DIY Pi KVM: An easy and cheap KVM over IP for Raspberry Pi

Traditional IP-KVM systems may cost you hundreds of dollars. DIY Pi KVM over IP is a very simple and fully functional Raspberry Pi-based KVM over IP that you can make yourself. If you do not know what IP-KVM is, it stands for keyboard, video, and mouse. It allows you to connect to a computer or a server remotely. With this, you can fix problems such as configuring the BIOS or reinstalling the OS using a virtual CD-ROM or flash drive. You can see the v2 example implementation in the above image. Pi-KVM v0 and v2 are ready-made images available for download for Raspberry Pi. You will find all the required hardware in the “Getting Started” section for the v0 and v2 platform for Raspberry Pi. In the figure below you can see the B101 HDMI-to-CSI bridge connected to the Raspberry Pi. The team is working to launch the v3 board and is up for pre-order. Key features It supports Raspberry […]

Official Raspberry Pi 4 case fan adds cooling to Raspberry Pi 4 case

When the Raspberry Pi Foundation first introduced the Raspberry Pi 4, they claimed the board would work just fine under most cases without a heatsink, and the latter was only really needed under load. That may have been true when using the board in a temperate climate like in the United Kingdom, but then Raspberry Pi 4 met Thailand with some benchmarks results lower than on a Raspberry Pi 3. People using plastic enclosures had even more troubles. It’s only when I installed a heatsink on Raspberry Pi 4 that the board could really shine. The company also provided some firmware optimizations later on to further cool-down the board. But you can only do much with software, and many third-party cooling solutions such as fansinks or metal cases have been introduced for the popular SBC. But it appears the Raspberry Pi Foundation is now taking cooling into account, and I was really impressed by the foundation’s latest Raspberry Pi 400 […]

Pi-oT 2 IoT module adds 24V digital inputs, RS-485, and UPS to Raspberry Pi (Crowdfunding)

Pi-oT was launched last year as a Raspberry Pi add-ons designed for commercial and industrial IoT automation. It features 5V I/Os, relays, and ADC  inputs suitable for light-duty projects and prototyping. The company, called Edge Devices, has now launched an update with Pi-oT 2 adding optional support for 24V digital inputs, RS-485, and an uninterruptible power supply (UPS). Pi-oT 2 comes in three variants with the following key features and specifications: SBC support – Raspberry Pi model B boards with 40-pin I/O header Connectivity – Ethernet access via extra port 6x digital outputs 8x analog inputs (0 to 5V), 10-bit precision for Pi-oT 2 and 2 +Plus models, 10-bit precision for Pi-oT 2 Precision variant Model specific features  Pi-OT 2  4x GPIO 5V power supply Pi-oT 2 +Plus 4x GPIO 5V power supply + UPS Pi-OT 2 Precision 4x 24V digital inputs, compliant with IEC-61131-2 standard (instead of 4x GPIO on the standard models) RS-248 interface 5V, 12V, or 24V […]

IKOULA hosts Raspberry Pi 4 “micro server” for 4.99+ Euros per month

Hosting services for Arm single board computers where you pay a monthly fee for a board, and have it hosted in a datacenter with Internet access and easy provisioning have been around for over six years. Last summer, we reported that Mythic Beasts and mini Nodes had added Raspberry Pi 4 hosting plans to their offerings, and others commented there were also other companies. But I’ve just been informed IKOULA, a hosting company based in France, had introduced Raspberry Pi 4 “micro server” hosting plans starting at just 4.99 Euros ex. VAT per month. The hosting plans include the following: Micro server – Raspberry Pi 4 SBC with 4GB DDR4 RAM Storage – 16GB SD card (optional 120 GB SSD) Connectivity – IPV6 only, with IPv4 as an option Bandwidth – 1 Gbit/s Availability – 99.95 % The company offers Raspbian (Raspberry Pi OS), Ubuntu 20.04 32-bit or 64-bit for the services. IPv6 will probably be fine if you’re going […]

DevTerm with ClockworkPi v3.14: a modular, portable computer

After the launch of ClockworkPi GameShell in Q4 2018, now ClockworkPi has come with yet another exciting product. DevTerm is a portable computer that comes with a 6.8-inch IPS screen, a keyboard with 67 keys, and a battery module, all connected to ClockworkPi v3.14 carrier board and a choice of core modules. It will also come with an optional built-in thermal printer. ClockworkPi v3.14 Mainboard and the Core boards The mainboard ClockworkPi v3.14 uses a compact design and comes with a reduced size of 95x77mm. With a modular design, it gives you a choice of “core board” modules for various applications. Moreover, ClockworkPi v3.14 is now compatible with the Raspberry Pi CM3 series, which means that your work on the Raspberry Pi can be “teleported” to a portable terminal without hassle. It has integrated 5GHz WIFI (802.11ac) and Bluetooth 5.0 which makes it suitable for wireless communication applications as well. A high-gain antenna (HGA) increases the signal strength and provides […]

Raspberry Pi 4 V3DV graphics driver achieves Vulkan 1.0 conformance

Just a couple of weeks ago, we reported on the status of Raspberry Pi 4 Vulkan driver & future plans based on a presentation made by Igalia at the Open Source Summit 2020 at the end of October. At the time, the V3DV Vulkan Mesa driver for Raspberry Pi 4 was merged into Mesa, passed over 100,000 tests in the Kronos Conformance Test Suite (CTS), and was said to implement the full Vulkan 1.0 API. So it should come as no surprise that Khronos has now declared the Raspberry Pi drivers to be conformant with Vulkan 1.0 specifications. This was tested in Raspberry Pi OS with Linux 5.4.51 using X11 display server at 1920×1080 resolution on Raspberry Pi 4. Vulkan 1.0 conformance means the V3DV Mesa driver has passed all tests from Khronos CTS and should be compatible with most applications using this version of the API. The drivers will work on all Broadcom BCM2711 platforms including Raspberry Pi Computer […]

Raspberry Pi 400 kit ships with 7-inch or 13.3-inch touchscreen display

The Raspberry Pi Foundation has recently launched the Raspberry Pi 4 keyboard computer with impressive performance thanks to a well-designed cooling solution, and I think it’s a great tool for kids (and adults) who may want to carry a Raspberry Pi around. However, you’d still need a display in each location, so until the foundation releases the Raspberry Pi 4000 laptop next year (full disclose: I made that up!), it might be cool to have a portable display coming with the keyboard PC. That’s what Waveshare is offering with two kits combining a Raspberry Pi 400 together with a 7-inch or 13.3-inch HDMI touchscreen display and other accessories. Not quite as portable as a laptop but it gets close. Here’s the full list of accessories in the kits: Raspberry Pi 400 Kit with keyboard PC with UK keyboard (sadly the only layout option for now), power supply, HDMI cable, preloaded microSD card with Raspberry Pi OS, mouse, and Beginner guide.
