Quiche (Symbolfoto) by ImipolexG

Teig:

Belag:

den teig durch starkes kneten vermengen. beim mürbteig nur ganz wenig wasser verwenden, das kann sehr bröselig sein und lange dauern. danach kühl stellen, oder wenn der teig trotz warmer hände noch kühl ist gleich ausrollen und in eine quiche-form geben. ich schneide immer dünne scheiben auf und presse diese dann mit den fingern in die form bis ein durchgängiger boden entsteht.

* als belag eignet sich fast alles: jedes gemüse, schwammerl, speck, etc. alles am besten aber vorher in der pfanne anschwitzen, damit es nicht in der quiche zu viel wasser lässt. ausserdem nur zutaten verwenden die schon durch gekocht sind.
weiters die eier im schlagobers versprudeln und etwas muskat hinzufügen.
den hauptbelag in die quiche-form auf den teig legen, den schlagobers mit den eiern darübergiessen und zum schluss den geriebenen käse drüberstreuen.

dann das ganze für etwa 20 minuten bei 200°C in den ofen.

der klassiker ist die quiche loraine:
gleiches rezept wie oben und als belag nur ausgelassene speckwürfel (150g). hier empfiehlt es sich in teig und schlagobers mit salz zu sparen, da der speck recht viel mitbringt.

guten appetit

recently i finished my latest project: a RFID Door Opener.

besides the fun while hacking it, it improves the security of the door. since it’s not an outside door but the door to the garage, it’s construction does not allow to mount a more secure lock. so locking it from the outside when leaving is a bit bothersome.
the new auto-lock feature, which allows the door to auto-lock itself, saves some time and works around the lazy user, who wouldn’t have locked it.
additionally it is now easy to add or remove the right of access by adding or deleting the RFID’s unique number from the system. revoking someone’s right of access is far more difficult with a normal key.

beside an arduino i’m using an easydriver to drive the stepper and a RFID reader from seeedstudio.

below you can see the schematics of the setup. the ends marked with Ard X go to a port of the arduino, which is the brain of the lock:
