Amazon Dash Reboots Your Pi

We all know feature creep can be a problem in almost any project. A simple idea can often become unusable if a project’s scope isn’t clearly defined in the beginning. However, the opposite problem sometimes presents itself: forgetting to include a key feature. [Zach] had this problem when he built a Raspberry Pi magic mirror and forgot to build a physical reset/shutoff switch. Luckily he had a spare Amazon Dash button and re-purposed it for use with his Pi.

The Raspberry Pi doesn’t include its own on/off switch. Without installing one yourself, the only way to turn off the device (without access to the terminal) is to unplug it, which can easily corrupt data on the SD card. Since [Zach]’s mirror was already complete, he didn’t want to take the entire thing apart just to install a button. There’s already a whole host of applications for the Dash button, so with a little Node.js work on the Raspberry Pi he was able to configure a remote-reset button for his mirror.

This is a similar problem for most Raspberry Pi owners, so if you want to follow [Zach]’s work he has done a great job detailing his process on his project site. If you’re looking for other uses for these convenient network-enabled buttons, he also links to a Github site with lots of other projects. This pizza button is probably our favorite, though.

Make Your Mailman Nervous With a Wifi Enabled Mailbox

“It’s not a bomb,” the mailman whispered to himself as he reached for [atxguitarist]’s mailbox, giving a nervous glance at the small black box stuck to the side. “This is THAT house, it’s not a bomb. I’m sure it’s not a bomb,” he muttered as a cold bead of sweat ran down his neck. His hand approached slowly, shakily. The mailman gathered courage, then, in a single quick movement, opened the box. He sighed relief as nothing happened. Somewhere in [atxguitarist]’s house a recording wailed “You’ve got mail!”

The mailbox enhancement in question is a hacked Amazon Dash Button in a project box. When the door of the mailbox is opened, a magnetic reed switch simulates a button press on the Dash. The Dash transmodulates the signal into WiFi pixies which are received by a Raspberry Pi. The Pi’s sole purpose in life is to run a 24-line Python script that plays the famous sound from AOL’s mail software and sends a notification to his phone.

Aside from unnerving the mailman, it’s a cool hack and keeps you from slugging it out there in the cold or rain to witness an empty box.

Hack Corporate Overlords For Single Button Beer Delivery

[Brody Berson] is at it again, but this time he’s hacked the services floating in the aether around him to give him beer on demand. Finally the future we’ve been waiting for.

This hack is not as hacky as his first one, which, at the push of a button, could summon a bad driver straight to his house who would then give him pizza. The first one was done with a modified version of a button used to summon paper towels; because there’s nothing like needing paper towels RIGHT NOW, and then pushing a button to get them a few days later.

Apparently Amazon saw how practically no one was pushing the dish detergent button, but a lot of people were making scary mailboxes and magic pizza apps after ruthlessly scratching the branding off. So they shrugged and decided to sell the buttons as the newly branded (these get more hilarious when you don’t use the acronyms) Amazon, Amazon Web Services Internet of Things Button. Now your button can die along with the internet because Amazon is hosting your Raspberry Pi for a small fee, neat.

Anyway, [Brody] did some research on the best beer delivery services in his area, and went with one called Drizzly because they had a nice API. After integrating this system with Amazon’s, he can now push a button and minutes later, after subtracting some currencies from his account, a bad driver will show up and hand him beer.

Amazon Dash: Hack It to Run Your Own Code

The Amazon Dash is a $5 push-to-buy-cat-litter button which has excellent potential for repurposing, but you need to know what is going on inside first. [Tony Dicola] has the details in this excellent bare metal guide to the Dash. In this, he covers how to get inside the Dash and reprogram it to do something more interesting than buying cat litter.

He first cracks the device open, connecting a programmer, then building a toolchain to compile programs to run on. This isn’t for the faint-hearted because you are programming directly for a device that wasn’t really built for it, but [Tony] has posted examples and there are few tools to hold your hand on the way. There is a safety net, [Tony] provided details on how to reset the Amazon Dash Button if you manage to brick it.

