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

Tue Mar 14 17:33:23 AKST 2006

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
