Steve Gibson has been talking about his "Portable Sound Blaster" (a device that sends high frequency, high decibel sound waves in a focused beam): https://docs.google.com/document/pub?id=1mfc5ZcuqU03ll2qyHl8URd1MvAYzr5swq2_SoCYmpIc
on his "Security Now" podcast and mentioned the microcontroller he plans to use: http://www.lpctools.com/lpc1768.lpcxpresso.aspx It's a $30 "stick"-style single board computer with a 120 MHz ARM Cortex-M3 core: 512 KB Flash, 64 KB RAM, 100 Mbps Ethernet, multiple USB ports, serial, timers, watchdog, PWM, ADC/DAC, runs FreeRTOS, and has free development tools (Eclipse plugin, etc.). Sounds like a lot for $30. I wonder what sort of software-based video compression it could pull off? (Supposedly it has some DSP capability too.) Pair this up with a USB camera to make a highly stable IP camera with firmware focused on streaming video, instead of all the other silly things consumer-grade IP cameras try and do. -Tom _______________________________________________ Hardwarehacking mailing list [email protected] http://lists.blu.org/mailman/listinfo/hardwarehacking
