People always tell us that their favorite part about using a computer is mashing out the exact same key sequences over and over, day in, day out. Then, there are people like [Benni] who would rather make a microcontroller do the repetitive work at the touch of a stylish USB peripheral. Those people who enjoy the extra typing also seem to love adding new proprietary software to their computer all the time, but they are out of luck again because this dial acts as a keyboard and mouse so they can’t even install that bloated software when they work at a friend’s computer. Sorry folks, some of you are out of luck.
Rotary encoders as computer inputs are not new and commercial versions have been around for years, but they are niche enough to be awfully expensive to an end-user. The short BOM and immense versatility will make some people reconsider adding one to their own workstations. In the video below, screen images are rotated to get the right angle before drawing a line just like someone would do with a piece of paper. Another demonstration reminds of us XKCD by cycling through the undo and redo functions which gives you a reversible timeline of your work.
If you like your off-hand macro enabler to have more twists and buttons, we have you covered, or maybe you only want them some of the time.

The Microsoft Surface Pro 3 is a neat little tablet, and with an i7 processor, a decent-resolution display, and running a full Windows 8.1 Pro, it’s the closest you’re going to get to a desktop in tablet format. Upgrading the Surface Pro 3, on the other hand, is nigh impossible. iFixit destroyed the display in their teardown, as did CNET. [Jorge] wanted to upgrade his Surface Pro 3 with a 1 TB SSD, and where there’s a will there’s a way. In this case, a very precise application of advanced Dremel technology.
Taking a Surface Pro 3 apart the traditional way with heat guns, spudgers, and a vast array of screwdrivers obviously wasn’t going to work. Instead, [Jorge] thought laterally; the mSSD is tucked away behind some plastic that is normally hidden by the small kickstand integrated into the Surface. If [Jorge] could cut a hole in the case to reveal the mSSD, the resulting patch hole would be completely invisible most of the time. And so enters the Dremel.
By taking some teardown pictures of the Surface Pro 3, printing them out to scale, and aligning them to the device he had in his hand, [Jorge] had a very, very good idea of where to make the incision. A Dremel with a carbide bit was brought out to cut into the metal, and after a few nerve-wracking minutes the SSD was exposed.
The only remaining task was to clone the old drive onto the new one, stuff it back in the Surface, and patch everything up. [Jorge] is using some cardboard and foam, but a sticker would do just as well. Remember, this mod is only visible when the Surface kickstand is deployed, so it doesn’t have to look spectacular.
Thanks [fridgefire] and [Neolker] for sending this in.
[HyPe] over at the Natural User Interface Group developed this concept as part of his Master’s Degree in Industrial Design. This suitcase sized projector and computer allows people to have a 60″ multitouch screen available wherever there is a large enough surface. The current software is designed for ad-hoc meetings about large-scale construction plans. The rolling case includes a short-throw projector and webcam. Just set it on top of your work surface, lift the lid, and it’s ready to go.
[Johnny Lee]’s colleague [Paul Dietz] has done some interesting work using interactive tables. He’s specifically researched how to determine how full a drink glass is. In the video above, he’s using Microsoft’s Surface, but this technique should work with any IR camera based multitouch table. Determining the drink level requires custom glassware that has a small prism inside. When the liquid level is above the prism, light passes through, but when it’s below the top it reflects more IR light back into the table. Using this information, restaurant staff could serve drinks in a more efficient manner.
[Paul] has worked on another project that uses RFID and capacitive sensing to a similar effect.
If you’ve got an extra grand laying around, you can pre-order one of [nortd]’s touchkits. It features a unique custom made acrylic screen with a crap ton of IR LEDs embedded in it. An included IR camera provides the input and a projector (you get to supply your own) is used to light the surface. We mentioned this in our multitouch roundup and you can find a video of it embedded after the break.

Time was, coffee tables were good for three things only: setting down your coffee, setting down your coffee table books, and maybe putting your feet up. To combat this perception, Born Rich has posted their top ten list of high tech coffee tables that are capable of these things and more.

[Christopher Jette] did a amazing job converting a 56″ rear projection television into a multitouch display. His original inspiration came from this drafting table project. The screen is a large sheet of 1/2″ acrylic with a screen material attached to the back side. The screen edge is surrounded by 168 IR LEDs. When a finger tip touches the surface it scatters the LEDs’ IR light. A webcam sees this scattered light and determines where the fingers are. Inside the box is a standard video projector. This is a great reuse of old equipment and we love to see a hobbyist making up ground where manufacturers aren’t. For more info on multitouch projects, we suggest the Natural User Interface Group. Here’s a video of [Christopher]’s display in action:
