New project close enough finished to share... thanks to Paul (teensy) and Lean for the help getting this on its way to being done! cheers,
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"...
Dorkbot PDX would like to welcome you to the latest installment of our semi-regular presentation series:
What's happening? Two great and inspiring talks!
The LAMOSO (LAsar/MOtion/SOund) is a MIDI controller; that is, it's a device that sends MIDI to my computer. MIDI is a standard music protocol that allows electronic musical instruments (e.g., the LAMOSO) and computers to communicate with each other. It's not audio - it's digital data that includes values for pitch, length, volume, etc.
So... the LAMOSO uses lasers and photogates to send signals to a computer, which then turns that data into sound.
The lasers hit (or don't hit) photogates. The photogates connect to a Teensy++, a "microcontroller development system" (it's the computer chip thingy in the pictures), and that sends my computer data about whether there is or is not a laser beam light hitting the photogate. Max, a music programming language, is used to interpret that data into music.
Visually and musically, what this means is that there's lasers crisscrossing an area, and when those lasers are broken, it changes the music.
Jeremy Rotsztain writes software to generate digital images that closely resemble
paintings. Instead of working with paints and pigments, he prefers to use digital materials. He collects popular images from the Internet and iconic scenes from Hollywood films -- and uses their pixels and sounds to generate entirely new
Jeremy will be presenting and discussing two recent works:
1) "Obsessions" (prints made from photos of adorable pets)
2) "Action Painting" (abstract expressionist animations made from high octane car chases, violent punches, fiery gun shots, and sublime explosions).
An open-mic session for those looking to show off a project, ask a question, solicit help, or incite collaboration.
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.
"Read more" for details....
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! :-)
