DorkbotPDX people doing strange things with electricity

That would explain a lot wouldnt it?

I am regularly sending ordinary people to look a the application sections of the datasheets for several electronic parts if they want to know how a part should be used. As I was laying out the motor boards for the weekends workshop I came across the following in the datasheet for the l239d clone that Texas Intruments puts out.

Can you tell where the chip begins and the diagram ends? Can you tell that the diodes are included in the chip or would you add them to your parts count.?

Introduction

This is a first take on using the Benito board to create an open source USB to Serial converter.

Hey all,

Blue tooth to classic handsets.

I'd like to take a classic Rotory dial phone make it dial and call and ring the old ringer make real phone calls. a cell phone communicator on a classic phone

Analog synths (homebrew portables mainly)

Old classic electronics gadgets working with newer things

Making musical instruments.

I'm interested in helping drive the technicals into the steam punk movement. Real steam, real workings inside the look. I tinker the magic kinda idea.

SPI4 is a MyUSB based firmware for the at90usb family of processors.

Missing Links.

One of the joys of the Arduino Cult Induction Sessions is that mistakes and omissions are generally caught on the spot and there is no lag between the steps we forgot to include an the instructions and the person who's board isn't working.

This is something to chew on while I put together some bigger pieces.

I've placed a brief Dorkboard assembly tutorial online. It's my first attempt at a photo documented circuit tutorial, so feedback is always welcome.

I'm sure there are nuances/subtleties that I've missed...please report them and make the page better!

This group got further along than any induction so far. I was really happy and thank every one who came out. I have a couple of things here as a follow up that might be helpfull and if you leave comments or email me I can follow up here as well.

First here is a map of the dorkboard pins using the arduino pin numbering system.

Also here is the .inf file which makes the Benito use the built in windows drivers.
