ethernet edition in July inspired by this nice video out on MAKE. This route has worked out much better, especially since we have a mailbox on our house.
I'm happy to say we have now been consistently using the Snail Mail Notifier since late October 2012. After a minor tweak to the code due to massive email spam, the setup has been working perfectly. We have it sitting on top of a pedestal sturdy cardboard box we picked up at a local craft store.
A snap action switch is installed in the mailbox. The wires run in to the house and are hooked up to the arduino just inside the door. When the mailbox is opened three things happen:
- A push notification is sent to the iOS app Prowl.
- Note that the avviso library does allow this to be configured with android as well
- An email is sent to Chris and I letting us know mail has arrived (thanks to some php code Chris whipped up)
- A green LED status light goes on (great visual cue for when neither of us have checked a device lately)
ethernet shield with the correct W5100 chipset for $14, this wireless solution was much cheaper.
Admittedly configuring the router was painful until I found this very helpful instructable (and specifically these wireless client configuration example). Now our Snail Mail Notifier is completely wireless!

- configure the arduino sketch to reset the counter for the next day automatically. Right now the device has to be manually reset each day. Since I pass right by it, hitting the reset button isn't a big deal, but eventually I'd like this automated.
- decoupage the box
- ethernet shield (common shield that uses W5100 chip)
- TP-Link TL-WR703N router, flashed with Open-WRT and configured as wireless client
- a snap action switch
- 10K resistor for the switch
- green LED
- wire (I had 22 gauge lying around)
