FEETECH High-Torque Servo FS5115M

via Pololu Blog

We added the FEETECH High-Torque Servo FS5115M to our expanding RC servo selection. This standard-size analog servo has a stall torque of 215 oz-in (15.5 kg-cm) at 6 V, more than twice the torque of our standard-size servos with plastic gears thanks to its powerful motor and all-metal gear train. This higher torque requires more power: this servo can draw bursts of current in excess of 3 A at 6 V, about three times higher than a typical standard-size servo. The output shaft is supported by two ball bearings for reduced friction.

Comparison to the Power HD 1501MG high-torque servo

This servo is a lower-cost alternative to the 1501MG from Power HD, which has nearly identical dimensions and similar performance. The two servos should be generally interchangeable for most applications. The picture below shows both the FS5115M and the 1501MG side by side:

Expect more new FEETECH servos in the coming weeks!

After browsing the show floor, don’t forget to visit our booth inside Pavilion 22, Stand G26, Workspace 3.0!

There, attendees will have a chance to play games, participate in giveaways, and learn more about our latest products. Moreover, be sure to get a glimpse of the great “Bridge” project from the Accademia di Architettura of Mendrisio, Switzerland–a fantastic demonstration of how Arduino can be used in architecture.

We look forward to seeing! Until then, more information can be found here!

Pioneers Winners: Make Us Laugh Challenge

via Raspberry Pi

After months of planning and making, we’ve come to the end of the first cycle of our new digital making programme for teenagers: it’s time to announce the Pioneers winners!

We laid down the epic challenge of making us laugh. And boy, did the teams deliver. I can honestly say that my face hurt from all the laughing on judging day.

The judges

The aim was to find a group of judges with a varied mix of interests and skills. We were beyond chuffed to snag this awesome group:

Dr Lucy Rogers

Dr Lucy Rogers transforms simple tech into cool gadgets, science into plain English, and problems into opportunities. She’s a fellow of the Institution of Mechanical Engineers and author of the books ‘It’s ONLY Rocket Science‘ and the soon-to-be-published ‘Wiring the IoT‘. She’s also a Raspberry Jam organiser, a judge on BBC’s Robot Wars, and the person responsible for introducing Raspberry Pi-controlled animatronic dinosaurs to the Blackgang Chine Land of Imagination on the Isle of Wight.

Owen Daughtery

Owen Daughtery is a graduate of Raspberry Pi’s Creative Technologists programme and an enthusiastic maker. You’ll no doubt recognise him from our original Pioneers videos and his inability to say a certain phrase. When he’s not making videos for us, or for his YouTube channel, Owen is also a skilled magician.

Bec Hill

Comedian Bec Hill has a talent for incorporating arts and crafts into her stand-up routines, creating a unique and unforgettable comedy style that she calls ‘paper-puppetry’. She’s also creator of Pun Run, one half of entertainment duo Bec & Tom, and has voiced several characters for the newly released Mass Effect: Andromeda.

Maria Quevedo

Maria Quevedo gifMaria Quevedo is the director of Code Club UK. She’s amazing at yoga, cooks a mean Spanish tortilla, and originally hails from Argentina. She was also raised in a stationery shop, which is pretty much my dream. According to members of the Code Club team, Maria is delightfully calm under pressure…though she did fail to keep her cool when faced with judging the Pioneers winners.

The Pioneers winners

Winners of the first Pioneers challenge are…

After months of planning and making, the first round of Pioneers is over! We laid down the epic challenge of making us laugh. And boy, did the teams deliver. We can honestly say that my face hurt from all the laughing on judging day. Congratulations to everyone who took part.

Congratulations to the theme-winning team The Technological Tricksters and their project, Singing Potato. As Bec explained in the video, this project made us laugh…a lot. And through our tears of laughter, we were pleased to see the use of several different skills, along with a killer Gollum impression.

