dimensions of the pro mini

Dimensions:

0.7x1.3" (18x33mm)

small enough??

on my dividers I don't connect the ground on the battery side.. only on receiver side..

I wonder how healthy the regulators are...

Did you see the one I've posted above? it's the same price and already works at 3,3V and it has a regulator (max 12V) in it.. In theory could be connected to battery voltage without putting more load on the tx regulators.. and it is small..
Also, no mods needed as far as I can see

DC input 3.3V up to 12V

Low-voltage board needs no interfacing circuitry to popular 3.3V devices and modules (GPS, accelerometers, sensors, etc)

what about this??

hhmm, sometime ago, if I remember correctly, someone fixed his board and after replacing the regulators still didn't have battery power on the 5V one.. the problem was a burnt trace near the LCD plug I think.. I'm going to try to find the thread.. EDIT: Found it. Maybe this helps ;) http://openrcfor...

I downloaded the tool to encode the wav files.. is there any way to listen to ad4 files without having the module??

Another thought.. If you do decide to go for the most complicated version (with the pin17) could the people that already did the telemetry mod just leave the wires connected to the mega 64 pins and these be used as extra inputs for switches?

I know, shut up João..

You bet I will.. just can´t wait to insulting myself :mrgreen: So, are you actually going to try both versions? I´m asking because I have one tx with the telemetry mod already in it and a new one still stock.. I do like your last option using the pin 17 as we can still control the backlight that way...

That´s even better. it should be enough. is that the one that Mike referred to??

With a little amplifier that someone posted on these forums a while ago using a LM386 I think, that could be achieved easily.. it can drive a little speaker or headphones, or both with a switched jack plug.. that´s not a problem.. I´d personally go for the 500W amp.

Exactly, I fully agree with you.. But when people are stubborn, even if you show them it's like talking to a brick wall.. And it's because of the under educated comments as you call them, that I say that this is now personal :mrgreen: I'll probably end up kicked out of the club, cos he's the preside...

watching a friend of mine from the club flying with his monster vario in is glider, with a radio receiver hangging of his neck to receive the audio and saying that it was really cheap (250€ second hand) really made me laugh.. and then I told him about the possibility of the 9x doing it much cheaper ...

You could also make the vario sound playing different files for different values on one side of a switch, and when this switch is flicked could give you altitude for example.. but that's another story.. that is software.. Like ReSt says, the first step is to choose how do we want the hardware to wor...

Top man Showmaster..

if I was in the USA I'd definately buy from aloft.. great costumer support, not expensive, and very quick.. the killer is the overseas postage..

I'm sure there are people that gladly help you but you have to let us know where you are.. maybe someone live not so faraway from you and can help you..

No, there's nothing wrong with the audio mod :D The audio mod I keep magging about it's still in the works, hence my nagging signature down there ;) this one will let us hear voice alarms (or whatever you want to hear ;) ) .. But this one will still take some time. There is another audio mod which u...

Please enter model configuration by pressing long the right key, then go to the LIMITS menu and there you can set the sub-trims.. I don´t remember and I don´t have the radio here with me but the name of the setting for the s-trims might be called OFFSET..
Please someone correct me if I´m wrong...

picture/s??

Mike, you're the man.. yesterday at the club I mentioned this mod and some ears went up.. After a while I found out that another guy there has er9x telemetry but never said anything because of the other people.. Count on me for testing.. My knowledge in electronics is not very advanced ( I left when...

Did you read this part??

There are a couple of things that you have to get used to here.. To be insulted (in a nice way :D ), and to drink beer.. ;) As you're probably used to the second, just get used to the first.. :mrgreen: :mrgreen: By the way, this forum is a big family. At least is how I see it.. Lots of nice people w...

yeah, the green LED just flickers.

yes, I understand. thank you for that.. I'm sure there is a good way to do it..

Mike, did you check the arduino pro mini for 3.3v? then could we have a direct connection with the module? I guess it would still be a problem to interface the mini with the mega64?? sorry about all this questions.. you know why

Yes, that's correct.. the audio amp will most likely be powered by battery voltage.. the arduino and sound module will have their own voltage regulator/s.. they don't take much current.. I don't know the modules voltage but in case it's only 3.3v there's also a version of the arduino pro mini for 3....

Yes, but the initial project was to make the most out of this cheap chinese radio.. and I believe it still has much more to give ;) I can afford to buy a couple of arduinos and cheap sound modules for both my radios, but not able to buy a couple of ersky boards.. I do believe that the ersky board de...

Thank you very much for looking into this..
One thing makes me laugh tho.. knowing that the Atmega in the arduino is much more powerfull than the one in the tx..
