Bluetooth Relay Switch Cost

Here is a list of the items I used to create my bluetooth relay switch:

• Electical Box - $0.44 - Here - at Lowes
• GFCI Electical Outlet - $16 - Here - at Lowes
• Extension Cord - $1.67 - Here - at Lowes
• Beefcake Relay Control Kit - $8 - https://www.sparkfun.com/products/11042
• ATtiny85 AVR 8 Pin - $3 - https://www.sparkfun.com/products/9378
• Bluetooth Modem - BlueSMiRF - $40 - https://www.sparkfun.com/products/10269

The total cost of this project comes to about $70, but keep in mind that this is the bare minimum material to create a remote relay with Bluetooth .  I used a breadboard, so you would need to find a box to put it all together and make it nice and neat.  Also, I used batteries to power the ATtiny, Bluetooth, and Relay Switch.
