RFM 69 RSSI Test
Initial RSSI tests 1. Next to each other in plain view. OK 25 104 101 108 108 111 33 (-27) OK 25 104 101 108 108 111 33 (-27) OK 25 104 101 108...

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...
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...
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)...
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...
After using Low Power Lab’s library and Martin’s initial sketches, I was able to test the RSSI of a sensor inside a big metal box. It was surprising to see how powerful the RFM69...
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...
Given the number of wireless options available and the countless modules I’ve used, I thought it would be helpful to put them all in one table. This table is based on data found on...
I didn’t have time to complete this project – so, I didn’t launch it – but, I’m posting my progress here so that I can leverage it in the future. The idea was to let...
After spending too much time looking for ways to program a jeenode micro, I figured I’d put together a quick tutorial. 1. Wiring between Arduino, Jeenode Micro V3, and serial monitor Uno 3.3V to...
