Solder up the AVR + regulator onto a perf board, according to the schematic. Include programming headers (MOSI / MISO / SCK / RESET) and a 6 pin breakout for the PS2 controller wires you soldered last step.The schematic for this is below:
Glue a 3xAAA battery holder to the outside of the case. Connect the power switch in series with the positive side of the battery. Re-assemble the case. You should now have a self contained unit with batteries on the outside and a switch....
PLEASE NOTE: Before you dive right in and assemble your Wave shield, there are a few things you will need to take note of: Make sure that you use the 'Stacking headers' on your wave shield. It will be in the middle of the stack so that...
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...
Now that the PSU is done, Arguably the most difficult part, the rest is pretty easy. There are two major components that need to be built now: The control circuit for the HV psu, and the Hand sensor.These are the last two critical custom...
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...
To get a good idea how we made the electrodes, you can read the project update entitled "The Hand Thingie". If you want to use the same sensing set up we used, this worked well. Any sort of Object that is fairly ergonomic and can have the...
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...
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...
