Make a mini tesla coil

Posted on November 30, 2017 by robertwilkie

Nice build and pretty small too.  Most of the parts can be under $10 total.  (well caps may not be, and I am assuming you already have wire). https://makezine.com/2017/11/26/twim-holiday-gift-guide-diy-tesla-coil-crossbow/

Nice speaker build

Posted on November 29, 2017 by robertwilkie

I like the build itself, just…bit costly in parts.  I have been thinking about taking an Anker based bluetooth portable speaker and adapting it to something like this. http://www.instructables.com/id/Remote-Control-Bluetooth-Light-Switch/

Interesting build for an automated light switch (bluetooth)

Posted on November 28, 2017 by robertwilkie

I like the build.  But…not so sure I would use Bluetooth, maybe use an ESP and get wifi instead.  I like Wemo switches but they are sometimes hard to fit in older light boxes, and this could be cheaper too.  … Continue reading →

Nice looking rain barrel diverter.  I like the hose adapter so you can move the barrel farther away.  My 2 cents, I would make sure the bottom can be un-screwed for cleanout too. http://www.instructables.com/id/Rain-Barrel-Diverter/

Another interest solar power water distiller

Posted on November 20, 2017 by robertwilkie

I like this build a bit better than others I have seen.  This one you can “stand up” easily.  Downside…still hard to get end result water out. https://www.instructables.com/id/Solar-Powered-Water-DistellerFilter/

Another nice survival stove

Posted on November 18, 2017 by robertwilkie

bascially the author put a bunch of rolled up cardboard in a can and covered it all in wax to make a giant candle.  Not a bad idea.  Not so sure I would use it in my house thought. https://www.instructables.com/id/TIN-CAN-Air-Heaters-SurvivalSHTF-Air-HeaterStove-S/
