Here’s an interesting take on a Lego clock, it uses rotating squares to change the orientation of the black and white tiles to display the needed number. As we see one of the digits cycling to the next number in the video after the break, a couple of different things pop into mind. This seems very much like a 1-dimensional Rubik’s Cube, and it also has a hint of a very large ePaper display. Those use magnetic fields to swivel microspheres that are black on one side and white on the other.
The timepiece, which was built by [Hans Andersson], is limited to displaying numbers only. If you think about it, each row is three pixels but you don’t need to have every combination of those pixels available in order to display the digits. Four sides provide enough room for the necessary combinations. This would not be true if you were trying to scale it up to include all alpha-numeric characters.
The tick of this thing certainly sounds interesting, huh?

We love to see Doom ported to new hardware because it usually means that someone has found a way around the manufacturer’s security measures. But the most exciting thing for us to see this time is that Doom II is played on an epaper display. These are notorious for slow refresh rates, but as you can see in the video after the break, this one achieves an admirably fast page redraw.
According to a translation of the original forum post, the PocketBook 360° Plus boasts a 5″ E Ink Pearl screen, 533 MHz Freescale i.MX35 ARM11 processor, 128 Mb of RAM, 2 gigs of storage, and WiFi. No word on price for one of these babies as it seems they’ve not yet been release. Remind anyone of the green monochrome goodness from the original Game Boy?

ePaper displays are easy on the eyes because there’s no flickering backlight to put strain on them. This is great until you’re trying to read in a dim environment. Of course Amazon will sell you a backlight that’s powered from the reader itself if you’re willing to pay. [Txoof] thought the price was a bit too high so he built his own version.
There are two pockets in the top of the Kindle reader for hooks to grab onto. Each has an electrical contact in it and together they provide about 4V of power. To patch into that source [Txoof] cut his own hooks from brass stock and mounted them onto a piece of basswood. He then cut and bent a hood from more of the brass stock to house the LEDs. A series of three of the white diodes draw their power from the hooks and shine onto to the display. As you can see this works just fine, but could benefit from just the right diffuser.
If you’ve never heard about electronic paper, crawl out from under that rock and read up on the Sony Reader and the Amazon Kindle. E-paper is a flexible display made of color-changing beads that mimic ink-on-paper for easy daylight reading. The revolutionary thing about e-paper is that after it’s set, it stays that way without additional power.
This sounds great in theory, but Esquire’s cover is the first time everybody can afford to hack an e-paper display. We took the cover into the Hack a Day lab to document, test, and hack. In the end, we recycled it into something useful that anyone can build. We’ve got all the details on how the display works and what it takes to use it in your own projects. Read about our e-paper clock hack below. Continue reading “How-to: Make an e-paper clock from Esquire magazine”
In celebration of there 75th year, Esquire magazine’s October issue will feature an e-paper cover. The display will be about 3mm thick flexible paper with four shades of gray and some animated text and images. The backside will also have a display featuring a Ford ad for the new Flex. The Ford ad is essentially subsidizing this whole production. The cover isn’t finalized yet, but Boing Boing Gadgets was able to get a few more details about it from deputy editor [Peter Griffin]. The battery isn’t anything exotic and they fully expect people to break the device open and do what they want with it. It will unfortunately still require you building your own controller, but at least you get two revolutionary displays to play with for the cost of a magazine. If you’re wondering what Esquire is, they apparently showed George Clooney 2 Girls 1 Cup. So they’ve got that to celebrate too.
