I am now thinking of making something like this, only a bit bigger.

Finaly it's Done! - SkarkFun Graphics LCD Serial + Backpack Display

PROBLEM SOLVED

Woohoo, i can now control the display via 28x2, or via direct interface with visual basic applications which i create :D

 






 

Xbee Live Conference

Call for conference guests

Who is interested in the upcoming Skype Conference on the advanced features of Xbees? The conference will be broadcast as a special live episode of the video (help-) show.

We are looking for a suitable and practical time slot. Hopefully some time this weekend. Can I hear some suggestions?

GRemote

This is my first attempt to make a custom remote controller, and also my first customized Arduino.
After seeing this post made by ObbBot I wanted to try to make one myself.

I figured that if I purchase one remote controller it would be cheaper than buying two of these and paying shipment to Portugal.

So, ripping the guts from a game remote controller I get two joysticks, a couple of buttons, two nice motors and one small lcd.

Thanks to the naming genius of GroG... I now proclame thee Walter!   ***Major Update 11.16.08*** First test worked perfectly! Even with bad code. The motors came … Read more

can i still add a laser, speaker, led?

in my robot SC-QR-1 i have allready used all 8 servo-ports.

but can i still ad a laser(to see where it looks), a speaker(for it to call hor help or showing some sound-emotions..   etc.) and some leds(like a red to show power, white/bright to help my "primary-back-mounted-not-night-vision-spy-camera") 

and if yes would the servos disturb the lasers, speaker and leds?

and i was also thinking, stuff like the sharp ir sensors have ir leds in them, could i attach an led or laser to those pins??

 

please reply!! :D

Using Frisls "Clean navigation" with a Sharp GP2D120 IR Sensor?

Greetings from Finland.

1) Is it possible to use frisls "clean navigation"- code with a sharp GP2D120 IR sensor? I know after looking at his code that the distanse readings are backwards (on a sharp closer distanses are greater), but if I changed them would I be able to use his brilliant code as a base? 

2) what is the differenses on SRF05 and sharp GP2D120 other than one is a
ultra sonic and the other is a infrared.Idon't meen number of conections but speed as in using themto almost constantly return the range
