Hooking up a servo to picaxe 28x/40x project board.

   On my current project I am using the Picaxe 28x/40x project board and I don't know where to hook up servos on it.  I searched around on the internet a lot but couldn't find anything about where to hook them up.  Not even the board's manual said.  I don't know if I missed it or what but I can't believe that picaxe would just let you go find this out for yourself.  I even entered the code to center a servo and went around on the board and tried to find were it was.  I also remembered to put a 330 omh resistor on the signal line of the servo.  I

Ipad vs. Laptop

   A few days ago my trusty laptop died.  This laptop was my main computer for years and it was always great for what I needed it to do.  I used it for browsing the net, programming, music, itunes, etc. and it was used hard and a lot.  I went threw many chargers for it and currently the battery holds no charge at all so it was getting close to the time to start shopping again.

Mapping With Picaxe

   For a current project I want to try mapping a room with a picaxe but do not know how to get started.    With this project I want to be able to find my way to certain places in the room and want to be able to know when I got there.  For example I would want to map a room and I would want to be able to set different spots in the room to look for objects.  Then once it found an object in a certain spot it would take it to another predetermend spot.  An example would be if it would find anything next to the foot of my bed pick it up

This is a current work in progress that is waiting for a few parts.    The goal for this project was to make a robot that could go after people with an airsoft … Read more

Is this possible with this screen.

   Okay, after seeing CTC's post (http://letsmakerobots.com/node/27139) which was great, I became interested with the screen he used.(http://www.sparkfun.com/products/10090)  So after a little thinking for what I could use it for,  I decided that I would make it record video from a small camra and show it back on the screen when I signal it to do so.  After that I researched that idea and it looked easy enough, so what I am asking is "Is that possible to do?"

Problems with object tracking using a Dagu compound eye and pan tilt set up.

  Currently I am having problems with object tracking.  My current set up is a Dagu compound eye on a Dagu pan/tilt braket with 2 micro servos in it for turning.  All of that is hooked up to a picaxe 28x1 board correctly, but I run into my problem with my code.  My code kinda worked but was really jerky and will still move when there is nothing there.  Also sometimes it will go like it has a mind of its own.  I thought it was moving when there was nothing there because I made it read the two eyes on opposite sides and jus
