Budget STK 500 Programmer ATMega128 ATMega 8 ZigBee Chips Temperature Sensor IR Sensor Components Magnetic Sensor Broken Glass Sensor PCB Passives (Capacitors, Resistors, Inductors) Connectors/Jacks Power Supplies Alarm Lights Alarm Siren Buffer Budget TOTAL $85 Sampled $24 $5 $90 $200 $60 $25 $35 $15 $10 $450 $850

27. Project Modifications 1. Main types of sensing are daughter boards rather than all on one motherboard *Easier to break down piece by piece *Easier to debug 2. We have purchased power supplies rather than building them *For convenience *Time constraints *New allowance in budget

28. 3. Ethernet is on a separate daughter board *Allows for easier debugging and block break down 4. Looking into two different types of Zigbee wireless chips *Allows us to test to see which interfaces better Project Modifications
