Hackaday Prize Entry: Vendotron

October 7, 2016 by 11 Comments

A recurring idea in hackspaces worldwide seems to be that of the vending machine for parts. Need An Arduino, an ESP8266, or a motor controller? No problem, just buy one from the machine!

Most such machines are surplus from the food and drink vending industry, so it’s not unusual to be able to buy an Arduino from a machine emblazoned with the logo of a popular chocolate bar. These machines can, however, be expensive to buy second-hand, and will normally require some work to bring into operation.

A vending machine is not inherently a complex machine nor is it difficult to build when you have the resources of a hackspace behind you. [Mike Machado] is doing just that, building the Vendotron, a carousel vending machine constructed from laser cut plywood and MDF. The whole thing is controlled by an Arduino, with the carousel belt-driven from a stepper motor.

It’s not doing anything commercial vending machines haven’t been doing for years, except maybe having a software interface that allows phone and Bitcoin payments. Where this project scores though is in showing that a vending machine need not be expensive or difficult to build, and broadening access to them for any hackspace that wants one.

We’ve had a few vending machines here before, like this feature on the prototyping process for commercial machines, or even this one that Tweets. Sadly few have a secret button to deliver a free soda though.

Age Verification Cameras Easily Fooled

July 2, 2008 by 18 Comments


Nice try, Fujitaka. They manufacture cigarette vending machines in Japan, and were all set to roll out a new system of age verification cameras on their machines, which would scan the face of the buyer to look for sagging skin, wrinkles, age spots, and other signs of legal smoking age. The system is easily circumvented, however: people with a photo of an older person clipped from a magazine can fool the machine by simply showing the photo instead of their own faces.

Another aspect to Japan’s cigarette control is the Taspo card, which is an age verified ID issued to smokers of legal age or older (20 years old is the legal age in Japan). Taspo cards are required for over the counter purchases, and the majority of vending machines require them as well. Relatively few machines are outfitted with face recognition systems, but many more are set to ship in the coming months. Fujitaka claims they are working on a solution by improving the face recognition software, but we think it would be a lot easier to simply check the background of the image. Since the camera is static and always pointed in one direction, the portraits it captures should always have the same background. Someone please tell Fujitaka we just saved them a boatload of R&D money… until Guy Fawkes masks become more popular.
