More info than you'll ever want to know about current LED technology

This is a great read if you like knowing about the current technologies going into the components we use to build our bots or other gadgets. It's heavy on the technical info just as an fyi. 

While reading it I was also surprised to find the company that makes those luxeon LED's have some damn cool tech.

 Enjoy!

This may seem like a corny challenge, but I'm hoping to see some Amaizing submissions!! Anyway, on to the challenge. You can create tracked, wheeled, crawling bot, … Read more

Guidelines for new users and first time posters - aka newbies

A while back I think there was some talk about having a questionnaire  or test when a  new user signs up. I, at first did not agree with this but as more and more newbies join, I think that this may be a good idea if nothing, to instill some ground rules for said nubes.

I know this forum is super kind to all of it's users but as of late we've started to see postings that in some peoples(mine) eyes are unnecessary and in some cases downright silly.

mini ir beacon

So this is the mini ir beacon I've had mulling around but never got around to building one....or finally built it. I'll post the current code for this in a bit.

The circuit is pretty basic in that it just uses a picaxe, an ir emitter, led, some resistors and a npn transistor. Ialso wanted to keep it small(hence the mini) so decided to use some lr44 batteries to get around 4.5v out. The battery holder was fashioned out of some 18ga colid copper wire which does a great job of holding things together.

Props to the Arduino

I found this article and thought all of you Arduino guys would appreciate it...

I have to say though I give props to both the Arduino guys and the picaxe guys as they have given us this great tech thats easy to use. I think articles like this help to inspire us when we may not be totally "feeling it"...which happens to me on occasion..

What are the thoughts on source code managment for projects hosted on LMR?

I'm just throwing this out there, because we could all share our source(for those who want to) as well as keeping backups and shareing knowledge.

Since the source code is usually smaller than most images that are posted, it wouldn't add that much space ot the current load that the servers have. This would also be great for collaboration efforts for a lot of the folks here.

 

Any thoughts, possibilities??

Some file SCM's are SVN, Mercuial,  GIT

bluetooth com and processing language rig

These are the source files related to the setup I mentioned in CTC's post about wireless serial com.

 

Reposting info on the setup just for ref.

Alrighty, ctc, got the rig working. The setup is the following:

<ir beacon> transmitting byte sequence from 1-9

<relay station> picaxe 8m with ir receiver showing correct data in the debug window.

Transmitting the byte sequence received from ir beacon via bt to my desktop running the processing code.

Modifying picaxe8 proto boards to fit your needs.

Since my projects contain a lot of 08m procs, I decided a while back to grab a couple of the proto boards for for fun and experimentation. With these boards I also wanted to be able t o reuse them after doing some experimenting with them as we all know desoldering can be a chore.

So here are a couple of ways I'ved moded the proto boards.

1. Choped the proto side off of the board, added a set of male header pins and rewired the power lines. Also used the proto side of the board for a 6+v to 5v regulated via ldo reg.
