Juicebox HTML5 Responsive Image Galleries |
The Juicebox module helps integrate the Juicebox HTML5 responsive gallery library ( with Drupal. Juicebox is in many ways the successor to Simpleviewer and offers a powerful and responsive image gallery front-end that's based on HTML5. See the project page for a detailed feature overview. Installation (7.x and 8.x) Install and enable the required Libraries API module (version 2.0 or above) from Download the 3rd party Juicebox library from and extract it to a temporary location. Both the Lite (free) and Pro versions should work fine with this module, and the one you should choose depends on how much formatting flexibility you require. Copy the appropriate core Juicebox library files that you just extracted to Drupal's library directory. Typically, this means you will create a new directory called /sites/all/libraries/juicebox and then copy the full contents of the Juicebox "jbcore" directory to this library directory. You will end up with a structure like /sites/all/libraries/juicebox/juicebox.js and /sites/all/libraries/juicebox/classic/themes.css, etc. Install and enable this Juicebox module.

Encoders software debugging
This time, it's simply about these small and cheap rotary encoder knobs which one uses often as input controls, replacing analog potentiometers or whatever. Basically, these are quadrature encoders like others, but when using these as user control inputs, for example for a midi device, you don't need a huge numeric range to count millions of turns at 0.1° angle resolution.

The problem with these mechanical switches is that these bounce. That means that instead of simply closing a contact

Teensy 3.1 with ESP8266 Web Server
I like to experiment with various RF devices. I have tried the Arduino Yun, CC3000 breakout board and the ESP8266 model ESP-01. I have a general task that I like to use to find out difficult a device is to use. The task is a web server that allows a browser(hopefully any) to turn on or off a LED connected to the device. The current flowing through the LED is measured and reported. The ESP-01 is the version of the ESP8266 that uses"AT" commands to setup and use a WIFI network connection.

A Guide To Using ESP8266 With TEENSY 3
Work in Progress
The ESP8266 is a very low cost Wi-Fi connectivity solution.
It consists of a 802.11 b/g radio and 32 bit microcontroller.
While one can program the ESP8266 MCU directly, I'm not ready to learn yet another programming environment.
For me the Teensy 3 is ideal for a host controller and since it is a 3.3 volt device, it is directly compatible.
I am hoping to pull the information together in one place to save others the frustration I had getting started.

ATtiny i2c Slave – The Wandering Engineer
I'm working on a project where I need several sensors that communicate back to a central processor.  Since I'll have several of these sensors I need them to be cheap and the ATtiny85 jumped to mind.  The only problem is that I've never used i2c with the ATtiny series before.  I read dozens of "tutorials"…
