OpenSource Money Machine Access Controller Vending maching / money reading / register https://github.com/vahancho/nkar for contour matching shell command "compare -metric RMSE w.png b.png NULL: " https://github.com/tecan/OSMMAC Features 4k camera battery backup/ charging system telephone esp 8285 wifi auditable alarm vibration sensor stepper motor dispensers/ rotate lock bar use transistors + i2c analog pin expander coin weight / lumens for verification dollar bill scanner – pixel matching / contour matching / reflectivity / ir sensor dispenser for keeping arms out of the inside juke box supplied air(shots of air daily with temperature regulator) or air cycler on the unit at specified times when no one is around at random selected spot on the unit (maybe some sensors for inlet temperature/ humidity maybe co2 detector / air quality sensors. smoke dispenser could be setup for public use with remote supplied air somehow if you can seal the dispenser portion from outer contaminates that could end up on the machine. Coin Acceptor https://www.best-microcontroller-projects.com/coin-detector-and-counter.html expired utility patent. coin acceptor made for canadian currency, have not printed yet so may need to be scaled up a bit still. there are a few on ebay for under $20 with (metal looking face is actually plastic). icedcream-bar-vending-machine is composed of a modified freezer turned into a icedcream dispensor. by guess you could net $500 per fill in a good location. https://github.com/netpipe/coin_acceptor arduino project, asfast as you can put coins in it counts them for under 25 dollars CDN easy heating element would be a toaster converted to only use 2 of the 4 elements using roughly 400 watts the change return dish is ment to have a push button to dump it could use some drilled holes where you need them also a pivot point since canadian dollar bills have seethrough spot might use a combination of color sensors and led's/photosensors to make a low tech dollar bill acceptor. something like this https://www.youtube.com/watch?v=DmX0FbBLGqk have designed the alpha concept bill acceptor - uses 2 photosensors 2 led's , ir sensor, limit switch micro(for counteracting the tape trick where they pull the bill back out after might need 2 or 3), and 2 color sensors for top and bottom probing in various spots while accepting bill. https://www.youtube.com/watch?v=_eLimZ2cETw bill dispensor concept some funny ideas for angry/happy vending machines roughdraft yelling vending machine where you have to yell at it for 15 min to get food from it. also face detector for sad, angry or happy face. also might need to shake and tap it consistantly. with free single popcorn dispenser that you have to use your fingers funny to get maybe semi sharp edges. jumping vibration sensors, games like simon or land on the spot while it blinks before you have to talk to it. also a turn the page type metal flap at horse walking speed for racing. also could have nice version with crooked smile face that makes sad feeling and flashes bright light when you say the word food or say things quieter.a pull the handle to play along with the tune fairly hard. also a blink detector that keeps you blinking. and make a low frequency humm while its being used. another machine that uses this concept is the orangejuice shake machine https://www.youtube.com/watch?v=LBgxSmhGbsU
