3D Prototypes

Prototypes, prototypes!  Using sketchup, I created 8 different prototypes for the sensor. Using different printers and vendors (you can tell the progress), I was able to refine and identify physical flaws with the designs. Here...

ESP8266 with RFM69 using Lowpowerlab

UPDATE: interesting new git project: https://github.com/bbx10/nanohab I’ll want to try it out soon! I stumbled upon two different communities working on incorporating RFM into an ESP8266 environment or vice versa: Mysensors.org and Lowpowerlab. My previous...

Designing a Sensor Case

When thinking about how to track things, I explored rfids, barcodes, 3d scanners, bluetooth and other tracking options. The three main things I was looking for were (prioritized): 1. Power Efficiency (lasts longer than 9months)...

RFM69 to ESP8266

Given the popularity of the ESP8266, I am starting to test its ability to work well with the RFM69 chips. Here is how I’m connecting them (thanks to @chrille @mysensors.org) RFM69 <-> ESP8266: DIO0...

rf demo settings

Martin has been creating awesome little funkys based off of the jeenode boards. I picked up a couple v3’s with the newish rfm69 chips to try out their improved range and power consumption. After...
