Hi folks

We all want a cheap and easy arduino to play with, so most of us want to build it to save money or to put in pet projects.
I've spent hours online looking for a simple and easy one and in the end this is what i ended up with.
Most of this instructable is from this site >> http://fritzing.org/projects/diy-arduino/ << and i do thank them alot for what they put up.

Right let's get started shall we.

Some soldering skills are needed.

Material list for this Instructable:

1 Atmega 16 or 328p (i used a 328p)
2 Ceramic capacitors 22pF
1 Crystal 16Mhz
1 Pcb
1 Resistor 10k 1/4w
5 Pieces of wire
1 28 DIP socket
1 7805 transistor
2 10uF/25V capacitor
1 9v battery connector
1 9v battery
1 Strip of female header pins
1 Minty box (i used a box from logitech that came with my wireless mouse)
Soldering tin
Some glue (not important)

Tools list:

Soldering iron
Drill for the dremel
Cutting discs for the dremel

Step 1:

Step 2:

Right, start by cutting your pcb so it fits into the box that holds it and place the DIP socket where you want it, and solder it in place so you have a point of reference. Next add in the components needed where you find some room for them. (crystal, capacitors and resistor)
Sorry for the lack of photos here but my phone ran out of power.
Move on to the wires and put them in the correct spot.
Add in the female header pins and solder them to the DIP.
And then solder the 9v connector in place. (remember to make a hole in the box you are using and thread the wires through it first)
Next, take the dremel and cut some slots in the lid of the box you are using.  (the female header pins and IC goes through them)
I added some padding in the bottom of the box to avoid short circuits.
You could use a label maker to add the pin outs so it's easy to find.
Or download these, compliments of Adafruit.

Step 3:

I forgot to say to begin with that you need a voltage regulator to run with a 9v battery, so to to fix this use a 7805 transistor and 2 capacitors before you connect the 9v to the GND and VCC on the Atmega. If you do not have a 7805 transistor you can use a usb cable.

You should be done by now.


Now then if someone figures out how to add a usb connection to this without using a FTDI please let me know.
<p>Excuse me, but the 7805 is not a transistor, it's a voltage regulator.</p>
Will it perform the same as Arduino UNO original
Would you please show how to make the voltage regulator using the 7805 transistor and capacitors. Thanks
I used a solderless breadboard and I just cut my usb cable so I can plug the wires into the spots that the FTDI would have gone into, if that makes sense.
Kinda. I'll just use a solderless bread board for mine. With the uploading to a normal arduino board, you plug in the cable (USB end in the computer), and upload the sketch. There is no plug on this board, so ow would you upload to it? You said 'swap ic's', I'm not what that means.
In step 2, picture four: Is that solder? The picture is blurry, so it's hard to tell how it should be applied. Also, upon completion, how would one go about uploading code to it? I assume it has 32K flash memory and 2k SRAM.
Hi, and if it is in the picture i am looking at yes that would be the pinouts where i set the female header pins. to upload a code you would need either a arduino or a FTDI. hope it helps (the arduino is just so you can swap ic's to program the one you just built)
I like it! did you space the header pins out so that this can be used with shields?
Thanks =) no not on this one, this one is meant for a 4x4x4 led cube. I am working on a new one for a robot arm, (just waiting for my 3D printer to get here) and one that i need to connect a LCD, and a temperature sensor to witch is going to have a shield.
