Super Awesome Sylvia has posted a video report from this year’s RoboGames. Highlights include a couple of combat matches, one of Sylvia’s LEGO competitions, WaterColorBot receiving a medal, and Sylvia completely geeking out after Grant Imahara interviewed her in the audience. (For extra fun, watch the raw footage of the interview from RoboGames.) Our STEAM shirt makes a cameo, too.
JK Brickworks made this amazing “pick and place” style Lego Mosaic Printer:
It is built entirely using LEGO parts. It first uses the EV3 colour sensor to scan the source image and save the data on the Mindstorms unit. It can then print multiple copies from the saved image data. The 1×1 plates used for ‘printing’ the mosaic are supplied using a gravity feed system and the printing head is simply a 1×1 round plate that can pick up and place the 1×1 plates.
More information about this project can be found at JK Brickworks.
They posted a picture of the finished painting, which looks awesome.
The article Can Analog Circuits Inspire Budding Engineers? over at Planet Analog discusses preparing students for dealing with real world circuitry by getting them started with analog circuits.
By building, probing, and observing the signals and their changes in these circuits without any code requirements, students can get a real feel for otherwise abstract concepts such as voltage, current, and more.
The author uses examples of projects and kits including our very own Three Fives Kit.
3D printing is a common maker topic, and MakerCon brought a few different twists to it. Above is Gael demonstrating InMoov, an open source 3D printed humanoid robot. There was also an incredibly inspiring talk about applications for medical 3D printing by Dr. Glenn Green.
3D printing can be whimsical as well, as demonstrated by this “25 mm” drill bit by Gigabot.
The folks from Strawbees had built a quadcopter rotor cage with a clever servo actuator for flapping sculptural wings.
I enjoyed seeing this attractive laser cut living hinge at the BotFactory demo.
Rogue Rovers are electric semi-autonomous ATVs designed for agricultural use to reduce farm injuries and pollution.
More pictures from the event are in my flickr album.
To design it I started from the Evil Mad Scientist’s CNC Workstation Cart redrawing to adapted it to our necessity as an horizontal PC, cables space inside, and last but not least without any screw or glue.
She posts about her design process, including prototyping using a laser cutter to make a scale model. It looks great—we especially like the cutout drawer handle design.
Look what just arrived in the mail– Blinky AVR Earrings!
Four blue LEDs blink in sequence, powered by a CR1220 battery. The board is traditional OSHPark purple, with an ISP header for convenient reprogramming. They’re lighter than they look and quite comfortable.
Thank you, Rick! I know what I’ll be wearing to Maker Faire!
Congratulations to our friend RobotGrrl, who took home a gold medal in the Best of Show category.
