The box

Since the circuit is almost ready I started to think about the box. I do not want to send money on it, so I looked around my garbage heap. I found an old zip drive. Earlier I thought I will sell it on Ebay. Yes, yes it was working. Well just was RIP. I checked on Ebay, there are plenty of them for sale and even if they sell they worth about 5-8$ so it does not worth the effort for me.

I disassembled the box. Well it is not the best for this project, since it is closing with clips and not screws but it was free so I can live with that. I tried my board into it and found that I have to cut a couple of centimeters from the end of the board.

Here are some pictures about the box and the cut board:

Now the board is shorter

As you can see I cut two holes on the side of the box. They are for the external power connector and usb connector of the arduino. I still have to cut a hole for the LCD and drill some holes for the potentiometers and buttons.

I also assembled connectors to the back panel of the box:

I soldered jumper cables to the connectors. Two connector is connected to a single jumper cable. The second pins of each connector are connected together and the will be connected to the ground. I also use a jumper cable for that.
