Cables for DorkbotPDX Programmers (updated for Duce).

In the course of the Arduino Cult Induction series and the group purchases, I have evolved several versions of the DorkbotPDX programmer and released them into the wild. Unfortunately the pinouts for the programming cable have evolved with the programmers so the cables are unique to each. With the Duce, the pinout is based on a standard (the stk500) and will not change. .

Here is a quick guide to cables for the DorkbotPDX programming boards for the rbba and the dorkboard.

midi on the avr

I've posted some of the code I've been using for midi on an avr chip [atmega16]. It should work on other avr chips with little or no modification. I'd love it if others would test it out and and contribute.

I've included a little bit of info and some example code here: http://x37v.info/projects/microcontroller/avr-midi/

Remote contol

I have been working on the chassis of a larger robot design just for fun, and I have run into a bit of a problem. Can anyone think of a simple (and cheap) way for me to take 12vdc in and output 5-7v to control pins. The forward/reverse and right/left are controlled by a joystick right now. So in the resting position the voltage on the control pins is ~6v full forward is about ~6.95v and full reverse is ~5.05v. The same holds true for right and left. I want to do this using a rc car controller.

Arduino Midi Anyone?

I'm new to Arduino (and this group) and would like to create a Midi controller using this interesting new circuitry. Any information about what I might want to purchase to get started would be just grand. My goal is to create a Midi Concertina Accordion controller much like this one: http://home.stny.rr.com/peverett/gadget.html , only using Arduino. If successful, I imagine a small Midi band meeting late evening upstairs at the Lucky Lab in Multnomah Village. I too work with electron microscopes . . . must be something in the water here in the NW? Cheers, BD


Here I am.

Hello Everybody! I'm a System Admin at a local ISP/Webhost/VOIP provider. Thats just my day job though. Most of the time I am downstairs in my little shop poking/breaking/fixing/making things. I'm somewhat new to the whole robotics arena. I am quite interested in the physical computing platform. Drop me a line.

Meeting :: Tomorrow 5/26 7pm at NW Lucky Lab

Arduino: Just getting started...

Background: Played with basic stamp in the past. Let the magic smoke out of alot of electronic widgets (including a 3 million dollar electron microscope... but that was my job sorta) Went to the indoctrination, parts 1 and 2. I now have a nice arduino (bare bones) that I've been fiddling with, thinking about....

I am a Ph.D student in Systems Science. I live and teach in Portland Metro.
