Android+Arduino – Face Following RC Car

To some of us, hacking an RC Car to simply follow a black line or avoid obstacles is too easy, and we’re sure [Shazin] would agree with that, since he created an RC Car that follows your face!

The first step to this project was to take control of the RC Car, but instead of hijacking the transmitter, [Shazin] decided to control the car directly. This isn’t any high-end RC Car though, so forget about PWM control. Instead, a single IC (RX-2) was found to handle both the RF Receiver and H-Bridges. After a bit of probing, the 4 control lines (forward/back and left/right) were identified and connected to an Arduino.

[Shazin] paired the Arduino with a USB Host Shield and connected it up with his Android phone through the ADB (Android Debug Bridge). He then made some modifications to the OpenCV Android Face Detection app to send commands to the Arduino based on ‘where’ the Face is detected; if the face is in the right half of the screen, turn right, if not, turn left and go forward.

This is a really interesting project with a lot of potential; we’re just hoping [Shazin] doesn’t have any evil plans for this device like strapping it to a Tank Drone that locks on to targets!

An Arduino-based ADB-to-USB adapter for NeXT keyboards

adb, Hacks, Hardware, keyboard, NeXT, reverse engineering, USB Commenti disabilitati su An Arduino-based ADB-to-USB adapter for NeXT keyboards 

Have you ever wondered to use your old-fashioned NeXT keyboard with your current, non-ADB computer? The main issue that needs to be solved regards how to interface this ADB keyboard (standing for Apple Desktop Bus, an old protocol used in former NeXT and Apple computers) with a standard USB interface.

In this nice tutorial, Ladyada and Pt describe the approach they have used, based on an Arduino Micro board and… some luck in searching for the right information about the scancode table of the keyboard  ^^.

More information can be found here.
