“Teensy” Arduino clone grows, with more I/O, USB, and faster CPU

Filed under
Hardware

PJRC is Kickstartering two new models of its “Teensy” Arduino compatible, featuring a faster 180MHz Cortex-M4, more memory, more pins, and a second USB.

In the world of Arduino compatibles, you can choose from bare-bones clones or value-added innovators that develop new software as well as hardware, and occasionally risk some compatibility in order to advance the capabilities of the entire Arduino platform. In the latter category is Teensy, a DIY breadboard-oriented Arduino project from Portland, Oregon based PJRC, led by Teensy inventor Paul Stoffregen, known for its superior USB-based keyboard/mouse, LED array, and audio support. The eight-year old company has now upgraded the Teensy board with a much faster MCU, more RAM and flash, many more I/O pins, and additional USB and CAN ports, making it one of the fastest Arduino clones around.

  • Intel “Aero” drone board runs Yocto on Cherry Trail

    Intel has launched a Linux-on-Atom powered “Aero Compute Board” and quadcopter, promising improved obstacle navigation based on Intel RealSense.

    Even more than last year’s Intel Developer Forum, this week’s IDF is focusing relentlessly on Intel RealSense. The 3D depth sensing camera technology is everywhere at IDF, including the new Windows-focused Project Alloy VR helmet and several Linux-infused drone, robotics, and camera kits. In fact, even the new Kaby Lake and Apollo Lake processors expected to be announced today include built-in support for RealSense. Here, we take a look at the Intel Aero Platform drone products: the Atom-based Intel Aero Compute Board and an Aero Ready To Fly quadcopter based on it.

Ubuntu

The original Raspberry Pi sparked the creativity of many developers and students, but it was woefully underpowered. Through several iterations, however, it slowly became more powerful. While the most recent version -- the Raspberry Pi 3 -- has a much more capable processor, some developers will still want even more horsepower.

Today, Intel announces a maker board that puts the Raspberry Pi 3 to shame. The Joule system-on-module mini-computer features RealSense camera support and runs Ubuntu Linux Core. Best of all, its specs are very impressive for what it is.

  • Qubie is an open hardware solution for tracking wait times at voting places

    With an incredibly important national election coming up, it’s more critical than ever that everyone who can vote does — and is able to. Election tech firm Free and Fair is hoping to help avoid overflowing voting locations with a simple, open source device that automatically monitors waiting times and keeps voters and officials informed.

    Free and Fair creates open source software for polling places, from checking in voters to actually taking and tallying votes — but Qubie is the company’s first original hardware, created for the Hackaday Prize. Founder Daniel Zimmerman explained that it was just another aspect of the voting process that struck them as out of date.

    “In the last few elections there have been reports of long queue times, people giving up and going home,” he told TechCrunch. “Election technology is in a pretty sorry state — we thought it’d be nice to gather data on that rather than anecdotes.”

  • Kernel.org Is Knocking On The Door Of My Odroid-C2

    If this ~$100 CDN tiny box pleases TLW, it’s Good Enough. When a proper video driver gets into Linus’ mainline, say, with Wayland, and distros have all the usual applications working, these things will take over. It surely blows away her old VIA box with 8 core-gHz CPU, gigabit/s networking and 2gB RAM compared to 0.4 core-gHz, 100 mbits/s, and 0.25gB RAM. We’re using files over NFS so TLW will be able to use her old desktop environment on Beast III if she wants. Otherwise, she can use the Odroid-C2 as a thick client well enough. Cost for the old ones was ~$150 CDN delivered a decade ago, with real money, not this inflated stuff. Life is good.

  • AArch64 desktop hardware?

    Soon there will be four years since I started working on AArch64 architecture. Lot of software things changed during that time. Lot in a hardware too. But machines availability still sucks badly.

    In 2012 all we had was software model. It was slow, terribly slow. Common joke was AArch64 developers standing in a queue for 10GHz x86-64 cpus. So I was generating working binaries by using cross compilation. But many distributions only do native builds. In models. Imagine Qt4 building for 3-4 days…

    In 2013 I got access to first server hardware. With first silicon version of CPU. Highly unstable, we could use just one core etc. GCC was crashing like hell but we managed to get stable build results from it. Qt4 was building in few hours now.

  • RISC-V on an FPGA, pt. 1

    Last year I had open source instruction set RISC-V running Linux emulated in qemu. However to really get into the architecture, and restore my very rusty FPGA skills, wouldn’t it be fun to have RISC-V working in real hardware.

    The world of RISC-V is pretty confusing for outsiders. There are a bunch of affiliated companies, researchers who are producing actual silicon (nothing you can buy of course), and the affiliated(?) lowRISC project which is trying to produce a fully open source chip. I’m starting with lowRISC since they have three iterations of a design that you can install on reasonably cheap FPGA development boards like the one above. (I’m going to try to install “Untether 0.2” which is the second iteration of their FPGA design.)

    With its customizable, open-source SoCs built on the free and open RISC-V instruction set architecture, SiFive, a San Francisco start-up, is poised to reverse the industry’s rising licensing, design and implementation costs.

    With on the one hand Moore’s Law ended or approaching the end and on the other, vast investments required for to develop a modern, high-performance chip, it looks impossible for smaller system designers to join the traditional economic model of chip building. However, the body of software and tools available from the open-source community under the guidance of the RISC-V Foundation, can substantially cut the cost of developing custom silicon. System designers can use the SiFive Freedom platforms to focus on their own differentiated processor without having the overhead of developing a modern SoC, fabric or software infrastructur

    Unless you’ve been living under a rock, you heard that some researchers managed to create a SHA-1 collision. The short story as to why this matters is the whole purpose of a hashing algorithm is to make it impossible to generate collisions on purpose. Unfortunately though impossible things are usually also impossible so in reality we just make sure it’s really really hard to generate a collision. Thanks to Moore’s Law, hard things don’t stay hard forever. This is why MD5 had to go live on a farm out in the country, and we’re not allowed to see it anymore … because it’s having too much fun. SHA-1 will get to join it soon.

  • Red Hat: 'use after free' vulnerability found in Linux kernel's DCCP protocol IPV6 implementation
    Red Hat Product Security has published details of an "important" security vulnerability in the Linux kernel. The IPv6 implementation of the DCCP protocol means that it is possible for a local, unprivileged user to alter kernel memory and escalate their privileges. Known as the "use-after-free" flaw, CVE-2017-6074 affects a number of Red Hat products including Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7 and Red Hat Openshift Online v2. Mitigating factors include the requirement for a potential attacker to have access to a local account on a machine, and for IPV6 to be enabled, but it is still something that will be of concern to Linux users. Describing the vulnerability, Red Hat says: "This flaw allows an attacker with an account on the local system to potentially elevate privileges. This class of flaw is commonly referred to as UAF (Use After Free.) Flaws of this nature are generally exploited by exercising a code path that accesses memory via a pointer that no longer references an in use allocation due to an earlier free() operation. In this specific issue, the flaw exists in the DCCP networking code and can be reached by a malicious actor with sufficient access to initiate a DCCP network connection on any local interface. Successful exploitation may result in crashing of the host kernel, potential execution of code in the context of the host kernel or other escalation of privilege by modifying kernel memory structures."
