Lego NXT Wot-Wot Biscuit Barrel Alarm

!±8± Lego NXT Wot-Wot Biscuit Barrel Alarm

The Wot-Wot Biscuit Barrel Alarm features my Lego Mindstorms NXT High Voltage AC Appliance Controller which allows you to turn on-and-off your Household mains powered equipment such as lights, radios, heaters, etc. via your Robot. Using this Controller in conjunction with a Lego Temperature Sensor you can also control your aquarium, and even as a incubator control to hatch out bird eggs. The appliance is switched on and off using an Optically Isolated TRIAC (Electronic Relay) to safe guard the NXT from damage. You treat the controller as a standard Lego Light Sensor. The controller uses the software toggling as used for a standard Lego Light Sensor LED switching from reflected to ambient light sensing. This project needs a lot of care during construction due to the Voltages involved. 120-240V AC KILLS! Only for experienced hackers. For SAFETY the NXT 240V AC Appliance Controller has to be fitted into a suitable electrically isolated case.

Der Kaffeecontroller 1.0 entstand zwangsweise, nachdem ich die Originalplatine meines Senseo HD7810-Kaffeeknechts bei einem Experiment zerschossen habe. Nun steuert ein ATtiny26 die Pumpe und den Boiler über zwei BT136-TRIACs in Verbindung mit jeweils einem MOC3021-Optotriac an. Eine RGB-LED informiert den Konsumenten über den aktuellen Maschinenstatus. Die Bedienung erfolgt genau wie beim Original über die drei Taster "1 Tasse", "Power" und "2 Tassen". Im Gegensatz zum Original speichert die Maschine übrigens den Kaffeewunsch, falls beim Druck auf einen der beiden Kaffeetaster die Wassertemperatur noch nicht erreicht ist und stellt den Kaffee bei erreichter Betriebstemperatur dann sofort her. Es hat mich immer genervt, dass die Originalschaltung dies nicht konnte. Wasserstand und -temperatur werden über einen Hallschalter und einen NTC vom Mikrocontroller erfasst, zur Ansteuerung der TRIACs besitzt die Schaltung eine Nulldurchgangserkennung. Die Software wurde in C programmiert. Prost! Der Kaffeecontroller 1.0 im geschlossenen Gehäuse, bereit zum regulären Betrieb - siehe Part 2: www.youtube.com I was forced to create the coffee controller 1.0 after in an experiment I destroyed the original pcb of my Senseo HD7810 coffee machine. Now an ATtiny26 controls the pump and heater using two TRIAC's BT136 coupled with an opto-TRIAC MOC3021 each. A RGB LED informs the consumer about the current machine status. The coffee machine is being operated by three buttons "1 cup", "power ...
