If you have problems with a magnetic door contact from your alarm system than the possible reason is a faulty reed switch:

You can test the reed switch with your multimeter (with and without the magnet):

To be sure you can bridge over the reed switch with a short wire:

Someone might say I’m paranoid but i like to now when someone logs into my server.

Copy this into the file “/etc/ssh/sshrc” (Ubuntu/Debian) and change “user@example.com” to your email address:

IP="$(echo $SSH_CONNECTION | cut -d " " -f 1)"
HOST=$(hostname)
echo ''$IP' logged into '$HOST'' | mutt -s 'SSH Login' user@example.com

This example only works if you have configured the Mutt email client.

I got an IBM ThinkPad 340 from 1994 that is in pretty good condition. It has a 8 MB IC DRAM card at the bottom that increases the memory to 12 MB. Here are some details about it:

• CPU: IBM486 SLC 25/50MHz (no Intel)
• RAM: 4MB (max. 12 MB)
• Display: 9,5″ DSTN monochrome 640 x 480
• HDD: 125 MB
• 3,5″ Floppy
• Connections: PCMCIA (Type III), VGA, serial, parallel, PS/2
• Size: 297 x 210 x 49 mm
• Weight: 2,2 kg
• Manual

Here is a small example how you can create timer interrupts with the arduino. For this example you need the TimerOne library.

#include "TimerOne.h"  
int iPin=13;
int iSeconds=1;

void setup() {
	pinMode(iPin, OUTPUT);
	Timer1.initialize(iSeconds*1000000);
	Timer1.attachInterrupt(fBlink);
}


void fBlink() {
	digitalWrite(iPin, digitalRead(iPin) ^ 1);
}


void loop() {
	// nothing to do here
}

With the PSIO add-on for the Playstation 1 you can load games from an SD-Card. It also supports CDDA and XA audio channels and most of the classic games are supported (list). To use this add-on you have to solder a switchboard on the mainboard that will automatically switch between the disc drive and the parallel port.

Here are some images that shows the installation of the PSIO switchboard:
