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.
At Maker Faire, I met Philip Torrone briefly. We talked about driver installation issues, and he resolved to find someone at Microsoft if I would send a summary.
Phil ended up posting on the Make Blog. There've been many reactions, mostly online comments, some in private email.
I'll briefly summarize the responses and offer my opinions here. Just click "read more"...
This is a ARM LPC1343 development board with a nice 132x162 16 bit color TFT LCD display, a microSD card, USB and LiPo recharging. I used it as a name badge at the San Mateo Maker Faire this year.
I've recorded today's solar eclipse with a CdS photocell tapped to my shop window. The voltage divider feeding Teensy's ADC favors dim light so I'm actually surprised to have seen the event. Clouds have got to be pretty dark to show up. The eclipse was darker.
The data shows totality at 6:15 pm. I sample at five minute intervals.
Kudos to Don Park who suggested I take a look at this. I'm wishing I'd tuned the sensor up to get more and better data. When's the next eclipse?
Last week I wrote firmware to control el wires by MIDI.

The IDEA is this:
taking an 8x8 LED Matrix... having it display a letter in a 5x5 section of the display(top left corner lets say) then displaying below it the corresponding Morse-code - . - where 2 leds == a dash, 1 led == a dot, and then a blank led to separate each dash/dot... then hooking up a small speaker to out put the Morse-code audibly...and scroll through the alphabet and digits 0-9 prefer using a Teensy as it would make a nice smallish package :)
Really just need help with how to write the sketch to display the different parts together all at once...
Scott tested and programmed my hand-soldered Bus Pirate at the meetup last Monday. Apparently it works. Not sure when I'll actually use it, but nice to know it'll be ready to go....
Just wanted to post a high quality photo of the Bus Pirate board, Dorkbot PDX version.
Thanks Greg, Scott, Jim, Monty, Jared, and everyone else who had a hand in making this happen! :-)
I delivered some Bus Pirate kits at the last DorkbotPDX meeting and I'm about to ship the kits to those that mail-ordered them. So I figured you might find some instructions helpful.
Thanks to Russel for this awesome battery, and of course Elco Jacobs for writing ShiftMatrixPWM.
