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! :-)
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.
I went to the DorkbotPDX Open Lab today (Feb 26th, 2012) at ADX and sat down to play with the Kinect I got a while ago. The result is a "Cat Sequencer" that uses the Kinect to trigger samples. There are two looping samples and one non looping sample. The trigger areas for the samples have been placed around the plates. They are visible on the computer as cubes. The more solid the cubes the more filled the trigger area is. Once the trigger is filled enough, it plays a sample. Read on for more details and code.
I recently published a new AltSoftSerial Arduino Library. It's meant as an alternative for Arduino's normal SoftwareSerial library, for more demanding applications that need simultaneous data transfer.
