-==About Me==
+== About Me ==
+I hack on robots, embedded systems, bicycles, [[User:Justin/Brews|beer brewing]], CNC machines (3D printers, routers, etc.), and the hackerspace itself.
+I'm also the president at PS1.
+== Current projects ==
+=== Fabulous/Mini Fabulous ===
+Fabulous is a robot I built to compete in Robot Riot on December 9, 2015 at Geek Bar. Fabulous won that competition so bad that they had to create a new rule to kick Fabulous out in the next competition. They put on a weight limit of 7 pounds for the next Robot Riot (Fabulous probably weighs 20-30 pounds). In light of that, I'm working on a new robot for Robot Riot II. It's called Mini Fabulous because it's supposed to be a miniature version of Fabulous. Robot Riot II will take place on January 23, 2016 at Gaming Under the Influence. It will be [http://theguishow.com/robotriot/ live streamed] allegedly.
+==== Features ====
+* GDS (Glitter Dispersal System)
+* Remote Control!
+* Glitter Blister Skin (the robot bleeds glitter when it gets hit by other robots)
+* Chest Burster?
-I like to hack on robots and embedded systems.
+=== Control of Robot Arm ===
+Someone on the public mailing list sold me a pair of robot arms for $150. It was a sweet deal so I took them. One of them has a controller to move it manually. The other one came with a handful of stepper drivers.
-==Current (as if I would actually keep this page current) projects==
+* So far I've gotten the one with stepper drivers to move all its joints at the same time using an Arduino and a fancy stepper driver controller library.
+* I'm working on adding limit switches to each joint so I can move them to a known position at power on. So far I've managed to install two.
+** The first one was on the elbow.
+** The second one is on the shoulder.
+** I'll probably do the base next. I've had a few suggestions for how to do it.
+** The wrist will probably be the most difficult. I'll probably actually attach the switches so that they'll be triggered by the brass turnbuckles on the cables.
+** The gripper already has a switch for detecting when it's closed, so I can use that.
+* Once I can home the joints, I can add additional control software on top. I plan on working out the full inverse kinematics, then programming the bot to do things like block puzzles.
+* I may even add a camera above it for some more fun! :-)
-===Explorations of Silicon Wafers under the [[Leica S430 Scanning Electron Microscope|SEM]]===
+=== 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 uses the [http://www.vending.org/images/pdfs/technology/mdb_version_4-2.pdf MDB protocol].
+** I've proven that the bill validator does work and I have been able to enable all bill types and accept money.
+** I'm working on putting all that I've learned so far into a library for the Arduino.
+** The code for the library is [https://github.com/justintconroy/MdbBillValidator available on github] now, albeit still as a work in progress.
+* Currently I need to create the user interface and the database stuff on the backend. It's a lot of stuff I've never done before, so this part may take a while.
+* Whenever someone figures out RFID stuff, it'll have to work with that, for convenience and whatnot.
+== Sidelined projects ==
+These are projects that I'm technically still working on. I've realized that in order to actually get anything done, I need to focus on a single project, finish it, then work on the other projects. So I'll get back to these projects once I finish the project in the '''Current Project''' section.
+=== Quickbot ===
+* Taken from the Coursera Control of Mobile Robots MOOC: https://class.coursera.org/conrob-002
+* I'm building and programming this robot as I follow along with the course.
+* Sort of sidelined right now because of problems flashing Linux to the BBB.
+=== 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.
+=== conbot ===
+An IRC bot, written in LISP. It doesn't really exist yet. I'm teaching myself LISP and making this bot at the same time.
+=== 3D printed humanoid robot ===
+* The design comes from http://www.inmoov.fr/
+* So far I've just printed a couple of parts for the left hand. I haven't bought any of the non-printed parts yet.
+=== 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.
+== Want to work on ==
+* Learn to weld and/or braze to build bicycle frames.
+* Drink Mixing Robot: http://yujiangtham.com/2014/05/25/build-your-very-own-drink-mixing-robot-part-1/
+== Old Projects ==
+=== End Grain Cutting Board ===
+Eric B. taught a class on making end grain cutting boards. I took the class to learn how to make one. It ended up looking very nice. It was a Christmas present for my momma. I might need to make another one for my sister. I should probably put some pictures on here.
+=== Laser Turret ===
+For this project I was planning to use an Asus Xtion Pro connected to a Raspberry Pi and some servos to build a laser onto a turret and have it track people. It would play some sound effects from the portal turrets to make it more entertaining. I managed to get OpenNI to compile on the Raspberry Pi, but I found that the Nite libraries, which actually do the user tracking I would need were proprietary, and thus I got stuck on this project. It looks like OpenNI might actually be dying now, so I don't know if I'll ever continue this project. I was really hoping I would come back to it in 6 months or so and find that they had either open sourced Nite or that they had at least provided a binary blob for the Pi. Oh well. Maybe I can try to use Point Cloud Library instead.
