The complete Python implementation for signature verification of Amazon Alexa

Our customer Veriset and its partners wanted to use Alexa to control a digital recipe book dizmo. No problem, we thought, integration is one of our strengths. Unfortunately it soon turned out that wanting to independently implement the Amazon signature verification is very cumbersome, due to the feedback process being very slow. It has been […]

Use dizmoGen to speed up your development workflow

Introduction In a typical workflow for developers, a lot of time is spent: compiling SASS to CSS, Linting code and validation, concatenating and minifying CSS and JavaScript deploying files to the correct location. All those tasks must be repeated manually every time you make a change to the source code, time you would rather spend […]

Navigator friendly dizmos

One of the unique features on dizmo is that one dizmo can remotely control another one. Take for example the Navigator dizmo: not only can it move from one dizmo to another (which is very helpful for a non-linear presentation) but also navigate from image to image inside the Slides dizmo! How does that work? […]

Raspberry Pi meets dizmo

Raspberry Pi, the credit-card sized computer and must-have for any tech-lab, has recently also claimed its place in the IoT world, which is how it grabbed our attention. Fascinated by its sleek looking 7”-touchscreen, driven by playfulness, we of course wanted to run dizmo on it. Such said, such done: We first made dizmoViewer run […]

Connecting a self-made prayer wheel to dizmo

This project was triggered by Xaver Inglin, one of our Kickstarter Backers, who has built a ‘Prayer Wheel’ and equipped it with the WunderBar-Kit created by relayr. The main objective was to then monitor the movement of the real prayer wheel and to visualize the movements by spinning a virtual prayer wheel in dizmoSpace accordingly. […]

How to write a to-do dizmo with backbone.js

In the first part of our tutorial series we built a basic to-do dizmo, using the dizmoElements library. Now, as promised, we will build a to-do dizmo using the Backbone.js library. Backbone.js is useful for keeping the JavaScript Code of your dizmos well organized, so it’s easier to further develop and maintain. You can work […]

Beat the heat with dizmo

The last few days have been very hot, and it’s almost impossible to have your room cool enough to sleep or work! Here at dizmo, we have an interesting solution for that…     Parts needed: Arduino Ethernet or Arduino Uno + Ethernet Shield DHT11 or DHT22 Temperature/Humidity Sensor DS18B20 Temperature Sensor Breadboard 2 10k […]

Arduino gesture sensor tutorial

In this tutorial, we’ll hook up a gesture sensor to a dizmo. We’re going to use an Arduino and WebSockets. Parts needed Sparkfun APDS-9660 Gesture Sensor Arduino Ethernet Level converter Breadboard Jumper cables Serial to USB Adaptor: Electrical hookup Our sensor, the Avago APDS-9960, offers ambient light and color (as clear, red, green, and […]

How to write a to-do dizmo

To kick off this multi-part series, we will build a basic to-do dizmo, using the dizmoElements library and later Backbone.js. Getting started Start by creating a new dizmo project with $ grace new Name your project ‘Todo’, choose ‘dizmo’ as your default plugin and ‘joose’ as your skeleton. Change into the folder of your Todo […]
