Let's Make Robots!

This is a great program for beginners such as myself. :D

Those of you who get Robot magizine prolly already know this. But for those who dont check out this site for Robotics training.

Start here of start heres

I stumbled on this site from a link on the nasa page as was drawn to the community developement that happens here. I've seen a lot of the robots on the site, as well as started ordering parts for my start here robot. However the catch is that i know nothing of C++ or robots in general. Im in highschool at the moment and havent been offered courses on electrical engineering, or robotics but it has always been one of my foremost dreams to build robots. While looking around the people here make it seem easy, building large robots, or programming hundreads of lines of code.

"Pedometer" for roller skates?

So as I mentioned a few months ago, I'm currently training to join a local roller derby team. I am, for lack of a better word, quite out of shape. I can only afford to go skating once a week, and want to make sure I am getting the most of my sessions.

I've seen pedometers for runners, and even small GPS units for skaters going outside, but what if you're inside?

How to implement a common ground

I have successfully transfered my SpeakJet module off the breadboard and onto some vero stripboard. I could power the SpeakJet module and the PicAxe module from one shared battery pack, but I'm wondering if it is possible to power each module separately with battery packs at different voltages (nominally, 4.5v for PicAxe and 6v for SpeakJet). The PicAxe communicates with the SpeakJet over a single wire. Do I simply need to connect the ground (0v) of each module together, or is there more to it than that?

Introduction - Saying Howdy!

Howdy folks,


I just joined the group. I've been reading up the blogs and first robot experiments from others for just under a month now. I must admit, I am hooked! And I am looking around where I live (Perth, Australia) for PICAXE starter kits to give it a shot! 


I did find the *where to buy picaxe* link in the home page mighty useful, though there arent any stores here in Perth that I can walk into and walk out a happy man! 


Have a question for you programmers like me out there! OOPic

I have googled this but am unable to find exactly what languages this IC supports... OOP (object oriented programming) is such mostly from libraries. What language does this support? Is it more scalable from the Picaxe basic. I do C# and Java and do it very well for 5 years. If I can use those on this Pic with its firmware that would be awesome. If its just Visual Basic then I will prolly go for the .NET serializer.


Thanks for your info...

Help with IR sensors ~ TIL 38 & 81

I'm trying to set up a IR proximity sensor and these are the only ones available in my area. I have no datasheets or circuit diagrams.

Both are leds: TIL38 as transmitter; TIL81 as receiver 

How should  I connect them to my basic stamp?

hardware not found error


I run the picaxe programming editor on windows XP in a virtual machine (parallels desktop) on my OS X laptop. The serial connection to the picaxe 28x1 works fine when I'm just communicating using hyperterm or when the picaxe sends debug info.

When I want to upload a program to the chip, it usually takes 4 or 5 tries to get it right. The larger the program, the more it fails to load.

So i decided to use the command line compiler for mac OS X. Now the uploads are very stable only a new problem appeared.

DIY wireless, possible or not?

Hi guys!

Sometime ago i had an idea in my mind about a DIY wireless link between, say, two MCUs. But the point is that i never tested it. I just wanted to know what you thought about it and if you think it could work (you are the electronic gurus after all :) )

It should work like this.

-Receiver has the antenna attached to the base of a darlington, and the signal received goes to the MCU (if not enough maybe i could make a bigger darlington, maybe three NPNs)
