I forsee folks getting free parking in the future

The author figured out how to sniff some of the garage gates and get them to trip using an 433 MHz OOK module and an arduino.  I see a future here where folks use this to bypass parking garage gates.

This lounger was made out of 2×4 like materials

This is pretty amazing looking bench.  What really impressed me is the whole thing was originally a bunch of 2×4 and 2xX planks.  The author then used a grinder bit called the “Turboplane” (at $130) to carve out the chair.  If it wasn’t for the cost of the tool, I would be tempted to do this.

A simple and cheap battery holder

Take a bunch of plastic bottle tops and make your own simple battery holder.  Not a bad idea especially if you are in a pinch.

This plotter is the perfect build for kids

This plotter could not be easier to build.  4 rulers, 2 steppers, and a servo are all you need…oh and ways to bolt the rulers together.  Oh and an arduino and stepper controllers too.

Another Magnetic Stirrer, this one with a harddrive magnet

Another nice (build for a magnetic stirrer.  Only two issues, one I don’t come across alot of barrel receivers in scrap/recycling I do.  Second is the need for a 12 volt wall wart.  I have 5’s, 9’s, but 12’s are pretty rare for me.

Make an beer pack with your CNC

Nice build.  If you have a tabletop sized CNC that is.

HAHAHAHA this is a pretty clever build for cutting bars the same size

The author uses an arduino and a home made encoder to measure the cuts.

Github Dorks, way to scan your code in git for security issues

Mostly for username/password and other credentials.  Not a bad idea since its amazing how many folks hardcode these things into code.

Use and App to make graffiti

https://i.kinja-img.com/gawker-media/image/upload/s–uDoNH6Mv–/c_scale,fl_progressive,q_80,w_800/utowsidnmcflj77z8odd.gifOK so the app helps you draw like a CNC a picture on a wall with a can of spraypaint.  There goes the graffiti artist industry.

Did you want to use a Vinyl Cutter with Linux?

If so here is a a nice write up on how to use Inkscape with Ubuntu and a Silhoeutte cutter.  Been toying with the idea of getting a cutter for a few years myself.
