Welding a Welder Holder to a Welding Cart

weldCart2

I have this great little welding cart I got from a picker. The size was almost — but not quite — perfect to hold my little MIG welder underneath. I got 10′ of 1/2″ 16 gauge steel square tubing for $2.06 at Industrial Metal Supply’s remainders bin and cut two lengths down to size to fit the footprint of the welder.  I welded them to the cart and now it’s all neatly contained.

Arduino GRANDE Tutorial

I love Arduino! But the boards are so tiny that they can be difficult to hug. And not so easy to see, either, if you’re a student sitting at the back of a classroom. So why not solve both problems by building a really huge, fully-functioning Arduino that’s six times larger than real life?

By popular demand, I finally put together a tutorial for building your own not-so-micro microcontroller:

Building a 3D Printer Turntable

 

I built this turntable for my Ultimaker 2 3D printer. Why? Because each time I changed the material on it I needed to go from using the interface on the front to dealing with the spool and filament on the back of the machine three times. Minor annoyance, I know, but I had had enough!

You can’t wing this too much or things won’t line up, so I did some careful measurements and aligned things well enough that when I blind screwed in the bottom it worked. There are strategies for doing this with large holes predrilled at a 45 degree offset from square so you can screw them in and see what you’re actually doing, but where’s the sport in that?

Now I’m already regretting not making the top piece a circle or gear pattern so I can motorize this for stylish stop motion photography of timelapse printing, but I think I can add that feature later.
