I’ve always felt the need to have a small screen on my computer to show some “extra” information which I don’t usually want on my screen all the time. By extra information I mean – news headlines, RSS feeds from my favorite blogs, weather updates, CPU usage information, new e-mail notifications, etc. So, to fulfill this humble need of mine, I bought a small (16×2 character) LCD screen for Rs.90 (approximately USD $2). Very inexpensive!:

Nokia manufactures a wide variety of cell phones and many of their cheaper phones contain simple LCD’s which may be used in microcontroller projects. There is one particular LCD model that is used in a wide variety of their phones and is often referred to as simply a “Nokia LCD”, or “Nokia 6100 LCD”. I used to use a Nokia 2600 phone and whenever I upgraded I took the Nokia apart to remove its LCD. This LCD appears to be the same one that is sold as “Nokia 6100 LCD” and I was able to get it up and running with a bit of work using an AVR.

1.8″ TFT Display tutorial! This tutorial is for our 1.8″ diagonal TFT display & microSD breakout board. This breakout is the best way to add a small, colorful and bright display to any project. Since the display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory and few pins available!

This article goes through how to create a VGA controller that uses a resistor DAC to create 512 unique VGA colors. The tutorial uses an Altera CPLD and VHDL code to create all the video signals. The theory, hardware schematics and software are all explained and available for viewing/download.

Poor Man’s LCD Touchscreen Breakout Board… Patrick writes – [via]
If (like me) you like to move around when you code (couch/coffeeshop/bed/etc), then you’ll want to build a breakout board for your setup. I soldered the level shifter IC (4050, required for 5V microcontrollers) and some stackable headers to a perfboard, then screwed the screen & perfboard onto a project box’s lid. I also added two screws to hold a full-sized arduino board in place, when it’s hooked up.

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.
