I was playing around with functional and reactive programming in Javascript, and the UI framework Cycle.js. In order to better understand how that framework works, I pared down the core functionality to a single concept: given a function that takes in an input stream and returns an output stream, resolve the circular dependency of feeding its output back into itself as input. I also built a naive re-implementation of the core Cycle.run command on top of that.

var xbee_api = require('xbee-api');
var C = xbee_api.constants;
var Q = require('q');

// following settings work for me on my Raspberry pi, your config may differ!
var xbeeAPI = new xbee_api.XBeeAPI({
  api_mode: 1
});
var serialport = new SerialPort("/dev/ttyAMA0", {

First experiments with NodeMCU to publish the current settings of my adjustable height working desk to MQTT.

NodeMCU can be found here: https://github.com/nodemcu/nodemcu-firmware

Note that you'll need a current version with support for floats (which the ultrasonic sensor library utilizes), I'm using 0.9.5 2015-03-18 with float support myself.

Support for the HC-SR04 sensor in NodeMCU can be found here: https://github.com/sza2/node_hcsr04

I provided my slightly adjusted version which makes measuring a non-blocking afair, allowing for callbacks when the measurement completes.
