PICAXE variable map

After I spent some time on excel devising a decent variable map for the PICAXE 28X2 I stumbled on this one that I attached. It's not perfect, and it has extremely small fields to write in, but it's served me well. May it serve someone else equally.

If I remembered where it came from I'd give credit where credit is due but Google couldn't remember either.

This is my first attempt at building a robot. A very simple Photovore. As we don't get much sun in our house, I had to use a torch to make the video. This is all … Read more
Hi all ! That was my first robot, a few months ago. I wanted to start from scratch, so no micro-controller here ! It is a simple photophile robot, but it was a way … Read more

My Project

I wanted to post a new video of my robot on here, but I didn't want to keep moving my project to the top of the front page, so I'll post my video here.

I used this music, because it's called Bring Me To Life

 

 

Adjusting for air/water current

First a terminology question:

What do you call the direction a boat/plane is pointed?

Yeah it is a silly nit, but I am documenting a design and people will pick nits. A simple example is a boat crossing a river. For simplicity, consider the river flowing from N to S and boat crossing from W to E. So the bearing/heading is E. But if point the boat due E you will go SE, so you have to point the boat NE. When I learned to kayak, this was called ferrying and the angle was referred to as "set", but I hate using such an overloaded term.

Hexapod Circuit Diagram & Code Problem

Hi guys. I had to make an hexapod for a school project, and I've decided to try this one http://www.webx.dk/robot-crawler/robot-crawler.htm because it meets all requirement.

3 new projects

I have started 3 new projects. I mainly wanted to use the laser cutter at school before the school year was over. So I made these things which I will be fully constructing in the upcoming weeks. I just threw stuff together for some photos.

nanoDuino, sumo and soccer bots

Hi Everyone,

I'm starting with some new projects.

The first one is nanoDuino, an ultrasmall arduino, based on patrickmaccabe's one. This one has all the input and output's pins broken out and the sockets for FTDI and ICSP cables. It is 18,5x20,5 mm:

TRDI Flying Ball

The first thing I thought was it's missing a cheap syringe to make it the IT-O interrogator droid from that fragile Death Star:

Still badass though!
