Ever wish you could augment your sense of sight?

[Nick Bild]’s latest hack helps you find objects (or people) by locating their position and tracking them with a laser. The device, dubbed Artemis, latches onto your eyeglasses and can be configured to locate a specific object.

Images collected from the device are streamed to an NVIDIA Jetson AGX Xavier board, which uses a SSD300 (Single Shot MultiBox Detection) model to locate objects. The model was pre-trained with the COCO dataset to recognize and localize 80 different object types given input from images thresholded in OpenCV. Once the desired object is identified and located, a laser diode activates.

Probably due to the current thresholds, the demo runs mostly work on objects placed further apart against a neutral background. It’s an interesting look at applications combining computer vision with physical devices to augment experiences, rather than simply processing and analyzing data.

The device uses two servos for controlling the laser: one for X-axis control and the other for Y-axis control. The controls are executed from an Adafruit Itsy Bitsy M4 Express microcontroller.

Perhaps with a bit more training, we might not have so much trouble with “Where’s Waldo” puzzles anymore.

Check out some of our other sunglasses hacks, from home automation to using LCDs to lessening the glare from headlights.

[Will] wanted to build some animatronic eyes that didn’t require high-precision 3D printing. He wound up with a forgiving design that uses an Arduino and six servo motors. You can see the video of the eyes moving around in the video below.

The bill of materials is pretty simple and features an Arduino, a driver board, and a joystick. The 3D printing parts are easy to print with no supports, and will work with PLA. Other than opening up holes there wasn’t much post-processing required, though he did sand the actual eyeballs which sounds painful.

The result is a nice tight package to hold six motors, and the response time of the eye motion is very impressive. This would be great as part of a prop or even a robot in place of the conventional googly eyes.

While the joystick is nice, we’d like to see an ultrasonic sensor connected so the eyes track you as you walk across the room. Maybe they could be mounted behind an old portrait for next Halloween. Then again, perhaps a skull would be even better. If you want a refresher about servos, start with a laser turret tutorial.

LightByte: Animated Shutters

arduino hacks, mit media lab, servos Commenti disabilitati su LightByte: Animated Shutters 

lighrbright

Here’s another interesting project to come out of the MIT Media Lab — it’s called LightByte, and it’s all about interacting with sunlight and shadows in a new, rather unorthodox way.

We suppose its technical name could be a massive interactive sun pixel facade, but that’s a bit too much of a mouthful. What you really want to know is how it works, and the answer is, a lot of servos. We weren’t able to find an exact number but the hardware behind LightByte includes well over 100 servos, and a matrix of Arduinos to control them. While that is quite impressive by itself, it gets better — it’s actually completely interactive; recognizing gestures, responding to text messages and emails, and you can even draw pictures with the included “wand”.

We love anything mechanical like this — it’s just something about mechanical shutters that make them so awesome. Of course, reverse-engineered flip dot displays are pretty cool too! Or massive home-made flip-dot displays like this one…

[Thanks Alexander!]

Hexapod legs in build and hooked up to Arduino Mega should be fun to tinker with

arduino mega, hexapod, PC, servos Commenti disabilitati su Hexapod legs in build and hooked up to Arduino Mega should be fun to tinker with 

Leg one took an hour and a half, the next 3 took less than an hour to build. They are 0.75 mm aluminum sheet



Have as s-ramp working on the axes make the movement quite smooth. 
Using cheap hextronik HTX900's on the legs and HK939 MG's son the shoulders, have more servos on the way  as I suspect I will trash a few.  



Design inspired by Hexy

Will use an Xbee or HK 900MHx telemetery transceiver for base link. I'm thinking cams and linear interpolation  like a Trio motion system like the one I worked on in the wheel motion system shown below.


This one has some good explanations and design insight

An interactive Twitter clock with a vintage twist

Tweety

Johannes Hoffmann is an interaction and graphic designer sharing with us his  hand-made Tweety Clock. It’s a vintage but interactive Twitter clock , built with Arduino and Ethernet Shield, and featured with the original ‘cuckooo’ sound and a little printer for the output.

Arduino is checking if there are new tweets from a specific Twitter-Account. If so, the “bird servo” starts to rotate and the bird-door opens. Then the two “sound servos” brings the Cuckoo Clock flutes to sing and the bird nod with his head. Simultaneously, the thermo printer prints all new tweets.

Moti on Kickstarter: spin the dials and the motors follow!

kickstarter, motor, Robot, servo motor, servos Commenti disabilitati su Moti on Kickstarter: spin the dials and the motors follow! 

moti on kickstarted

Moti is a smart motor you can control from an app . It allows to use your fingers directly on the screen to move the motor, adjust speed with sliders and even program motions with simple building blocks. You can attach it to any kind of objects and bring them to life with intuitive and easily understandable steps.

At the same time Moti is advanced enough to satisfy makers and developers who are looking to build complex robots. Each one is programmable with Arduino, has bunch of built-in sensors, daisy-chains, and even has a web-API so you can develop sites and games for your robot.

Nick wrote us:

Our aim with Moti is to make robotics accessible to everyone by providing a
tool that’s as intuitive to use as a hammer. Simply attach Moti smart motors to anything and then use the graphical app to bring your creation to life…spin the dials and the motors follow. Presto, instant robot!

Moti was born out of our frustrations in building robots.  We’ve just done a lot of the grunt work so you don’t have to.

At present, a lot of low level work is required to get a robot moving, and that prevents most people from exploring beyond the basics, if at all. Moti simplifies robotics so more people can apply it to interests such as amateur filmmaking, animatronics, window displays, art projects, 3D printed robots, DIY toys, RC vehicles, home automation and much more.

In the 80′s computing shifted from labs and industry into everyday life. We think robotics is ready for a similar shift, and Moti is here to help that happen.

They are on Kickstarter now! See how it works:

A cake maker with a passion for engineering and Daft Punk

DaftPunkCake

Shantal Der Boghosian is the owner and cake decorator of Shakar Bakery, but also an engineer and a chemist based in Los Angeles California. She recently wrote us to share her 5ft (152cm) tall tribute cake for Daft Punk, the French electronic music duo, and created together with her sister and Garen (coder).

DaftPunk1 DaftPunk2 DaftPunk3

The cool thing about this project is that the bodies of the band are made of cake and the heads move at the rhythm of the track “Get Lucky”, controlled by Arduino Mega.

This project took 2 months to design, over 100 hours to build the structure and another 100 hours spent on the electronics, programming, and mechanics . We had a lot of bumps in the road and we worked through every single one. This was the first time I ever built a cake structure, the first time I sculpted with rice krispies, and the first time I built a cake on such a massive scale! This was Garen’s first time coding an Arduino servo, and creating head motions that defied weight restraints! I have to admit that we did a last minute surgery to the silver helmet to make the “no” motion more fluid.

Enjoy the video below and take a look at her detailed blogpost with all the phases of the complex yummy construction!

animatronic eyes

Thanks to Lance who created a project on Instructables,  you’ll be able to create remote-controlled eyes using Arduino Uno, two servos, some plexiglass and a couple of doll’s eyes.

If you like animatronics,  watch the video below: the result is pretty scary!
