Winding the inductors is easier than you might think! I used about 4 feet of 18GA Magnet wire to wind the inductors for this particular power supply. Each inductor has ~30 turns on it for an inductance of about 90uH. If you don't have...
In this step, how the Arduino shield stack gets assembled, and how to wire your wave shield will be discussed. If you remember the note from the top in step 1, You hopefully used stacking headers to build your wave shield. If you didn't,...
Cannon code- #include "Servo.h" // include the servo library Servo armServo; // servo to raise the arm Servo cannonServo; // servo to recoil cannon // these constants won't change: const int triggerSensor = 1; // the sensor is connected to analog pin...
Make Processing control Arduino THE FINAL PROGRAM:So,you have started drawing on Processing. Now, you'll 'feel' the drawing!Imagine you are blind (remember, this device was invented for blind people to draw on computers):How would you feel a raised line...
For this step you will want a variac or some way to limit the mains current. You might want to put a lamp in series with the hot wire to the transformer (are you sure you're comfortable working with mains electricity?)Connect everything up as you did...
OpenWrt setupI use GPIO 29 so for input the setup looks like this:/etc/rc.local: # Put your custom commands here that should be executed once # the system init finished. By default this file does nothing. echo “29″ > /sys/class/gpio/export; echo...
Output:And /etc/rc.local for output # Put your custom commands here that should be executed once # the system init finished. By default this file does nothing. echo “29″ > /sys/class/gpio/export; echo “out” > /sys/class/gpio/gpio29/direction...
Test fit all the components in the box to find the best arrangement. Cut a piece of strip board 8 rows wide and up to about 25mm long that will fit flat on the floor of the box. The strip board will act as a bus to connect to the header. I placed the...
Bend the pins on the header at a right angle. Drill 8 holes 1/16-inch (1.6mm) diameter in a line spaced 0.1-inch (2.54mm) on centers. Pass the pins through the holes with the header on the underside of the box.
