eBay isn’t only about counterfeit designer handbags and boxes of all-marshmallow Lucky Charms, sometimes there’s actually something useful for sale. [Matt] found a bunch of Chinese-made ARM development boards with integrated LCD displays on the ‘bay, but without a reliable toolchain, these boards – as cool as they are – are nearly useless. Thankfully, he figured [...]

Here’s an external display meant to help you keep track of your computer’s status. It connects via USB and is driven by a PIC microcontroller. It listens for a small set of commands, using those to implement a simple control protocol to drive the screen. [Andrew Gehringer] designed the device around a PIC 18F2550, which offers [...]

[Jasper] sent in a project he, [Quinten], and [Mr. Stock] have been working on for a while. It’s called the Pristitrope and brings the classic 19th centrury paper-based animation device into the 21st century with 18 LCD displays. The lazy suzan portion of the build was fabricated out of plywood cut on a CNC router and [...]

[H. Smeitink] got his hands on a 320×240 color TFT LCD screen. He set out to drive it with a small PIC microcontroller but didn’t find a lot of help out there to get up and running quickly. This is surprising since it’s a really nice display for quite a low price (under $16 delivered [...]

[Tech2077] is one of the lucky ones who already got his hands on a Raspberry Pi. He’s been looking into different interface options with the GPIO header and just posted a guide to using an HD44780 character display with the RPi. We like this approach because instead of doing some hard-core LCD work he’s using [...]

One of [Sprite_tm]‘s colleagues recently challenged him to connect a small LCD touch screen to a Raspberry Pi. Sadly, [Sprite_tm] has yet to take delivery of a Raspberry Pi, but he did manage to connect an LCD to a Linux board without video capabilities. Because [Sprite_tm]‘s display has a 16-bit parallel interface, and 16 GPIO pins are [...]

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.

[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 [...]

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.

[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. [...]
