SRF08 ranger on Arduino

Mon, 04/15/2013 - 03:37
I've got a single SRF08 ranger running on the supplied 0xF8 address, but
I can't get it to work on the other addresses (I need several sensors).
I have verified the ranger to be addressed to 0xE8, but the ranger does
not reply to either the programmed address 0xE8, or the +4 address the
author uses for subsequent calls.

FTGH: Extra TurtleBot/Create power boards

Sun, 04/14/2013 - 18:14
I ordered a couple of the TurtleBot/Create adapter boards from BatchPCB and they threw in a handful more.
So I have I have 3 extra boards Free To Good Home(FTGH).
If you've got a Create and a netbook laying around and have been thinking about making a MockTurtleBot, this would be useful.

Let me know if you want one and I'll get it to you either at the next meeting or when we next bump into each other at

How about a Saitek X45 digital (USB) joy stick and throttle control? (again free)

Fri, 04/12/2013 - 09:50
These are pretty heavy duty devices, that I never ended up using. Its not
strictly a robotics thing but neither were the Legos really. Again free
(they're only worth $50 on ebay which is where I got this picture. But if
looking to fly something remotely these are pretty good quality. They
provide enough resistance that you really want to bolt them down to

Free Legos anyone?

Fri, 04/12/2013 - 02:21
I have a couple bins (those green ones from 10 years ago) of legos, a bunch of motors and sensors and two of the OLD style controllers. Free to anyone that wants them. jrg at toasterfish dot com and they're yours! (I'm moving so its out with the not-used-in-years stuff! :-)

3d printing

Thu, 04/11/2013 - 02:03
I have access to a Alfina printer, the resolution is .15 and I would be happy to print a couple of small parts for you, free if you could pick them up in SF or berkeley.

3D Printing Service

Wed, 04/10/2013 - 04:38
I have a small part I need made. (a 11mm wheel and pully for my Nanosumo
robot). Is there a 3D printing service anyone likes they would recommend?
It would be great to get around .1mm resolution if possible.

I don't know how many of you use this...

Maybe Camp or somebody knows,

How are the coordinates for the Robomagellan obtained and passed out?
Just by someone walking the course with a hand-held GPS?

Can we possibly do it with Google Earth? And distribute the coordinate
pairs on Email, CD, Thumb Drive or even a Floppy disk? (no transcription

Scavenger hunt?

Thu, 03/28/2013 - 20:47
Occasionally, while rummaging through the rubble pile that is my garage I find mystery components like those poorly pictured in the attachments. I think this is a quadrature optical encoder, but can't find any web reference to them. I also don't remember how I got them, but I think it might have been at a HBRC meeting.

Turtlebot and ROS Fans

Thu, 03/28/2013 - 08:01
IEEE will be publishing a series of weekly tutorials showing Evan
Ackerman getting his Turtlebot 2 up and running with ROS. Hopefully,
some of this will be useful to those with Turtlebot 1 and those of us
who are interested in ROS on other robots.


SIG Request

Thu, 03/28/2013 - 08:01
We've moved the SIG meeting to Hacker Dojo due to not being able to be
guaranteed room at Techshop. The feeling is that it's better to have a
consistent location than try to keep moving or either the location
and/or time.

However, to make this work, we need a pool of Hacker Dojo members to
