Spectrum ZX Laptop


[Jim] sent in this interesting laptop modding project. He started with a Spectrum ZX and a Toshiba Libretto 110. The libretto kept its brains, but the lower case and keyboard was replaced with the ZX hardware. Since both machines use matrix style keyboards (but different matrix layouts) he was able to create a passive adapter circuit to match things up.

Propeller Based UAV Helicopter

I guess we’re on a UAV kick – I ran across this one when I was looking for interesting propeller projects. [Glenn]’s building this one based on a R/C helicopter he picked up. Both the controller and the heli recieved a propeller chip, along with a pretty standard array of navigation sensors for the heli. It’s a work in progress, but sometimes those are the most inspiring.

Suspend In Motion


Reader [Brien Schultz] didn’t like his laptop suspending every time he closed the lid to move around the house or to a different work area, so he turned that feature off. Of course that just led to him forgetting to put the thing to sleep when he really needed to, like when he was walking around all day with it in his backpack. To solve his self inflicted problem (common cause of many hacks) he wrote a .NET program to monitor the laptop’s accelerometer. The accelerometer is usually used to park the hard drive heads in case the laptop is falling (it’s also used for hilarity). If BedTime detects that the laptop is in motion, but is not being used it starts a countdown and eventually puts the laptop to sleep. Brien isn’t using the “sleep after X minutes” option because it would put the machine to sleep while it was open and he was just distracted for a few moments. Demo video after the break.
