A higher channel separation stereo encoder built with 3 iC’s 4066, 4047, 4013 and 741. It has a filter L, C5 for frequencies higher than 15kHz and an extra audio amplifier built with 741. This stereo ...

I wrote up a piece about AustriaMicrosystems’ 12 bit hall-effect rotary encoder and the ebullient and cheerful Mary Bohenek was nice enough to send me a demo board. This thing is a blast—imagine ...

[Rupert] got his V-USB/ATtiny85/rotary encoder circuit working, and at the expense of a ‘mute’ control, also added an awesome looking RGB LED ring powered by Adafruit’s Neopixels.

1. This optimised analogue-conditioning circuit can avoid signal distortion caused by nonlinearities, and guarantee an optimum interface between the encoder and ADC.

RF Solutions has introduced a pair of encoder/decoder ICs for radio-control applications, featuring three independent I/O lines and allowing direct connection of an RF module to simplify design.

Qualcomm has taken a 2.64% stake in Sharp by buying 30m Sharp shares for $60m. The present intention is for Qualcomm to lift its stake to 5.2% via a similar deal in March, though Sharp says this ...
