The eight SDI input stages use the new GENLINX¾II GS9024 Equalizer IC. Input Return Loss of the PCB is optimized by using R-L circuits at each input. Each GS9024 performs high quality signal equalization over a wide range of data rates from as low as 30.... -
The circuit is based on the type EL2020 (or similar) operational amplifier which is marled by large bandwidth. The LL2020 amplifies the video signal applied to the input stage, with a gain adjustment range of ±6 dB. Output transistor Q1, a 2N3866, applies.... -
The modular multiplexers described in this application note, take these, as well as other points, into consideration and provide an optimal solution for the video design engineer. The 16x1 circuits are realised using four Gennum GX434 or GX214, 4x1....

The GY4102A is a bipolar, monolithic SPDT video switch incorporating fast control logic. The analog signal path is characterised by low differential gain, low differential phase and low insertion loss, coupled with a ±0.1 dB bandwidth of typically 100....
-
The GX434 is a high performance low cost monolithic 4x1 video multiplexer incorporating four bipolar switches with a common output, a 2 to 4 address decoder and fast chip select circuitry. The chip select input allows for multi-chip paralleled operation....

A simple rotating display. Just spin and enjoy. While the "Air display" is rotating, it writes the message on the air. Because the "persistence of the vision", you will be able to read the message. The operation is super simple and you don't need an user.... -
Want to add video to your next project? This device uses a PIC16F819 and not much else. Getting 20 characters to a line is possible by using the SPI port to generate video. Neat trick, eh? The character set is limited to upper case and a few punctuation.... -
I recently purchased 10 SLM1608 (SLM1606) LED matrix display units from Ebay (you might also contact the seller directly at [email protected]). These are 16x16 LED matrix units with a green and a red LED per pixel allowing each pixel to be switched to either.... -
You may need also need 10 diodes and different resistors, especially if you are using white LED`s please the Troubleshooting section in step 3 for details. . 005 ³ thick matte drafting film I bought a sheet from a local artist`s supply store. The smallest.... -
Here`s an another project, which makes an Scrolling LED display. Here 64 leds which are connected to an Matrix display. The Anodes are drived through an Driver... -
Multiplexed displays are electronic displays where the entire display is not driven at one time. Instead, sub-units of the display (typically, rows or columns for a dot matrix display or individual characters for a character orientated display, occasionally.... -
Designing a controller PCB for a 10x10 white LED matrix clock (inspired by the tutorial here ). It`s based off an ATmega328 AVR IC and Maxim DS3234 SPI RTC. However, I`m stuck: I have no idea how to control my custom non-standard 10x10 LED matrix. Originally.... -
LEDs provide a convenient way to electronically display information. Although the seven-segment LED display, arranged in the form of the digit 8, is commo.... -
A new spin on a great kit. Have you ever seen the dot-matrix displays that can display letters, numbers, or even icons Once you know the basics for how to display something on one matrix, you can daisy-chain the Maxim Max7219 ICs and LED matrices to display....

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
