Not too long ago, I bought a small, inexpensive amplifier kit from tindie.

JTAG Nostalgia

JTAG adapter

Long story short: the GuruPlug JTAG wouldn't even debug the GuruPlug, let alone any other board I tried it with. I knew my freshly-compiled bleeding-edge OpenOCD was at least somewhat functional, because it was able to talk to my TI Evalbot through an onboard FTDI2232 USB-JTAG/UART chip. But it wouldn't talk to the FTDI2232 in the GuruPlug JTAG dongle.

ARM LCD Dev Board Eagle files

Recently I posted about the ARM based LCD development board I showed at a Monday DorkbotPDX meeting. At that time, I was waiting for another revision of the board before releasing the Eagle files. I got the next version back and it looks OK so I've attached the files.
The firmware source code is available on GitHub.

Two Years of Pretty Good Service

I engaged Pingdom to monitor my home sensor network several years ago when I started to depend on it and found it undependable. The recent upgrades at Pingdom had me looking through downtime stats wherein I found my service to myself to be pretty good:

The persistent downtimes of 2010 were replaced by occasional outages when I converted from Arduino with an Ethernet Shield to Teensy running Txtzyme from an old laptop. Recent failures are all attributed to power failures outlasting my aging laptop battery or Comcast changing my IP address. I'm especially pleased that my foam core and spring clip infrastructure has been serving me well.
