Hey Friends,

i'm proud to present my small VideoSessions (2) to describe the complete process to mill a PCB with chilipeppr. I hope you like it? Comments are welcome!

This Playlist describe the process (Eagle + Chilipeppr + Prepare CNC + Mill on CNC) on my CNC (eShapeoko) to made a PCB with Chilipeppr and GRBL.

Hi Friends,

here some videos (german!) about my new "XAmbi Kid mini pro":

You can use three different Transceivers:

• RFM70 or NRF24L01(SMD) with mysensors.org library
• RFM12B or RFM69X with jeelib library

The PCB are shared at oshpark: https://oshpark.com/shared_projects/ezK4aEQd

And here some Features:

• use a normal Arduino mini pro as stacked interface
• optional you can add Magnetometer HML3358 and/or SHT21 (Temperature/Humidity)
• powered via coincell CR2032
• small Footprint (25mm x 41mm)
• holes to screw on a enclosure
• extra pins for D2 - D9 for ur external sensors
• extra I2C pins
• Flash for OverTheAirUpdate's

Some Features are not testet now, but i will publish some news about this Project here.

You like it? You want some more Informations?

Ok, write here in this thread

Hello,

first of all. This is my first thread in this Forum

I realy like the concept from mySensors and found this some weeks before. I read all the nice Tutorials and Builds and will show my Concept:

https://xpix.github.io/XAmbi/
https://github.com/xpix/XAmbi/tree/master/Xambi_kids

The Features:

• small footprint (50mm x 28mm)
• use standard RFM12B Modules with small poweruse
• design for this enclousure: (PDF)
• works with standard Coin cell (CR2032) for a ~year
• has a (optional) Booster on board to make 2.5V to 5V for special sensors or relais
• infraed led for TV or IR serial IR communication
• special Sensorboard for stacking

The Software on this kids use the JeeLib:
http://jeelabs.net/projects/jeelib/wiki

The Xambi Gateway:
https://github.com/xpix/XAmbi/blob/master/Xambi-RPI-Gateway/README.md

I use a very robust library with a lot of Features, support the RFM12 and RFM69 Transceivers together.

Here some photos from the last version 0.4:

Ok, it's enough ... a before i forgot. At this time i work on a MySensors Transportation library:

Hi, may somebody are interested about my Prototype to connect 4 types (RFM12x, RFM6x, RFM7x, RFM9x) of RFM Modules to Raspberry PI:

Hi, i ordered some boards from OSHPark and at the weekend i solder this thing together. Here a pic from my work

Ok, it's work. You see, i have old nrf24 Modules they have not the same pinout, but i ordered some here in germany.

Some points to the design:

• this pcb has on both sides small SMD Components, that very hard to solder. I solder my one with an IR Oven and can only solder one side. It's mostly ok becouse on the second size i can solder with an iron, but never 04 components
• the size of smd components are too small, i understand this when you use the small Atemag328p MLF and only 04 components. Better are 0603 or 0805.

Ok, enough ... the board are great and give me a lot of ideas to my board. my are a small bigger but use the nrf24l01+ SMD version and a normal arduino pro mini. Please have a look:

Here with installed HML5883 Magnetometer, but sadly doesn't work.

Don't know why, but i decided to rework the design and replace all I2C sensors with a Solarcharger/Supercap-PowerSupply and add a voltage booster for 5V.
