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...
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)...
The adventures in food tracking
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...
Earned Media Cube – A cube that calls
This is my first 3D printed internet of things (thanks to Matthew Epler for printing it!). It reads from BuddyMedia’s conversionBuddy internal api and displays lifetime shares and daily $Rev/share. The cube also makes...
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...
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...
RFM69 Initial RSSI Tests
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...
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...
Wireless Options – RFM, ESP, CC
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...
Almost Xmas Ornaments 2016
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...
Quick tutorial on programming a jeenode micro
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...
Media Cabinet Doors
I’ve had to pause and re-prioritize my time to focus on projects that could be done in 1 hour spurts. As such, I decided to venture into the therapeutic world of woodworking. As something practical, I...
