Status: offline 		Edgar,

It is actually very simple to set up. Yes you will need a link Vario, and the speed sensor from Wea which has a pitiot and a circuit to convert the 2 pressure sensors to a voltage. (I am actually using an Eagle Tree pitot tube and a Gasper Xcoiy Sensor circuit, which seems to work.)

The pitot connects to the circuit via 2 silicon tubes. The sensor circuit connects to the Link vario with a standard servo connection, and the link Vario connects to the Rx using Weas special 2 pin cable. The Vario is powered seperatly (from any servo lead.). The Link vario also has a slot to direct connect the GPS unit to it using a ribbon cable.

I use the latest version of Giga-control, along with the firm ware, and the system just works, with no need to set any parameters up. (I don't know how 2.33 would work. It probably will.) Giga-control does have the ability to announce various thing including airspeeds etc, but with no voice file, it is a bit useless.

I have flown it with a lap top attached to the Tx, and the Big Display function (Giga 2.59) can display live airspeed, rate of climb, and altitude.. That's pretty cool.

Roger

Hi Ross,

dont know why that did not work for you. When I click on the links in my post, the download starts... Maybe you can right-click and select "save traget as..."  ? I only noticed that this forum seems to rename the file as the original name which Olaf (developper) gave it (and which I used to upload) is replaced by a non-self-speaking numbercode...

You can send me a PM with your email, I will mail it as .APK directly to you...

BTW, can you see the screenshot I attached in my post ?



best regards

Tom

Thanks I finally managed to download it.
The program seems to work well, I connected to my MX24S and to the MC32 without too much difficulty.
(Much easier than the very early beta I received in March this year).
Now can we please have an English language version, for the names of the data and for the help file.

Best wishes
Ross

Hi Ross,

fine that it finally worked for you. The "big jump" regarding the ease of connecting via Bluetooth was introduced with Beta v14. Even with the Beta v13 released just a few days ago, I had intensive problems to connect with my Motorola Defy+

What Android device are you using ? OS version ?

Regarding the language: I guess most of then are self-explainatory, if not, I can post a translation for you.


best regards

Tom

Status: online 		an update for those who are interested, the mystery of the glitching gyro continues. Summary - in my F-86 at certain engine rpm, both gyros in a 12-22 kick the servos or make them twitch. Happens for both my 12-22 rx. Happens when rx un-mounted from model and held in hand.

Today I tried running the engine by controlling it from a servo tester, while using my spare 12-22 with its own battery and a couple of servos so that it is completely electrically separated from all the systems and wiring in the aircraft. Even hand holding the rx it still kicked the servos. So that has pretty much proved that it is sound waves, not electrical "noise" that is the cause of the problem, it must be a jolly high frequency and at certain rpm just the right harmonic of the MEMS gyro frequency, perhaps helped by the acoustic properties inside of this particular tubular fibreglass fuselage, as the gyros are ok if the rx is held next to the engine but outside the model, but as soon as it is held inside the model the problem appears. All info provided to Wea to help them diagnose the problem, but now I can't see a way to cure this, how do you prevent some unknown sound frequency which may well be ultrasonic, from getting to the rx?

I will try next with an ACT Fuzzy gyro mounted elsewhere in the model and see if that suffers or not.

Status: offline 		I've not used the WEA gyro systems but perhaps can help. The exact same issues occur with like Futaba 401,501 or anything similar, qwark etc in helicopters. The resolution there is a rubber mount between the gyro and the frame/fuse. It takes some doing to come up with your own resolution, how hard, how soft of rubber/sponge to make it work right. SOmetimes it's a rubber, then metal, then another rubber to get it right. Sometimes hard almost solid and sometimes others free to slop around.
I don't know if this is of any assistance but just thought I'd mention it as I've 'been there' with helicopters jittering at different mechanical rpm's

Status: offline 		But Harry has determined that it is likely due to acoustic energy resonating inside the fuselage. Therefore mounting springiness/dampening cures will do nothing. Harry, you may have to hang the receiver on a sling carried outside the fuselage!!! OH MY!

