FOSSASIA 2025 – Operating systems, open hardware, and firmware sessions

FOSSASIA Summit 2025

The FOSSASIA Summit is the closest we have to FOSDEM in Asia. It’s a free and open-source event taking place each year in Asia, and FOSSASIA 2025 will take place in Bangkok, Thailand on March 13-15 this year. It won’t have quite as many speakers and sessions as in FOSDEM 2025 (968 speakers, 930 events), but the 3-day event will still have over 170 speakers and more than 200 sessions. Most of the sessions are for high-level software with topics like AI and data science, databases, cloud, and web3, but I also noticed a few sessions related to “Hardware and firmware” and “Operating System” which are closer to what we cover here at CNX Software. So I’ll make a virtual schedule based on those two tracks to check out any potentially interesting talks. None of those sessions take place on March 13, so we’ll only have a schedule for March […]

FluidNC-compatible CNC controller supports 6 stepper drivers, web-based configuration

6x CNC A FluidNC compatible CNC controller

US-based CNC and motion control developer Bart Dring has designed the 6x CNC Controller FluidNC-compatible CNC controller board built around an ESP32 (pre-programmed with FluidNC) module and including 6 external stepper motor drivers with 5V signals.

Tobor open-source, modular robotic arm features two ESP32 modules (Crowdfunding)

Tobor robotics platform with pen plotter toolhead

Tobor (robot spelled in reverse) is a modular and open-source robotic arm platform powered by the ESP32-WROVER-I and ESP32-WROOM-32 (FluidNC CNC Controller core) modules. It is described as a “fully-featured robotic system that can fit on your desktop and is capable of helping you automate your workflow.” Tobor is billed as a customizable assistant for complex tasks such as assembly line help, CNC design, and rapid prototyping. The Tobor ecosystem includes several open-source components, including robotic arms, motion platforms, sensors, and actuators, that can be combined to create a unique system for “almost any desktop automation.” The Tobor Robot Arm supports multiple toolhead options such as the pen plotter toolhead, z-stage toolhead with 4th axis and suction cup, and the pick and place expansion pack. We have seen other open-source robotic platforms such as the SO-ARM100 AI robotic arm kit, CYOBot v2, and MIKRIK V2 Robot Car. Tobor Robot Arm […]

BANDIT PC32 standalone ColorForth keyboard computer is powered by the Raspberry Pi RP2350 microcontroller

BANDIT RP2350 computer

BANDIT PC32 is a Raspberry Pi RP2350-powered keyboard computer that runs a graphically-oriented version of the ColorForth programming environment. The BANDIT PC32 is primarily aimed at on-the-go use for programming video games. The custom, 32-key split keyboard takes up most of the build, with a 3.2-inch 320 x 240 capacitive display in the center. It also features an HDMI port for connecting a larger external display. The 48-pin GPIO is divided into two female headers and can be used to interface with other devices directly. This is the second version of the Bandit standalone computer, building on an early prototype based on the RP2040 microcontroller. We have seen several interesting RP2350-based products like the Inky Frame 7.3”, 4D Systems display modules, and Jumperless V5 programmable breadboard. However, this is the first RP2350 standalone computer we have come across. It shares some similarities with the ESP32 Rainbow. BANDIT PC32 ColorForth specifications: […]

Jack Dorsey talk at FOSDEM 2025 may lead to protest

FOSDEM 2025 protest

Jack Dorsey, who previously owned Twitter and now runs Block, will be giving a talk at FOSDEM 2025 entitled “Infusing Open Source Culture into Company DNA: A Conversation with Jack Dorsey and Manik Surtani, Block’s head of Open Source” and some people don’t like having a billionaire giving a talk at an open-source event and plan to host a protest. I recently wrote about my own FOSDEM 2025 schedule focusing on embedded systems topics, and while the event is usually non-controversial, I was startled by a tweet by FOSDEM organizers who issued a “statement on planned protests during the upcoming FOSDEM 2025”. I eventually found out that it was related to a post by Drew DeVault who did not appreciate having a billionaire talk during the open-source-focused event. The talk is planned in the Janson venue which is the biggest at the event with a capacity of up to 1,500 […]
