THEMA:

It's time for a cold one

Hi Tero,
I got the small RC522 reader boards today and replaced my older large mfrc522 ones.
The smaller boards work great and the whole module is now much more handy.
Tomorrow I will test my 25mm tags again on the smaller batteries.

Thanks for the advice with the small board. Since I just have a DC-16 I cannot use your reader solution. But I usually have only one battery per glider so there is no real need for a detection in the glider (and space is also a precious thing ). My main goal is to identify the battery at the charger wirelessly as I use many different types during the day.

Best regards
Onki

... that´s my hope for the near future; a solution for a Junsi 4010 And I know Tero has already a Junsi 4010 ....

Hi Jochen,

This is why I modified the Robbe charger (with the software support of Ralf). It is already using an external memory (BID) which is just a serial (I2C) EEprom. This will be emulated by the wireless solution.
Junsi has nothing at all regarding this. Neither a hardware bus to allow external Memory to handle nor a firmware support of something like this.
I wouldn't say no but I am not very optimistic to have a solution for Junsi as they are not preprared for such things.

There was just a power battle going on the last couple of years but no real usability innovation. Battery paramaters are not manufacturer specific so a kind of standardised format is needed.
But the manufacturers of RC equipment are not very well known to talk to each other:angry: .

Best regards

Hello everybody,
Excuse my bad English. Try to ask my questions. First of all thank you for the very interesting project, which I now also want to have in my helis. The order for two sets has just left.
First I have to know, does this work with my old DS-16 which is still equipped with the black / white display?
Then I bought the RFID sensor: www.ricardo.ch/kaufen/modellbau-und-hobb...badge/v/an837023152/
Is it operated with the same Arduino code? And how is this connected to the Arduino? What is the operating voltage of the Arduino mini? One model has 6V and the other has 8V BEC voltage.
Thank you in advance
Greetings Thomas

Funbug: Your reader works fully with Arduino. With DS-16 you will get these sensors:



And you can have them on your screen:



Unfortunately no log since that is LUA-app. But your usual Jeti-log will show you what battery you used.

Onki & Jochen: Well, your both right and wrong. Junsi does have a way to control 306,308 and 4010, it's the modbus protocol available both in USB-port and in serial RS232-form from headers J1/J2 (Servo-test pins). My whole iCharger Touch is built on modbus so yes, it can be controlled almost fully from it.

here's the (poor) datasheet: www.foxtechfpv.com/product/chargerpowers..._MODBUS_Protocol.pdf

There's one thing that you cannot do from modbus, you cannot start "GetIR", but you can charge desired channel with desired values. (Example: "Start channel 2 with LiPo-program, current 30A, fast charge, etc etc...")

What comes to modbus-protocol I am planning a release of executable binary of it this winter. (Binary only, no GUI since it's a freaking mess). Binary is for *nix-platform and currently only for ARM-architecture so I have some work there too. For reasons I'm not explaining here source-code on that will not be public.

And yes, I'm sure my iCharger Touch will have Bump before next season starts, now that the heli-part is done
