SparkFun will be closed on Tuesday, November 5th to support our team in being able to go out and vote! Orders placed after 2 pm MT Monday, November 4th will ship on Wednesday, November 6th. Thanks for your patience and understanding.
Back in April, I made a post about Abraham - The Dicecreator - and his dice that were "electronics-themed." On each side of the dice, Abraham had created a different portrayal of an electronic component. We really liked them and wanted to share.
Abraham's electronics dice.
Well, as luck would have it, Abraham is a pretty dang cool guy - and he fashioned up a SparkFun die and sent it to us from Spain! Now, the SparkFun die isn't for sale (though you can buy other dice on his Ebay page), but it's just too cool not to share. He also sent us one of the electronics-themed dice for good measure. Thanks Abraham!
Before anyone goes "Pooh, pooh" to the SparkFun die; it is NOT simply the flame on each side. Oh, no. If you had bothered to take Electronics of 17 or more you would have noticed that the flame is NOT the same color on each side.
You see, Abraham was MUCH more cunning that that! Each flame was painstakingly baked on with one of 6 different carbon film mixtures. If you would take a meter and measure the resistance from the base to the tip of each flame you would get the following readings. (+/- 10%. Hey, it's HARD making these!)
10k Ohms
22k Ohms
33k Ohms
39k Ohms
47k Ohms
1M Ohms (Hey, it's SparkFun. There SHOULD be something SPECIAL for a critical success!)

Now that's just brilliant, thanks for that vital extra information that makes this go from 'meh' to 'awesome!' My only worry is that constant probing to figure what you rolled would chip the coatings off after an extended session.
I think the only way he could have topped that is to have a minature RFID token embedded on each side, and a very lossy (short-distance) antenna be the table you toss it onto, that way it reads whichever token that lands on the bottom. The lossy antenna is to prevent the further-away tokens from being read and jamming the signal.
Or a table with lots of contacts arranged in a tesselating triangle pattern.
The correct distance apart so that at any time, the flame only touches 2 contacts, and just measure the resistance between those two.
Upon further thought, I realize you might be able to do this with the contacts groups into 3 sets hardwired together. Like:
1 2 3 1 2 3
2 3 1 2 3 1
1 2 3 1 2 3
2 3 1 2 3 1
(pretend those are organized nicely)
Then you just have to measure the resistance in 3 combinations, only one combination will actually have a connection.
This probably would not work, but it would be cool!!
Okay, pretend that in that diagram that the rows starting with 2 are slightly off centered, (so as to get the tesselating triangle pattern) the spaces I typed didn't show up right.
Now if only I had a SparkFun D20!!!
"Sir Arduino must roll resistor + SFE flame or greater to survive the ESD attack."
haha that's great :)
Come on guys, this is SparkFun - what about squeezing in a 3 axis accelerometer, FM xmitter, AT tiny13 & battery!!!
And then heading to Vegas??
Awesome!
It would be kinda cool if Sparkfun carried some of these. Specifically I like the electronics one. The Sparkfun one is awesome too but I'd have a hard time using it!
Ebay is cool and all, but if sparkfun carried it I could impulse buy one on my next order! :)