Alongside the overall theme winner, we also awarded prizes for the following five categories:

  • Inspiring Journey: the winners of this award experimented with a range of technologies, learned new skills and produced a final project that worked perfectly. Congratulations to Heritage Hackers and their Water Pistol Trap for winning this award.
  • Best Explanation: the team that hit the perfect balance of detail about what they made and how they made it were Black Thunder. We loved the explanation you gave for building your Living Joke Robot. Well done!
  • Technically Brilliant: the team that used the most impressive combination of technologies were the Shady Hackers with their Scare Chair Rig. Great use of a fire alarm hack…though we hope you didn’t use the home one.
  • We appreciate what you’re trying to do: making is a hobby which involves mistakes along the way, and it’s best to carry on without getting discouraged. Just because you haven’t finished, it doesn’t mean that you can’t submit your work to Pioneers and explain what you wanted to do and how. PiCymru‘s We Shall Overcomb did exactly that. We hope you manage to complete your project as we’d love to see it working!

Not forgetting…

Everyone was completely blown away by the projects we saw. And though we couldn’t award every entry a prize, the judges agreed that the following four projects deserved special recognition rewards for their teams:

Electrocuting computer mouse

Our mean boss wouldn’t let this one win (to be fair, we did say not to hurt anyone), but it genuinely made all the Raspberry Pi staff laugh which wins it a dishonourable mention from me. It was also a great hack of an electric fly trap. Well done Team Spark Wire…but maaaaybe try to be a little less lethal with your next submission.

And finally…

To everyone who took part in the first Pioneers challenge, thank you so much for your contributions, and congratulations on everything you achieved. You thrilled us with your tweets, emails, and final submissions, and we hope you also learned some great new skills and possibly made some new friends along the way. Massive thanks to our friends at the Shell Centenary Scholarship Fund for making Pioneers possible. Find out about their awesome work here.

The next Pioneers challenge is…

Shhh! It’s still a secret. We’re not announcing the new challenge until April, so keep your eyes on both the Pioneers website and our social accounts, and sign up to receive the Pioneers newsletter!

Until then, remember to always #MakeYourIdeas.

Particle Flow makes granules tumble in interesting patterns

via Arduino Blog

This Arduino-based project creates interesting tumbling patterns using a system that tilts a plane in a controlled manner while deforming its surface.

NEOANALOG, a “studio for hybrid things and spaces,” was commissioned to build the Particle Flow installation, which explores how granules tumble under the control of gravity. This mechanism takes the form of a large hexagon held in three corners by linkages pushed up and down by NEMA 24 stepper motors. As these rods are lifted, the granules inside the “arena” are steered over to the opposite side producing a zen-like experience.

Inside the main hexagon are 19 smaller hexagons, each controlled by servos to lift an individual section of the rolling surface up and down. Control of the entire system is accomplished via a PC running Processing, which sends commands via Ethernet to an Arduino Mega and the steppers to an Arduino Uno with three motor drivers. 

A moving slanted plane and a grid of motorized stamps control the elements to form infinite variations of behaviors and patterns. The result is a zen-like experience that is both: fascinating and contemplative. Software controlled motion follows a complex choreography and enables precise steering of physical particles in a variety of ways: from subtle to obvious, from slow to high paced, from random-like to symmetric.

The THAT 1206 InGenius and 1646 OutSmarts breakout boards offer an easy solution to adding balanced audio inputs and outputs to your circuits. The THAT InGenius and OutSmarts technologies are designed for high-grade analog audio transmission and reception. They offer low distortion and high common mode rejection in real-world audio applications.

These two breakouts perform mirror-image signal conversion. The 1646 OutSmarts is an unbalanced-to-balanced output driver, and the 1206 InGenius is a balanced-to-unbalanced input receiver.

The breakout boards combine the THAT IC, supporting components and a ¼" TRS socket. They make it easy to use the input and output drivers on breadboards and in projects.

Servo - Hitec HS-5035HD (Ultra Nano Size)

ROB-14210
