thanks

About the enclosure. We don't see very Well on the pics but I have extruded a mysensors text on the internal face of the top part. By doing this, the letters let the light of the arduino led pass through the plastic. It give a great effect

Thanks for your compliment.
It's only acetone steam (only cold steam because I dont like the idea to burn acetone).
The treatment is very simple : 3 hours in a closed box with 2 kitchen sponges on wich I versed the acetone.

Thanks for the compliment.
About your questions : for this pcb I have "nothing" under the radio antenna (no copper trace) but I've not think about the arduino nano on the side ^^. But that's ok, the node is working great for my house (about 50 meters max)
For the first node, I use a classic HC-SR501 from Ebay. It works like a charm

Another pic of the 3d printed enclosure. it's 50x50mm (external dimensions)

Hello

I want to share my new projects with you. I've made 2 new mysensors nodes for my house.

1 - Motion sensor on battery -with hacked enclosure.
I've found on a local retailer a motion sensor with leds (2 $ cost) lol
It was perfect to hold a mysensors node. so I just opened it replace original electronic with my own. (atmega 328p running at 8mhz, nrf24l01 and motion sensor). Now, some pics of the node

The final node :

2 - The second node is a gateway for replace the one I actually have. I've designed a pcb to hold an arduino nano and the radio. (I've also added some sensors inputs to use the pcb for other things).

The pcb

For this one I've designed and printed a little ABS enclosure with my prusa

At the end, for visual purpose I've applied a smoothing and polishing process with acetone

The final node :

Hope you'll like the projects

Yes. you're right

I just buy some CR2032 supports for pcb on ebay. I hope it will drain enouth power to run the node

Hi

I just finish the box for my new sensors. Just want to share it with you

Thanks for your answer. I'll keep them in mind for the future version of my board.
However thanks for the compliments

Thanks for your answer.
Yes it's a good idea to move the nrf because I've allready experienced reception problems. It's possible that's the cause was the position of the antenna. Thanks for the tip

Hello

I want to share with you my new little project. It's a pcb board (designed with eagle/produced by pcbway) for an easy integration of my future mysensors nodes.

the functionalities are :

• socket for atmega328p-pu
  -socket for nrf24l01
  -isp socket for programming the board
  -power supply : 3v - 20v
  -support for mesuring and reporting the battery level to the gateway
  -i2c socket
  -digital i/o for the sensor

Some pictures of the board :

I'm actually working on a v2 of the board with a micro usb port and smd mounting with atmega328p-au (to save place)
