The Adafruit Dronies

I’m pleased to announce that I’m on the judging panel for the new Adafruit Drone Film Fest, the Adafruit Dronies 2016.

The Adafruit Dronies celebrates videos taken from drones. The contest is open to everyone in the United States to show and share their amazing drone videos. You’ll be judged on creative use of technology, storytelling, and cinematography.

Entries are limited to five minutes and winners receive trophies as well as gift certificates to the Adafruit store. The lineup of judges is amazing, and  we’re looking forward to seeing your entries!

GeekDad reviews The Annotated Build-It-Yourself Science Laboratory

DIY rain gauge

GeekDad has posted a very thoughtful review of the Annotated Build-It-Yourself Science Laboratory.

A workbench with breadboards, 3D printer, and sewing supplies is nothing compared to building a full science lab from basement junk.

They went hands-on and built the rain gauge shown above.

International RobotArt Competition

RobotArt logo with subtitle

We recently found out about the 2016 International RobotArt Competition for students to create art with paintbrush wielding robots and win prizes of up to $30,000 for their school.

For 2016, we focus on the technical side of creating art – the physical transition from raw color to applied color on a canvas. We challenge the participants to create artwork to showcase their robot’s abilities.

Rose-Hulman Institute of Technology Entry

The team registration deadline is March 1st, and the competition is open to high school and college student teams. Artwork must be uploaded by April 15. (This sounds like a perfect challenge for schools that have a WaterColorBot.)

Public participation in the first round of judging is encouraged, and then the works will be judged by professional art critics on originality, aesthetics, painting capability, and technical contribution (e.g. sharing source code.)

We love art robots, so we’ll look forward to seeing the results of this competition.

EggBots in Library Makerspaces

The New Sarepta Library in Alberta, Canada posted this video on twitter saying:

Our new EggBot is up and running! Come check it out!

We’re super happy to see libraries including our tools in their makerspaces.

A few years ago I used your bristlebot design for one of my kid’s classes as a project and it was such a success I’ve done it for each kid (I have 4).

We also made made “pontoon” versions of your bristlebots with 2 toothbrush ends underneath a cardboard oval so it looked like a beetle and gave the kids more decorating space.

Well, now I needed a new project and I came up with the easiest, cheapest Scribblebot I’ve come across, using mostly your bristlebot construction.

The big discovery is that a Dixie cup plus mini markers keeps the whole thing so lightweight. Then put your foam taped pager motor and battery combo on top. It was also way cuter with some antennae and googley eyes. Thank you again for your great bristlebot – it’s made me the most popular mom in each of my kids’ classes.

The bots shown were made by her daughter Kate who also demonstrates them in the video clips. Thank you Kate & Jessica!

Epic Cylon costume with Larson Scanner

I just received your Larson scanner for my Foam Cylon helmet today … I have since this video diffused the light inside the clear conduit pipe the LEDS are held inside of to make the LED effect a bit more smoother.

He has been posting updates of the costume on facebook.

Stippled Utah Teapot

Untitled

A Utah Teapot is an ideal design for a geeky ornament. For this one, I generated a vector stipple drawing from a photograph of the source object for this digital design icon. There are certainly many other ways to create a Utah Teapot ornament, including, of course, 3D printing.

In this case, I took our photo of our teapot, adjusted it to give it slightly higher contrast, and loaded it into StippleGen 2.

I removed any background stipples and plotted it on an ornament. The ornament is 2.6 inches in diameter and I used a 0.2 tip Copic Multiliner SP. I have posted the design on thingiverse.

RGB Interactive Table

Craig shared this project which evolved with the assistance of the Octolively project.

Thanks for the previous help you gave me when I was designing my own IR proximity boards. I thought you may want to have a look at the finished item.

I have attached a picture of the 25 100mmx100mm boards and a video of the table working. Each one had a SOIC PIC 18F26K22 on it, with 9 IR transmitters and receivers and 9 x WS2812b addressable LEDs on. They all kind of communicate with each other so that each board does the same IR reading of the same ‘pixel’ at the same time as the others. I simply have a pin on the board which outputs low whan it is working (taking a reading’, then after it is done, it changes to an input pin, it continually looks at this pin until it goes high, meaning all the other boards have also completed that particular reading and then it’s on to the next one.

I also have a calibration function so any thickness opaque covering can be put on the table top.

I have 2 buttons on it. One to change the colour (including the rainbow fade) and also a button to change the fade speed.

Thank you, Craig, for sharing your project! We’re glad you were able to get inspiration and helpful information from one of our projects.
