Minimal Picaxe LED blinker

I just found a different way to make an LED blink with a picaxe 28x1:

main:
   inc b0
   let pin7 = b0 >> 7
   ' do other important stuff here
goto main

Walter Update & Voice Fail

Just a quickie update guys,

My First LMR Blog... first blog ever?

So Im new here...

I have already started my first robot. And as soon as I have got it together to a some what more presentable state I will submit it as a project :)

When deciding what to create as my first robot, I looked at the beginners stuff and thought I could do that, but I still want to be diffrent which is why I am building a 3 legged walker. I'll Hopefully upload a video or two with some photos in the next few hours.

Thanks for reading and enjoy your day.

Love and Peace

Spotted in the Shoutbox tonight. So true, I had to preserve it for prosperity. Also: shouts cannot be Chilled (thank you).

fritsl: This is the only robo-community in the world where ppl thing the others are cool :D

Robot video

Made a short video over the weekend to practice some camera shots and whatnot, I had this guy laying around for quite some time and decided to use it as a subject. The video is more about the camera work than the robot, sadly.

Steampunk Robot

I attended the 2010 Steampunk Worlds Fair in Piscataway, NJ.

This bot took first place at the Mad Science Contest.

Here is a less dramatic, but more in focus picture.

Mini Robotic Ant Farm

I have started the build of the first Drone prototype for my little ant farm project. I plan on building around 4 Drones and a Builder.

 


1. The Drones:

Chassis:

The Drones will be as simple as possible, using TH components, as is hard to prototype with SMD. A double sided, plated holes prototyping board will be used as the chassis. The board is 38mm x 38mm and it can get smaller only if I use a smaller battery.

Power:

The Making of CircumPic

What follows represents my aim at documenting the creation of my yet to be named robot using a picaxe18x for brain and a l293d for motor control. Hopefully at the end i should be able to control the robot via IR and also have the ability to flip into auto mode. Too much to expect from an 18X ? We'll see.

Chris the Carpenter on Facebook

Ok folks,

I have changed my Facebook name from my real name back to my internet name. Up to this point, I have had to keep my Facebook world separated from the rest of my internet worlds. Now that it has been changed, the worlds can collide. So, if anyone is a FB user and is interested in the meaningless crap that I post there, I am:

PCB - The Making of Blaster Shark (Sumo)

The details of why I picked what parts I picked are covered in the Design blog.  What I am about to describe here is the tools and process I go through to design and etch my own PCB.

Circuit Design

Wheels - The Making of Blaster Shark (Sumo)

After the design of the body and motor mounts I can get an idea of what kind of wheels I need.  The things that are important to consider is the width and diameter.  Both are restricted by the dimensions of the the minisumo.  In my case, since the motor shaft is offset, I can go with a smaller diameter wheel and not worry about the bottom clearance of the robot.  But since the motors are somewhat long, I can't go with a really wide wheel.  With this in mind I figured that a wheel diameter of 40mm and a width of roughly 20mm would suffice.

The Making of Blaster Shark (Sumo)

Hello fellow robot builders,

Its been another while since my last post.  My building mojo has been renewed and I am starting a new sumobot.  The Vulcan Five is on hiatus until I can get the PCB replaced.  This time around I am building a minisumo which will compete in the upcoming Western Canadian Robot Games on May 15th.

"Day of the Sun" - St.Gallen - Switzerland - Solar Transport Event

"Day of the Sun" - St.Gallen - Solar Transport Event

St.Gallen hosted an event to generate interest in the "Solar" direction.

High point of the event was Solar Car racing.

School from all over St.Gallen where asked to enter mini Solar cars to race on a track.

The prizes where pretty good incentive too.

My very first CNC project aka "klyCNC"

I have just finished the mechanical building of my CNC..

 

List of notable tags on LMR

Look at these LMR tags. And notice how easy it is to attract some major search engine attention towards important (or fun) subjects on LMR.

Go Buy a Bluetooth Audio Receiver!

I just bought a bluetooth audio receiver and you should too. It was about $40 (I won't add a link, there are many many different kinds out there).

It is absolute heaven to not be tied to our main house stereo with that damn headphone plug! I can zap audio from my iPod, mobile, any of the lappies and our main sit-down computer. For all that is holy in the world, go buy yourself one, you will not be sorry.

ADC and PWM

Hi guys,

I've finally found time to test te ADC and PWM capabillities of my picaxe microcontroller :)

Sorry for my bad english, but I'm a little bit tired ;)

 

EDIT:

added an SRF05 ultrasound sensor for some cool FX ;)

UNIO memory breakout board

A few weeks back I aquired some memory chips(samples rock). These are the special unio memory chips, essentually 1 wire for both input and output. As this is an 8 pin chip with only 3 of the pins being useful, I decided to try to make a simple breakout board with some small 5x5 hole pcb boards I grabbed from SF. These unio chips can be used with the20x2, 28x2 and 40x2 and the three pins are vcc, vss and I/O. The chip id is 11aa040(4k memory)

As recommended, I've added a small pullup resistor to the board. This is the results of...

A NXT robot playing tetris

A NXT robot playing tetris.

It uses a DSP board for the image processing and decision making, then uses different colour LEDs to indicate the NXT robot which key it should press.

First experiences of AvrUsb500 v2 programmer

Last week I got this avrUSB500v2 programmer kit from tuxgraphics.org. The kit has all the needed components except the ATMega8 chip. You have to purchase that separately. Here are the kit's components and ATMega8:

Note that FTDI smd-chip is conveniently already soldered to PCB.

Yellow Drum Machine gets kicked at Campus Party Europe

Hi.

I'm Michael, an innovator and concept making practitioner from Denmark.

I am about to launch myself into the world of robotics, and I am looking forward to blogging with you all.

In this video you can see how Frits kicks the Yellow Drum Machine at the Campus Party Europe 2010.

Drive system

Hi guys!

In my everlasting search for... well, basically anything interesting on the interweb, I've come across the RD02 drive system. This is a pretty powerfull motorcontroller, packaged with 2 encoded motors.

Some random features are:

Robot-SM advert

A small advert of Robot-SM that will be held on Sunday. You wil be able to watch it live here on LMR, if you haven't seen it yet the preparation is already available live on the front page.

Back Once Again

So after a long absence, I've decided to lurk around here a bit more recently.  I'd lost interest a bit - I blame the lack of a dedicated area for tinkering - having to clear up stuff at the end of the day, then lay it out again got a bit frustrating.  Plus, I got distracted by other things :-)

So anyway, I'm back now, relearning some things, doing a lot of reading, studying a maths course on the side, programming at work, and maybe just maybe I'll get a chance to make something....
