Moo 1.1 Programmer

This board programs the Moo 1.1 from the SPQR group at the University of Michigan.

From the UMASS Moo site:

“The UMass Moo is a passive Computational RFID that harvests RFID reader energy from the UHF band, communicates with an RFID reader, and processes data from its onboard temperature sensor and accelerometer. Its function can be extended with its general-purpose I/Os, serial buses, and 12-bit ADC/DAC ports. The Moo provides a RFID-scale, fully programmable, batteryless sensing platform. The programs execute on an MSP430 microcontroller. The Moo 1.0 derives from the open source Intel DL WISP 4.1. Why is it called the Moo? It’s the beefiest embedded platform in its class with the most code space and RAM for the least energy. The device also resembles a longhorn steer.”

Graphic Equalizer Display Filter Breakout - MSGEQ7

Audio equalizer for use with graphic displays. This simple board breaks out the MSEQ7 according to the application notes, but is not Arduino specific. Currently this is for through hole parts for ease of soldering, look for the SMD version soon.

Pinout:

• LT - Left analog input, use STR and RST to get each band (0-6) of the audio spectrum
• RT - Right analog input, use STR and RST to get each band (0-6) of the audio spectrum
• STR - Strobe digital output, controls the strobe of the equalizer IC
• RST - Reset digital output, controls the reset of the equalizer IC

Bill Of Materials:

• 33pF PTH Ceramic Capacitor x2
• 0.1uF PTH Ceramic Capacitor x4
• 1000pF PTH Ceramic Capacitor x2
• 200kOhm PTH Resistor x2
• Stereo Audio Jack 3.5mm x1
• MSEQ7 IC x2

A breakout and programmer board for an ARM Cortex-M3 based processor

This Electric Imp-powered device detects motion and reports it to you over the web.

It was originally designed to be stuck to a mailbox door to notify you over WiFi when mail is delivered. It could also be used to monitor doors (including garage or pet doors), valuables that you don’t want moved or cookie jars you want to keep children out of.

The board features an accelerometer, light sensor and Lithium-ion/polymer battery recharging built in. It achieves approximately one month of use between charges per 100mAh of battery capacity, assuming two motion activations per day.

This is a totally valid design but I intend to publish a newer version with Li-ion battery protection for unregulated cells.
