LoveBox - The box of love

Step 2 What you need

You need the following things:

• A nice box
• A alphanumeric display
• A microcontroller
• A 74HTC138 (3-to-8 decoder)
• Some resistors
• Two 3-volt batteries
• A microswitch (NC)
• Wires, hot glue gun, soldering iron and other small tools.

In this project I used a box that I stole from my wife, an eight character 14-segment display I got of eBay a year ago, a AVR ATtiny2313 micorcontroller and two 3-volt lithium batteries for cameras.
