Jeti RFID Battery-logger

My original intentuin was to make Revo-compatible propietary product I could manufacture and sell. Revo offered co-operation in Helifreak so I contacted them and they promised to come back to me, they never did.

So I did a cheap unit anyone can build and use instead.

There's several charger-manufacturers with bump-technology and all of them are different. If we would know all of these memory-blocks and their constructuon it could be possible to make a universal tag.

But like in Revo's case, that information is behind NDA and is not freely available, and that means it cannot be shared in a product built on Arduino.

So, in essence, practically impossible to make the wanted universal operation.

But, for Your use you could change the code so same memory-blocks are used, this is open-source, alter it as you wish, just remember to share

I think in the end that a DIY-unit built for 15€ (including 10 rfid-stickers) is better for all of us than a propietary, more expensive unit with closed code.

I don't immediately see it possible for me to sell these as ready made, I think it would be wrong since code used is open-source.

We have now one user using both your system and my RFID-sensor. When he uses it in "your" setup the "rfid-snsor data" is wiped out from the tag. We already looked at this, I stopped using block 2 since you used it and I'm instead using block 4 and 5.

What block are you really using? I looked at your code but it cannot be right that you would use so man blocks?

Hello Tero,

is there any Problem with your RFID sensor, when using HV equipment (BEC set to 8.4V).

Unfortunate news, I'll fix it as soon as possible: www.rc-thoughts.com/2017/01/rfid-sensor-...ulled-out-from-shop/

W.W: No, Arduino can take up to 12VDC officially, I have tested my boards to 12VDC. Arduino is voltage-regulated when input-voltage is connected to RAW-pin.

Hello Tero,

thanks for your info. The bug did't Impact me, because my batteries are all smaller.

Yes, it's mainly drone- or big plane users that are affected.

Hi Tero,

I was contacted by a french hobby friend who is using both the charger BID2NFC solution and your on board battery RFID "detector". Since the memory format of your solution and the 1:1 BID memory mapping of BID2NFC is not compatble this doesn't work together.
Do you see a way to combine both in order to close the circle. This would allow wireless parameter exchange at the BID-charger as well as battery detection in the model.

Have you been in contact with Ralf who made the BID2NFC code?

Best regards
Onki
