+===Automatic Cash Membership Dues===
+I'm working on hacking a Bill Validator from a vending machine. The end goal is to hook it up to a simple interface and the membership database so that people (like me) can pay their dues in cash and have it credit their accounts automatically.
+Quick Facts:
+* I'm using a CoinCo MAG32SA Bill Validator that I bought off of eBay.
+** It might actually be defective, but I've been making progress on actually communicating with it.
+** It uses the [http://www.vending.org/images/pdfs/technology/mdb_version_4-2.pdf MDB protocol].
+** The code will eventually be on github.
+** Whenever [[User:Hef|Hef]] figures out RFID stuff, it'll have to work with that, for convenience and whatnot.
+===SmartRap===
+I'm working on building my first 3D printer with my coworker, Joseph. It will be based on this: http://reprap.org/wiki/Smartrap_mini . We ordered parts from Misumi using their discount they put up on reddit. We still need to budget/buy the rest of the parts (electronics, motors, hot end, etc.) and print out the printable parts.
 ===Explorations of Silicon Wafers under the [[Leica S430 Scanning Electron Microscope|SEM]]===
 * I've already viewed the top layer of a wafer and taken some pictures: http://imgur.com/a/1DcJo
 * The next step is hopefully to get the [[LapMaster]] running so I can grind some layers off and see actual components.
-===Some type of cash accepting system for paying dues at the space===
+* This project is basically on standby until I can figure out the lapmaster stuff.
-** Currently just in research stage, I'm determining what type of bill acceptors I can buy and how what means of communicating with them exist.
-** A couple of standards exist, I'm still not sure if one is a subset of the other: MDB, ccTalk.
