Playing with my Raspberry PI and its GPIO over the weekend it occurred to me I would be able to control it in real time from a browser, using Socket.IO and pi-gpio. Here is a link to my Github code for doing so: https://github.com/fgheorghe/jsGPIO. The JSGPIOServer module creates an HTTP server handling Socket.IO events, producing […]

Having played with the Raspberry PI GPIO interface for over a year, I thought I should explore options for a faster CPU/RAM and a different architecture to enable quicker device control and more complex software. The fastest option for controlling is using a standard PC and a standard CPU architecture. After some research, I found […]

Tiny C program to loop a Micro Servo SG 90 from 0 to 180 degrees and back. Requires servoblaster. #include #include #include #define SERVOBLASTER_DEVICE_PATH “/dev/servoblaster” #define SERVOBLASTER_PIN 2 #define MIN 60 #define MAX 250 #define STEP_INTERVAL_MILLISECONDS 960

Here is a short code snippet for relatively low latency video streaming using a Raspberry PI camera via the HTTP protocol, and viewing it in VLC. This post is inspired by a ‘netcat‘ approach found here. Code for creating an HTTP Video Server: var spawn = require(‘child_process’).spawn, child = spawn(‘/opt/vc/bin/raspivid’, [‘-t’, ‘0’, ‘-w’, ‘300’, ‘-h’, […]

This entry shows how to create desktop applications for the Raspberry PI with a GUI written in JavaScript and rendered using the Java SWT Browser widget. Use this model to benefit from Rich Internet Applications and access device hardware and software resources by creating custom JavaScript functions. The assumptions are that your device is running […]
