 New "World's fastest compact microcomputer" The Teensy 4.0   $19.95              ARM Cortex-M7 processor at 600 MHz, contained in NXP iMXRT1062 chip Executes 2 instructions at a time (about 40% to 50% of the time compiled by TeesyDuino),   Employing tightly coupled split memory with 2 64 bit paths.. FPU handles Double Integers as well as Floats 1024K RAM (512K is tightly coupled)  2048K Flash (64K reserved for recovery & EEPROM emulation)  Lots of interfaces  6.6 X faster than ESP32 in one benchmark. (331 X faster than Arduino AVR Mega)  The Teensy board line appears to be the product of a one man operation run by Paul Stoffregen, he seems quite competent and is active on the support forum, his store is a little behind, it took some hinting to find the sales page for the Teensy 4.0.  It works with Arduino IDE his variation called TeesyDuino, using an installer t...

ongoing topic... Hand Gesture Input with Tactile Feedback There are circumstances and users that require unconventional input devices, some examples:   Leapmotion ,  the hand gesture input device maker and Ultrahaptics , the leading supplier of ultrasonic Haptic (tactile feedback) device have joined forces to form ultraleap.com a promotion site site for the combining of these 2 separate products to provide an enhanced user experience.    The Ultrasonic emitter array used in Haptic interfaces is similar to the Sound Flashlight recently demonstrated.  Some demonstrations allow a user to "feel" simple geometric shapes.    Leapmotion uses Stereo cameras and IR lights to identify hand gestures, it's a processing intensive and limited approach compared to scattered laser emitter 3D imaging using in Kinnect games and iPhone Face recognition, I lost some enthusiasm about Leapmotion when they retooled their software for use with VR headsets inste...
