 2017 by robertwilkie

Make your own pocket hole jig

Posted on April 3, 2017 by robertwilkie

I like this build, but…bit time consuming to make.  However considering how much the kreg jibs run for these days, maybe worth trying out. http://makezine.com/2017/03/27/diy-pocket-hole-jig/

Posted on April 3, 2017 by robertwilkie

Pretty nice build, Only downside is if you buy NeoPixels from say Adafruit, its going to run you around $20 just for the LEDS (not including power supply, arduino…etc). https://www.instructables.com/id/Arduino-Colorful-Clock-Using-Neopixel-Strip/

Make a simple portable panel saw

I love these things at home depot.  But as the author points out, they are very expensive and not exactly something that you can move around.  This is a nice build to make one much cheaper  and portable (oh and … Continue reading →
