Title: Science fair bitcoin giveaway Post by: Rachie on February 03, 2014, 07:57:18 PM Hello, I'm planning a science fair which will take place this April. As one of the exhibits, I'm making a bitcoin dispenser. Kids will be able to press a button, and a thermal receipt printer will spit out a code for a bitcoin portion. So far 2000 middle school students are scheduled to come to the fair.
I already have an Epson T20 printer, and a Raspberry Pi to run it. I'll be making a fancy button in a wooden box, which will connect to the Pi. I might have to switch to a laptop instead of the Pi though, as the printer drivers are a pain. The exhibit will also have some posters describing bitcoins, and a presenter to help explain how things work. I've been running a jalapeno miner the past couple month or so to generate coins for the event, though so far I'm only up to about BTC0.05. I'm afraid I got into this a little too late. Could anyone assist me with this endeavour? Mostly I need to figure out the software side. What's a good way to dispense bitcoins? Should I generate a new private address every time the button is pressed? Or should I simply give them a private link to a webpage where they can get access to the coin? I'll have to maintain a secure site though. I'm thinking of printing QR codes, but also including plain text, and a link to more information. Maybe I could include the current USD value as well, thought they might not be very interested once they learn it's only worth a nickel at the moment. There's also the question of what to do if the coins are never retrieved. Kids will be kids, so a good portion of the receipts will probably end up being discarded. Should I tell them to immediately transfer it to a new account, or else it will be reclaimed in six months? Any help would be greatly appreciated. Thanks! ~Rachie Title: Re: Science fair bitcoin giveaway Post by: Colin Miner on February 03, 2014, 09:30:07 PM Hi ~Rachie
https://bitcointalk.org/index.php?topic=320977.0 (https://bitcointalk.org/index.php?topic=320977.0) has a discussion on 'What do you think is the best form to gift BTC?' which my give you some ideas on how to present the BTC gift. I think a custom made paper wallet would generate interest?

But how do I script the generation of thousands of wallets?
