With Open Tx you can do most things

[Konrad]

Yes, it is a dead band and hysteresis issues. A wide dead band can reduce the noise with the corresponding drop in performance. Noise in of itself is not an indication of issues with the digital servo set up. Unlike analog servos where the duty cycle of the amp output (transistors) is not rated for close to constant use (Buzzing).

In this application some servos are always working against the weight of servos suspended from the output shafts. This will take power (buzzing/singing) to hold position.


I was sorry to read of Ove Joensen drowning a year or so after his feat in the full size boat..

Yes, I'm following you.

What I found interesting was that running an FrSky receiver capable of a 'high precision' PWM signal removed the buzzing without any need to adjust the deadband of the servo. I think that must mean that the high precision signal does not vary outside the deadband of the servo. At least, it did not with the MKS and KST servos I tried.

In SBUS mode, the G-RX8 puts out such a high precision signal on channels 1-6. Apparently, some or perhaps all of the Archer receivers put out such a signal all the time. I haven't tested that.

I recall reading reports of heating associated with buzzing digital servos. However, a couple of years on, I don't remember if I encountered heating.

Andrias - Thank you so much for these details! I still studying the mechanics of what he had made. Very impressive! Please tell him we are all loving what he has made, it is a real work of art and a true labor of love and respect.

I love the photos of your club site also! Wow. Such an amazing place you live. I'm still looking forward to some photos of the slope sites there. It may be remote, but wow it is amazing.

Thank you
I show him this.

Wow- everyone here at Aloft is impressed.

With OpenTX I think he could automate the mixes and be able to point the sticks in the direction he would like to go. But I sort of like his radio setup..

We have programmed one of these automate. But it was not the right cup of tea for my friend.
One has to work a little this is too easy ?

 

[HENNY]

What craft is this program used on.

For this one. was mostly for trying but the but is manual rowing now with tx sticks.
if you go further back in the thread they are more pictures and vidio of it.

 

[Wayne]

I agree that moving the sticks is pretty darn cool, but if feeling lazy one could hit a switch and change the mixing over to point and shoot mixing. With global variables you could even use a side slider to adjust the speed of the rowing action, or just make it so the more you move the stick in that direction, the quicker it tries to row? Kind of endless options when you think about it.

 

[Andrias]

Thanks for the input. The things he has been talking about are.
1.To install gyro in the arm servos. When the boat rolls side to side, the oars are just at the same deep in the water on both side, at least not become loose from the lake.
2. Made one mode. That he stops to row the boat and drives the oars up from the lake and the boat lays still.
3. And to build a servo in the head so it can go from side to side.

Then we'll see what happens

Now I have made a video with text so her it is.
Birgir passed away last year 89 years old.

So wonderful. A unique accomplisnment that brings delight and admiration.

as a former competitive rower , I am impressed by this model, and the realism of the rowing action imparted by the person at the Tx sticks. Hats off !!!

 

[Andrias]

Andrew C. and Sokol thank you very much.

Rowing is our national sport, the same type of boat but with 6 rowers to 10

Sorry to hear the news of Birgir passing. Sounded like he was a wonderful gift to your local community as well as to the community around the globe.

Thanks again for sharing this!

just seeing this post now. Amazing work. And love The creativity

This is an amazing piece of work. talk about "thnking outside the box"! I do not want to even imagine how long it took this gentleman to make to adjustments and fine tune the mechanism. I know that it can be exceedingly frustrating. I bow to his patience. I am sure that his passing was a great loss to many.
