Speed Simulation

I wrote up a simple Javascript web application to simulate the speed of your robot compared to other well known objects ( a bike, a car, etc.). There is also a football field in the background so you can see your robot's speed in relation to a football field.
Right now the simulation only supports whole numbers and only only operates in the feet per second resolution. I will add on support for meters per second later.

Also I am 75% done with the simulation portion for slow speeds in the inches per second scale. That part has a yardstick in the background. That should be ready in a few days.
Heres the link to the simulation , just enter the speed in feet per second in the text box above

New Layout for Narobo.com

Just finished the new and improved layout of my main website - Narobo.com
Put in some javascript and also put up the Narobo Logo.

Roboduino on MAKE !

The Roboduino was featured on MAKE: Blog.
http://blog.makezine.com/archive/2009/01/roboduino.html

Been busy with the Roboduino lately, so not much more updates.

I am working on a simulation to see relative speed in relation to a well know object in the background(ruler, football field, etc.) . It will be useful when you are trying to figure out relatively how fast an object should be going . I would also add other moving objects that would move alongside the object ( a car, a person running , bicycle, etc.). I plan to add text boxes to enter in speed and also checkboxes to select which objects would show up on screen.

Implementing RF Modules Tutorial

I finally wrote a tutorial on using those pesky RF link modules. When I first started out using the RF modules there were only two tutorials available and they weren't so clear. After a month of struggling with the RF , I managed to get it to work. I had some spare time on my hands so I wrote up a giant tutorial on using the RF modules - its filled with code, schematics, and helpful tips.

The Roboduino is finally on sale!!!

Its $40 for a kit and $55 for an assembled version

More info and sales information here:

http://curiousinventor.com/kits/roboduino

Features / Specs:
* 100% Compatible with Arduino software.
* Power buses along side pwm and analog pins easily accept standard servo and sensor connectors.
* Powered can be supplied from USB, barrel plug or 3-pin male header. You'll need a suitable power supply when driving multiple servos.
* dedicated UART 3-pin male header
* 6 PWM outputs with neighboring unregulated power pins
* 6 analog pins
* 14 digital pins
* Reverse polarity protection for board circuitry (not for unregulated power pins)
* Optional I2C pull-up resistor locations

Looking for Beta Testers for the Roboduino

I'm currently looking for some beta testers for the Roboduino
Roboduino Specs: http://erobots.blogspot.com/2008/11/new-robot-product-roboduino.html

Beta testers get a special discount on the Roboduino - $30 for the Roboduino kit ( thats 25% off of the retail price) and $50 for assembled board
(no discounts on an assembled Roboduino)


Beta testers are expected to use the Roboduino on robots or some electronics. Testers are expected to take pictures of what they used it on and also must report all malfunctions, any errors, etc.

If you are interested please contact me through email : airman00 at gmail.com . Include how you plan to use the Roboduino, any robotics/electronics experience you have , and if you want the kit version or the assembled version. Space is limited and I will be picking the beta testers I think are best for the job.

Thanks
,Eric

EDIT: No more spots left for beta testers. It all got filled up in a couple of hours.
Expect the Roboduino to be on sale in late December

First Roboduino Assembled!

The first Roboduino has been assembled and brought to life!!!

I tested out everything there - UART, PWM, status LEDs, etc. and all is working perfectly!!!
