Popup Notification Dinosaur

There’s a lot going on our virtual spaces, and anyone with a smart phone can attest to this fact. There are pop-up notifications for everything you can imagine, and sometimes it’s possible for the one really important notification to get lost in a sea of minutiae. To really make sure you don’t miss that one important notification, you can offload that task to your own personal dinosaur.

The 3D-printed dinosaur has a rack-and-pinion gear set that allows it to extend upwards when commanded. It also has a set of LEDs for eyes that turn on when it pops up. The two servos and LEDs are controlled by a small Arduino in the base of the dinosaur. This Arduino can be programmed to activate the dinosaur whenver you like, for an email from a specific person, a reply to a comment on Reddit, or an incoming phone call to name a few examples. Be sure to check out the video below the break.

With this dinosaur on your desk, it’s not likely you’ll miss its activation. If you’d like something that has the same function but with less movement and more lights, there’s also a notification 3D cube made out of LEDs that’s sure to catch your eye as well.

TerraDome Gives Plants And Dinosaurs A New Home

Housing exotic plants or animals offer a great opportunity to get into the world of electronic automation. When temperature, light, and humidity ranges are crucial, sensors are your best friend. And if woodworking and other types of crafts are your thing on top, why not build it all from scratch. [MagicManu] did so with his Jurassic Park themed octagonal dome built from MDF and transparent polystyrene.

With the intention to house some exotic plants of his own, [MagicManu] equipped the dome with an Arduino powered control system that regulates the temperature and light, and displays the current sensor states on a LCD, including the humidity. For reasons of simplicity regarding wiring and isolation, the humidity itself is not automated for the time being. A fan salvaged from an old PC power supply provides proper ventilation, and in case the temperature inside the dome ever gets too high, a servo controlled set of doors that match the Jurassic Park theme, will automatically open up.

[MagicManu] documented the whole build process in a video, which you can watch after the break — in French only though. We’ve seen a similar DIY indoor gardening project earlier this year, and considering its simple yet practical application to learn about sensors, plus a growing interest in indoor gardening itself (pun fully intended), this certainly won’t be the last one.

Mechanical Build Lets You Jump Cacti in Real Life

Simple to learn, hard to master, a lifetime to kick the habit. This applies to a lot of computer games, but the T-rex Runner game for Chrome and its various online versions are particularly insidious. So much so that the game drove one couple to build a real-world version of the digital game.

For those not familiar with the game, it’s a simple side-scroller where the goal is to jump and duck a running dinosaur over and under obstacles — think Flappy Birds, but faster paced. When deciding on a weekend hackathon project, [Uri] thought a real-life version of the game would be a natural fit, since he was already a fan of the digital version. With his girlfriend [Ariella] on the team, [Uri] was able to come up with a minimally playable version of the game, with a stepper motor providing the dino jumps and a simple straight conveyor moving the obstacles. People enjoyed it enough that version 2.0 was planned for the Chrome Developer Summit. This version was much more playable, with an oval track for the obstacles and better scorekeeping. [Uri] and [Ariella] had to expand their skills to complete the build — PCB design, E-Paper displays, laser cutting, and even metal casting were all required. The video below shows the final version — but where are the pterosaurs to duck?

Real-world jumping dinos aren’t the first physical manifestation of a digital game. As in the cyber world, Pong was first — either as an arcade version or a supersized outdoor game.

Upgraded Roboceratops Still Not Extinct

We first heard about [Robert Stephenson]’s robotic baby dinosaur a few years ago, and recently he made some upgrades.

Roboceratops V2 uses 10 servos in the jaw, neck, tail, and front and back legs with 16 degrees of freedom—the two front legs each got an additional degree of freedom in the upgrade. [Robert] is currently in the process of swapping out the Hitec HS645 MGs for higher-torque New Power XLDs.

The older version had aluminum legs covered with upholstery foam, but [Robert] has refined the design. The head, body, and legs are made from laser-cut MDF sanded to give a more natural, bone-like rounding. Finally, to better make use of the new servos [Robert] rewrote the gait engine, giving Robosaurus a more natural motion as it adjusts its center of gravity with each step.

So, for the next version are we all on board for simulated skin?

Raspberry Pi Brings New Life to Some Old Dinosaurs

Reprogramming the behaviors of a person-sized animatronic dinosaur would have to be among the coolest opportunities to be presented with… This is exactly what [Dr. Lucy Rogers] and a group of fellow techies were tasked to accomplish for the Blackgang Chine park located on the Isle of Wight in the UK.

dino1Before the group arrived, the native dinos didn’t do much else than run a preprogrammed routine when triggered by someone’s presence… which needless to say, lacks the appropriate prehistoric dynamism. Seeing that their dated wag, wiggle, and roar response could use a fresh breath of flair, the park’s technical projects coordinator [Mark Butler] began adapting one of the dinosaur’s control boxes to work with a Raspberry Pi. This is when [Lucy] and her group were called upon for a two-day long excursion of play and development. With help and guidance from Raspberry Pi expert, [Neil Ford], the group learned how to use a ‘drag and build’ programing environment called node-RED in order to choreograph new movement sequences for two of the smaller dinosaurs provided for use. The visual nature of node-RED helped those of the Blackgang staff with little programming experience understand the code at work, which aided in their training. Now they can reprogram the dinosaurs with new actions on the fly if needed.

The Pi in the end turned out to be a cost-effective solution which will give the robot dinosaurs a longer, more fulfilling lifespan to roar and frolic on their island home. Check out this video by [Debbie Davies] to see more…

Thanks Ed, for spotting this one!

Dinosaur hoodie to remind you Halloween approaches!!

[Tom’s] dinosaur hoodie would make a bang up Halloween costume. It’s a glowing version of the bony plates you’d find on a Stegosaurus. Not only does it look great at night, you should be able to put one together or yourself in an afternoon.

He used a laser cutter to make the translucent fins, but it would not be hard to cut them all out by hand. Each piece is two sides of the plate connected by a narrow rectangle which leaves room inside for an RGB module. These are chained together and controlled by an Arduino (most likely using SPI or I2C, we’re not sure which), then sewn on the back of a hoodie.

Update: [Matt] made a derivative of this design. The plates are pointy like a stegosaurus.

Send in those Halloween projects

Which reminds us… Halloween quickly approaches and we haven’t seen the usual onslaught of awesome. We love this time of year because of the ingenuity that comes out to play in the costumes, yard decor, and scare tactics being prepared for the big night. Please send a link to your project and we’ll start pumping out the holiday features.

To get you thinking, here’s a set of folding wings used in a costume, and a possessed powerwheels to chase down the little ones. Don’t sit on your hands, we want to hear about every project!

How to be a dinosaur for Christmas

Well, this metal suit might not make you a dinosaur, but it would be perfectly possible for you to play one on your computer. Retailing on eBay for a mere $2,397.99 OBO (plus Freight for a 350 pound box), this device was made and used for the motion capture of Ugobe’s Pleo Robot. With the right external components (no word on what those are), it would be perfectly possible to get this suit up an going back on Motion Capture as all the onboard electronics are included. This setup would be perfect for anyone planning an animated dinosaur movie that needs some reference movements, or for any mad scientist engineer who needs a control rig for a 40 story robotic dino of death. The possibilities are endless!