We have seen some interesting hacks that repurpose the Dash to capture your child’s bowel movements by intercepting the device connecting to WiFi, but this guide takes it a step further. It allows you to run your own code, which turns this into a really low-cost and well-engineered all-in-one WiFi device. The missing piece is proof-of-concept code to run the WiFi module inside. If you’re working on that we’d love to hear about it!

Hacking the Amazon Dash Button to Record Whatever You Want

We’re still not too sure if the Amazon Dash button is a brilliant marketing and advertising ploy, or is just downright stupid. But what we do know, is for $5, it’s a lot of hackable tech that could be used for more… useful purposes. The big A sells these dash buttons for one purpose — you push the button and whichever product is assigned to it shows up on your doorstep in a few days. [Ted Benson] wanted them to do more than that so he turned a few dash buttons into a way of tracking his baby’s health!

Apparently, data acquisition of your baby’s wake-up times and poops is useful to identify health patterns. [Ted] tried using some phone apps to keep track of this stuff, but found it would be a lot easier if there was just a big button on the wall or something… which is where he got the idea to make use of the Amazon Dash button.

It’s actually really simple to do. Buy the dash button, do the setup with Amazon… but don’t do the final step: selecting the product you want to order. If you don’t select anything, you won’t order anything…

DIY iPhone Mount for a Volvo

[Seandavid010] recently purchased a 2004 Volvo. He really liked the car except for the fact that it was missing some more modern features. He didn’t come stock with any navigation system or Bluetooth capabilities. After adding Bluetooth functionality to the stock stereo himself, he realized he would need a secure location to place his iPhone. This would allow him to control the stereo or use the navigation functions with ease. He ended up building a custom iPhone mount in just a single afternoon.

The key to this project is that the Volvo has an empty pocket on the left side of the stereo. It’s an oddly shaped vertical pocket that doesn’t seem to have any real use. [Seandavid010] decided this would be the perfect place to mount his phone. The only problem was that he didn’t want to make any permanent changes to his car. This meant no drilling into the dash and no gluing.

[Seandavid010] started by lining the pocket with blue masking tape. He then added an additional lining of plastic wrap. All of this was to protect the dashboard from what was to come next. He filled about half of the pocket with epoxy putty. We’ve seen this stuff used before in a similar project. He left a small opening in the middle with a thick washer mounted perpendicular to the ground. The washer would provide a place for an off-the-shelf iPhone holder to mount onto. [Seandavid010] also placed a flat, wooden paint stirrer underneath the putty. This created a pocket that would allow him to route cables and adapters underneath this new mount.

After letting the epoxy putty cure for an hour, he removed the block from the pocket. The stick was then removed, and any gaps were filled in with putty. The whole block was trimmed and smooth down for a more streamlined look. Finally, it was painted over with some flat black spray paint to match the color of the dashboard. An aftermarket iPhone holder allows [Seandavid010] to mount his cell phone to this new bracket. The cell phone holder allows him to rotate the phone into portrait or landscape mode, and even is adjustable to accommodate different sized phones.

A very dash-ing iPad mini


The work which [Mark] did to mount this iPad mini in the dashboard of his Ford truck is commendable. It looks like it came from the factory this way, and the functionality matches that illusion.

He actually started the project before he had the iPad mini on hand. A PDF that mapped out the exact dimensions was used as a template for the layout and alteration. He took the stereo controls out of the original faceplate. That opening was made to fit the screen by cutting, adding putty, then sanding and finishing.

Since the bezel won’t let [Mark] get at any of the buttons on the iPad itself he picked up an external home button on eBay and mounted it just to the left of the screen. Inside the dashboard a docking connector is responsible for powering the tablet and connecting it to the sound system. There’s even a WiFi connection thanks to the MiFi system he mounted in the overhead console.
