Post UPEW - Rick / Tentacle - LA robotics supply stores?

The UPEW was so cool!

I've been thinking a lot about the Tentacle that Rick showed. I wish I had taken some pictures of it. I live in Spokane, Washington but am visiting Los Angeles for a few weeks. I'd like to take some time to hit some of the hardware and junk dealers that are not available in Spokane. (I know were Fry's is)

Does Rick lurk in this forum or does anyone know his email or a web site where he has the tentacle documented?

... and if you know of some great places in Los Angeles for 'parts' of any kind let me know. Electronic stores, electronic surplus, hobby stores etc... ???

Thanks! - jeffa

    Hi Jeff,

    Do you have a Parallax 2010 catalog? If yes, take a look at page 75. It features Rick's RC/autonomous submarine, as it existed about a year ago. Sounds like he's made some changes since then!

    Rick includes his personal website in the catalog: www.remotelyinteresting.com.

    If your in the Riverside area east of Los Angeles we have Electronics Warehouse http://www.electronicswarehouse.net/ they have a lot of good stuff. Both new and a surplus store also.

    I'm not that bright and I can prove it.
    At the end of the day, it gets dark.

    All Electronics is very popular; it's in Van Nuys not far from the 405/101 junction and open seven days a week (can't beat that). In addition to electronic components, All carries a wide variety of surplus materials and is a great shopping spot for prop builders.

    :-) They need bigger shopping baskets at All Electronics! Catalouges are cool, but it's nice to touch and feel while you're looking. I scored some nice wiring harnesses, some push buttons with rubber covers and other miscelaneous stuff. For two bucks I got a 'Saw' message recorder that will be a great 'gag' gift for my employees when I get home.

    I'm also looking for a BBIIGG hobby shop. Where I might buy some servos, but more importantly an assortment of control horns and other hardware to attach to servos. Store in LA during visit would be cool otherwise anyone have a neat URL for an online source?

    I'm also looking for some control cable to attempt to make the Tentacle that Rick showed.

    Happy fourth of July to everyone!

    Hobbytown USA is nation wide and there are a couple of stores in CA.

    http://www.hobbytown.com/

    search by ZIP Code.

    I use Hobby Lobby International, only because they are local in Nashville. I used their Pushrod systems on a couple of animitronic projects.

    http://www.hobby-lobby.com/hardware_154_ctg.htm

    They ship world wide.

    That may be a little heavy for standard hobby servos. Most hobby "Push-Pull" lines are wire through a plastic sleeve, not the coiled wire of a brake cable. And the hobby stuff is much thinner, allowing more cables to fit in a smaller area. All depends on what kind of loads and bends are involved.

    Hey Jim,

    Thank you, would you know a link for this smaller cable?

    @hover1, There's lots of stuff in that link.

    Can you please post a link or part numbers for the *specific* items that
    you successfully use with your servos? What servos do you use?

    Thanks,

    Kinda getting off topic for Propeller topic. Should be moved to the Sandbox.

    Steve,

    I started out using this product:

    http://www.hobby-lobby.com/best_complete_throttle_pushrod_1019_prd1.htm?pSearchQueryId=732789

    The I just started buying bulk because I used so much:

    http://www.hobby-lobby.com/20_feet_flex_cable_pushrod_18444_prd1.htm?pSearchQueryId=732789

    Of course I have a couple hundred of all the connectors for the ends. Depends on the application, but pretty much all RC stuff.

    I used these servos:

    http://www.hobby-lobby.com/jr_ds8711_ultra_torque_digital_servo_rc_servos_81199_prd1.htm?pSearchQueryId=732797

    only because I could get the locally in Nashville. Since I'm moving to the Northeast, I will be getting my servos from ServoCity:

    http://www.servocity.com/

    since I will have to pay shipping anyway, and ServoCity has better servos for robotics projects.

    Jim

    Those links are very helpful !!

    That servo is a big one at 350 oz/in.
    This could be very expensive for actuators depending on the load.
    Is there anything left over at the end of a wire for the target load?
    How would you calculate the torque requirements for different loads?
    I hear a book or a thick user guide coming [noparse]:)[/noparse]

    Sure, but this was a big topic at UPEW -- hence the topic and title.
    I would have totally missed this if it was posted anywhere else.

    Steve,

    Yes the servo was overkill, but since I'm moving, I don't want to make a 1800 mile round trip service call to replace a servo[noparse]:)[/noparse]

    Not sure what you mean by "Is there anything left over at the end of a wire for the target load". By using bulk stock, I cut everything to what I need as far as travel needed.

    As far as "How would you calculate the torque requirements for different loads", I wing it. The different artists that put together these projects have no conception of friction, so they just make their armatures as they like. I have to fit a servo to fit the need. I am getting further into creating more of the basic designs to incorporate a better armature system. I have left that company and will now be doing consulting work for them, so I will have·more input into the design of future products.

    Why is it that your company will not listen to you untill you have left?

    Jim

    PS Just so you know. I have just 2 animitronics projects under my belt. I am no expert. But I do a lot of R/C.

    That's 2 more animitronics projects than me smile.gif I'm a newbie in that area and certainly appreciate your guidance.
