About a year ago, I wrote about Amazon Dash - it's the dedicated "button" that orders products when you press it. (http://mark-amos.blogspot.com/2015/07/interesting-device-probably-overkill.html)
It's really kind of cool for things like laundry detergent, or other consumables that you might otherwise forget to put on your shopping list.
They've now released a programmable version that you can hook up to devices in your Amazon account. I.e. instead of ordering a product when you press it, you can configure it to do anything that you can do from AWS.
For example, you could connect it to a garage door opener or home security system. You could start/stop or launch computing resources on AWS. You could start and stop apps or otherwise initiate action using Lambda or SES or other AWS services.
They're selling them for $19.95, but apparently they've gone like hotcakes and no word when there will be more. They're the hottest thing since the Raspberry Pi!
