RF Wireless and Device Networking

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.."


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.

Here is a vintage frequency counter that you can build and use it for learning and experiments in your home or office lab. The front end circuits have to be studied. This will help young enthusiasts learn some basics of instrumentation. - delabs Notes

Ramsey CT-90 - Portable Frequency Counter 

The CT-90 is a laboratory quality frequency counter that is capable of use in the lab as well as in the field. Utmost care has been taken in all the design stages to insure that sensitivity and reliabilty were not compromised. The CT-90 has been specifically built for the critical user, as demonstrated by; special  timebase options, nine digit display, three gate times, and a count hold feature.

The CT-90 is ideal for portable usage. Leading zero blanking and the micro power oven (optional) allows 2-4 hours of continuous operation using the internal battery supply.

Operation; Operation of the CT-90 is very simple, simply connect your input signal to the proper input jack (10, 60 mhz or 600 mhz) and select the range and gate time. All switches, except the external time base switch (optional) are mounted on the front panel in easy view of the user. A description of the front panel controls follows.
