Arduino Blog » Bikelangelo is a water-dispensing graffiti bicycle trailer
Inspired by persistence of vision (POV) projects, Sagarrabanana built a system that incrementally dispenses water as pixels on a flat surface, creating ephemeral dot matrix text/images. This so-called “Bikelangelo” device is towed by a bicycle for ultra-mobile marking, and uses a pressurized tank for fluid storage.
As he pedals, a series of seven valve open and close under Arduino Nano control. A Hall-effect sensor allows it to dispense accurately based on the bike’s speed, and a Bluetooth phone connection via an HC-05 module is implemented for text input on-the-go.

Fuzix Unix-like operating system ported to Raspberry Pi Pico and ESP8266
The Raspberry Pi Pico is not compatible with Linux, but now supports another Unix-like operating system known as Fuzix. Alan Cox’s Fuzix is a Unix-like operating system for older devices with less performance capacity. David Given’s two recent posts have brought to the attention about the operating system’s compatibility with ESP8266 MCU and Raspberry Pi Pico. Fuzix operating system has a kernel which is the central core of the system.

Elkhart Lake arrives on thin Mini-ITX
Advantech’s Linux-friendly “AIMB-218” thin Mini-ITX board ships with Elkhart Lake SoCs including a new 2GHz/3GHz Pentium J6426 plus 32GB DDR4, 2x GbE, 3x USB 3.2 Gen2, DP and HDMI, 2x M.2, SATA, and PCIe x1 Gen3.
Advantech announced the AIMB-218, the first thin Mini-ITX board we have seen equipped with Intel’s next-gen Atom platform, Elkhart Lake processors. Yet, we now see that DFI has posted a preliminary product page for EHL171 and EHL173 thin Mini-ITX boards with dual 2.5GbE ports, but with scant details and no listed OS support.
MiTac, meanwhile, has posted a more detailed product page on a PD10EHI thin Mini-ITX board that runs Windows, with Linux available on request. Unlike Advantech’s entry, neither board has been formally announced. We may report on these later.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe 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. |
