Ask Hackaday: Why Don’t We Have Flexible Displays Yet?

November 8, 2014 by Mathieu Stephan 90 Comments

A few times a month we receive extremely well crafted crowdfunding campaigns in our tip line that make us doubt our sense of reality. While this article therefore isn’t a hack, we felt it would be a good place to start a discussion around OLED flexible displays.

As the dedicated Wikipedia article states flexible displays have been around for a few years already. In 2013, the Samsung Galaxy Round was unveiled as the world’s first mobile phone with a 5.7″ flexible display. The phone (and the screen) were curved in shape but the phone itself was solid. The same goes for the recent Samsung Gear S smart watch.

Yet for only $350 in a $50k goal crowdfunding campaign the Portal flexible wearable smartphone seems to have all the answers. It is scratch & shatter proof, water-resistant, flexible, includes a ‘Portal proprietary flexible battery’, the ‘Fastest multi-core CPU’, gyro, compass, barometer, Bluetooth 4.0, NFC, GPS…. Specifications are even subject to change to ensure the best available components… and it is 89% funded. As they mention,

building a smartphone or a tech company isn’t rocket science.

We also found a 70% funded €100k crowdfunding campaign for a watch bracelet (right click to translate) that will include GPS, Bluetooth, NFS (not a typo), a uSD card, a 4 lines LED screen and a battery for a few days autonomy… how surprising that no major manufacturer thought of that.

This leads us to the title of this post: why don’t we have truly flexible displays yet? We’ll let our readers discussion this point in the comments section below…

SOAP: The Home Automation Router And Kickstarter Scam

March 7, 2014 by Brian Benchoff 141 Comments

How would you like a 7″ tablet with a Quad-core ARM Cortex A9 processor, USB 3.0, 32 GB of storage, 802.11ac, four ports of Gigabit LAN, Bluetooth 4.0, NFC, SATA, HDMI, built-in Zigbee and RFID modules, a camera, speaker and microphone, all for $170? Sound too good to be true? That’s because it probably is. Meet SOAP, the home automation router with a touchscreen, that’s shaping up to be one of the largest scams Kickstarter has ever seen.

There have been a few threads scattered over the web going over some of the… “inconsistencies” about the SOAP kickstarter, mainly focusing on the possibility of fake Facebook likes and Twitter followers. There’s also the question of their development process: they started building a router with an Arduino, then moved on to a Raspberry Pi, a Beaglebone, Intel Atom-powered Minnowboard, the Gizmo Board, PandaBoard, and Wandboard. If you’re keeping track, that’s at least six completely different architectures used in their development iterations. Anyone who has ever tried to build something – not even build a product, mind you – will realize there’s something off here. This isn’t even considering a reasonably accurate BOM breakdown that puts the total cost of production at $131.

The most damning evidence comes from screenshots of the final board design. These pics have since been removed from the Kickstarter page, but they’re still available on the Google cache. The SOAP team claims they’re putting USB 3.0 ports on their board, but the pics clearly show only four pins on each of the USB ports. USB 3.0 requires nine pins. A closer inspection reveals these screenshots are from the files for Novena, [Bunnie Huang]’s open source laptop.

Scam-o-Matic Determines If You Bought Fake SD Cards

December 7, 2011 by Mike Nathan 37 Comments

[Andrew] recently got scammed on an SD card purchase and put together a small tool that can help you determine if you’ve had the wool pulled over your eyes as well.

You see, he purchased a set of MicroSD cards, all of which had an advertised capacity of 4GiB. When he tried to use them, they all failed to write more than about 115MiB of data, so he knew something was up. He sat down with some tools that can be used to check the actual capacity of flash media, but he says they were unbelievably slow to scan the cards.

While he waited for one of the scans to complete, he decided to create a utility of his own that would do the same thing in a fraction of the time. His quick and dirty application, called “Scam-o-Matic”, writes random data to the card, double-checking the written region to ensure that data can be read back. If it finds errors your card is likely either a fake or damaged, but if not, it automatically prepares the media for use.

Obviously this sort of situation is relatively rare, but if you think that you have picked up some shady SD cards, be sure to check out [Andrew’s] Github repository.
