CNC Circuit Playground Holder

I decided I needed a Circuit Playground and Circuit Playground Express render farm. Here’s the stand I made on the CNC machine.

I designed it in Fusion 360 and then milled it with the Othermill Pro.cpFarm_IMG_2511 First, I ran a pocket clearing pass.

Next, I ran a pencil pass to clear out the scooped out slots for the curvature of the boards.

These rough passes left behind a bit of material, as you can see here.

The final cleanup was a parallel pass with a fairly tight stepover, I ran it at 90 degrees from the stock, so it followed the grooves and had longer runs.

Here it is with a Circuit Playground Express nestled in it lovingly.

Here you’ll see some purple prototype boards, and the new red Circuit Playground Classic Digi-Key will be selling as part of the “buy one , give one” donation program for Girls Who Code

Here’s the full set, ready for various tutorials I’m working on with MakeCode, Arduino, and Circuit Python!

Estate Sale pan and knife

Hit a semi-disappointing sale this morning. Not too much of interest, or as pickers say, nothing had any age on it.

The two finds I did get: a great little Griswold no. 3 cast iron pan for $5. Nicely seasoned, probably perfect for a grilled cheese sandwich I’ll be making for lunch…

The other thing I picked up is this kooky Keen Kutter pocket knife. It’s a bone handled Barlow model, made from 1940-1960. Blade marked “K288 1/2”.

I call it kooky due to the tip. Looks like the previous owner snapped it off and then did a nice job cleaning it up into a concave dip. I probably paid too much at $10, but I like its apparent history.

I can tell from the other knives at the estate that the previous owner really had a problem with using knives as screwdrivers/pry bars. At least this one has a nifty attempt at saving it.

Coffee & Tool & Coffee Tool of the Day

Today I’m featuring an electrician’s Leatherman, the E4 Squirt, and a Modern Times (beer brewer/coffee roaster from San Diego) Black House coffee brewed in a Bialetti moka pot my mom gave me. (I think it was from my Zia Wanda’s kitchen in Cassino, Italy.)

I really like the E4 because it’s got a good set of wire strippers/cutters on it, and the Philips screwdriver is a pretty nice one. I keep it in my jeans coin pocket.

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.
