Hi

I'm really new to Arduino and so far I have been only experimenting. After lurking around I want to start on my first project. I want to build a little sampler. It should play back audio files when you press a button. For this I will be using a Duemilenove and a Wave Shielf from Ladyada with a bunch of buttons. I also want to use an LCD to select kit's and load files from the SD card. For the LCD I chose I2CLCDextraIO because it only uses up 2 pins.

The Wave shield plays back 22khz 12 bit wav files and should be fast enough. It also has a volume rocker and an SD card slot on it.

The biggest trouble I have right now is the enclosure. I have no idea how to make one with the proper cuts and mount points for the hardware.

Anyway, I just wanted to post this to say hi and maybe you guys might have some good advice for me :)

The simplest way is to take your bits down to Maplin or Radio Shack or wherever and pick up an enclosure from there, seeing what will fit.

Buttons, easy - just drill them. The LCD and slots are a bit more interesting, but you could just use a Dremel or something similar.  If it has to look perfect, buy a few enclosures - it won't work out correctly the first time you try it. God knows I have made some horribly wonky holes!

I should really get a dremel...

My current method for non-circular holes in plastic enclosures is to cut inside the dimensions with a coping saw, then use a utility knife to cut away to the correct size, checking constantly as I shave off bits of plastic.  Probably not the most efficient method...

Hi

Thanks for the quick answers!

Can you suggest a dremel that is good for this purpose? I see a lot of them and I don't really know which one I need.

Another concern for me is how you plan for inside mounts and such? I mean how can you mount for example button breakouts so they won't break? Also the Arduino?

Thanks,

Ivan

Not sure about what dremel, I'd have a look around. For the arduino you could put some holes through and mount it with standoffs.
