Hi. My name is Eddie Leighton and I live in a historical small town called Lichtenburg in South Africa. I enjoy designing and building simple electronic projects , technical computer programming , hobby robotics and amateur radio. I have built two robots so far , my latest one is a robot lawnmower shown on my web page.

Hi all,

I have posted a more professional circuit diagram of the Mach 2001's motor control circuitry on my web page.

I must still document the input processing of the PIC16F84 Micro Controller , that will be published in due course.



This past weekend I gave the MACH 2001 Model II some finishing touches. The top and front covers were sprayed with gold metallic paint and that produced a lovely finish.

The sensor input programming on the PIC Micro Controller is the next step. This takes the form of interrupt processing , I must just make the time , I'm very busy training for long distance running and that takes up a lot of my free time.

I had a look at my web page stats today , and it is quite apparent that software does not seem as interesting as the robot itself? Programming the PIC is quite a rewarding challenge and it can be applied to everyday life in controlling things around the house too.

I will post some pictures in the near future of the MACH 2001 Model II clad in it's shining armour!

Hi all,

It was a wonderful feeling to see that my PIC16F84 micro contoller worked after been programmed with a simple program written in assembler using the MPLAB development IDE from Microchip.

I use a programmer based on david tait's design. I originally had errors saying "Impossible address" but I managed to get hold of a new and better version of programmer software namely PIC84V05.ZIP and it performed well , the programming action takes less than 1 second!.

On my web site is an example PIC program which I used for the test. Have a look and hey .... let me know what you think of the MACH 2001 and the Model II. Any suggestions or comments are most welcome.

Hi all,

I have not been on this web site in quite a while. I was away on holiday and really had quite a good rest. A rest can do wonders when thinking of robots.

I was quite fortunate. While discussing my robot lawnmower with an old school friend , the conversation moved to PIC controllers. Gone are the ideas of using C++ and Linux on the 386 PC controller , I'm going to throw all that out , create a more compact robot and use a PIC16F84 to do all the work! Of course I will have to program in PIC assembler using MPLAB but it seems to be a worthwhile direction in which to go!

Any suggestions on software and hardware using the PIC16F84 would be most welcome.

My old school friend even donated a PIC programmer and IC (Man am I grateful)

Okay just a short message to say Hi

Hi all,

As promised , I have posted pictures of the new MACH 2001 Model II on the web.
