What's happening?


jesse I bought 5 ultrasonic transducers from Amazon for $6 shipped. They cam from china and took a couple of weeks to get here but at a little over a buck a piece, who can complain? I have't tested them yet though.

Joe Pardue I thought I sent a message to Tim last week, but no reply so either I didn't or used a wrong email or whatever. Anybody have a valid email address for Tim Klein?

Joe Pardue Are we going to meet in June?

If so I'd like to talk a little bit about the Arduino 101 series that I've been doing for Nuts&Volts that will finish out in December. I plan on starting a new series for 2015 that will be built partly around a novice friendly Arduino robot. We have sort of talked about something like this before, but I personally am finally in a position to really get into it so I'd like to gather whatever insights the group might have.

Billy Huddleston Yes, we're on for a meeting on the 15th.. I need to put it on the calendar. No, we don't have internet unless we use a mobile Access Point. (I can on my phone... I think Jay has one too.. ?? )

Joe Pardue And if we are going to meet, do we have access to the Internet there?

Billy Huddleston http://www.inmoov.fr/ Interesting! Looks like he uses servo's with a screw mechanism to convert them into linear actuators..

Michael Catlin Maybe this went into the wrong area (forums) so I'll repost it here.

Being relatively new to the Knoxville area, I don't know the best places to buy materials. In general, I am looking for square steel tubing, steel angle and extruded aluminum shapes. Is there a local metals yard that caters to the general public and offers offcuts and other selections? Nothing like taking a 20 foot long steel tube around the city in a Chevy S10. Also, are there any surplus suppliers with gears, couplings, tools, and electronic parts?

Thanks!

Billy Huddleston For metal, I use Specialty Metals & Supply Corp off of 2547 Scottish Pk, 37920 I've only gotten a few things from them. I order from http://www.speedymetals.com/ allot. I have no good source locally for gears, pulleys or couples. Ebay, mcmaster.com, sdp-si.com, qtcgears.com for those. I used oldham couplings for my Mill and cheap ebay alumn beam (helical) couplers for my router. Electronics, only places are RadioShack and Shields Electronics.

Jay Flanders I regret that I will not be able to attend the meeting tonight. I have developed sciatica. It's very painful.

Tim Klein Is the April 15 meeting on? Ben and I may try to come out. (Depends on how much homework he gets today.)

Tim Klein Well guys, the robotics madness is over and I'm starting to think about summer projects. A few of the high school robotics programmers, including Ben, are talking about exploring advanced robotics functions and AI, perhaps leading up to greater autonomy in their robots next year. 1) Are you planning on meeting over the summer, May to Aug? 2) Would any of you be interested in mentoring or following along with the project? 3) Does anyone have any great suggestions for a solid robot base that could support python and vision?

Tim Klein
Tim Klein As discussed in the meeting Tuesday, I think we'll focus on code, without simulation. However I thought some of you might be interested in this find. https://aseba.wikidot.com/en:thymioexplorer#toc11

Tim Klein
Tim Klein The kids I've been talking to are thinking entirely about software. That's why I think the simulation option might be good -- no distractions fighting with the real world.

jesse
jesse It really depends on what you want to do with it. You may want to play with a Raspberry Pi with a lower level board like an Arduino, MSP430, or STM32 for interrupt/encoder processing.
