AVR Mega8 RSS Reader

avr_rss

[Barney_1] built this sereial RSS reader. He’s using the Dragon Rider 500 development board, which is a kit that has expansions available including the LCD, serial interface, and power supply. You don’t need the kit though, you could just build your own with similar specs. He has written a program in python to scrape RSS feeds and send them to the LCD. He’s got some specific workarounds for the Dragon Rider board if you do have one. You can download the firmware and source code on his site.  You can see a video of it after the break.

Kindle 2 Teardown

kindle2

The people at iFixit have shown that they’re still on top of their game by tearing down the new Kindle 2 eBook reader. The main processor is a 532MHz ARM-11 from Freescale. Interestly, there isn’t any significant circuitry behind the large keyboard; it seems its existence is just to hide the battery.

This little wall plug is actually a full computer with 1.2GHz cpu, with 512MB of RAM and 512MB of of flash memory. It comes with versions of linux, ported for its ARM processor. At $50, this cool system could be finding itself in a lot of homes. You can get more information from the manufacturer. What uses can you think of for it?

PropIRC: Propeller Based IRC Client

Many people don’t want to miss anything in their IRC room, so they “idle” or just leave the client open to capture all the conversations. It can be annoying to have it going in the background on your computer though. To remedy this, [Harrison] built a simple computer from a propeller microcontroller that’s only purpose is to connect to IRC servers. It can take a regular PS2 keyboard and works with a standard monitor at 1024×768. It’s compact size and low power requirements make it quite a useful tool to have around if you are always on IRC. you can download the source code and schematics on the site.

Parts: Analog Distance Sensors (Sharp GP2D12/2Y0A02)

[youtube=http://www.youtube.com/watch?v=iGiRK0vmcUw]

Sharp GP2D12 and 2Y0A02 infrared rangers output a voltage proportionate to the distance of an object from the sensor.  The GPD12 senses objects at a distance of 10-80cm, while the 2Y0A02 has twice the range.

We’ve previously looked at the Sharp GP2Y0D02 digital proximity sensor. It only signals the presence of objects, while the GP2D12 and 2Y0A02 measure distance to them. If you’ve got a GP2YoD02, it might still be possible to tap the analog output. We’ll show you how use these sensors below.

Windows 95 Running On An N95

windows

We’ve had this same hack submitted by two people, pointing to two different(translated) sources(translated) today. It seems with a recent version of dos box, you can load windows 3.1 or windows 95 on N95 or N85 devices. They’re both in polish, so they may be the same people posting in different places.  If you can follow along, there seems to be sufficient information to do this yourself. We don’t know why you would want to, but you could. You can see a video of it in action after the break.
