rpi-image-gen build system creates custom images for Raspberry Pi boards

Raspberry Pi has just released the rpi-image-gen build system to generate custom Raspberry Pi images designed for a specific application and based on packages from the Debian and Raspberry Pi OS repositories I was initially surprised by this announcement, as there are already build tools like the Yocto Project or buildroot designed for this purpose. They are however somewhat complex to use and there’s a steep learning curve, so maybe Raspberry Pi made something easier to use. Let’s have a look. The build is mostly defined by a configuration file which defines the profile and image layout. The company explains the main reasons for creating yet another build system. First, the images are quick to build with the rpi-image-gen build system since you don’t have to build the whole project from source, contrary to something like the Yocto Project which can take hours (for the first build at least). That’s […]

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 […]

Mini UPS with 5V, 9V, 12V DC, and PoE output could be useful for routers, security cameras, SBCs, and mini PCs

Mini Uninterruptible Power Supply DC USB PoE

Most uninterruptible power supplies (UPS) require AC voltage and use specific batteries that must be changed every few years. But those may be oversized and not the most efficient if you just want to keep single board computers (SBCs), low-power mini PCs, routers, or security cameras up and running during power failures. Luckily, some mini UPS solutions use standard rechargeable 18650 batteries, output 5V, 9V, or 12V DC, or even PoE (15V/24V) which may be more suitable for those use cases. Many mini UPS solutions come from WGP (Wonderful Green Power), so let’s have a look at the WPG103A model. WPG103A mini UPS specifications: Batteries – 4x 18650 batteries for a combined 10,400 mAh capacity Protection – Overcharge, over-discharge, overcurrent, and short circuit protection Misc – Power button, status LEDs Power Input – 12V/2A via DC jack Power Output 5V via USB Type-A port (likely limited to 1.5A or 2A […]
