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":

https://www.youtube.com/playlist?list=PLYPTUTcLMTK4jhJH769SKW6X1YBWLqYL7

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.

Hello Friends,

get this one in a maillist from ITEAD

@hek Very nice! the code are magic Very nice solution, i'll test this next days.

...
#include <ESP8266WiFi.h>
#include <MySensor.h>

void setup() { 
}

void presentation() {
  // Present locally attached sensors here    
}


void loop() {
  // Send locally attech sensors data here
}

Hi, if it possible to show a sketch with an ESP8266 WIFI => MQTT gateway? I figure out, that the received sensor data will automatic publish to my MQTT Server running on my Raspi. Then i can install this pice of wonderfull work in every room from my house

It's really fun project. Now mine is finished , but I do upgrades time to time.

Same by me, now i can mill my PCB's and i want to make a solder dispenser/pick and place header. my Dream, build a Header he can:

• mill a double side PCB
• put the solder paste drops to PCB
• put the (smd) components on PCB

I'll add this features to chilipeppr

lars, can we see some photos from your machine and maybe a foto from a milled PCB?

@ceech Nice Design, but you use a chip he is to expensive 4-6 Euro. Hmm, you now a alternative for this LTC4709?

Yes i got this (nice) machine last year from this shop. It's a kind of shapeoko2. The guy work hard, but he has to much orders. I guess a small xcarve are also ok. But i have to warn you, it's not a cheap hobby

Here some machines they could mill PCB's:

http://www.ebay.de/itm/CNC-3040T-DQ-Graviermaschine-Gravurmaschine-Graviergeraet-Engraver-Engraving-MILL-/271920866786 (IMHO the best for PCB milling)

I'ts a normal Lux sensor from my video lessions about Arduino save Power topic: https://www.youtube.com/playlist?list=PLYPTUTcLMTK4X3rSrr3FChxNeVwrH1Kmh

I guess the problem are not enough power, the node send some data and the power go down, then fall in reset and after some seconds the battery go up and the node try to send again and so forth.

At the weekend i'll test this with a new battery

Hi,

i have a node with NodeID in code. But in the last time i get only the presence message, after that nothing. What are happend here and how can i fix this?

Log from Pimatic:

<- I_LOG_MESSAGE  0;0;3;0;9;gateway started, id=0, parent=0, distance=0
<- I_LOG_MESSAGE  0;0;3;0;9;read: 25-25-0 s=255,c=0,t=17,pt=0,l=3,sg=0:1.5
<- Presented Node  [ '25', '255', '0', '0', '17', '1.5' ]
<- I_LOG_MESSAGE  0;0;3;0;9;read: 25-25-0 s=255,c=0,t=17,pt=0,l=3,sg=0:1.5
<- Presented Node  [ '25', '255', '0', '0', '17', '1.5' ]

Thanks for your help!
