Raspberry Pi 400 powers dual-display retro-gaming console

“Block after Block” has designed a dual-display tabletop retro-gaming console using plywood edge grain and a Raspberry Pi 400 keyboard PC that allows players to physically face each other during a fight or other gameplay. While there’s a galore of projects based on Raspberry Pi SBCs, the Raspberry Pi 400 keyboard PC is more like a consumer product due to its form factor, but Block after Block integrated the PC into its own retro-gaming console which involved a lot of woodworking skills and installing RetroPie on the Pi 400 device. This DIY project mostly involves spending time in a workshop cutting wood, and once you’re done with this part, it should be pretty straightforward. The following items are required for the project: A Raspberry Pi 400 keyboard PC Two monitors (second-hand monitors will do) An HDMI splitter to mirror the output from the Pi 400 along with a micro HDMI […]

Control 8 relays with the Raspberry Pi Pico using PicoRelay8 or Pico-Relay-B

Waveshare Pico Relay B with Raspberry Pi Pico board

8086 Consultancy’s PicoRelay8 is a baseboard for the Raspberry Pi Pico (W) board equipped with eight 28V DC / 10A Normally Open relays that be used for all sorts of automation projects, while Waveshare Pico-Relay-B also supports eight relays with both DC and AC loads and comes with some extra features. PicoRelay8 PicoRelay8 board specifications: Supported MCU board – Raspberry Pi Pico or Pi Pico W, and it may also work with “mostly” compatible boards such as the Banana Pi BPI-Pico-RP2040 or BPI-PicoW-S3, WeAct RP2040, and others as long as all GPIO used on the PicoRelay8 are exposed on the same pins. Relays 8x HF3FF/005-1HST relays rated for 28V DC/10A, as well as 10A/250V AC and 15A/125V AC, but the board is not designed to get power from the mains (safety-wise), so it’s only really suitable for DC loads Each relay has a 2-pin terminal block attached to it. GPIO […]

Install a server in your house, get free hot water!

Heata, which began as an innovation project with British Gas, is a UK company that connects a server to your hot water cylinder and provides hot water to the house master for free up to 4.8 kWh per day, and at least 2.5 kWh as per contractual obligations. Companies spend millions of dollars to cool the servers hosted in their data centers and most of that heat is completely wasted. So Heata decided to create a win-win solution that lowers their cooling cost and provides free hot water to whoever has their server installed in their house. The installation process is said to be tested and approved by British Gas so you don’t lose your hot water cylinder warranty, and the heat transfer mechanism is patented as well under the UK patent GB2576035. A technician would come to cut the insulation and attach a thermal bridge to the cylinder. The […]

2.5Gbps SFP to RJ45 Ethernet adapter sells for $25 shipped

Banana Pi has started selling an inexpensive 2.5Gbps SFP to RJ45 adapter for their Banana Pi BPI-R3 WiFi 6 router board that goes for $17.89 plus shipping ($25 shipped here) on Aliexpress. The BPI-R3 router includes five Gigabit Ethernet RJ45 ports as well as two 2.5GbE SFP cages, but since not everybody has equipment that takes SFP cables, they used to sell it with a $30 TP-Link adapter. The company now appears to have found a cheaper model marked “SFP-2.5G-T” module that works with their board. It’s designed to be inserted into one of the 2.5GbE SFP cages and provide a more common 2.5GbE RJ45 port to the user. There’s very little information about the module except its designed with an up to 100-meter cable, and the serial number BT2211010016 only points to Banana Pi’s Wiki. But I don’t think the company designed its own adapter and found another Wiki […]

USB Cereal is an open-source hardware USB-C debugging & development tool (Crowdfunding)

0xDA LLC’s USB Cereal is an open-source hardware development tool with three USB-C ports designed to simplify the testing, development, debugging, and manufacturing of devices with USB Type-C ports. Initially originated at Google, the USB Cereal project has gone through multiple revisions to optimize its quality and lower the BoM cost, and the device can be used for all sorts of USB Type-C debugging using a UART serial communication with the host device through the USB-C sideband use (SBU) pins typically reserved for device-specific applications. USB Cereal specifications: USB Type-C ports 2x USB-C ports for passthrough between the host and device under test (DUT) Note: the DUT port is on the side with a single USB Type-C connector No orientation detection has been implemented to keep the design as simple and inexpensive as possible 1x USB-C port for capture support to 3 Mbps connected through FTDI FT232RNQ USB to TTL […]
