Adafruit Industries gave us a sneak preview of the new digg Button Kit v1.0.
It's a digg button for physical objects. Now you can compare ratings for your stuff, your friends, whatever- digg up what's cool.
We all marveled at the packaging for a while and then after some intense debate as to who gets to assemble it and post an Instructable, the honor was then bestowed upon me. So, allow me to demonstrate...

Step 1: Gather Your Parts and Tools.
Before you start assembling it you should make sure that you have all the necessary parts and tools.
The kit should include:
1 - Atmel ATtiny2313 Microcontroller (preprogrammed)
1 - Generic ceramic bypass capacitor (0.1uF)
4 - Generic 47 ohm 1/4W 5% resistor (Yellow Violet Black Gold)
1 - Generic 6mm tact switch button
1 - Triple 7-segment LED display (Common Cathode)
1 - 20mm Coin Cell Battery Holder
1 - 20mm Coin Cell
1 - Digg Circuit board
Tools and supplies you will need include:
- a soldering iron
Step 2: Solder.
If you don't know how to solder, please visit the Instructable on how to solder.
If you already know how to solder, then the first thing you are going to want to do is to attach the components in the following order:
1) the resistors
2) the capacitor
3) the chip
4) the switch
5) the LED display
This is the order that worked best for me. Feel free to change it up as you see fit.
In case you are unsure, the components simply need to be matched up to their icons on the board. For instance, a resistor would be placed over the picture of a resistor (it is pretty straight forward in that regard).
When installing the chip, be sure to line up the half circle on the chip with the half circle on the board. Once certain of the alignment, insert all of the pins on one side first and carefully and gently apply pressure until the pins go into the holes on the other side.
Also, you should be able to solder the chip in place in under a minute. If it takes longer, take a break and let the chip cool down before you resume.
Step 3: Attach the Battery Holder.
Flip the board over and find the three large metal tabs and the outline of the battery holder.
First you probably should apply a small amount of solder to the middle tab. I did not do this step, but my battery sometimes has trouble making contact with ground and I think doing this will solve the problem.
Once that is done, line up the battery holder so that it matches the outline and solder it so that it is lined-up to the two outside tabs and flush with the board.
Step 4: Clean Up.
Trim all of the excess leads off the back of the board to prevent crossed wires and uncomfortable thumb pricks.
Remember to also turn off your soldering iron.
Step 5: Can You Digg It?
Can you digg it?
Yes, you can!
Put your battery in and go digg stuff.
