Now that you have gotten some of the parts, and hopefully stocked your parts bins and caused some carnage in the process, we are ready to proceed. This is the end goal of this hullabaloo:You will wind two large inductors using the cores you salvaged...
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...
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...
Start drawing on Processing First lets create a code on Processing, which lets you draw freehand on the computer.Download Processing from https://www.processing.org/download/ .Here is the processing code:int prevX=mouseX, prevY=mouseY; //to record previous...
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...
Power to Servo motor So, we've written the code. Now start all wiring stuff:We have two options:Give 5V to servo motor from Arduino.Here, you can connect the servo motor ( attach a small fan to the motor ) to Arduino Uno. Servo motor has 3 wires: Connect...
Hack a mouse (optional) Open the casing of the mouse, and remove the scroll roller.Now, you should have space to place the servo motor like in the picture.To paste servo motor on the mouse board, use a glue gun or double sided tape.Now, there should...
Notes about tools and materials used:ProPoxy 20 is awesome stuff. When making the brass tube pivots for the shoulder rocket pods it was easiest to glue the brass tube to the servo casing with superglue ( I use Gorilla glue with a spray accelerator) and...
Solder LEDs, resistors etc onto a bit of veroboard. I used a female PCB header for plugging in the battery so that I didn't have to route long cables around the frame. Leave some length on the LED pins so that they stand up a bit from the veroboard
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 pipe into ring, bisect lengthwise into rings of halfpipe.Sandwich both sheets between rings.Drill holes equally spaced through sandwich.Apply ring of water seal between plexiglass, bolt, and inflate.If necessary, allow seal to dry.Deflate and inject...
Effective Bardware Based Stepper Motor ControlIn my quest to derive a robot control scheme from scratch, I've been working to figure out how to control a stepper motor. Stepper motors are great because they're cheap, relatively simple to control,...
Through Hole Technology (THT) versionThis is how I built the Through Hole Technology version Make a double-sided fibre glass PCB (see front- and back- PDF files below). There are several ways to do this. The way I do it is to print the front and back...
Use epoxy to glue the tower to the potentiometer casing. If using a wind sensor solder long wires to the V+, GND and OUT pins of the wind sensor. Seat it in the gap it magically fits perfectly into as shown below. Tidy your cables! I pleated mine and...
