i know, terrible.. plenty of beer, sun and beach around here.

It seems that I'm placing a one-time order for wheels and pins next week sometime. Probably around Wed. The encoder wheels might be slightly more difficult to mail since they're thicker than the PCB's, but I'll figure it out. Looks like my blank boards will be arriving on Tues.

Thanks Dan,
You are the man.

I've got some encoders on the way so I'll be able to look into making them work, possibly on the stock board as well.

Mike.

I've been tinkering with a hardware design for a 'mega168-based TWI IO expander. Thinking about it now, it's got a lot in common with arduino boards... Maybe I'll just start with an I2C patch-in jumper board thing for the right gimbal/trim switch connector (would only work for mega64 boards, or those that have I2C on the same connector pins), then I can whip up a simple encoder monitoring program. I would still have to modify the '9x firmware tho.

I've just wired up a 'spare' encoder to a stock board as I suggested in viewtopic.php?f=7&t=1084&start=60#p19996. Both encoder lines and the encoder switch are wired to LCD data lines. All seems to work fine.
I've changed er9x to read these every 10mS, and keep track of the encoder movement (only costs 56 bytes flash to do this). The encoder counter follows the movement unless I really try to spin the encoder very fast, and I can only do this because it is a spindle without any proper control knob.

Provided the code is not too large, we should be able to have and encoder on er9x on the stock board. This assumes you can solder three wires to the ends of three surface mount resistors, which is easier than soldering the two wires to the processor pins for the telemetry mod.

Alternatively, the encoder should be able to be connected to the TelemetrEZ board, and send the position over the serial to the M64.

Mike.

I certainly would choose the TelemetrEX approach since I have not done the telemetry mod on my smartie 9X. May be TelemetrEZ would consider to put these connector pin header on it for easy integration.

Reading through the first few pages of the voice on stock board thread, it looks like people there were thinking along the same lines. Guess I'll spend some time today reading through those 38 pages and see where they are now. -_-
[edit]Nope... Looks like they took the simple hack approach.
On second thought, I think I'll go with the AT90USB1286 for my design. It's got native USB support (including a factory-programmed bootloader for programming over USB - no need for an ISP programmer), gobs of I/O, double the memory of the 'mega64, and already has a compact, low cost, arduino-compatable, breadboard-friendly development board built around it. I expect to see an "arduino leonardo mega" derived from this before much longer.[/edit]

How about seperating stock board discussion from sky9x board discussion, the sky board has another 12 possible in/out combos with a neat little processor that just needs programming.
Just to keep the confusion down.

Alright, so long as you keep your snarky, unconstructive comments out of my co-processor thread.

Lol, grow thicker skin.

He loves driving people mad, that's why

Maybe it's a good idea to create an encoder thread for er9x? another for open9x as well as I'm sure they will follow?

and icy cold beer for every one.

We might want to put the main hardware mod for fitting the encoder in the hardware section, it would be common to al versions. No need to repeat it several times.

Mike.

I will have to read all again, so I can learn what has to be done for the stock board and where to get what's needed.. couldn't follow the thread properly when on holidays. maybe someone could put the relevant info on one thread?

Joao

Great! Take notes and then you can do the wiki for it

hummppff..

still got 3 pages of unread posts to read..
It's your fault..

I guess I'll go kick that one off with info on the roulette wheel.

The 'nice little man' from FedEx brought me a package of lots of useful bits today, including some of the rotary encoders and an RN-42 BT module. Now 'all' I need is enough time to do everything.

Mike.

The fed ex man didn't deliver you any time? It's a shame we can't order more of that.

Got some progress going on... I finally feel like I'm giving a little back to the 9X community. Love it.

Very nice!

Looks like a piece of comtemporary art work to me.

Beautiful job Dan, can't wait.
Thankyou for that
Just one question, where do I buy the the Rotaty encoders from

There's a thought. Maybe I should start making my board designs as convoluted as possible, and open a gallery.

Anything, but anything has got to be better than Tracey Emin's efforts,
but what do I know about art

Just wait for my soldering of those pins on there, you will have a piece of genuine contemporary art to hang in the gallery.

Those are some sweet boards!

After some effort today, I've just about got one of these encoders installed in a stock Tx. It fits OK and the 4 switches work fine. I wired the encoder, and its switch, to the LCD lines as I described earlier, but I reckon the SMD resistors are too delicate to have wires soldered to them. I broke one of the resistors. Fortunately I have replacements so I fixed it. To connect the encoder on the stock oard, I thinkl we will have to solder three fine wires directly to the processor pins, as we do for the telemetry mod. The main problem is these pins are close to the telemetry mod pins and the wires will need to go in the opposite direction.

Mike.

Mike, I think I'm not understanding what you mean by opposite direction..
