Bob Davis has been working on an 8×8 RGB LED array with a Raspberry Pi project: I have been working on a book of Raspberry Pi projects. One of the projects is an 8×8 three color LED array. I picked up some more of them on eBay lately and they had a different pin-out. The MEU 8860 […]
Adding an ADC to the Raspberry Pi app note (PDF!) from FTDIChip: This application note will show how to connect the RPI-Hub-Module to the Raspberry Pi and install FTDI drivers to control the module. The application note will then explain how the module may be used to read values from an external ADC device over the SPI […]
MisterM wrote this instructable detailing his 1981 portable VCR Raspberry PI media centre: This is an early ’80s Sharp VC-2300H portable VCR that I’ve converted – it now has a Raspberry Pi at its heart, running the excellent Raspbmc media centre software. Other upgrades include a snazzy arduino-based clock and an EL wire “tape” that ejects […]
A PCB for Raspberry Pi WH1080 weather station by Andy Ayre of BritishIdeas: Previously I wrote about using a Raspberry Pi to receive 433MHz signals from a WH1080 weather station. This is the mess of wiring I came up with. This worked fine until it stopped. I probably didn’t crimp a wire properly and too many knocks […]
