hey guys. i'm completely new to microcontrollers. i'm in a techno sculpture class right now and i want to utilize an arduino to control a gian volcano model. essentially i want to hide rfid tags in fake environmentalist pamphlets. my hope is that most people will disregard them or throw them out. but these RFIDs are supposed to switch on a rumbling effect within the volcano model itself. so only the viewers who care about the "movement" will get to participate.
is this feasible? i mean, i'm a student so i don't have a whole lot of money to spend. but can rfids even do this? and get i get tags cheaply in bulk?
On sparkfun, you can buy RFID tags for 1.25$ a piece, 1.56 for 100+ pieces.
I bet you can find cheaper and more flexible ones so that you can incorporate them on your pamphlets.
Correct me if i'm wrong : you want to distribute your pamphlets at the entrance of an exhibition, for example, so that people who keep the paper with them will be the only ones to activate the volcano ? I'm not an RFID expert, but i guess it could work, even though you don't need the ID part (you don't want to identify each person), so there might be another solution. Those anti-theft copper antennas glued on the back of DVDs and stuff in hypermarkets, what is the name ? That might be the cheapest solution.
