Hackaday ☛ 256-Core RISC-V Megacluster
Supercomputers are always an impressive sight to behold, but also completely unobtainable for the ordinary person. But what if that wasn’t the case? [bitluni] shows us how it’s done with his 256-core RISC-V megacluster.

CNX Software ☛ Arduino Pro Opta D1608E/D1608S expansions feature electromechanical or solid-state relays, 16 I/Os
Arduino has recently announced two new expansions to their Arduino Pro Opta PLC series – the Arduino Pro Opta Ext D1608E and Arduino Pro Opta Ext D1608S, the main difference between the two is that the D1608E features 8 electromechanical relays (EMRs) whereas the D1608S features solid-state relays (SSRs). Other than that both expansion modules have 16x programmable I/Os (0-24 V digital / 0-24 V analog) which doubles the number of I/Os we have seen on the Opta micro PLC.

Raspberry Pi ☛ Compute Module 4 brings Sega Game Gear back to life
Compute Module 4 is running RetroPie inside a salvaged Game Gear handset, giving the user access to as many classic games as the innards of their machine will allow. Jeff explains in his build video that he could have used a Raspberry Pi Zero 2 W or a 3A+, which would draw less power but wouldn’t be quite as fast.

Raspberry Pi ☛ Meet André Costa: the brains behind rpilocator — The MagPi magazine
The service we now know as rpilocator started off as cm4locator, with André coding it during a couple of days off. Initially it was private, and within a couple of days it had helped him locate – and buy – a Raspberry Pi Zero 2 W. Surprised at how easy it was, he decided to make a public version.

Raspberry Pi ☛ Retro printer — The MagPi magazine
Having talked with two fellow electrical engineers, he tried in vain to work out a low-cost solution. “It was only with the release of the earliest Raspberry Pi that I realised an affordable printer emulator could be developed,” he says. This prompted him to begin work on the Retro-Printer project – a HAT designed to plug into a Raspberry Pi computer that allows data captured from the Centronics (or parallel) port on a retro machine to be sent to a modern printer.