Status: offline 		Back 30+ years ago, I had a heliboy that would fly one time and not the next. I was only secure in hover as it could become radial out of nowhere for no reason. I tied the heli to a test stand and put an oscilloscope on my receiver (a Royal by SidGates) and found that at certain rpm, there were giant electrical spikes in the system. There was no electrical connection to the frame of the heli, just a bunch of aluminum parts. It had a tuned pipe that was connected to the engine header by a silicon sleeve. What we found was that the pipe (that was mechanically connected to the boom on the output end) would touch the header inside that sleeve and giant electrical pulses were being sent to the receiver. The engine was mechanically tied to the same frame that the boom was tied to which was bolted to the muffler end, a giant loop if you will. I pulled the muffler out 1/2" from the header and fixed the problem. So indeed, you holding the receiver may be buffering some electrical noise or vibration getting to the receiver/gyro. You might try holding the rx/gy 90 degrees in roll or yaw to the engine and see if it changes also. Since you can hold it in the model, not touching anything and it acts up but away a short distance sounds more like an electrical interference (my heli) type issue.
If you have the option, I'd put a scope on the signal lead of one of those servos and see what's traveling along with the normal signal as you go from good to bad. It might lead you to the cause.

I am not an expert on "sound" but would a styrofoam box around the receiver protect it from sound waves? I use a stryo box sometimes for the receiver for just crash protection.

Status: online 		just for interest i googled acoustic intereference mems gyro and discovered the early ones (all mems, not just weatronic gyros) were prone to it so the vibration frequency of the mems gyros was increased so they are not prone to the acoustic range likely to occur in consumer units e.g. phones etc. I bet they didn't account for the frequencies a fast turning model turbine can produce! So mems gyros can be hit by sound intereference and since that's the only thing left to account for the interference I get, I am satisfied the cause has been found.

Now, can anyone explain how to use the external gyro inputs on the 12-22? I hooked up my spare ACT gyro in the normal way and it works fine but I thought it would be nice to try it via the 12-22 software.
I connected Rx servo 1 to the gyro input and the gyro output to Rx ext gyro 1 input. Go to servo 2, assign it to the same aileron channel as servo 1, and enable ext gyro 1 from the drop down box. The servo swings off centre and hunts slightly. It responds to the aileron stick and to the gyro. But it's no use if it goes off centre and hunts. What am I doing wrong?

Harry

Status: online 		Weatronic has accepted that we have gone as far as we can investigating the gyro glitch, and put it down to acoustic interference. They will bear it in mind for future designs. It must be very rare, but MEMS gyros are known to be affected by sound, I guess I have just hit a very rare combination of engine and fuselage structure that is just right for the necessary frequency to interfere with the gyro.

Nobody got experience of using a gyro via the ext.gyro sockets on a 12-22?

Status: offline 		Hi Harry,
I have some experience with acoustical feedback. For a stereo sound system the feedback of the sound system can actually cause unwanted effects that will alter the sound quality. If you have the stereo in the same room as the speakers, resonance within the housing of the player / amplifier or the surface on which the system is standing can cause unwanted effects. My brother in law used visco elastic foam (like in the Tempurpedic mattresses) to isolate the effects and all of the sudden the music being played was a lot more crisp and richer in sound. I suggest you get some of that foam (maybe a sample from a mattress store) and either use it to put around the receiver, or actually place it in the receiver on top of the gyros and against the housing. I think the foam is non conductive and should have no effects on the circuit board. Just a thought to put out there worth trying.

Yes Harry, there is once again a radio silence at Weatronic, no reaction more from Jens.
Perhaps preoccupied with the exhibition with workshop in Friedrichshafen on 3 november?

You're right, but i think it is not normative for all German companies, and yes it irritates enormously.
