Some really great shots, thank you

I don't know if this is necessary but just in case some haven't found the photos thru Facebook or at RC Canada here's the link to my album on Flickr.

General Discussion / Re: Field Charging Station

I get what you are saying.

The 12 volt idea is simple and efficient (if the main goal is to provide power suitable for LiPo charging), as there is no up and down conversion to/from different voltages and ac/dc involved. Right now, folks are either carrying lead acid batteries around, charging under the hood (remember why it is called a "firewall"?), inside the car (remember Dave's van fire?) or lugging generators to the field. We could still have basically the current setup whereby the weather station is powered by the big battery, topped up by the solar cell and by generator whenever one is
available, with some simple changes:
1. Add additional solar cells to boost up capacity, as you suggest
2. Add the simple "plug board" to access 12 vdc for chargers. We could even set up a small panel with, say, Power Pole connectors and/or other commonly used ones.

This would be simple, cheap, easy and quick to do, wouldn't it?

I like their approach with will definitely handle a few chargers at once. I would like to see a more universal and maybe a little less accident prone method. I would use two or more 100 watt solar panels feeding through a charge controller to a couple heavy duty batteriess such as deep cycle marine batteries.  Connect these batteries in parallel to feed a 1000 watt inverter.  Connect this to the whole club house AC system through a voltage source selector switch (generator/hydro switch). This way we could use the solar system for normal flying or switch to the generator input for all our large events which require more power to run things such as coffe makers etc.


Just an opinion...

Wouldn't it be nice to have charging station at our field?

Well, here is a nifty setup that the Cornwall club has. It was created by a former member (recently deceased). Pictures are attached.

The solar panel is mounted on the roof of the clubhouse. The charging station holds one or more large lead acid batteries. Like some other organizations or individuals have done, they acquired these from Bell as that company replaced them with Li-Ion technology. So, they are really heavy duty batteries. The appropriate electronics then feed 12 volts to a rather innovative arrangement up top. Two bare wires run behind the vertical backboard, one is positive, the other is ground. The drilled holes allow you to simply clip onto the pair at any available opening. Note the ceramic floor tiles in place as a fire protection.

This is a very nice setup. They operate year round and have not had any need to supply generator power to supplant the solar plus battery combination.

Something for us to consider?

I have finished implementing and testing the ZERO THROTTLE ARMING program for my Graupner MZ-24. This program will work with most radios which allow LOGICAL SWITCH programming under the FUNCTION menu.  I haven’t created a step by step write up yet, but I will E-Mail it when it is finished to anyone who is interested. My address is wilf.hill47@gmail.com.


If I finish it today, I will bring copies to the meeting tonight as well as demonstrate.

General Discussion / Remote Weather and Video Stations
« Last post by Deerslayer on August 13, 2018, 07:17:08 AM »
We are fortunate to have a Member, Dave Fasken, a Ham operator and electronics hobbyist in our club, who took it upon himself to fabricate our weather station at the field. This is based upon an amateur radio link to a server system on the Internet; an licensed amateur radio operator is required to be its owner/sponsor. Dave, Wilf, Herman and perhaps some other Members are such.

Over several years, some of us have wished for, and discussed, the possibility of obtaining something similar for still or video coverage of part of our field. Apart from the anticipated expense, there is the issue of how it could be done.

Here is a bit of information which I picked up at the Cornwall Fun Fly this past weekend.

A fellow flyer brought out one of his weather stations to demonstrate. There are a couple of clubs in the Ottawa area that have installed them. The system consists of the measuring instruments, a small solar panel, a small lead acid battery and the associated Arduino-based electronics. This was mounted on a piece of conduit - very compact!

The communications method is via the cellular network. You dial up the number and you get a test message with weather details. Pretty slick! He monitors his remote stations over the cellular network. The cost of this setup is $520 per year, which is affordable to some RC clubs, especially where their membership may have long driving distances. He retains ownership, looks after replacing the battery, if needed, and handles any technical issues. The predominant cost is for the cellular account.
 
So, "What about video?". The answer is forthcoming, but first you may find his information to be of interest:

Video?

He has done that as an experiment. The issue is cost of the "smartphone" connection, as opposed to the bare-bones texting capability of his weather station. Even if you only do still shots, perhaps updated once or twice per minute, you still need this level of service. He priced out his complete package at approximately $1700 per year - well above what would be practical for an organization such as KRCM.

Now, there may be other approaches, such as through the amateur radio community. Or, if a site put in an Internet link, along with associated support equipment (battery, inverted, solar panel, etc.), something could be set up. It could still be something worth investigating, of someone has the inclination.

A few years ago, Mike Lucas of Zycom Technology here in Kingston offered to look into this, but it was never followed up on. Mike's son was a KRCM Member and I have known and dealt with Mike professionally beginning some 20+ years ago. He is the co-founder of that company.

KRCM Training Course, Flight Safety & Training Nights / Graupner Throttle cut revisited
« Last post by Wilf on August 11, 2018, 09:51:51 AM »
I think I have a solution for the zero throttle position problem. It requires 2 logic “AND” Functions and an “OR” function as a latch. The logic works so that the throttle stick must be at the idle position before the throttle arm switch is enabled.


I am still working at programming it into my Graupner, but will keep you posted as I get it working.
