[NSRCA-discussion] Looking for a Proline Tx with Chidgey sticks

Tue Mar 14 17:52:31 AKST 2006

BlankEmory,
These guys are out of control. Well, at least I know Ed is and I suspect
that Gordon is too although I have not met him personally. Don't try this at
home... OK, if you must know, they're building transmitters with custom
encoder modules. Basically a "computer" transmitter built out of the old
(high-quality - not cheap plastic) guts combined with a micro-controller
based encoder. Lots of fun!!! I guess I have to build one now too. Check out
Gordon's site - lots of cool stuff: www.mstar2k.com .

  Alright. My interest is peaked, but I have no clue what you guys are doing
to these Proline transmitters. For those of us that may be electronically
challenged, what modifications are you floks making???

  Thanks, Emory

    Ed,

    6.8K SIPs will work fine. I used 10K but these are just pull up
resistors so 6.8K will work fine. The source code is available, I have been
sending it out on a request basis but I will post it on the web site soon.
Regarding the receiver; the MC13111 is indeed discontinued but I have 250 of
these parts in stock. I did a life time buy as they were going out of
production. This is a great part, a one chip synthesized receiver chip,
perfect for a RC receiver.
    I too build a heathkit RC system with my dad years a go, indeed the good
old days! Growing up with single channel escapement systems and reeds is
what captured by interest in electronics, remember the Digitrio systems? I
have all the documentation and a complete system.

    Hi Gordon:
    I've been a lurker on the MP8K list for a while and finally decided to
build the mstar 2K yesterday. I'm just about done except I have to get
replacements for the resistor networks, having 8 pin SIPs instead of 9 pin -
whoops! Those are 6.8K, correct?  Other than that, I haven't run into any
snags yet, but I will definitely take you up on your kind offer to assist if
needed.

    I thought I saw something about source becoming available for the MP8K,
but I didn't realize the mstar 2K would be open source - very interesting.
Looking forward to the upgrade as well.  Re. the PulseStar receiver, that
looked really interesting too.  Did the MC13111 really get discontinued?
It's a shame if so.  I have to say, the projects you have done are really
admirable.  It's great to see this kind of project still available these
days.  I built a Heathkit GD-19 when I was a kid, when it was still fairly
common for hobbyists to build their own stuff, including servo kits from
World Engines etc.  That Heathkit still works, KPS-9 servos and all and I
flew with it right up until the mid 80's, though I did eventually replace
the receiver with an Ace Silver 7.  The good old days...

    Thanks
    Ed

      Ed,

      Thanks for the interest in my Encoder. The Proline transmitters are
getting hard to find, the last one I picked up was at Northwest Model Expo.
I'm sure you are aware of my web site, www.mstar2k.com, you can find all the
technical data on this site. I'm happy to help you with this project.
Electronics is my second hobby and my projects open to the public through my
web site. I would estimate about 50 to 70 systems have been built to date.
This is the only "open source" design available.
      I will be designing a next generation encoder using the PIC18F8722.
This encoder will be smaller but it will be next fall before it is complete.
This version will have digital or analog trim options as well as other
upgrades. Again, thanks for your interest and good luck with your project.

      --Gordon

      BTW; I'm a licensed Radio Amateur (KG7YU) and all my home built
electronics are on the HAM bands.

      I'm looking to buy a ProLine 2 stick transmitter for an update project
I'm doing.  I'm building a Gordon Anderson Microstar 2000 encoder and was
originally going to fit it into a Kraft Tx, but the fit is fairly tight and
the open Gimbal Kraft sticks just aren't as good as the Chidgey sticks were.
The ProLine was taller and everything ought to fit better.  I can make the
Kraft conversion work, but the ProLine approach is much more appealing.
Anyone know of a source for one?  Tired of trolling eBay...

      Thanks

      Ed
