I took 50 more earlier today when they had their rewardzone triple points deal for invitational store opening at 8:30pm till 10:30pm(?) They had all their cashier opened but I managed to make a friend and stayed at one cashier for the longest time due the upc barcode not scanning. Well that person didn't mind either for she is on the clock for hourly pay. Took a whole hour to finish and I was able to stick around long enough for their raffle drawing every 15 mins. I didn't win but they took my picture for their employee or corporate bullentin monthly newsletter. I'm going to be famous someday thanks to fatwallet.

Yeah, that's not why they took your picture. I'm sure your picture pops up when they have devil customer training for their newbies now...

thanks for the tip on how to benefit from these roboshop giftcards

I'm going to put one on the back of my windshield reading "WHY FOLLOW IM LOST"

or will fatwallet pay us something if we road advertise for them?

These things are awesome! Thanks OP for letting us all know!

Well, I'm not sure, but it seems like this uses FRAM and not EEPROM. Looking at the RAM on mine, I found the number FM24C16 on it. A Google search seemed to bring up the schematics. Link to FM24C16 info

For those who want to hook this up to an external battery, look to the left of the battery. There should be four metallic spots all connected (negative terminal) and one to the right of those that is separate (positive terminal). I don't know if you can just hook up two AA batteries to this without doing any damage, but I did that to mine and it seemed to work.

The question everyone's been thinking of: Can it play doom?

I, for one, welcome our robotic gift card overlords.

I picked up two. Thinking of going back and getting more.

PHISHBONE said:These things need a 3v source. A pc has a 3.3V rail, anyone know what resistor will bring 3.3 down to 3? Thanks....70 ohms 1/8W

Anyone with l33t h4x0r skillz adapted a battery pack to this? IE: Double A's or a 9-volt?

I tried simply connecting a Double A to the terminals to no avail, so I assume you would need to use a resistor or something to drop the voltage of the battery down to 3v???

Dude, one AA is not 3 volts. It's 1.5 on a good day. Try two of them. If you are using rechargables then it might only be 2.5 or so. But anything in that range is fine. People worried about dropping 3.3V down to 3V to get this to work are worried about nothing.

Also, if you really want to get courageous, you might even be able to hook up the device to the 5v power and ground from a USB cable along with a resistor. Then put it on your case for a nice "My 1337 Box" message to appear when you start it up.

A much more long term goal: As for me, I'm trying to either figure out how to reprogram the memory or just directly change the output. If anyone has any experience writing drivers maybe we can also get this thing hooked up to a simple program... but that's getting way ahead of myself.

Aside from batteries, has anyone been able to do anything remotely fancy yet?

I read your post and gave that line to the cashier today. Picked up 20 of them for .01/ea. The cashier asked me how much and I said "I only have to do a penny right?" he said yes. VERY nice guy.

I had the cards in a basket and emptied it on the counter. I held them with the backs up while he scanned then threw it back in basket. Together it only took us about 3 minutes.

Everyone in the household has played with one now.

THANKS OP!!! AWESOME!!!
