I think there’s too much time I did not talked about ULPNode project, good news, it’s now time to talk about it and it’s timeline. And it’s difficult to find a good starting point since all that I will describe… Continue Reading
ULPNode RF Protocol ULPNode RF Radio protocol was intended first time to be part of ULPNode library, but as soon as I tried to compile gateway code for other target as ESP8266/Particle/PI and others, some targets env compile all source… Continue Reading
Currently working with Ultra Low Power nodes project (formerly ULPNode), I was searching for a small but powerfull gateway. What job for this gateway ? My goal is to be able to do a lot of thing with the gateway, even having… Continue Reading
After several articles and some intensive tests with ULPNode, it’s now time to explain how the low power engine has been built. Even if you can find plenty of Arduino clone node, when it’s time to power them with battery… Continue Reading
Today I wanted to do a quick project status of the 1st prototype of ULPNode I received some days ago. After the introduction of ULPNode, and both articles about bootloader (1 and 2) used, for this one I will start with… Continue Reading
For some time now, I’m using great RFM12B RF modules to transmit data from my nodes to my gateway and then post data to emoncms. I started to play with Jeelabs library but switched to Felix (lowpowerlab.com) library improvement on.… Continue Reading
I’m using day by day a custom board to debug and test my Arduino code. My board exposes an NRF24L01 connector that I’m using also to connect lot of devices (RFM12B, RFM69, MAX18355, SD, FLASH, …) mounted on a breakboard… Continue Reading
Use RFM12B, RFM69CW, RFM69W or RFM69HW, Micro SD or Flash EEP with NRF24L01 connector of ArduiPi board (or other) Updated 2014 September I created 3 other small boards, V1.2 without SD but very small, the V1.2 SMD ultra small (version… Continue Reading
