To quote the Arduino website:
"Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments."
I got one a while ago and life has never been the same. Here is the official website for Arduino: http://www.arduino.cc/
There are a bunch of tutorials that show you how to build your own Arduino on a breadboard, called Hack-duinos or something similar. While these are handy, I prefer to use more solid electronic devices. So I build them with a home made PCB and solder all the components on there myself.
Some may say, "This task seems time consuming and a tad expensive... Why not just kerplunk the 30-some-odd bucks for an REAL Arduino?" Well, some of us enjoy the craziness of making something completely from scratch -- and in doing so, learning more about the device you are using.
This tutorial will take you through all the steps of making your own printed circuit board(PCB), building an Arduino or "DIY-Duino" and loading your own programs/sketches onto the board you have built.
Step 1: Materials List -- For All Steps
You will find detail on these materials throughout the specific steps of this instructable.
// ------- PCB MATERIALS LIST ------- //
Copper Board: 12" x 12"
You can buy a smaller board, if you want.
I buy the 12x12 because I use it for a lot of projects.
DIY-Duino Pattern sheet
Click here to download the Pattern file
You must use this file to ensure the proper resolution and size of the image.
High-quality photo paper with a glossy finish is the best to use.
Or copies from a place like Kinkos or Staples.
Fine grain sandpaper
To rough up the board and make it able to absorb the pattern better.
Common, houshold tape
For securing the pattern to the copper board
Piece of scrap cardboard
This will be your makeshift ironing board.
To put over your board before ironing.
Use one you don't mind being ruined.
Chances are, it will get funky.
To bathe your board in warm water after ironing.
Not necessary, but can be helpfull for peeling off transfer remnants.
//------- ETCHING MATERIALS LIST -------//
Jug of Muriatic Acid
You can get this at the hardware store.
Container of Laquor Remover
Removes the toner once the pattern is etched.
Also useful if you make mistakes on transfering your pattern.
You can remove the toner and try again.
You can get this at the hardware store
Container of Hydrogen Peroxide
Any Grocery Store
Standard kitchen paper towels
Use for the ironing, agitating the acid solution, and removing the toner with the lacquer remover
(2) Plastic containers
(1 for the acid mixture, one to rinse, one to bathe the PCB in hot water)
Acid disposal container
Size this, depending on how much you're using.
Pair of plastic dishwashing gloves
You can often find a better, more durable pair of gloves at the hardware store -- right near the muriatic acid oddly enough.
Breathing and eye protection.
Package of photo paper
I if you have access to a laser printer or laser copier. Otherwise, skip this.
1/4 Cup Measuring Cup
Use one that you don't mind being destroyed. Once you use this to measure out the Muriatic Acid, It should only be used for this purpose. NEVER use it to measure food again.
//------- DIY-DUINO COMPONENTS LIST -------//
(3) Little bits of wire
DIP Sockets Solder Tail - 28-Pin 0.3"
ATmega328 with Arduino Bootloader
Basic LED - Green (or whatever color tussles your vessel)
Resistor 330 Ohm 1/6th Watt PTH
-- 220 Ohm will work fine too if you have one
Resistor 10k Ohm 1/6th Watt PTH
Mini Push Button Switch
(2) Electrolytic Decoupling Capacitors - 10uF/25V
Voltage Regulator - 5V
(2) Capacitor Ceramic 0.1uF Crystal 16MHz
(2) Capacitor Ceramic 0.1uF
(3) Female Headers
You'll need to cut them, and it's a little trickey...
From Radio Shack or
//------- PROGRAMMING MATERIALS LIST -------//
FT232RL USB to Serial
4 short wires
4 longer wires
An LED-- to test if your upload was a success
//------- TOOLS LIST-------//
Dremel or Hacksaw
I suggest buying a Dremel or other rotary tool for this instructable, you will probably need a Dremel to drill the holes.
1/32" Drill bit
I don't know of one of these for a normal drill, neither did the lady at Lowes -- again... Dremel
Metal-cutting disc for Dremel
To cut out the copperboard
Desoldering braid -- for errors!
