Wacom, purveyors of fine pen tablets for digital artists, basically have two product lines of pen tablets. The first, Intuos, is a great pen tablet that give an artist the ability to turn a computer into a virtual dead tree notebook. The second product line, the Cintiq, takes the same technology and adds an LCD to the mix, effectively turning a drawing tablet into a second display. [Bumhee] wanted a Cintiq, but didn’t want to pay the Cintiq price, leading him to install a display in his old Intuos tablet. It’s an amazingly simple build, making us think we’ll be seeing a few derivatives of his work in the future.
The display [Bumhee] used for this modification is a Retina display from an iPad. With the right adapter, you can easily connect one of these displays to a computer, giving you a very thin 2048×1536 9.7″ display. The initial tests to see if this mod would work on his tablet – removing the metal shield on the display, placing it on the tablet, and drawing – were a success, giving [Bumhee] the confidence to irreparably modify his tablet.
From there, the modification was a simple matter of cutting up the enclosure of the tablet, installing the display with a few screws, and installing a piece of glass over the display. Very easy, and it’s just about the only way you’re going to get a pen tablet with a small, high-resolution display for less than a thousand dollars.
Thanks [David] for sending this one in.
Those fancy 2048×1536 pixel resolution displays found in the iPad 3 and 4 can be used for much more than high def Candy Crush and Netflix viewing. [Freddie] over in Southampton, UK built his own adapter to connect these high-resolution LCD panels to anything with a DisplayPort connection. It’s called OSCAR, and it’s the open source way to add a whole lot of pixels in a second (or third, or fourth….) monitor.
The LCD panels found in the iPad 3 and 4 don’t use the usual LVDS connection found in just about every other LCD panel ever made. It uses an extension of the DisplayPort protocol, meaning any graphics card with one of these ports already does the heavy lifting for this panel. The only other thing that’s needed is an adapter to control the power and backlight, which is easily handled by an ATMega32U4. This makes OSCAR Arduino compatible, making it easy to add sensors and USB playthings.
OSCAR is available on Kickstarter for £65 (~$100 USD) for the board itself. Adding to that, you’ll need to grab an iPad retina display through the usual channels for about $65. Not exactly cheap, but try finding another better-than-1080p display for that price.
If you’ve seen one of the fancy, expensive MacBook Pro laptops with a Retina display, you’ll know how awesome having that much resolution actually is. This incredible resolution comes with a price, though: the MBP with a Retina display is about $500 more expensive than the normal resolution MPB model, and it’s very difficult to find a laptop of comparable resolution without cries of fanboyism being heard.
[Daniel] over at Rozsnyo came up with a neat solution that connects one of these fancy 15-inch Retina displays to just about any computer. The build is the beginning of a product that works just like the previous DisplayPort adapter for the iPad retina display, but with the possibility of a few added features such as HDMI input and use of the internal webcam and WiFi antennas.
This build isn’t really a finished product anyone can buy and plug into a replacement Retina display just yet. Even if it were, it’s extraordinarily difficult to find a replacement display for the high-end MacBook for under the price of a really good monitor, anyway. In a few years, though, when the old, busted Retina laptops are traded up for a new, shiny model, though, we’ll be the first to try out this mod and get some serious desktop space.
You don’t have to search very long before you find someone raving about the Retina display used in Apple iPads. We’re not going to disagree. These 9.7″ panels pack in a whopping 2048×1536 resolution and the color is fantastic. But we were surprised to hear you can get one of these for a meager $55. That’s how [Andrzej] sourced the part when he set out to connect a Retina display to a regular PC.
It turns out this isn’t all that hard. The display uses the eDisplayPort protocol. This is an extension of DisplayPort which is an alternative to LVDS that is gaining a foothold in the industry. An external DisplayPort adapter can already be found on higher-end laptops, which means this should be a snap to use as an external display if the signals can be routed correctly.
To do this, [Andrzej] figured out how to order the PCB connector for the panel’s ribbon cable. He then etched and populated his own board which serves as an adapter for a DisplayPort cable. It even powers the panel, but an external 20V supply is necessary for the backlight.
