So I'm currently working on a grant proposal for a ticket dispensing machine. It would sit on a desk and look like a really old school ticket machine (I'm a woodcarver/artist by trade so that bit I can nail). The tickets would come out with a little picture of the library/historic site it is located in. I'm currently working to the gumball wheel turning design but I can change that if really necessary.
Now here is where I'm coming into problems
First I'm Australian. I want it to be it to be super cheap (10 cents per ticket) because it is a public art piece (thus needs to be affordable to the public). No commercially available coin mechanism seems to go into that small an amount for Australia. I've tried looking but it's either all American dimes or up to the 1 dollar Australia.
Second it really needs to be mechanical not electrical, because at the end of the day the person who is going to be replacing tickets and fixing jams are going to be shop owners or librarians aka people who are not running arcades and don't have electrical experience. I can be on hand to fix major issues but on a day to day bases they'll need to be able to fix most problems on there own.
As I said in the title it doesn't need to be super secure because it's going to be on a desk (also they are literally worth 10 cents soooo) But it does need to be strong and sensible.
I'm sorry if this has been addressed before or if this ain't the right space but I couldn't find anywhere else to ask. Please Help!
