Receiver almost complete

admin — Wed, 09 Jun 2010 14:22:39 +0000

The receiver which will be put into the car, is almost complete.
The prototype sender is ready as well.
Now I need to make some tests regarding range, time to get data flowing once the physical link is up and how deep we can put the XBee modules into sleep.

XBee Modules are working!

I received the pcb’s and could make some tests with the XBee Modules.
The connection is working, but seems slow.. need to investigate this.
To test them, I connected both onto my XBee-Arduino Shield (selfmade) and put the Arduino CPU’s in permanent reset state (GND -> RESET) so the Arduino acts as a connection to the USB-Serial Adapter.

PCB’s ordered

The first set of PCB’s is ordered.
An adapter board to mount the XBee Wireless module and the arduino pro mini, including a small circuit to interface the shock sensor.
Second, an arduino shield to connect the XBee Wireless module to a standard arduino duemillanove board.

Arduino Project: open car by approaching it

admin — Wed, 28 Apr 2010 15:38:17 +0000

Well my car is not the newest – so I still need to open it by key or a remote with buttons. But the buttons of the remote are almost gone. the door lock is not soo god anymore, in winter it freezes sometimes.

Now I will try to build a motion-activated small arduino-xbee based remote. which still should be cheaper than buying a new remote And as I got infected by the microcontroller virus over 10 years ago by playing around with Siemens 80C537 controllers – I have to build it by myself…

planned is to use
- arduino mini pro (ATmega 328P)
- xbee
- self-built adapter board (like a shield)
- motion detecor (either a SCA-3000 – with 27chf quite expensive – or a mechanicel one, see distrelec.ch part number 647393)

stay tuned, more will follow…

Fully Automated Nagios, based on CentOS, includes

· Nagios : core monitoring application;
· Nagios plug -ins : plug-ins to monitor different equipments;
· Centreon : Web interface for Nagios (Centreon is one of the best for this purpose!);
· NagVis : advanced mapping (geographical, functional, by services…);
· NDOUtils : stores the Nagios data into a MySQL database;
· NRPE : makes it possible to monitor the Windows servers (the NRPE daemon is not
provided);
· NaReTo (Nagios Reporting Tools) : reporting tool (availability report).

Wir sind am Ostersonntag am Morgen früh auf den Bachtel und haben uns den Sonnenaufgang angeschaut.
