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
Following the 1st part of bootloader description for ULPNode this article describe what modification have been done to optiboot to be able to drive new Ultra Low Power nodes. Optiboot For this, I started from original optiboot (latest trunk from google code)… Continue Reading
Following the previous article presenting the ULPNode it’s now time to deep into the technique used to setup the starting mechanism of ULPNode bootloader. In this 1st part I’m introducing the goals to achieve and in the 2nd how it has… Continue Reading
Why this new project ? For some time being, I researching a way to have to have a kind of “universal” Arduino node sensor. When I say universal, I’m talking about connecting to it several sensors type (Temperature, Humidity, Lux,… 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
