Raspbery Pi [streaming]: Stationary Recording/Playback Training Assistance System

Goal:  To create a mini-system for sportsmen that allows: to sportsmen (ex. wrestlers) to record their training routines with purpose to analyse it right after the routine completion by observing on a tv-screen. This is supposed to assist in fixing of the mistakes yet during the same training session. to play pre-recorded training video-materials…

Raspbery Pi. Getting Started with IR receiver using lirc-rpi overlay

really? no coLIRC – Linux Infrared Remote Control Connect your IR receiver to your RPi. TSOP series are most recommended due to their satability (ex. TSOP38238 IR receiver (ebay) – specification) Make sure you are connected to Internet: ‘ping google.com’ should produce answers from some IP address After connected to Internet, install ‘lirc’: sudo…

GETTING STARTED: Dynamic DNS (DDNS)

Ingredients: Router with DDNS feature support. Ex: RT-AC66R ( ebay ) DDNS provider (ex: no-ip) http-server exposing some service at some port and running using static-IP Steps: Sing-up for DDNS server provision and specify your host-name (ex: intelmakers.ddns.net) Configure your router’s DDNS settings At your router, add your service to port…

Arduino: Self-switching corridor lamp (motion detector, relay)

Project Idea and Requirements by: Masha Lipshits Goals: – to learn using Arduino uC, relay and motion sensor – using Arduino Pro mini, to make our corridor lamp automatically switching ‘On’ if motion is detected in the area of the entrance-hall. Switch ‘Off’ – by timeout. – finally installed prototype shall be extendable (ex.…

Raspberry Pi Experiment 01: PiCam Video Streaming via WiFi

Video [No Voice]

 

Experiment Goal:

To enable the following features:
– capturing of live video by means of Raspberry Pi Camera module
– streaming of the captured video to custom PC Client

Constellation:

1) RPi PI running Raspbian
2) Server side is running on PI (Python script) waiting for 1 client to connect (TCP)
3) Video streams to connected client (Linux/Windows) in mjpeg (configurable # of frames)
4) C# client application using VLC WPF-control to display the video inside the application window. Start stop streaming commands are send to RPi trough TCP-IP

Components:

– Board: Raspberry Pi model B or higher (RPi-Model-B ebay/RPi2-Model-B ebay)
– OS SD-card: NUBS (preinstalled/self-made after download)
– Camera: Raspberry Pi Camera module  (ebay) or PiNoIr Camera module (ebay)
– Wi-Fi:  EdiMax EW-7811Un (ebay) dongle

Constellation:

Raspberry Pi: Getting started with Wi-Fi

Reviewed by Editor: Jack Allison To have you RPi connected through Wireless LAN (Wi-Fi) you will need an appropriate USB-dongle. I used EdiMax EW-7811Un (ebay). Although it has lower data-rate specification (150 Mb), there are some advantages: – small form-factor (size): good for small products/prototypes – fully supported (in plug-and-play fashion) by Raspbian…
