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,...
First, here is the block diagram:You'll note that there are two relays in this circuit. These are used to connect the HV output to the hand electrode, and turn on the 12V supply to the Amp and HV power supply. You can spider wire them in...
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...
The image tag above tricks the user's browser into requesting http://hackaday.io/project/847/event/skull, which gives a skull to this project.Edit: I wasn't planning on this getting as much attention as it did. I've removed the offending image tag so...
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...
Spend some time on your LED and battery selection. These are the two most expensive items, and of course the most important.In my case I'm trying to light a volleyball court. The light I'm considering is available in 30º spread or 60º spread....
Optional (see #6 too, option of hard or soft enclosure): Use a 12" piece of 3" clear diameter heat shrink tubing to cover the board, the cut out the USB-mini connector with an X-acto knife, and mount rubber bumpers such as Digikey part # SJ5748-0-ND...
The first step to a good coffee brewing robot is to figure out how to brew good coffee. I've got some tips and tricks to brewing good coffee in the project logs ("A Dive Into the World of Coffee"), so I'll get directly into how I achieve good, full bodied...
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...
After reminiscing about my audio recording gear, I started thinking about a stand that I had purchased with the express idea of mounting the BR-900CD onto. It was a heavy duty music stand that I had picked up on sale for 20 dollars. After I got it home,...
