Network Speakers

| 1 Comment

I had an unused Mini-ITX computer which I can make silent (by removing the fan) as long as it isn't doing anything too intensive, and some spare speakers from a broken CD player... so I put together some remote speakers to play music on.

With some cheap bamboo cane and tie wraps I've mounted them at the head of my bed. The server boots over the HomePlug network allowing MPD to connect to it. I'll add a wireless remote control soon.

USB powered doorbell

| No Comments

I have a second doorbell because the one in the living room is too far away to hear from the computer - especially with music playing - but it uses up AA batteries far too quickly and I don't easily notice that it's no longer ringing with the main one. So I connected it up to a USB port instead...

NTP reference clocks

I've finally finished putting together the parts to connect multiple NTP reference clocks to the same serial port...

It uses three reference clocks - one GPS receiver and two radio clocks (DCF77 and MSF).
