Animated Weather LED Display -  21-Mar-14 -Design News:   This project displays the weather in the form of an animation on an LED matrix  (32x32 resolution or 1024 LEDs) .  The Raspberry Pi is periodically pulling weather conditions from the Internet and then sending a corresponding animated gif weather animation to the IOIO board and LED display.  IOIO is an __ Gadget Freak-Case #252

ArroW & Line Running LED's -  Our ARROWERL10 has many applications; fill your party with running blinking ARROWERS.  Mount the ARROWER on your bicycle so you'll be more visible and have a safer ride when signaling.  Mount it on a sign as an direction indication.  Place ARROWER anywhere you’d like to draw attention and a smile.  The unique small design will allow you to mount it almost anywhere.   __ Contact: Kit from Elich Industrial Development, Corp

AT89C2051/4051 Scanning 7 Segment Display & KeypA - D -  Since the output buffer ofP1 can sink 20mA    (each output pin, but maximum IOL for all outputs was limited at 80mA) , thus we can use P1 to drive LED display directly.  As shown in the circuit, Two common-anode 7-segment LEDs are connected to P1 with 180 Ohms current limiting resistor.  Each segment of two LED __ Designed by Wichit Sirichote

Audio Bargraph Display -  An easy to use LED bargraph display to monitor audio levels.  Circuit monitors a single channel, so build two for stereo.   __ Designed by Andy Collison

Audio noise generator drives earphones or small speaker  -  This is a circuit that generates white noise, rolled-off to drive earphones or a small speaker.  White noise creates is a "rushing" sound, which sounds something like air rushing by your ear    (s) .  White noise would be flat with frequency, and since this circuit rolls off within the audio range, I refer to it as "rolled-off" noise.  White    (or rolled-off) noise __ Designed by Dick Cappels
