A wheelchair controlled by eye movements - Raspberry Pi. Myrijam Stoetzer, 14, and Paul Foltin, 15, are from Duisburg in Germany.

A wheelchair controlled by eye movements - Raspberry Pi

They have built a system for controlling a wheelchair using eye movements. A standard webcam with the infrared filter removed tracks eye movements, and the eye is illuminated by (invisible) infrared light from LEDs to allow the system to work in low light conditions. A Raspberry Pi is used to process the video stream to obtain the position of the pupil and compare it with adjustable preset values representing forward, reverse, left and right. The command is then verified with a switch that is currently manual but that should eventually detect small movements of the tongue or cheek.

Raspberry Pi + PiCam = Caméra de sécurité. Build Yourself A Raspberry Pi Spy Tank - Pi Supply. I actually spotted this project during Pi Day on Instructables where this project ended up winning first place.

Build Yourself A Raspberry Pi Spy Tank - Pi Supply

There are more and more people working on Raspberry Pi Robots and it’s great to see creators in the maker community adding their own twist to them. This Raspberry Pi Spy Tank is a fantastic example of this. The case for the tank was completely 3D printed and originally it was a GoPiGo robot kit. However, the project creator wanted to make his own version.

So, using the GoPiGo as the bare bones, he developed this. Below the video, you can follow the instructions of how to make this Raspberry Pi Spy Tank. Watch the video below to see it in action. Comment faire un routeur Wi-Fi DIY connecté à Tor avec un Raspberry Pi - Tech. C'est le week-end et vous êtes l'heureux possesseur d'un Raspberry Pi ?

Comment faire un routeur Wi-Fi DIY connecté à Tor avec un Raspberry Pi - Tech

Voici l'ultime tutoriel pour transformer ce mini ordinateur en routeur Wi-Fi qui vous conduira dans les méandres du web sans avoir à configurer Tor sur votre ordinateur. On ne finit plus de parler de la face cachée d’internet, que celle-ci soit stigmatisée comme place to be des terroristes ou appréciée par les passionnés de sécurité sur le web.

Incompris ou savamment utilisé, Tor est devenu un incontournable de l’informatique. Si vous êtes intéressés par l’exploration du deep web, vous savez sûrement qu’un des moyens les plus populaires pour y accéder est de passer par le navigateur Tor depuis votre ordinateur. Toutefois, si vous visitez fréquemment des sites en .onion, vous souhaitez peut être trouver une manière plus rapide de vous plonger directement depuis votre navigateur dans les eaux sombres de l’Internet. Avant toute chose, il paraît utile de préciser que ce tutoriel est plutôt simple. Matériel. Ressusciter la Game Boy avec un Raspberry Pi Zero. Que faire d’une Game Boy qui a rendu l’âme ou qui ne sert plus ?

Ressusciter la Game Boy avec un Raspberry Pi Zero

La transformer en console de jeu rétro en l’équipent d’un petit (mais costaud) Rasberry Pi Zero. C’est le challenge qu’a relevé wermy. Il a remis sa Game Boy « à jour » en la transformant en console de retrogaming grâce à Retropie. C’est la sortie du Pi Zero, sa taille réduite et sa faible consommation qui ont donné l’idée de cette réalisation.

Une fois modifiée, la Game Boy ne laisse pratiquement rien voir des modifications qu’elle a subies. La sortie casque a conservé sa fonction. Détecter le rayonnement cosmique avec un Raspberry Pi. Raspberry Pi, détection de mouvement. Infrared PIR (Passive Infrared) sensor provide very simple solutions for motion detection.

Raspberry Pi, détection de mouvement

All elements on Earth emit low levels of infrared radiation, however any body exposed to a heat source emits more radiation. PIR sensors are capable of detecting any change in level of radiation within their area of detection. For example, when a person enters a room, the sensor detects the change in the radiation level. For this experience, the following are necessary: a rapid wiring plate ; six sons of male/female connection; an infrared sensor PIR.

All of these components can be purchased in specialised trade. The status of the PIR infrared sensor can be read in the same way as the State of an input connected to a push button (Editor's Note: see reading of a button )). However, the PIR sensor does not recall resistance since the voltage delivered output is either 0 V or 3.3 v Enter the following code using a text editor (nano for example): import RPi.GPIO as GPIO import time appears on the screen. How to control a RGB or a WS2812 LED Strip with a Raspberry Pi. Introduction This tutorial will explain how to control a RGB LED-Strip with a Raspberry Pi.

How to control a RGB or a WS2812 LED Strip with a Raspberry Pi

It should work on all current Raspberry Pi boards. Attention: I'm not responsible for any damage to your LED-Strip or Raspberry Pi. Do this at your own risk! What do you need? A RGB LED Strip (with 3 pins for RGB and 1 pin for 12V DC) A breadboard Jumper wires (Male to Female) Jumper wires (Male to Male) Three MOSFET's (e.g IRLZ34N) Important is a threshold voltage of max. 3.3V (Mostly marked by an 'L' (Logic-Level) in the name) The MOSFET's handle like a switch which will be switched on and off really fast and so control how much of the specific color should be in your light A power supply (12V DC ~2A) A power jack Has to fit with the power supply I use one with screws so I can easier connect the wires The software pigpio installed on the Raspberry Pi 1. 2. 3.

Here is a overview over the GPIO pins of the Raspberry Pi: 4. 5. 6. What's next?
