Direct communication between cell phones using flashlight and camera

Aside from Wi-Fi and Bluetooth near field communication (NFC) cell phones can communicate (theoretically) by sending signals with a camera flashlight and receiving them with a camera. As alternative, the phone's screen can be used as a transmitter.


Here is document (a copy) and video describing similar communication method.

Also there are mysterious Morse Code apps I have to explore: http://www.androidzoom.com/android_applications/morse+code+communication

DECT cordless phones can talk to each without the base station

In discussion http://www.physicsforums.com/showthread.php?t=517690 user xts says:
"You may take a pair of handsets from your home for a picnic and talk in a walkie-talkie mode, even if handsets are out of range of your base station."
Interesting idea. I have to give it a try.

URL probing technique

With all those SEO-friendly URLs it's entertaining to see how the web application respond to misspelling/typos in different parts of the "folder hierarchy". Depending on how close misspelling to a root of the URL the application would throw something ranging from nice "article/product not found" to ugly 500 or 404 canned error page.

And that's how one can sniff what CMS and shopping carts website is made of ;-)

Plug computer, сервер в электрической вилке

Калифорнийская компания Marvell Technology Group выпустила компьютер, по размеру сопоставимый с зарядником для телефона.

Внутри него поместились и блок питания, и центральный процессор с тактовой частотой 1,2 гигагерца (компания особо подчёркивает, что едва ли не единственная сумела втиснуть систему высокой производительности в столь малый корпус), память DDR2 на 512 мегабайт и флеш-память такого же объёма, слоты SDIO, USB 2.0 и мини-USB, а также гигабитный Ethernet и толика сопутствующей "кремниевой мелочи".

User Interface for Seniors

IDEA:
Create GUI explorer application (exe/flash/web) that present computer services (address book, schedule, multimedia, structured data, emails, IM, web, etc...) in very simplified and accessible way (as for seniors and mentally disabled).

PURPOSE:
Take unnecessary details of computer system implementation away from busy or dummy user and let person concentrate on what matters most w/o getting into file system, drivers, settings, and other technical and maintenance details. This way busy person will save time and disabled person will have less stress using computer and network services.

PROBLEM:
Current computer-human interfaces simultaneously pursue two independent goals:
1) Make interface (explorer) visually pleasing and easy to use.
2) Keep interface functional nought for computer administration purposes.
Basically, function-rich UI controls made for tech savvy people who do not need fancy stuff so much. Geeks going to survive with command line anyway.
Fancy UI might be liked by mid-level users, but they do not fully utilize all the functionality offered and sometimes even confused by lot of choices and controls.
And the worst - beginners and seniors are left with no suitable GUI because they do not understand basic information technology concepts and/or physically unable to use controls offered.

SOLUTION:
Develop very simplified shell (explorer) application for personal computers that will expose only services with no technical or maintenance details. UI should be simple, intuitive and accessible like ATM menus.

EXTENSION:
Due loose coupling between UI concepts and underlying hardware such solution can be implemented as SaaS or web application.

TrialPay - Revolutionary payment system

How TrialPay Works for Merchants
How Trial Pay works for Consumer

TrialPay service offers consumers to pay for their goods/services by completing ONE offer from the participating providers. Provider pays affiliate reward to TrialPay for the purchase/subscription. TrialPay pays merchant for the goods/services.

Other words: part of the affiliate reward from participating provider goes to merchant and pays off for goods/services consumer purchases from merchant.

Being simple: You want to buy TV and pair of shoes. You go to online shoe store and pay for the shoes with the purchase of TV from online electronics store. Electronics store pays shoe store affiliate reward that covers your shoes.

Simple? Yes!
Revolutionary? No really. Just think how money laundering works ;-)

Panoramic Adapter for Digital Camera



Создание панорамных фотографий с помощью GigaPan осуществляется следующим образом: обыкновенный цифровой фотоаппарат устанавливается на специально разработанную роботизированную насадку для штатива.

Затем робот-штатив делает от нескольких десятков до сотен снимков предлагаемой местности (на максимальном оптическом приближении) в течение приблизительно 10-30 минут, а приложение GigaPan Stitcher (которое пользователь может установить на своём компьютере) автоматически "сшивает" снимки в один. Как утверждают создатели ПО, "с минимальным содействием со стороны пользователя".

Handhelp Laser Projector

Цифровой видеопроектор размером с кубик сахара:

Так, вместо традиционных газоразрядных ламп авторы проектора применили яркие светодиодные лазеры. Вместо множества микрозеркал, управляющих потоками света, они ухитрились установить всего одно, поворачивающееся по двум осям.





... прибор базируется на лазерных диодных излучателях и микромеханической системе развёртки изображения (на основе микроскопического зеркала, быстро поворачивающегося по двум осям).
Однако теперь инженеры встроили в него ещё и систему компенсации вибрации, на основе акселерометров и электроники, которая вмешивается в управление зеркалом, чтобы создавать стабильное изображение даже при солидных "прыжках" проектора.

Remote Presence for Outsourcing

Following are the technically feasible (for the decade already) concepts and their practical applications:

  • Machinery operation: transportation, lading, garbage collection, patrolling and accident scene surveying.

  • KVM hardware or software avatar: Technical support and systems diagnostics.

  • General hardware interface remoting: networked sharing of expensive automotive diagnostic equipment like Tech2Flash, BDM, CANdi etc., HASP keys and other unique hardware.

  • Mobile videoconferencing avatar: senior care, medical response; translation and mediation services for places of conflict.

ZINK - thermal color printer

RU:ZINK предлагает мобильные принтеры без чернил
Специальная фотобумага размером 2 на 3 дюйма покрыта тремя слоями кристаллов, которые под воздействием температуры и давления создают цветное изображение. Разные цвета получаются в результате различного по длительности и интенсивности воздействия на кристаллы.
EN:How ZINK Works
The key to this process is the patented ZINK paper, an advanced composite material with dye crystals embedded inside and a protective polymer overcoat layer outside. Before printing, the embedded dye crystals are colorless, so ZINK paper looks like regular white photo paper. The ZINK printer uses heat to activate and colorize these dye crystals.
