Funcube Dongle Software Defined Radio

This is seriously one of the most interesting PC-enabled communication radios I have ever, ever seen.

I have a VHF, CB, Shortwave and AM-FM that are all power hungry amp eaters in the shelter. What if you could replace all those radios with a single USB dongle? Imagine the possibilities! What about a software controlled USB Dongle?!?!? Buy two and keep one as a backup!!!

I am going to get one of these, hell I may integrate a special purpose daemon for one of these into Vault-OS if it has an API.

Brief Demo Here On Youtube

Hey Tex,

Have a look at Weeder Technologies RS-232/usb data acquistion and control hardware cards and drag-and-place GUI interface software (Windows). The software is on site. 32 cards per serial line connected in series. I'm fiddling with the software now to get a feel for it. What would stand out as the big pluses and minuses of VaultOS vs something like Weedtech? (I'm too busy to become too technically skilled.)

If ya get one Tex, don't forget to download the software from to run it. I use this for NetSDR radio on VLF to HF frequencies and it is great. 2 megs of bandwidth at a time.

I love it. It's times like this I feel like there's the potential for a second Golden Age of computing.

Notice Bill O'Reilly uses the word anti-White, 3 times and how Geraldo Rivera starts blinking rapidly, when he first hears it.

Interesting object near the sun.

And did you see this sphere?

The design philosphy of Vault-OS is that there should be nothing particularly special about the hardware. It should not be proprietary or in any way difficult to reproduce.

This entails :

x86 hardware, from old laptops, PCs, dedicated devices, etc.

LPT Relay Boards for controlling switching (built from auto relays in cars where needed)

Simple serial line connections.

USB and RS-232 Adapters for I2C built from a single handful of commonly found parts where necessary.

CANBUS parts and components scavenged off cars and wired to RS-485/RS-232 on the PC

Simple optical isolators for lines built from a handful of parts.

... so far, I have had to break with these guidelines in a few cases. For example, I use a custom PC/104 board to monitor up to 48 incoming optical lines that are supposed to be hooked up to seismic sensors one of these days. I bought two spares of this board in case the first ever burns out. I hope at some point to develop a multiplexer for a serial line that will determine which sensor went off with a much simpler optical sensor array.

The idea behind it all is that even if your shelter is destroyed, you lose all your equipment, etc. with a single USB or flash card you can get the entire system up and running again very quickly just from things scavenged in the ruins. This is also why the hydroponics rack is being built as cheaply and simply as humanly imaginable, so if I need another one, I know exactly how to make it from whatever I can scrounge together.
