Robot Dialogs

So I'll be participating in my first (Mini) Maker Faire next month. I'll have most of the projects from previous posts there with me on display. I don't know exactly where I'll be, probably get that email in the next few weeks. Should be some good projects out there. In the time between now and the fair I'll be working feverishly to finish my GameBoy project . The idea has picked up some new traffic in the previous post's comments and on the forums so I've got some new data and help in that respect. New data is below and I've ordered a logic analyzer so I can get even better info. 1 Frame of GB LCD Data More Data

Quick post of some old video of Spin Cycle ...just now got around to uploading it.

I've been tinkering about with making panoramic pictures lately and when I'm out and about my Droid is the only camera I have. But taking panorama quality pictures with it is pretty tough. So last night I whipped together a very simple tripod mount. It's pretty self explanatory...here's what you need: Wood, I used 3/8" pine from the scrap pile. Small screws Wood glue Drill and bits (1/4" for standard tripod screw) Saw (I prefer the small teeth of a hack saw for little stuff like this.) Paint I had some in progress pics but Windows ate them. Essentially the only part I measured accurately was the slot the droid slides into, other than that it was just eyeballed. Two small screws hold the upright pieces (wood glue also). I used some paint I had from a robot project. Tripod screw threads right into the wood. I spent nothing upfront on this project...I'd estimate cost around $1 of material and maybe 30 minutes time went into it. It fits quite snu...

This is mostly just to get some pictures up. I'm just getting this posted so I can try and refocus on thesis...I should be so easily sidetracked... Any future developments will be posted in the forum first...I'll post here as facts become more concrete. The farthest I got with this setup was a man-in-the-middle setup (as shown below) where I could intercept the CPU's commands to the LCD passing them through the microcontroller and then to the LCD board. I had to move up to a ~11MHz crystal (not shown) on the microcontroller just to come close to allowing the signals to pass through unhindered. The best I managed was a slightly distorted picture...I'll need something faster to actually read the signals so I can reverse engineer them. I've also removed the GameBoy's oscillator so I could clock the GB at a slower speed. This did work but I haven't taken a ton of time to work on the coding side. The goal when I can work on it again is simply to replace th...

This is a dump from the forum...it's notes on an in progress GameBoy hack. I will refine it later. Forum thread is here . I'm trying to identify and spec out the LCD signals in the GB (classic). I'm looking to do away w/ the GBs original controller board while keeping the LCD board. Basically I want to plug the ribbon cable into my on PCB and output the necessary signals to drive the video myself. I'm just wandering if anyone has more info on LCD signals output by the z80 so I can emulate them to display stuff. So far I've mapped all the buttons, speaker, power LED, LCD negative power to the appropriate pins on the ribbon cable. What I have so far: Note: Pin 01 is the pin on the ribbon cable closest to the power switch (at the cables connector). Note: Pin LCDV1 is the pin closest to power switch on the LCDs vertical axis connector (beneath LCD). Note: Pin LCDH1 is the pin closest to power switch on the LCDs horizontal axis connector. Pin 01 GND Pin...

This is an update and rehosting of a senior design project completed in Spring 2008 at RIT . It is (to date) my favorite robotics project. Myself and two friends collaborated to create a remote controlled turret that was accessible from anywhere on the web. The project makes use of a 5 gallon air tank at ~80 psi to fire foam (Nerf) darts. One servo operates six rotating barrels which are mounted on two more servos that provide pan and tilt movement. There are two ultra bright LEDs providing light in dark conditions for a top mounted web-cam. An Arduino is used to control the turret, while communicating (via serial over USB) with a web server that hosts the custom web page and live video stream. A modified PC power supply was used to provide the power. Here's a video of the finished turret... Full System Test I was in charge of most of the hardware and electrical work, Mike programmed the Arduino (I usually work with other AVR stuff ) to take serial commands from a server...

This post is a retrospective look at the first robot I built solely for myself (back in 2008). I had only helped build one robot before this. It's clear I got a very late start into robotics. Although school did prepare me formally to dive right in, I wish I had been more focused on it when I was younger, I would have really flourished in college. This robot was designed mostly on a whim, but has turned out to be a nice solid prototype, and it is very useful for testing sensors and AVR code... The Parts List: Aluminum Chassis, Motor Mounts & Tire hubs - Machined while I was still at RIT when I had access to their machine shop. No original designs are available, I just went in and used what scrap I could find...I'd be embarrassed by providing the true measurements :). Stepper Motors - From Sparkfun ...I may replace these some day with cheaper gear motors so I can use these steppers in a CNC/Drill Press. EasyDriver Stepper Motor Driver - Also from Sparkfun...sim...
