  • Simple Radio Clock for PC's
    Keep accurate time on a Linux machine based on radio time signals such as DCF77, MSF or WWVB. Found via https://packages.debian.org/stable/net/radioclk
    It uses the modem control input signals to monitor the signal from the radio receiver. For a Raspberry pi, where I want to use this, the articles
    "Raspberry Pi RTS / CTS Flow Control" https://ethertubes.com/raspberry-pi-rts-cts-flow-control/ and
    "Raspberry Pi 3 Hardware Flow Control"  http://www.deater.net/weave/vmwprod/hardware/pi-rts/ will be useful.

  • The Pins They Are A-Changin’
    Some fairly major (and frankly rather overdue) changes are coming in the way that users access the GPIO pins on the Raspberry Pi. The shift will (hopefully) be fairly gradual and, for users of certain libraries, entirely invisible. However, for others they may be quite disruptive. As forewarned is forearmed, hopefully this little article may be of some use to those affected!
