Let's Make Robots!

I made the usermap work!

Wow, after user # 10.000 or something, the user map did not work for me. By chance I just tried, and somehow it worked (after freezing in 5 minutes)

Here we are: (note that more persons from same city without specific address makes more dots right on top of each other)

Dividing a word into bytes on Picaxe?

Can anyone remember how the heck a word variable is split into individual bytes on Picaxe?

Say I have the word 2234, and I want it to be transfarred serial as 2,2,3,4 .. how?

(I know I have seen this somewhere sometime, just cannot figure out where, and I am going nuts now!)

Thanks!

Idea: A simple way of doing balancing

I was just cleaning up my desk (a little anyway), and found myself sitting with the guts from a servo.

In essense I had:

A potmeter. If it was turned to one side, a motor would turn to one side, and vise versa. A little turning = a slow motor, hard turn = fast motor.

Hmm.. interesting..

Now, what if I was not turning this potmeter, but a simple spinning disc, acting like a simple gyroscope was attached to it?

Then if the whole thing was tilting in one direction, a motor.. OR a complete servo (with guts taken out) would turn to one direction.

Guibot's mothers shaver

Today I got a parcel with the post.

Wondering what it was, it was quite a surprice to find what I imidatly recognized as being Guibot's mothers shaver.

Guibots mothers shaver

Then I realized that about 1 1/2 years ago, I said that I would take it over if Guibot had problems coding..

Radio mast navigator - idea :)

Hi, just got this idea, and thought perhaps it would interest one of the clever guys out there. Hope is that a vendor will take this up, after a couple of clever LMRians have talked more about the details that I am too stupid to get into :)
