Then a look at an open-hardware "zero-power" badge, based around the Raspberry Pi RP2040. The trick: it's "zero-power" for its core functions, thanks to a passive NFC chip and an ePaper electrophoretic display. If you want to use the microcontroller, *then* you need power. https://www.hackster.io/news/kai-pereira-s-ticket-shaped-raspberry-pi-rp2040-powered-badge-boasts-a-zero-power-design-0cf05393a18b #Technology #News #Hackster #OpenHardware

And finally, the SediCi PC - a retro-styled microcomputer implemented on a low-cost #FPGA, and built around a custom 16-bit CPU. Yes, you can download the Verilog. https://www.hackster.io/news/alexey-frunze-s-sedici-pc-is-a-16-bit-microcomputer-on-an-fpga-with-a-custom-built-cpu-c0637c1a64ea #Technology #News #Hackster #OpenHardware #OpenSilicon
