You can find all kinds of LCD screens in broken electronics. But it’s often a chore to figure out how they are controlled if you don’t have a working device that can be used to sniff the communications protocol. [Justin] grabbed this character LCD screen from an old Brother printer and decided to see if [...]

This Arduino BASIC interpreter will make a really fun one-day project if you’ve already got the parts on hand. [Usmar A. Padow] put together an Arduino Uno, SD card, four line character LCD, and PS/2 keyboard. but he’s also included alternative options to go without an LCD screen by using a computer terminal, or without [...]

[Tom Fleet] spent the dreary weekend inside learning how to drive this T6963C based graphic LCD controller. Although this is his first time venturing away from HD44780 character displays, the availability of an Arduino library helped him go from being a newbie to coding his own animated graphics. The hardware setup is straight-forward. The screen [...]

LCD displays taken from old Nokia phones have been a staple of the hardware makers for years now, so we’re very happy to see [Andy] reverse engineering a full color QVGA display so we can move our grayscale projects over to a full-color display. The screen in a Nokia 2730, 5000, and 7100 cell phone is a [...]

Apparently, there’s some sort of sporting event being televised this weekend that has been historically used as an excuse to buy a big-screen TV. [Joel] wanted a huge-screen TV on the cheap, so he converted an overhead projector to something he can use with his XBox. Using a bare LCD panel with an overhead projector is [...]

Little, no name, 1.5 inch LCD photo key-chains are all over the place for practically nothing. Not too surprisingly these things do not vary much in the parts that they use, some flash ram, a little lipo battery and a 16 bit color LCD. Wanting to find a way to reuse that LCD [Simon] Has [...]

One of the benefits of working in IT is that there is typically a healthy supply of miscellaneous, half-functioning equipment to mess around with. [Vittore] had an old laptop with a busted LCD sitting around (Google Translation), so he figured he might as well get it to do something useful. With a spare desktop LCD [...]

[dimovi] had a spare LCD monitor sitting around and thought it would be great to convert it into a “privacy” monitor. The process is simple enough for anyone comfortable with disassembling electronics. He took apart the monitor’s plastic frame, cutting out the polarized film with a utility knife. Once the film was removed, he spent [...]

[Kaushlesh Chandel] prototyped a few projects on his Arduino that use an HD44780 Character LCD. Wanting to keep these projects in one piece, but not sacrifice his Arduino board, so he etched his own LCD backpack that is Arduino compatible. If you’ve never made it past the Arduino board to build a module that only uses [...]

[El Artis] just finished building an audio spectrum analyzer that uses a character LCD. The uses an Arduino to drive the display, but unlike other meters that use the microcontroller for analysis, [El Artis] is using a discrete IC for that task. This project uses the MSGEQ7 graphic equilizer display filter chip to grab frequency data [...]

Here’s an Android accessory project that adds a secondary LCD display. It utilizes the Android Open Accessory Development Kit standard to connect the 16×2 character LCD as a USB device. It pairs an app on the phone which runs transparently with firmware for the ATmega2560-based Arduino compatible board you see to the left. The app [...]

Hackaday forum member [Emeryth] recently posted his newest creation, the Wifon 2.0, which is an update to a project we featured last year. The second iteration of the device looks to make several improvements on the already solid concept. Ditching the simple 16×4 LCD, version 2 sports a full color 320×240 touch panel LCD. A faster [...]

[Fileark] had the backlight on his digital picture frame go out one day. These are generally Cold Cathode Fluorescent Lamps which require an inverter to source the voltage necessary for proper operation. When they stop working, the inverter is usually to blame. Since that circuit is made up of pretty small surface mount circuitry, he decided to [...]

[Scott] was looking to source some LCD screens for an upcoming project, and was considering buying them from SparkFun. While the Nokia panels they sell are not expensive, they aren’t necessarily the cheapest option either – especially when building in volume. He searched around for something he could use instead, and settled on Blackberry screens. [...]

This hack is a bit older, but one aspect of the setup makes it worth sharing. Shift registers are a common component to include in a project when you need to increase the number of I/O pins available. We’ve used them to drive LCD screens before, but we never realize you could use a 595 [...]

[Devon] recently repaired a handful of Phillips LCD projectors which he was quite excited to use. The only problem is that he didn’t want to mess with replacing the bulbs after every 2000 hours of use at $100 apiece. He was pretty confident that he could find a better way to drive the projectors, so [...]

[Foobarbob] posted a pretty simple job of bringing an LCD viewfinder back to life. He doesn’t specify what was wrong, but since he replaced the backlight, we’re guessing that was the main issue.  It was pulled off of a JVC camcorder. The camcorders with LCD viewfinders are getting more and more common at garage sales, [...]

We’ve seen these little toys called “sugar cubes” by GirlTech around for a while now. They are a toy block, with an LCD on the front and they respond to movement, button presses and they interact with each other if you stack them up. We’re just as curious as anyone else about their internals, but [...]

This swivel arm LCD screen is [Ben Heck's] latest hack. It replaces the hinges that normally only allow one point of rotation on the screen.
