If you’re waiting for a much sought-after letter, checking your mailbox every five minutes can be a roller-coaster of emotion — not to mention time-consuming. If you fall into this trap, Hackaday.io user [CuriosityGym] as whipped up a mailbox that will send off an email once the snail-mail arrives.
The project uses an Arduino Uno, an ESP 8266 wifi module, and an idIoTware shield board — making specific use of its RGB LED and light dependent resistor(LDR). Configuring the RGB LED on the idIoTware board to a steady white light sets the baseline for the LDR, and when a letter is dropped in the box, the change in brightness is registered by the LDR, triggering the Arduino to send off the email.

“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.

[Ruben van der Vleuten] wanted to get a look at the adventure a package experiences when shipped from one place to another. So he threw together this mishmash of components to record the experience. We certainly enjoyed watching the fast motion video found after the break. We wonder what the shipping agency thinks about this sort of thing?
Camera, digital storage, and battery technology have gotten to the point that it’s both cheap and easy to do this sort of surveillance. But there are a few logistical things that [Ruben] took into account to make this work quite well. First off, he need to hide the camera in a way that would ensure the package didn’t look suspicious. He ended up writing his name on the side of the box and boring a hole through one of the black letters which is smaller than a pea and very hard to spot. To make sure he wasn’t recording a ton of empty (dark) frames he also included electronics to sense motion. When the package is moving the video is always rolling. when not moving the hardware wakes for just 3 seconds every minute to shoot video.

[Mime] lives on one of the upper levels of an apartment complex. The mailboxes, being located at the ground floor can be somewhat inconvenient to check regularly. [Mime] decided to rig up a device to let him know when his mailbox had been accessed. He started with a wireless doorbell, thinking he could use the door side button inside his mailbox as a trigger with only some slight modification. On the receiver side, he wanted an LED to flash, letting him know that it was time to check his mail. One simple circuit and a self blinking LED later and the whole setup was finished. Great job [Mime]
