Dallas Makerspace Show and Tell - August 2016

The two of you are identifiable at the Fuel City spot … But only if you look quickly.

As soon as we got back into the car I said something about how there would be a few frames of us derping at the camera.

Thanks. This old woman has learned her new word for the day.

On the camera, I would be inclined to tether it to the vehicle under the theory that a few bangs agains the vehicle is probably less damage than tumbling down he road at speed if something went wrong.

Some of y’all may have seen me working a giant new printer. I am a pretty much done with all of the hardware, just tweaking and refinement at this point.

The printer almost (just small stuff left) assembled and working.

I made this coin for Gishwhes (the Greatest International Scavenger Hunt the World Has Ever Seen) - I was super excited that there was a metalsmithing item this year! Even better that it finally got me to try out etching. So much potential here.

I also went to New Jersey last week and took an Enameling (torch and kiln-fired) and Die-forming workshop. I didn’t leave with any finished pieces, but I started to finish them at the space.

Earrings, textured using a center punch and over-fired white:

Necklace - blue/purple front/over-fired white back - the over-fired white isn’t quite so green on the back…my phone didn’t do a very good job with the color.

Kobo Mini e-ink reader + GPS module from Adafruit + 3D printed spacer/holder + repurposed S/W from the Ultralight community = $55 daylight-readable large screen GPS.

Finally (mostly) finished my western style chinks (like chaps but a little shorter). Trailriding planned for Sunday to try them out.

my latest pen design. Since skulls are so popular I thought I would experiment with this.
this is a 3d raised body pen with raised skulls on a cocobolo blank.
They are rotary turned on my home CNC since we don’t have a rotary fixture for any of the DMS CNCs. So it’s just presented here for design posibilities.
cheers!

I’ve been working on a 3d printed P-47 Thunderbolt, printed from PETG. It’s all single layer walls, no infill and hollow inside aside from some structural ribs. The fuselage is done, I’m now working on the wing. When complete, it will have a 48" wingspan. It has ailerons, rudder, elevator, and retracts.

XCSoar is pretty purpose-built for a few different flying communities… what are you going to do with it?

I plan to use it for horseback riding: a large daylight-readable map is useful. Since XCSoar is FOSS, I might tweak it to be a little more non-flyer friendly, mostly by suppressing the MANY options for racing, waypoints, wind, terrain collision, et al which don’t really apply to ground travelers.

If you get into some XCSoar hacking, I would be very interested to talk about the experience.

With much help from @wandrson, I made an indexing plate for my Taig micro lathe, an indexing pin, and a block that holds the indexing pin. This involved the Bridgeport (and the dividing head - which was a great learning experience), the metal band saw, the lathe, some taps and of course the parts washer (which was also new for me).

Here the Bridgeport is drilling the outer circle of indexing holes in 1/8" 5052 aluminum (which is coated with blue DyeKem). And I have to say … LOVE, LOVE, LOVE that power drawbar! No more ladder for me! :heart_eyes_cat:

When I assembled it, much to my dismay (but sadly, not to my surprise) my tolerancing was a bit off. The index pin that mates with the holes in the disk didn’t align quite right. However, after wallowing out the hole in the mounting block with a bit 0.005" larger - voilà! It works.

Now I just need a filing attachment to go with it.

I took the 3D Needle-felting class last night and may have found a fun new obsession.

With some artwork from the designers at the office and new laser cutter training at hand we took to learning in detail how to get use out of the thunder laser. We made a sign for the office, some dashed line cardboard signs that my wife painted, and a slotted structure body for a Mike wazowski (monster’s inc) halloween costume.

So using the tutorial I posted here: How to Use the Gocupi in the Hallway and some help of @Ed_Krohne figuring out how to use Curves instead of Levels in GIMP to change the light and dark contrast. I was able to draw this incredibly detailed @JohnK head (I’m sure he’ll love finding this since I didn’t ask his permission).

Also if you go to my M:\MitchC\GocupiConverter\ there’s a GIMP Portable so you can run GIMP without needing admin rights on the space computers.

A huge thanks to @Perpetual for the webserver and interface, it has made the Gocupi 100x more accessible for anyone to use it.

I very much enjoy the added visual effect of extra long stray hairs coming out of Johns beard.

Hey, any picture on the Wiki member page is fair game IMO. Impressionist John K, Monet would be proud.

Since I joined, there has been a steady decline in the number of random @JohnK heads around the 'space. Thanks for helping restore it to it’s original ‘surprise @JohnK head around every corner’ glory
