  • Jabil Offers Complete Source for Engineered Materials for 3D Printing
  • Manufacturing Bits: Jan. 22

    Using open-source designs and off-the-shelf components, researchers have developed an automated CVD system for $30,000 in hardware costs, according to Boise State in the journal PLoS One.

  • Building A 3D Printer That Goes Where You Do

    Given the wide array of very popular low cost 3D printers out there, some will likely be surprised that [Thomas] decided to mobilize a printer which is nearly an antique at this point: the PrinterBot Play. But as he explains in the video after the break, the design of the Play really lends itself perfectly to life on the road. For one, it’s an extremely rigid printer thanks to its (arguably overkill) steel construction. Compared to most contemporary 3D printers which are often little more than a wispy collection of aluminium extrusion and zip ties, the boxy design of the Play also offers ample room inside for additional electronics and wiring

    The most obvious addition to the PrintrBot is the six Sony NP-F camera batteries that [Thomas] attaches to the back of the printer by way of 3D printed mounts, but there’s also quite a bit of hardware hidden inside to break the machine free from its alternating current shackles. The bank of batteries feed simultaneously into a DC boost converter which brings the battery voltage up to the 12 V required for the printer’s electronics and motors, and a DC regulator which brings the voltage down to the 5 V required by the Raspberry Pi running OctoPrint. There’s even a charge controller hiding in there which not only frees him from carrying around a separate charger, but lets him top up the cells while the printer is up and running.

  • Open Source Synthesizers Hack Chat

    Matt Bradshaw is a musician, maker, and programmer with a degree in physics and a love for making new musical instruments. You may remember his PolyMod modular digital synthesizer from the 2018 Hackaday Prize, where it made the semifinals of the Musical Instrument Challenge. PolyMod is a customizable, modular synthesizer that uses digital rather than analog circuitry. That seemingly simple change results in a powerful ability to create polyphonic patches, something that traditional analog modular synths have a hard time with.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
