I’m building an Overwatch prop gun — Lucio’s blaster — from scratch. Here are my videos for the first two parts of four(?) that I’m planning.
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.
I’m thrilled to announce that after a decade of moonlighting in the maker movement, I’m now officially a full-time maker and content creator! Starting this week, I’ll be working from my Southern California workshop, designing and building projects and videos for Adafruit Industries.
Adafruit is an open source hardware and electronics company founded by the awe-inspiring engineer Limor “Lady Ada” Fried, and co-run by the highest energy element on the the periodic table, Phil Torrone. I’ve know these wonderful people since the beginning of the maker movement, working together on Make: magazine, Maker Faires, and the Emmy-nominated Make: Television show on American Public Television. I’m proud to be joining them and the rest of the incredible team in our shared goal to encourage and enable anybody to build anything.
There are so many projects I’m excited to start building and sharing in videos and online tutorials. I’ll be making things to appeal to people with wide ranging passions, including cosplayers, home brewers, gamers, magicians, rock climbers, hot rodders, modernist chefs, lock pickers, kids, musicians, mixologists, Burners, escape room designers, aerialists, cyclists, teachers, animators, and coffee fiends, to name a few.
If you’ve got an idea for something you’d like to see me make, please drop me a note in the comments or on my Twitter @johnedgarpark.
You’ll be able to watch my Adafruit videos here, my Learning System tutorials here, my posts on the Adafruit blog. I look forward to meeting you in the Adafruit online hangouts. I’ll also be doing collaborations, speaking, teaching, and other maker activities, please follow my blog for updates — you can subscribe in the sidebar over there on the right.
Hey look, the new book is out! That’s my flower care robot, Chauncey, there on the cover. (He waters that flower whenever the soil runs dry.)
I’m very excited and proud to have contributed to this lovely new book from Maker Media chocked full of projects you can build with a 3D printer, some electronics and mechanical parts, and a bit of gumption. The central notion behind 3D Printing Projects: Toys, Tools, and Contraptions to Print and Build Yourself is “You’ve got a 3D printer, and you’ve downloaded and printed a few Yoda heads and vases — now what?”
The projects all go beyond static prints, and into functional builds that show the true utility of desktop prototyping and additive building when combined with other techniques, including print finishing/painting, friction welding, embedded electronics, physical computing, and mechanism design. Downloadable model files are available on the book’s companion site, and we’ve got a GitHub repository set up for any code downloads, such as the Arduino sketch that powers my flower bot.
I’d like to also give an enormous public, internet hug and thank you to my creative collaborator, Barry McWilliams, who inspired me with his Wrylon Robotical Illustrated Catalog of Botanical Delivery ‘Bots, and who designed my darling little robot, Chauncey.
If you’re interested in learning how to make your own Chauncey, or animatronic eyes, or a ballpoint pen raygun, an inverted RC trike, and more, from a very talented group of makers, including John Baichtal, James Floyd Kelly, and Brook Drumm, please check it out on Amazon, at O’Reilly, in your local Barnes & Noble, or other local bookstore. I promise it will give invigorating new purpose to your 3D printer!
To place the sensor out under a bush or fence for Halloween, I wanted to run a long length of CAT5 cable from it to the Arduino Uno running things. I mounted the rangefinder (a Maxbotix from Adafruit) to a RJ45 breakout board from Sparkfun, angling it up so the sensor can be placed low to the ground.
In the original application, I was able to hide this under a giant furry Neverbeast head (from Tinkerbell and the Legend of the Neverbeast) coming out of the floor in the lobby of Disneytoon Studios. But now I needed to place on outdoors, so I decided to model and 3D print this little enclosure.
Finally, I mounted another RJ45 breakout in my Arduino/WaveShield case and ran the voltage, signal, and ground wires to the Arduino.
Now, I’ll be able to set this up to scare trick or treaters this Halloween as they get near the house.
My son has begun playing ukulele. We needed a way to store it, so I found this lovely winged ukulele hanger model on Thingiverse.
I have a bad habit of building prototypes right in front of the keyboard I need to access for coding said prototypes.
I’m giving a talk about desktop 3D printing at Disney for an internal symposium on creativity. While there has been a lot of industrial 3D printing at Disney for many years, the immediacy and accessibility of inexpensive desktop 3D printers changes how we interact with out digital designs. Creative iteration is the key — I find it incredibly empowering to print a work-in-progress character or prop model any time I want to show it to others for feedback.
I’ll be giving a brief history of desktop 3D printing, starting with the RepRap project, show examples of how we’ve used 3D printing at Disneytoon Studios, talk about some future developments in desktop 3D printing, and discuss what the maker community is up to in this space.
In preparation, I’m printing a few examples of popular objects on Thingiverse. Here’s the gear cube:
I bought a couple of sheets of this 3D printer build surface material from BuildTak when I was at Bay Area Maker Faire 2014. It works much better than the blue painters tape we were using on our 1st gen. Ultimaker at work, printing PLA plastic. The trick is in finding a material to which the printed plastic will adhere well enough for stable printing, but not so well that it is too difficult to remove the object when finished.
Note: As seen in the bottom-right photo, I wasn’t very careful laying down the sheet, and managed to trap a few air bubbles. Oops. Hopefully that won’t create any terrible problems with critical prints.
Get some here at BuildTak. This sheet was around $10 and should last for many, many prints. How many? I’ll let you know.
