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...
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...
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...
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...
I’ve been interested in optimizing how we source, cook, and store food for many years. I started exploring ways to connect loyalty cards across grocery stores, which obviously met stalling resistance from grocery chains...
Building off of the teddy bear and xmas light projects, I added the LED panel and switch to our xmas tree! This way, friends would be able to leave us a holiday message we could...
Given we still live far away from our family and many of our closest friends, I continue to focus on creating ways to help us feel a little more connected. As my daughter turned...
Following last year’s post on being able to turn lights on/off, I decided to re-use it for this year’s holiday card. Users were invited to watch a live stream of our xmas tree and...
Unfortunately, Arduino’s Ethernet shield does not play very nice with other devices that want to use its select pins. After many searches, I came across jcw’s discussion board and Martin’s implementation doc. Because the...
