One antenna for DHT and the
other for a spektrum hack module.

Oops, good point!
With the same protocol, I suppose.

Klaus

Question: Is it illegal to use the old protocol or is it illegal to sell new TX that uses the old protocol?
If the second choice is true why shouldn't a new RX be able to listen to the old protocol?

For those who struggle with the command line parameters of avrdude
there exists a splendid GUI for WIN and also Linux and OS X: avrdudess.

The required voltage depends on the length of the resistance wire.
Current is what counts (in fact it's the wattage).

Edit: 5A should be more than sufficient. up to 3,5A should be enough most of the time ...

I used this method more than 40 years ago when I started my RC career when the thumb method was not en vogue at all and so I do now for a few years since I restartet after 30 years ... No final adjustments when the TX is hanging from my neck! If there is the need to I do take the time to remove the ...

In absence of a helper for taking a picture ...

Just a 3 mm screw and some washers ...and yes, it's not built for blacksmiths ...

Are you kidding me?

I don't have my boards yet so I can't proof it by experience but:

via the black wire 9XT receives data -
so the black wire has to be hooked to DHT's Txd,
therefore the white wire to DHT's Rxd
and that's it.

Here the firmware I flashed to my USBASPs for using them with my 9Xs with 2561 processor.

Klaus

There now resides a rotary encoder ... I'm no friend of this centered neck strap supports.

This is my prefered solution:

While still waiting for my boards (even snails seem to be quicker than our customs :cry: ) I do prepair my 9Xs for them. So I did the current protection mod with an alternative diode, the 1N5822. Here 2 pictures that show how it can be installed: (Also you see here an easy way to get rid of the buzz...

There is no dumb question!

Or maybe because it's useful to switch languages at the field... Some like to use e.g. german language version here (e.g. elder people). But if there's a specific question at the field I'm glad to be able to switch to english version to which I'm used to / familiar with (even though my mother tongue...

In addition: Once a parcel reaches german customs you don't get any further tracking information...

Klaus

I made the experience that parcels from asia arrive here in a few days.
Then at the customs it can take up to several weeks till the postman rings the bell.

Klaus

I still haven't asked for tracking numbers ...

Waiting for my 9Xtreme boards I have 2 questions: The 9Xtreme board is supporting two TX modules. Are both ports able to support DSM (for harvested Spektrum modules) or do I have to take care to which one I connect the Spektrum module? Is there a possibility to read telemetry from a DHT directly in ...

On my Pro with newest test fimware I made the experience that welcome.wav in system directory
is taken prior to 0028.wav in voice directory.

It took some time before I noticed that.

Klaus

Very fast ...

Sigh, I'm curious about the time the boards with my name on 'em
have to rest at the german customs

Klaus

Hi João,

thank you for your efforts making this sound-pack.
Concerning the various welcome messages I went a completely seperate way : Klaus

Isn't there a possibility to manage it like the Pro?
Automatic bootloader mode when USB connection is established before power-on?

Klaus

An old german saying there comes to my mind:
Sometimes you don't see the forest because of all the trees ...

It's just too simple. I stepped into the same trap a while ago.
When the cursor is on this box just press MENU and the actual position of the switches is captured.

Switches that are in ON position are displayed inverted.

Klaus

Hi João,

many thanks for that tutorial especially for the antenna thing.
As bluetooth also works with 2,4Ghz what do you think about using standard WIFI antennas?
The idea is to use an old router as a donor ...

Klaus

Hi folks,

here is my solution to "protect" the 78L05 on the switchboard:
(please don't take it too serious ...)
s.th that isn't there can't go faulty

Klaus

Something like this or that?

Maybe this can help with Sam-ba.

R818 is for 9X
R217 is for 9XR Pro

what you need is ersky9x for 9XR-PRO which you find on www.er9x.com.

Or the latest test version you can find here.
