How to build your very own Amazon Dash

Don't have an invite? Don't worry, open source has you covered with Oscar, a Raspberry Pi and commodity USB Barcode scanners. I've had a go at setting it up, and it's passed the wife test with flying colours.

With Amazon Dash, I like the voice component so it'd be interesting to use the voice API to add in items to Trello/etc.

I got Oscar, a barcode scanning shopping list app working!

Tada:

I've hacked it a little bit to add Coles online/Woolworths online support.

There  needs to be a better way to add multiple different items to a cart via the woolworths/coles UI, but shopping is now a matter of clicks from a list assembled during the week.

Needs more refactoring to add different providers via configuration; and I've removed the description rules - I found them to be hopeless; matching anything with the word 'milk' as 'milk'.

I also want to point at different barcode providers, and possible make a once click 'export all my barcodes and share' capability, so one new barcode is everyone's new barcode entry; but that'll come later.
