I recently attended a lecture on Optomechanical accelometry for inertial navigation, from NIST (National Institute for Science and Technology in the US). It's very clever, probably an advance in the art. They are at the noise floor for such devices. One fundamental limitation they mentioned was "laser noise" causing a 1/f noise peak at low frequencies. This rang a bell - didn't Phil H...

LPC804: 15 MHz Cortex M0+, 32kB flash, 4k RAM, 12-bit 2 us ADC with 1 LSB DNL, 10-bit DAC, the usual serial stuff, 20-TSSOP: 67 cents in reels, dev board $27. We're using it for a super-quiet diode laser controller where it will run the temperature control and automatic power control loops. I'll never use another ATmega. ;) Cheers Phil Hobbs -- Dr Philip C D Hobbs Principa...
