@aze No Problem all the time nice to hear idea from people

@anticimex You are too fast Now the CERN files are uploaded!!

Hello, interesting project. I am looking for some relays 10A, but i do not find under 5VDC. Where did you buy them ?

Hi, Is this a finished solution? Just plug the 2 aaa batteries and play? Or do i need to solder everything my self? Also the magnet reeds you talk about are these those one? https://cdn.sparkfun.com//assets/parts/1/0/4/4/0/13247-01.jpg How to connect? Thank you

@prakhar-birla - well the idea with MysX is that the pin-order is fixed so you can attach any daugherboard to it. If you start mixing the pins around you will not be able to transfer a daugherboard from one motherboard to another since they will be different. Im not sure how MysX would translate to other MCU but other have digital and analog pins as well - so it would be most possible to connect MysX to other mcu. About the external interrupt you are right, there are 2 on the atmega328. On my Nrf24l01+ version you can use D2 as an interrupt but since the RFM69 radio uses this pin you can not on this version. D3 is your only choise and if you need more you might have to create an external circuit. As I said, I havent had time to look over SPI flash instructions yet. I havent even tried it - this is a user request from this forum. You can search this forum for more information - like this: https://forum.mysensors.org/topic/3160/ota-flash-types-for-mysensors/

@schif Hello, Thanx for you comment. Yes you can use it but use a ceramic capacitor

the message sending time was reduced to 10 seconds as in the debug mode. There is no difference in the dry sensor or in the water.

Hi @koresh - I had a little accident on the AC side :-). I was wondering what values the 2 resistors (TH and SMD) and diode are ? Thanks!

Hi. Do you have unassembled pcbs to sell?

@gohan Yes, you are right, this is done by cnc router.

@GertSanders ok, strange. standard pin headers fit for me only into FTDI and ICSP pin holes. Into the other two 8 pin rows it does not fit.

@yoonie said: For the pro mini version, should i create another Openhardware project, or should i put it here, in the already existing project? Might be better to create a new project as they uses a different set of design files.

this kind of optic fiber is probably only plastic so for a full DIY , you can use also fishing wire with a big power led or an old chistmass tree optic fiber lighted.....

@zeblong, you can generate these from the board files, however i'm leaving this one for @Ivan-Z to discuss with you as this is his device and he knows all details regarding this.
