JetKVM – A $69 KVM over IP solution with open-source software

We’ve been writing about some low-cost KVM over IP solutions like the Sipeed NanoKVM Cube or GL.iNet Comet in recent times, but the JetKVM has been pointed out to me as another alternative with the benefit of having open-source software (which the NanoKVM also got last month). The JetKVM was launched for $69 on Kickstarter last fall and the crowdfunding campaign was amazingly successful with over 4 million dollars raised from just over 30,000 backers. Key features include 1080p60 video with 30-60ms latency using H.264 encoding, mouse and keyboard emulation, remote management via JetKVM Cloud using WebRTC for accessing the devices from outside the LAN, and open-source software written in Golang on Linux. JetKVM specifications: SoC – Rockchip RV1106G3 CPU – Arm Cortex A7 @ 1.0GHz VPU – H264 & H265 hardware encoder Memory – 256 MB DDR3L on-chip Storage – 16 GB eMMC flash Display – 1.69-inch IPS capacitive […]

The Pebble Smartwatch is back with the Core 2 Duo and Core Time 2 models running PebbleOS open-source firmware

The Pebble Smartwatch was first introduced in 2012 with a black and white e-Paper display, a week of battery life, and an amazingly successful Kickstarter company that raised over 10 million dollars. It was followed by the Pebble Time with a color display in 2015, and the Pebble 2 & Time 2 watches followed in 2016. But then it all went south from there, and Pebble’s assets were purchased by Fitbit in December 2016, all projects were canceled that year, and cloud services were discontinued in June 2018. Since then, the community has taken over working on the Rebble project to keep existing watches running, and Google acquired Fitbit in 2021. However, the project is slowly coming back to life. First, Google released the source code for the Pebble smartwatches and Pebble’s founder, Eric Migicovsky, and a team of engineers worked on reviving the project which now culminates with the […]

MicroPython-programmable OpenMV N6 and AE3 AI camera boards run on battery for years (Crowdfunding)

OpenMV has launched two new edge AI camera boards programmable with MicroPython: the OpenMV AE3 powered by an Alif Ensemble E3 dual Cortex-M55, dual Ethos-U55 micro NPU SoC, and the larger OpenMV N6 board based on an STMicro STM32N6 Cortex-M55 microcontroller with a 1 GHz Neural-ART AI/ML accelerator. Both can run machine vision workloads for several years on a single battery charge. The OpenMV team has made several MCU-based camera boards and corresponding OpenMV firmware for computer vision, and we first noticed the company when they launched the STM32F427-based OpenMV Cam back in 2015. A lot of progress has been made over the years in terms of hardware, firmware, and software, but the inclusion of AI accelerators inside microcontrollers provides a leap in performance, and the new OpenMV N6 and AE3 are more than 100x faster than previous OpenMV Cams for AI workloads. For example, users can now run object […]

PicoCalc Kit is a Raspberry Pi Pico handheld terminal with a backlit STM32 QWERTY keyboard

ClockworkPi has made several Linux handheld terminals over the years such as the GameShell or DevTerm, but the PicoCalc Kit is quite different since it relies on the Raspberry Pi Pico board plus an STM32 microcontroller to handle its built-in keyboard. The PicoCalc Kit is based on the ClockworkPi v2.0 mainboard that takes an RP2040-based Pi Pico H board, connects to a 4-inch IPS display with 320×320 resolution and stereo speakers, integrates a backlit QWERTY keyboard, and ships with a 32GB SD card with an optimized BASIC firmware. PicoCalc Kit specifications: ClockworkPi v2.0 mainboard Compatible boards – Headers for Raspberry Pi Pico H/WH, and Raspberry Pi Pico 2 / 2W MCU – STM32 for keyboard and backlight programmable with the Arduino IDE or STM32 official development tools Storage – SD card slot Display – Screen connector (SPI) Audio 2x speaker connectors 3.5mm audio jack 67-key QWERTY keyboard (I2C) Expansion Connector […]

Home Assistant 2025.3 released with dashboard view headers, tile card improvements, better SmartThings integration

The popular Home Assistant has gotten an update with version 2025.3 that brings dashboard view headers, several tile card improvements, better map clustering, streamed responses from LLMs, and improved SmartThings integrations. Let’s have a look at some of the improvements starting with dashboard view headers which allow users to add a title and welcoming text to dashboards using Markdown and templates. You can also add badges next to the headers. Home Assistant 2025.3 also brings plenty of improvements to tile cards: Adding a circular background around tiles that perform actions, and leaving the ones that just show extra information without a circle Features of a tile card can now be positioned inline in the tile card (e.g. on/off button) New features: switch toggle, counter toggle (to increase, decrease, or reset a counter entity), animations when hovering over atile card Editor improvements for ease of use The new version of Home […]
