Customized iPad LCD Screen Clips onto Macbook as a Slick Second Screen

Macbook with iPad second screen

Last year, [Ben] found a good deal on iPad 3 LCD screens. He couldn’t resist buying a couple to play around with. It didn’t take him long to figure out that it’s actually quite simple to use these LCD screens with any computer. This is because the LCD panels have built-in Apple Display port interfaces. This means that you can add your own Display Port connector to the end of the LCD’s ribbon connector and just plug it into a computer. You’ll also need to hook up a back light driver, which [Ben] was able to find pre-made for around $35.

The hack doesn’t stop there, though. [Ben] wanted to have a nice, finished product. He laser cut an acrylic bezel for the LCD screen that was a perfect fit. He then milled out a space for the LCD to fit into. The acrylic was thick enough to accommodate the screen and all of the cables. To cover up the back, [Ben] chose to use the side panel of a PowerMac G5 computer case. He chose this mainly for aesthetics. He just couldn’t resist the nice brushed aluminum look with the giant Apple logo. It would be a perfect match to his Macbook.

Once the LCD panel was looking nice, [Ben] still needed a way to securely fasten it in the right place. He knew he’d want it next to his Macbook, so why not attach it directly to the Macbook? [Ben] got to work with his 3D printer and printed up some small plastic clips. The clips are glued to the iPad screen’s acrylic bezel and can be easily clipped on and off of the Macbook screen in seconds. This way his laptop is still portable, but he has the extra screen real estate when he needs it. [Ben] also printed up a plastic clip that turns the iPad’s USB power connector and the Display Port connector into one single connector. While this is obviously not required, it does effectively turn two separate plugs into one and makes the whole project that much more slick.

More Counterfeit Apple Chargers Than You Can Shake An iPod At

Phones, MP3 players, designer bags, artwork, money…. anything with value will bring out the counterfeiters looking to make a quick buck. Sometimes the product being counterfeited isn’t even necessarily expensive. For example, an Apple iPad Charger. [Ken Shirriff] got a hold of a counterfeit iPad Charger, took it apart, and did some testing.

So why would someone buy a counterfeit product? To save some money! The counterfeits are usually cheaper to reel the potential buyer in thinking they are getting a deal. In this case, the Apple product costs $19 and the knock-off is $3, that’s a huge difference.

Magsafe On An Android, Cats And Dogs Living Together


We’re thinking most Hackaday readers have at one time or another been tasked with replacing the power connector in a laptop. Anyone who has done so can easily see the genius behind the Apple Magsafe connector. Since the second gen iPhone, there have been rumors Apple will release a cellphone with the Magsafe connector, a great idea, seeing as how cell phones are thrown around even more than laptops. [Tony] got tired of waiting, and had an Android device anyway, so he decided to retrofit a Magsafe power adapter to his Note II.

In the interest of excess, [Tony] is using the absurdly large ZeroLemon 9300mAh battery and case for his device, giving him a lot of room for this hardware mod. A tiny 3D printed adapter fits around a slightly modified Magsafe connector, and with a little bit of super glue and solder, the connector is wired up to the charging port.

Of course the charger isn’t a stock Apple power supply; it’s just another Magsafe plug wired into a 5V wall wart. We’re not going to take a guess at what would happen if [Tony] plugged a stock Apple charger into his modded phone, but the mod works perfectly without the danger of ripping a USB port out of his phone.

VCF East Wrapup MegaPost


VCF East, the fabulous retrocomputing festival held in Wall, NJ this last weekend was a blast. We had a great time, dropped t-shirts and stickers to just about anyone who wanted one, took a lot of pictures, and shot a lot of video. Now that it’s over it’s time for the post-mortem, with one insanely long post.

We saw some very cool stuff that merited its own post, and much more that we simply didn’t have time to video. The previous posts from VCF East:

There’s still tons more, including a tour of the retrocomputer museum that hosted VCF East. The biggest talk was from [Dave Haynie], lord of the Amiga giving part three of a multi-year talk on the soap opera that was Commodore International.

