Digg Button Kit V1.0

Intro: Digg Button Kit V1.0

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
- solder
- clippers

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.

That is damn cool. I could see this going the same was as the whole ATHF glowie thing...

[mutant]

yeah.... what were they thinkin'.... bombs? Duh.... well it looked like a circuit board. What kinda bomb uses a circuit board? The timer maybe, but not the bomb. ahhhh.... the joy of mass hysteria. BTW do you read 2600: The Hacker Quarterly? They showed err from ATHF on the cover and I think it might be a reference to the whole LED mooninite terrorist panic. Heh... man that never gets old. They should make fun of that in ATHF... I would buy like 6 copy of the DVD of that season.

a bomb and a relief,the bomb's timer stopped! Whew

add a 555 circuit to the button lolz

[raykholo]

Your intentions are questionable here.  This circuit uses a microcontroller with an internal oscillator for time keeping.  Anything you could do with the 555 can be done by modifying the program.  
This is, assuming you know how.  Be warned, the source code is read only.  I have spent some good time with a programmer and AVR Studio and it is impossible for me to rebuild a modified code to burn onto the microcontroller.  As such, my current work is hacking the eeprom in the chip in AVR Studio, not ponyprog because I have a usb programmer.

Good luck.

How?

[mutant]

typo... copies

[mutant]

LOL!.... It's so funny! Everywhere I go, I see something that reminds me of Boston's sheer stupidity. I was checking out your info here on instructables and i found a discussion about sexiest geek. Leah Culver was the first to be nominated. A quick Google search for Leah Culver displays leahculver.com, so i go there. So I read a bit. I want you to go there and read the paragraph entitled "Stuffy Noses". What next... nukes from c++... or maybe a death ray from batch files and and visual basic.

wat dat??

[trebuchet03]

Dat: a digital tape recording of sound

[ReCreate]

that thing in the wall looks like a bomb timer

[Orum]

It looks like you could modify this pretty easy to add a reset button and a reed switch to make an easy counter...Now I just have to order one and try it myself. :)

[macedonian_boystefan]

send to me the scheme of digg button kit v1.0 on my e-mail [e-mail] please I need it please and hury up

[Orum]

You can download it on their site if you need it.

[oldcrowrich]

can i make the digg subtract one from the display?

[Derin]

hey who flagged your comment?

[Derin]

if you want i can make an hex one

[digg italiano]

most funny gadget I ever see :)

[rickyd!]

that looks like a bomb ...beep beep BOOM!

purchased my kit, cant wait for it it come. you buy these from www.adafruit.com its about 18 dollars US.
