JKA has made an Java applet that takes serial output from any Microcontroller, and displays it in much better ways than the low-tech version I posted earlier. The … Read more
Just a quick tip on belt tracks, if you'd never did them before, and want to try :) Simple; one wheel in each side follows a motor, rest is free to turn. Motors can … Read more
Well, my 28x board is on its way and I have a good chassis to work with, so I will be building my first really cool robot soon. The problem I have is that the … Read more
(JKA is working on something more fancy than this, an applet for download)   If you are using Picaxe, I am sure you know, use, and appreciate the function … Read more
RC-servo to motor conversion   This is a smart little trick i had read about in the magazine "Elektor Electronics" a year ago. In 15 minutes you can turn your … Read more
This is Part II of How to build your first robot - tutorial. you can just take the cool navigation-code in here and have fun with it, or you can follow the whole … Read more
When I started out with electronics I didn't really know where to look for information. Most books I stumbled upon were much too heavy on the theory of electronics … Read more
On Picaxe: sound 1, (110,3) is NOT a good idea, you should allways write sound 1, (110,3) low 1 (you do not need line breaks, just write it as above)   Being used … Read more
If you are building a walking Robot, you will pull out your hair when trying to optimize the leg's movements. I had this idea; I had a digital camera, I strapped on … Read more
Please note: The info on this page is about a board. However, things can be different depending on which chips you stick into the sockets of that board, and how … Read more
If you are a newbee, you may only have learned that the Picaxe 28 pin Project Board has some inputs and outputs.. And you may have purchesed an SRF05 (that Picaxe … Read more
ER900TRS: An extremely smart little module. You just give it some volts, and a serial string, and it transmits it over air to another ER900TRS. This one can be … Read more
This is actually not a robot, sorry. But.. If you have an old laser-pointer, and are building robots:   Hook up the laser to the microcontroller. Now you can tuen … Read more
Schmartboard EZ review and tips on using it
I picked up the SchmartBoard EZ while working on a USB-Serial circuit using FTDI's FT232R. It's an SSOP package with 28 pins, so I ran over to Fry's to pick up … Read more
Analog in = digital in and out
This is just a quick arduino tip. Even though there are only 14 digital i/o pins, the arduino has more. Analog pins can also be used as digital. Analog pins 0-5 are … Read more
reads gcode from the serial line, moves stepper motors
I've been playing with the Adafruit Motor Shield v2 for some upcoming projects. I wrote a simple Gcode interpreter. With this you can write commands on the serial … Read more
