Re: Sky9x Rotaty Encoder Option

Wow... Very clean compared to my Dremel cutting work. Yeah, I'm going to go ahead and declare that design public domain (after all, it's just a glorified jumper board). So anyone that wants to make these PCBs, feel free. Sell em? Go for it. Just don't try to stop others from doing the same. As for m...

Re: Sky9x Rotaty Encoder Option

Well, using a quadrature decoder and counter chip could mean it gets read constantly. There would be some speed limitation due to rise/fall times on the wiring and chip IO pins, but that'd probably be a matter of a few uS. The main processor could then periodically check the value on the counter, fi...

Re: Sky9x Rotaty Encoder Option

IF you are going to put a processor in between the encoder and the Mega64, then why not: 1) Connect the 4 direction switches to this processor. 2) Connect the encoder and its switch to this processor. 3) Use the 4 connections that were the 4 direction switches to connect this new processor to the M...

Re: Sky9x Rotaty Encoder Option

Maybe we need to add one of these http://www.usdigital.com/products/interfaces/ics/lfls7183 and a counter so we don't miss any pulses? While that's an interesting idea, I suspect that in practice, the converter and counter ICs together would cost more than an ATmega168 ($2), ATtiny or similar low-e...

Re: Sky9x Rotaty Encoder Option

How much space do you have between the sky9x board and the PCB for the encoder? About a centimeter. I took some pics last I had it all apart, but they're on my computer at home (at work right now ^_^). I'll post one up later, along with the quick vid of operation (though the encoder/center button i...

Re: Sky9x Rotaty Encoder Option

Alright. I'll have to look at actual material costs, but I don't expect it to be more than a buck or three per board, plus shipping. Everyone that wants etched but otherwise unfinished PCBs, PM me how many you want so I can get an idea of how many I need to make.

I'm willing to do a short run once I get all the details ironed out (which includes figuring out the rest of the etching process). Though really, I'd be perfectly happy to hand off the design to an open source PCB site.

Re: Sky9x Rotaty Encoder Option

Ok, noob mistake: the traces in my project are on the "top" layer, which is the same side the encoder part has to be on due to its asymmetrical pin locations. Not only does that mean the encoder couldn't be soldered properly, but solder mounds from the jumper pins (down to the stock switch locations...

Not really. The tabs are there to rest against the screw posts as a depth limit. They're not supposed to be drilled or otherwise used with screws. I just used the screws for the sake of showing that everything lines up nicely.

Re: Sky9x Rotaty Encoder Option

Is this only for the sky9x board, or also a possibility fior the stock board? It should work for both, as well as other aftermarket boards. All of the replacement main boards (that I've seen) keep the pads for the stock clicky (tactile) switches. This setup reuses those pads for mounting as well as...

Re: Aurora gimbal usable ?

is it even possible to switch the gimbals without the ersky board?? Yes. The voltage range that the aurora gimbals produce can be "stretched" out to what the '9x board expects by using an analog op-amp circuit. MikeB provided such a circuit on RCgroups: https://dl.dropbox.com/u/9882625/MikesGimbalO...

Re: Miniature joystick for camera

Yes, though the playstation gimbals are much larger than the thumb-slide joysticks. The footprint is comparable, but the slides are nearly flat. Using the gimbals' associated playstation knob/sticks will likely pose a problem as they have a spherical dome-base that shields the gimbal - the gimbal wo...

They're about the size I expected... If anything, maybe a little too small diameter-wise.
