I'm looking for  a $1 single board computer or controller that can control 60 LEDs, a buzzer, 2 three digit seven segment displays and one buzzer.  This controller must be acurate to a second. is there such a controller?  Is there a controller or a group of components in this cost range? ...
Introduction I recently needed a small form-factor computer and I was lucky enough to get given an Intel NUC (model NUC7i3DNKE) as part of my work. I thought I’d take some photos of it as I explored it.   My primary use-case will be to use it for demos. It is very small so it can be taken with me when I travel. However, there are other uses planned for it too.   In the drive for a silent environment to work in, I hardly ever turn on the desktop PC. The laptop works fine for m ...
NASA to send robotic bees to Mars in an attempt to study the planet further. The space agency has implemented this idea ahead of sending humans to our neighbor planet. The image shows a concept of how Marsbees would work. (Photo via NASA)   What’s the next step after Mars rovers? Swarms of robots!   Dubbed “Marsbee,” a swarm of robotic bees are being planned to boost and support a central rover. The rovers have some limited capacities in their technology, but that ...

Raspberry Pi 3

Posted by colonel_dirty Mar 10, 2018
Salutations I am a student at Northern Arizona University,       I am currently a participating in a robotics competition. I have a degree in Mechanical engineering and I am currently pursuing a second degree in computer science. The robot we are making for the competition is a soccer playing robot this is my first time doing programing like this. I have an understanding in Python and Java. We are using a Raspberry Pi 3 for the brains of the robot. I have installed Ras ...
Introduction The Leap Motion Controller is something that can be used as an input device for a computer (desktop/laptop or a single board computer). It can be placed on the desk, or if desired can be strapped onto a virtual reality (VR) headset if you have one. In brief, when it sees your hand or hands, it can analyse them to figure out where your fingers, palms and so on, are in three dimensional space. It can also figure out certain movements such as swipes. You could use it for controlling st ...

hi all i am not new to eletronics but i am new to microcontrolers and sbc but i was wondering were do i start in building my own sbc i know you need the basics the prosesor ram rom and mic parts ...
I finally purchased a couple of PocketBeagles, I knew they would be small, but it is still amazing to see it close-up! It is very thin too, it measured 4.60mm (the highest point is the surface of the Octavo module). For connections, I purchased 2x9way total 18-way header pins because these are cheaper than 2x18way. A total of four of these are needed to fully connect to the PocketBeagle, although that might not be necessary for all projects. Note that the header pins are connected to the u ...
The Volocopter saw its first tethered passenger flight during CES 2018. (Image credit: Volocopter)   German drone manufacturer Volocopter recently demonstrated its first manned flight at this year’s CES, of course, it was tethered and indoors but it’s still a milestone never the less. With the onset of autonomous vehicles, it was only a matter of time before autonomous drones transitioned into pilotless taxis set to enter into service sooner than we might think.   The Vol ...
The seventh successful launch of Blue Origin’s New Shepard reusable suborbital spacecraft. (Image credit: Blue Origin)   The Skywalker’s have always been a family of many talents- young Anakin became a notable Sith Lord, his son Luke became a Jedi Knight, his daughter lead a great Rebellion
ot-so-great Resistance, and distant cousin Mannequin made it through a successful test flight aboard a reusable suborbital spacecraft. “Always two there are; no more, no less-” ...
While the city won’t be outright banning these bots, they are now not allowed on crowded city sidewalks. These bots have a lot of rules to follow before they hit the streets (Image via Reuters)   When it was first introduced, the idea of delivery robots sounded absurd. Now, it’s close to becoming a reality, but maybe not in San Francisco. Companies are currently testing out these bots, but are hitting a road block when it comes to San Fran. Recently, the city’s Board of S ...
Google’s AutoML utilizes reinforcement learning to build superior versions of itself.   Earlier this year (May 2017), the Google Brain Team unveiled their AutoML AI (Artificial Intelligence) platform capable of creating its own AIs. Moving forward, the Team recently announced that the same AI platform has succeeded in creating an offspring (or child) that has outperformed anything made by Google engineers. AutoML used deep learning to build the new AI, which uses multiple layers of ...
The needle is cost effective and allows doctors to see targeted tissue that’s normally difficult to spot during procedures. If you have trypanophonia you may want to look away. (Photo via Nature)   No one ever looks forward to having surgery, but if it has to be done, minimally invasive procedures are more appealing. Usually, they leave less scar tissue, have a quicker recovery time, and have a lower risk of infection. But there are also several downsides, like getting a detailed loo ...
These new artificial muscles not only prove to be strong, but are also easy to make and cost effective. Though it looks like a snake made in origami, it’s actually a new soft robot (Photo from MIT CSAIL)   Because soft robotics are flexible, it allows these machines to move in ways similar to living organisms. The only problem is the more flexibility these bots have, the more their strength is reduced. This may no longer be an issue thanks to a new discovery from MIT scientists. A te ...
Note: This blog post partly contains some new content, and partly some content from blog posts I’ve written in the past. It is a consolidation, to make information relevant to FRDM boards and mbed available at one convenient location.   Introduction FRDM boards are a range of compact (slightly larger than credit-card sized) boards with a microcontroller. They are great for prototyping projects. The FRDM boards and the mbed platform (described later) are designed to make users concent ...
Boston Dynamics Atlas robot can now jump and perform backflips on its own without assistance. (Image credit Boston Dynamics)   Boston Dynamics’ Atlas has come a long way since it was first developed back in 2013 as a spin-off of the company’s earlier PETMAN robot. Back then, the mechanical monstrosity had to be tethered to a bulky power supply and used an overhead crane for safety purposes as it had a tendency to fall down a lot. DARPA Program Manager Gill Pratt emphasized that ...
