Last night on the net I spoke a little about the Android operating system. It’s gaining a lot of popularity and is hugely supported, and it’s FREE.

We should consider this for a myriad of reasons, I’ll just mention a few that hit me.

1) It’s designed for communication systems. What do we do? ;]
2) It’s open source and accommodates free software and development quite nicely
3) There is a huge support community for writing ‘apps’ on Android
4) There are a number of hardware accessories that are coming on the market to facilitate talking to homebrew hardware or commercial equipment.

Here is a link to the development platform. Again, it’s free, and there is a huge pile of data to sift through

The ‘Get the SDK’ link is at the bottom.

These little devices should be available soon. Some are now.
There are others, these got my attention

Here are some projects people have done with the IOIO

I think an informed conversation on the Android platform would make for a great net. Read a little about it and perhaps even download and install the SDK. Got the Hello World app running on your phone or tablet? Tell us about it! Failure? Lets try to solve it.

I see a great application of Android and homebrew radio with the proliferation of inexpensive Tablet PC’s coming on the market. Also, there are devices like the Mini6410 and other project type embededed devices that are capable of running Android and have LOTS of IO built onto them. Do a little creative searching and see what other similar hardware you can find and what projects may be out there that interest you.

Keep in mind you can still develop for older versions of Android. Why? Lesser capable hardware for one, as well as devices that are not intended to run a display with all the fancy graphics and touch screens.

Perked a little interest? I hope so. If so, bring yourself to the next Tech Net and lets talk Android for Ham Radio!

Software-defined radio
From Wikipedia, the free encyclopedia

A software-defined radio (SDR) system is a radio communication system which uses software for the modulation and demodulation of radio signals.

Full description is here.

This is what I wrote about them in the past.

Here is upcoming SDR radio being developed: the SDR-908 mobile SDR radio
