Bluetooth windows unlock

hasznos kis progi:

BTProximity is an application for Windows Vista and Windows 7 that can detect when your bluetooth-enabled phone has come into range, and unlock your computer.  When the device moves out of range, the computer is automatically locked.  This isn’t a fake lock window, the computer is locked using Windows Security.

Az  install: btproximity


– The device needs to be paired with Windows first, then it will show up in the devices list.  If you don’t pair the device, secure mode will need to be disabled in order for the device to appear.

– Be sure to install the unlock component if you’d like to automatically unlock.

– Be sure to set the credentials to unlock.

– Setting the check interval too high may lead to poor battery life.

– “Faster Unlock” will unlock as soon as the device has been seen, without an additional check.

– Notification area icon colors:

Gray: Host device is not compatible or not found.

Red:  Device is not connected (out of range)

Green: Device is connected (in range)

Western Digital (GREEN) winyók garanciális idejének ellenőrzése + linux IDLE time állítása

Ezen az oldalon lehet megadni széria számot és már mutatja is mennyi a garanacia hátra 🙂

Az url külön is:

Ha pedig GREEN winyokkal doglozunk, akkor fontos info, hogy van bennük tervezési hiba, ami azt jelenti, hogy túl hamara teszik magunkat pihenő állapotban ami egy szerver esetében, gyakori tányér felpörgetést jelent. Az érintett verziók az alábbiak (cikk és forrás):



Linux alól ezzel a kis programmal (idle3-tools-0.9.1) lehet javítani (SF oldal)

Dell Media Driect 3.5 Codec telepítése

  1. What do you need:
    – Ext2 Installable File System for Windows
    So we can read the file system of the MediaDirect partition in Vista
    – Sysinternals Process Explorer
    – K-lite codec pack STANDARD (not the FULL version!)
  2. Installing Ext2 support for Vista:
    Don’t run the setup by double-clicking it, run it as administrator (Right-click -> Run as Administrator)
    After installation, restart windows.
  3. Now open explorer and you’ll see a new partition with the name “MEDIADIRECT”.
  4. Unzip and rename “procexp.exe” to “taskmgr.exe”.
  5. Place taskmgr.exe on the MEDIADIRECT partition in the“windows/system32/” folder
  6. Place the k-lite setup somewhere on the MEDIADIRECT partition.
  7. Shutdown windows and now start MediaDirect.
  8. When in MediaDirect hold the power button of your laptop for about 5 seconds. This makes sure it wil have to boot up from scratch when we boot it again.
  9. Now start MediaDirect again. While the stripped version from windows xp is starting up, you’ll see a blue desktop for a short second. Here you press “ctrl+shift+esc”, be fast… ;)
  10. ProcessExplorer should start now. In ProcessExplorer click File->Run… and run “explorer”. OK.
  11. Go to the K-lite setup file we placed on the partition earlier, install it and we’re done!

Motion sensing with FEZ Domino

Just messing around with my new FEZ Domino board and I thought I’d post up a quick tutorial on how to use a motion sensor with your board. First thing you will want to understand is interrupt ports. An interrupt port is a port that is listening and waiting for something to happen. For instance voltage levels going up or going down. In this tutorial I use a motion sensor that I got from parallax here. This is a very basic sensor that has voltage tolerance of 3-5v and has one pin that outputs high or low voltage levels. High means its sensed motion. The next part of this project involves a small speaker that outputs a tone to let you know its sensed motion. Nothing loud or anything but just for demonstration purpose. You can get the driver for the tone generation here: So here’s the code:
