This RaspberryPi project uses weather data to estimate the share of renewable energy in the power grid

This RaspberryPi project uses weather data to estimate the share of renewable energy in the power grid.From this, the value of CO2 emissions per kWh can be calculated.Visit https://www.agora-energiewende.de/service/agorameter/ for an overview of the electricity mix and the emission value. The estimated emission value is displayed similar to a traffic light on a green-red scale by leds connected to the RaspberryPi. GitHub View Github

A Raspberry Pi Powered Barcode Reader to load a game on the Mister FPGA using MBC

A Raspberry Pi Powered Barcode Reader to load a game on the Mister FPGA using MBC This is a work in progress and a bit hackery 😅 There are limitations on the MBC side. Some of the computer cores don’t work in loading games up. Such as the commodore computers as the cores have changed the menu layout is slightly different. Currently i have only implemented getting games from out of zip files. You can do direct loading of a […]

Play music on Raspberry Pi Pico Without CPU involvement

Play music on Raspberry Pi Pico Without CPU involvement This is based on PIOBeep (https://github.com/benevpi/pico_pio_buzz) but lets you setup a piece of sound and then play it without processor involvement. It’s a little RAM intensive (circa 2K per second). It might be possible to improve this but might not. The DMA transfer is running as slowly as it can. I suppose slowing down the clock frequency would decrease RAM useage, but that probably defeats the point. It’s probably possible to […]
