  View Printable Version 
HardwareSoftRock-40 is a small, low-cost "Software Defined Radio" receiver kit for 40-meters, used with powerful software on the PC for multi-mode operation. It's like a low-cost, receiver-only GNU Radio for the 40 meter band. Cool! Ther is also info about a version 5 of the kit. Even more info on SoftRockRadio.org. Other kits at SDR-Kits.net.

PicoLCD

  View Printable Version 
HardwareThe PicoLCD is an interesting device. Display, keys and IR receiver. It plugs into a usb port (ok, it is only full speed, but anyway) and there is Linux drivers and opensource SDK. I think they are supporting LCDproc so this will work with most opensource systems. More info here.

The BUG - another open gadget running Linux

  View Printable Version 
HardwareIt seems gadgets that are open and run Linux are everywhere these days. The newest I have seen is called the BUG from Bug Labs. As they say it on the web site: "BUG is a collection of easy-to-use electronic modules that snap together to build any gadget you can imagine". Currently it lacks Wi-Fi, but it is promised for later this year. I couldn't find anything about battery life either. Also - the whole thing programs in Java.

old gear: Palm V

  View Printable Version 
HardwareToday I found a Palm V in working condition in a pile of junk. It runs Palm OS Software 3.3 and comes complete with cradle (serial connection), flip cover and stylus. It is currently sitting in its cradle recharging the battery. I'm wondering what use I can get out of it. With PalmRemote (shareware) it can be used as an infrared remote control, or I could install Linux (Palm Linux Environment) on it. It is possible to connect a Palm V to a FreeBSD machine, a Linux machine, and probably more. I could run OnBoard C or SmallBASIC on it (or does SmallBASIC require Palm OS 5?). If I wanted to control other machines from the Palm V, I could install PalmVNC on it. I wonder what else It could be used for?
