On Saturday I picked up an Evil Mad Scientists Arduino clone, The Diavolino, from MadLab‘s little shop “Invent-ory” to use with my RS485 stuff. the Diavolino requires assembly yourself (official instructions).
Evil Mad Science – Diavolino Packaging
Evil Mad Science – Diavolino Parts
Diavolino Top Side
Diavolino Bottom Side – Note the non straite PCB track Layout
16 MHz Crystal and 18 pF Caps (marked with a black pen) installed (don’t do the switch first – its not as short as it looks).
1 k Ohm resistor installed
More Caps installed
0.1 uF Caps and 10 k resistor added
LED added, Programming header, I would also add the Switch now… I have mounted the ATmega328P in a DIP carrier
Using a sheild to hold the header pins straight to solder
Finished board.
Diavolino connected to my cheap FTDI (Future Technology Devices International) RS232 Programming Jobbie
The FTDI I bought was this one: RHX PL2303 USB To RS232 They are about £2.29 per. however where Windows 7 will grab the drivers from Windows Updates, there is a little bit more work to get it to be happy on a mac:
Connect the device to the Mac. Once connected click on the Apple icon and on ‘About This Mac’
Click on ‘System Report’
Click on ‘USB’ on the left and on the ‘USB-Serial Controller D’ If all is well you should be seeing something like this:
Install the drivers by following the instructions in the zip, reboot the computer, and plug in the FTDI board (copy wiring from above). load the Arduino IDE and select the board and serial
My Chosen Serial Port /dev/cu.usbserial
This is the Arduino Duemilanove w/ATmega 328
The first time you compile and upload the program you may get this error… all it means is you need to hit the restart button when the “compiling sketch” changes to “uploading…”
Thanks for this was at a mad labs workshop on sat, building lol shield, guy told me regarding uno would work, well it does kind of but didn’t realise one you built has no usb a real advantage. I went with straight uno and getting all sorts of problems…hopefully they still sell them. Just starting out so know nothing of ft di and using an old mac So appreciate your input here. Thanks
You should be able to pick up an official Arduino from Maplins. However you can also get ones like this one – http://skippy.org.uk/low-cost-duino/ from eBay or Amazon for not too much cash (requires a little work as detailed to work on Mac OS X).

Mitch Altman – https://m.flickr.com/#/photos/maltman23/ and Jimmy Rodgers – http://jimmieprodgers.com are both great guys to learn to solder with.
