This is a USB and serial backpack for simple HD44780 character LCD screens. It has a few nice features that set it apart from the serial-only LCD backpacks at SparkFun and Adafruit:
USB and serial control of characters LCDs
Supported in common software (LCD Smartie) as ‘matrix orbital’ display
Adjust contrast and backlight from software
Couple extra pins for buttons

Today we have repaired a LCD Monitor Hanns G HQ191D with model no: HSG1018, came with symptoms that will not to turn on. I opened it and saw that the electrolyte(C907-100uF/400v) cracked, I checked all the primary power supply and I found that the bridge rectifier is in short circuit, and of course (F901-2.5A) fuse protection has been cracked. I changed them and now here it is.

Today we start with a new category called a “Repairing Section”and start with something easy:), changing the inverter board on LCD Monitor AG Neovo E-19A.The problem was that the monitor turns off after 2 seconds. I want to say that the inverter board did not roll CCFL transformer, so I could not find the original CCFL transformer, so I decided to put a new inverter. Inverter I found on ebay and I changed it and now here it is.

Writing a code for an analoge clock may seem a bit of a daunting task. Especially the calculations for the positions of the hands, but it isn’t really that hard at all.
In this instructable I will talk a little bit about the theory and then we’ll move on to the actual code itself. This was just a project build on the breadboard, while building my wifi radio. It started life as the script for a grafical volume button and ended up as a clock that never made it in the final project but it might come in handy for one of you out there.

adafruit.com has lots of 2.8″ TFT breakouts in stock and a brand new tutorial for drawing bitmaps of any size from SD storage!
We have an example sketch in the library showing how to display full color bitmap images stored on an SD card. You’ll need an SD or microSD breakout board such as this one . You’ll also need to download our SD library modifyied to allow faster reads (these changes will be added to arduino v23) but for now you can download the new library here . Download the library by clicking the Downloads button and uncompressing the folder. Replace the files in your ArduinoIDE/libraries/SD folder and restart the IDE.

The Computerless Arduino consists of two major components; an Arduino-compatible microcontroller loaded with a realtime code interpreter, and a stand-alone 5-button LCD display to display port values and manipulate code. The display can be connected to the Arduino via a 4-pin port at any time to peek at In/Out values, view the current code, and make changes as desired.

I recently obtained a very old mobile phone from a friend. The battery was dead, so I dismantled it and to my surprise found a display with soldered contacts. In other mobile phones the display was connected via a conducting polymerpad, which was extremly difficult to use on selfmade circuitboards.

This tutorial shows how to use the advanced functionality of HD44780 16×2 LCD’s where you can create your own characters instead of using the built-in character set. It also gives a simple demonstration of animation on the LCD module.
