Frequency Counter - Giga Hertz

"Imagine you have a radio receiver and you wish to display the receiving frequency. As you know the oscillator in a radio receiver works 455 kHz or 10.7 MHz above the receiving frequency. The 455 kHz and 10.7 MHz difference is called IF (Intermediate Frequency)."

2.5 GHz Frequency counter

A Google talk around 2006 with another electronic enthusiast

davidhvm (3:36:51 PM): Hello, i assembled de prototype and work fine
davidhvm (3:37:24 PM): anyway i add a push button to Set/Reset to 00 the counter
davidhvm (3:37:39 PM): thanks a lot again
davidhvm (3:38:13 PM): check this 2.5 GHz Frequency counter
davidhvm (3:39:07 PM): i'm looking for some apps for counters and i
found a lot o pages with very usefull
davidhvm (3:39:44 PM): circuits of course with PICs (Microchip or Atmel)
davidhvm (3:39:47 PM): Bye
delabs (3:44:58 PM): hello david
davidhvm (3:45:37 PM): hi all work fine
delabs (3:45:48 PM): great
davidhvm (3:46:40 PM): are amazing these projects
davidhvm (3:47:15 PM): ok thanks may be for long time
delabs (3:47:30 PM): fine
davidhvm (3:47:41 PM): i'm at middle of my carrer

Tizen was MeeGo who was Moblin or Mobile Linux

Moblin hosts the Mobile & Internet Linux Project which is an umbrella, open source project focused on the development of Linux for Intel-based devices.

"To this purpose, moblin will host various projects that will provide key elements of community-based projects such as Ubuntu Mobile and Embedded Edition, Red Flag Midinux, and Pepper Linux.."

 Tizen was MeeGo who was Moblin or Mobile Linux
MeeGo was designed to act as an operating system for hardware platforms such as netbooks, entry-level desktops, nettops, tablet computers, mobile computing and communications devices, in-vehicle infotainment devices, SmartTV / ConnectedTV, IPTV-boxes, smart phones, and other embedded systems.

Smartwatchs started with Android, now they have a Tizen version, this watch may be a good experimental hardware for Embedded Systems hackers to test out their own custom linux firmware !

If you haven't heard, in 2010 Moblin became MeeGo! MeeGo is an open source, Linux project which
brings together the Moblin project a single open source activity.

By now, you may have read that The Linux Foundation, with the support of several other companies, announced a new project, Tizen, to build a new operating system for devices. This new project is first and foremost open source, and based on Linux. So it begs the question: why not just evolve MeeGo? We believe the future belongs to HTML5-based applications,

Tizen - An open source, standards-based software platform for multiple device categories.

For Smartphones, Tablets, Netbooks and Smart TV. Also one for your Car, Boat or Chopper for an In-Vehicle Infotainment Gadget.
