House Electricity Usage Measured via Phidgets & Nokia 770 is an interesting project. I wonder how one could make this project work with an old electromechanical power meter.

It 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

Today 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?

AlphaGrip - your next typing device?

Saturday, December 01 2007 @ 22:37 CET

Views: 578

Is the AlphaGrip your next typing device? The current model is called the AG-5. What is it exactly? According to the FAQ at the website (AlphaGrips.com) the AG-5 is, at its core, a USB keyboard and mouse. It works with any operating system or device that supports standard usb keyboards and mice. The AG-5 generates all the characters of a standard keyboard except for Scroll Lock and SysRq. The downside is (of course) taht you will need to spend some time to learn touch typing with this device. And as most of the keys are on the underside (backside) of the device, you will need to do touch typing, because you can't see the keys. But the company claims it is easier to learn touch on the AG-5 than on a qwerty keyboard.
