Another year of weekly TechVideos starts. Let me write some words today, about a TECHNIC/MINDSTORMS MOC, from Ricardo Oliveira (a fellow PLUG member).
It is a Vending Machine, which already got some versions and modifications. First it was at some Club meetings and BrickJournal (Issue 7, Volume 1 - Spring 2007, pp 67-69). More recently and after the last modifications, Ricardo also took it to LEGOWORLD 2008 in Zwolle, during last October.
Across time it got several transformations, being the main ones for the last version: Double RCX control, replacement by single NXT control; Use of some Mindsensors stuff and insertion of a two selectable drink dispenser which pumps the drink of your choice, into your cup (see the details on the video below).
Among features of this Vending Machine, we have below some examples:
- accepts real coins (Euros).
- calculates and gives exchange.
- keeps record of still existing products and coins to give exchange.
- sorts every inserted coin into its appropriate draw.
- opens the coins drawer, upon insertion of a predefined passcode.
Ok! It has some non-LEGO parts in it...
You may find additional photos from Ricardo's work, at his BS folder.

Among friends, Ricardo's Vending Machine is also know by the "Poison Machine". Says the bad speaking, that once at a club meeting, Ricardo filled the machine with some out-of-date snacks and unfortunate guys got the trots...
Good work Ricardo!
Now you don't have anymore excuses, to not come and read every new TBs post.
