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 🙂

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):

WD20EADS, WD20EARS, WD15EADS, WD15EARS, WD10EADS, WD10EARS, WD8000AARS, WD7500AADS, WD7500AARS, WD6400AADS, WD6400AARS, WD5000AADS, WD5000AARS, WD1000FYPS, WD7500AYPS and WD7501AYPS

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: http://www.tinyclr.com/downloads/Component/FEZ_Components_Piezo.cs. So here’s the code:
