  • Open Source Innovation Could Put a 3D Bioprinter in Your Living Room

    3D bioprinting traditionally requires high-level expertise, proprietary technology and a five-figure investment. A team of researchers from Carnegie Mellon University setout to change all that. In a paper published earlier this month in HardwareX, the group released the design of a fully functional 3D bioprinter it built by altering a widely available desktop 3D machine. The team’s innovation could be a game changer in terms of the overall accessibility of bioprinting.

  • 3D Printing the SynDaver Open-Source Healthcare Mannequin

    As desktop 3D printers become more robust, reliable, and feature-rich, we are seeing a definite shift in professional use-cases from prototyping to producing final products.

  • Unlock & Talk: Open Source Bootloader & Modem

    Since [Tom Nardi] introduced Hackaday readers to postmarketOS, the team has made progress on compiling a standard bootloader for MediaTek System-on-Chip (SoC) processors. Many Android phones use the MIT-licensed Little Kernel as the base of their bootloader and then apply custom closed-source modifications. [McBitter] has worked to eliminate this closed-source code by porting Little Kernel to the MT6735P used in the Coolpad Modena 2. By understanding the modifications MediaTek used for this particular SoC, the postmarketOS team hopes to use their modified, open-source Little Kernel bootloader with other MediaTek-based devices. While progress has been difficult and attempts at using emulators to probe bootloader memory have failed, [McBitter] was able to decode the DRAM configuration settings by searching for a leaked portion of the configuration strings. Now that he can set up the DRAM, there should be few barriers to running Little Kernel.

Single-unit version of Odroid-MC1 cluster computer adds flexibility

Hardkernel has launched a stackable single-unit Solo version of its 4-board Odroid-MC1 cluster computer. The system runs Linux on a octa-core Samsung Exynos5422 based Odroid-XU4S SBC.

Hardkernel has spun a single-unit version of its four-unit, 32-core Odroid-MC1 cluster computer for running Docker Swarm, Build Farm, and other parallel computing applications. The octa-core Odroid-MC1 Solo costs $48 instead of $220 for the original. The design offers greater flexibility, enabling users to combine Odroid-MC1 Solo units for a “single unit, 2, 3, 4, 5, 6, or n stackable cluster” or combine one or more Solo units with the original 4-unit MC1 to act as a single cluster,” says Hardkernel.

Calamares Pinebook

Hardware

But there is an under-appreciated bit regarding images for an ARM laptop — or pre-installed Linux distro’s in general. And that’s the first-run experience. The Netrunner Pinebook image is delivered so that it boots to the Plasma 5 desktop, no passwords asked, etc. The user is called “live”, the password is “live”, and nothing is personalized. It’s possible, though not particularly secure, to use the laptop this way in a truly disposable fashion. A first-run application helps finalize the configuration of the device by creating a named user, among other things.

One of the under-documented features of Calamares is that it can operate as a first-run application as well as a system installer. This is called “OEM Mode“, because it’s of greatest interest to OEMs .. but also to distro’s that ship an image for users to flash onto (micro)SD card for use in a device.

While some IoT devices can be evaluated from a purely software standpoint (perhaps reverse engineering the mobile application is sufficient for your needs), a lot more can be learned about the device by interacting with all the interfaces available (often including ones not intended for access, such as debug and internal interfaces).

Kontron’s “ACE Flight 1600 Gateway Router” avionics computer runs Linux on a Bay Trail Atom, and provides a 5-port, L2-managed GbE switch, 4G LTE Advanced-Pro, 802.11ac, and DO-160G compliance.

Kontron’s has added to its ACE Flight product line with a compact low-end router computer designed for small commercial jets and business jets. The fanless ACE Flight 1600 Gateway Router is a small form factor avionics networking platform that consolidates wireless connectivity, switching, routing, and security features. “A typical routing application is the secure interface from client devices onboard the aircraft to SATCOM or Air-To-Ground connectivity links,” says Kontron.

University students create award-winning open source projects

In my short time working for Clarkson University, I've realized what a huge impact this small university is making on the open source world. Our 4,300 student-strong science and technology-focused institution, located just south of the Canadian border in Potsdam, New York, hosts the Clarkson Open Source Institute (COSI), dedicated to promoting open source software and providing equipment and support for student projects. While many universities offer opportunities for students to get involved in open source projects, it's rare to have an entire institute dedicated to promoting open source development. COSI is part of Clarkson's Applied Computer Science Labs within the computer science department. It, along with the Internet Teaching Lab and the Virtual Reality Lab, is run by students (supported by faculty advisers), allowing them to gain experience in managing both facilities and projects while still undergraduates.

Linux 4.17-rc2

So rc2 is out, and things look fairly normal. The diff looks a bit unusual, with the tools subdirectory dominating, with 30%+ of the whole diff. Mostly perf and test scripts. But if you ignore that, the rest looks fairly usual. Arch updates (s390 and x86 dominate) and drivers (networking, gpu, HID, mmc, misc) are the bulk of it, with misc other changes all over (filesystems, core kernel, networking, docs). We've still got some known fallout from the merge window, but it shouldn't affect most normal configurations, so go out and test. Linus Read more Also: Upstream Linux support for new NXP i.MX8