Hackaday Links: February 2, 2014


[Michel] was in need of a 9V battery connector, and in a brilliant bit of insight realized 9V batteries will plug directly into other 9V batteries (just… don’t do that. ever.) Taking a dead 9V, he tore it open, was disappointed by the lack of AAAA cells, and soldered some wires onto the connector.

Sometimes a project starts off as a reasonable endeavour, but quickly becomes something much more awesome. [Wallyman] started off building a hammock stand and ended up making a giant slingshot. We’re not one to argue with something that just became a million times more fun.

We’ve seen solder stencils made out of laser-cut metal, photoetched metal, plastic cut on a vinyl cutter, laser-cut plastic, and now finally one made on a 3D printer. It’s a pretty simple process – get the tCream layer into a .DXF file, then subtract it from a plastic plate in OpenSCAD.

Apple loves their proprietary screws, and when [Jim] tried to open his Macbook Air with the pentalobe screwdriver that came with an iPhone repair kit, he found it was too large. No problem, then: just grind it down. Now if only someone could tell us why a laptop uses smaller screws than a phone…

[Victor] has been playing around with an RTLSDR USB TV tuner dongle for a few months now. It’s a great tool, but the USB thumb drive form factor wasn’t sitting well with him. To fix that, he stuck everything into a classy painted Hammond 1590A enclosure. It looks much cooler, and now [Victor] can waterproof his toy and add a ferrite to clean things up.

Apple And Raspberry Pis


Deep in the bowels of the Internet there are some crazy people who have a wish list for what the next Apple II should look like. The capabilities of this dream machine of 80s retrocomputing is generally said to be something with a 32-bit CPU, a UNIX OS, modern graphics, and networking. This sounds a lot like a Raspberry Pi, so [Dave] built an Apple II to Raspberry Pi adapter card.

Having a Pi talk to an Apple II over a serial connection doesn’t really give either machine the full capabilities of the other. To fix this issue, [Dave] wrote two pieces of software. The first is a UNIX daemon that listens to the Apple II on a serial port connection, handling the Apple II keyboard connection. The second piece of software is a ProDOS disk image file running on the Apple II. With these two pieces of software, [Dave] can run the Apple on the Raspi, or run the Raspi on the Apple, sending files and data back and forth with no problem.

Aside from providing a strange and awesome Apple II to UNIX interface, the Apple II Pi also has a lot of advantages that might not be readily apparent. An Apple II compact flash adapter can be used as an internal hard drive for these pieces of classic apple hardware, and the Uthernet Ethernet card for the AII brings networking. Both of these devices are absurdly expensive compared to the component cost of the Apple II Pi, and what they bring to the table can be easily copied by the Apple II Pi.

The Apple II Pi is just a simple double-sided board with a few resistors, a cap, header, a 7404 inverter, and a communications chip that’s $5 for quantity one. If you already have a Raspi hanging around your workbench and want to soup up an Apple II with some crazy hardware capabilities, you really can’t do better than getting one of these Apple II Pi boards. Now if we could only find the board files…

Video of the Apple II Pi below, showing off all the awesome capabilities of a Pi-powered Apple. Thanks [Itay] for sending this one in.

Examining Vintage Printer Server Hardward for Apple II


Need to share a printer between several Apple II computers? Of course you don’t, but back in the day this would have been a really awesome piece of hardware to own. It’s a Pacemark iiEasy Print (we’re not sure on the capitalization of the name so talk amongst yourselves). It is an automatic buffer and switch that you can have now-a-days for just a couple of Hamiltons. [David] doesn’t mention where he “acquired” his specimen, but all the details about his adventures reverse engineering the card are shared in detail.

First off, we have to mention his unorthodox bench tools. To the untrained eye it would appear that he has attached the iiEasy Print to a Commodore 64; and that eye would be right. [David] says he uses the C64 something like an Arduino (if that’s even possible). The green card is plugged into the C64 memory bus, connecting to the DIP socket breakout board on the left and the chip select pins for most of the other IC’s on the original board. The gist of this setup is that it’s simple to use the “passthrough” DIP socket to monitor what the 6502-like processor is doing, while mapping the memory with the help of the chip select signals.

What did he learn from all this? Quite a lot but you might as well click that link above and hear it from his own mouth.
