Customizing BoB with little modules

So I am sure all of you are now aware of who BoB is. Recently K12 and I have been talking about getting some BoB instructional videos up on YouTube to further make his construction easier and introduce him to non LMRians. Through this due process we have exchanged code, pictures of BoB and other extraneous things. K12 kindly gave me the Solidworks files for BoB and asked that I make some 'attachments' for him.

finally have the PCB's made up, and on the 30th november it took its first steps :)If you have any questions about this robot, leave a comment, or you can email me … Read more

Custom project board in progress...

Hi, I have a spare PICAXE 28x1 and L293D that I want to use for my first custom built circuit. But i have no clue what to do!!! The diagrams on the Picaxe website are so confusing and the ones in the manuals only show the pinouts. Can I just hook up 4.5 volts? Or do I need fancy shmancy support circuitry like capacitors and stuff? 

Thanks guys! 

UPDATE:

I have a diagram of the L293D and it is nice to have, but very confusing.

This came up with the need of having the arduino permanently installed on the robots, I´m tired of having to remove the arduino from one bot to the other, and then rewire everything, and then reupload the code everytime I have a new idea, or everytime I want to show the bot to someone.
I followed the ITP Physical Computing tutorial, and it works like a charm, no I want to try to upload code with the FTDI cable, and If I have success on this I can start making my custom Arduino boards. :D
