Let's Make Robots!

Stuff to do while waiting for parts.

I ordered my parts for my first robot (from the start here section) and not wanting to sit idle I have been finding and doing projects from instructables.com that involve soldering or other skills that I believe may be transferable to robotics.  Any other suggestions?  The hard part is finding parts locally, Radio Shack just doesn't carry a lot of electronic components like they used to.

books with robots

where can i find robot books???suggest me some sites!!!

Homemade digital compass

Some time ago OddBot posted this circuit for a homemade digital compass based on hall effect sensors:

Unfortunately CircuitBurn couldn't make it work. However I'm inclined to try again. A cheap DIY compass would be great.

So if anyone has ANY idea as to how this could be achieved let's hear it. It could be an improvement on OddBot's circuits or something completely different and wacky :D

Calibration problems with a Maxibotics XL-EZ4

Ok, here's the deal. Today, I got my fantastically awesome order from sparkfun. It included:

The Maxibotics XL-EZ4 Rangefinder

The JPEG Compression Camera

I managed to soder some wires to three pins of the EZ4 without burning the house down. I got GND, +V, and pin 2 (Digital signal)

PIR to PICAXE interfacing

Hi everyone. I am thinking of making a robot which uses 3 PIR sensors RAPIDONLINE 61-1516  to detect and track objects emitting thermal energy.Do you think using a 9V battery this would
work?in terms of power consumption and stuff like,considering i would be using 3 of these PIRs and other sensors like microphone,buzzer etc.

How To Add An Avatar

Hi Guys,

 

I'm brand new here and I've searched the site and can't figure out how to post an avatar....any suggestions on where I may look?  I didn't see it under my account settings, nor did it come up when I searched the forums.  Hmmmm...

 

Thanks!

Hello and My New Arduino Robot Project

Hi Guys,

This is my first post here although I have been lurking for a few weeks now. I am brand new to the world of robots and Arduino. I bought my first Arduino in September and I'm just starting my first robot! My robot's name is Herbert...named after H.G. Wells and kind of an homage to Star Trek....

I plan to have Herbert be a long term learning project. I'm starting with simple motor control and moving up and onward from there. Here is my first video documenting my learning about Arduino motor control using transistor circuits:
