All-In-One Twisted-PaIR Video Line Receiver, Cable Equalizer & Display Driver - Twisted pair exhibits a rolloff characteristic that requires equalization to correct for, so this circuit shows a suitable feedback network that accomplishes this. Here again the outstanding common mode rejection of the LT6552 is harnessed to eliminate stray pickup that occurs in long cable runs. __ Linear Technology/Analog Devices App Note, Mar 25th 2010

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

Bandpass filter features adjustable Q & constant maximum gain - 3-Mar-05 EDN-Design Ideas Applications such as audio equalizers require bandpass filters with a constant maximum gain that's independent of the filter's quality factor, Q. However, all of the well-known filter architectures—Sallen-Key, multiple-feedback, state-variable, and Tow-Thomas—suffer from altered maximum gain when Q varies Design by Herminio Martínez, Joan Domingo, Juan Gmiz, and Antoni Grau, Technical University of Catalonia, Barcelona, Spain
Big 7-Segment LED Display Board with SPI Interface - Easy build and use, the general purpose Big LED with SPI serial interfacing. Expandable for multiple digits but still uses only three wires for receiving data from any uC boards. __ Designed by Wichit Sirichote
Big LED Clock - The circuit uses a serial-in-parallel out shift register, 74HC595 for receiving serial data from uController board. See example of U5 in the schematic, SER is for data input, SRCLK is shift clock and RCLK is Latch clock. Each data bit is shifted into the register on rising edge of the shift clock. When all data bits are shifted into the 8-bit register, the rising edge of RCLK will clock the data to be latched at each output bit, i.e. QAQH. __ Designed by Wichit Sirichote
