Waiting For A Letter? This IoT Mailbox Will Tell You Exactly When It Arrives.

Posted on by

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 …read more

[Mike Diamond] was tired of climbing down (and back up) 40 stairs to check his mailbox. He decided to create a mailbox alert using the ESP8266 to connect to his WiFi. The idea was simple: have the ESP8266 monitor when the mailbox flap opened using a magnet and a reed switch. As always, though, the devil is in the details. [Mike] got things working with a little help and shares not only the finished design but how he got there.

To handle the sending of e-mail, [Mike] used the Blynk app. You often think of Blynk as a way to build user …read more

Understanding the overhead in an Exchange mailbox database

Posted on by

It’s taken me a while to get around to mentioning the rather useful “Database Growth Reporting” script for Exchange 2010 and Exchange 2013 that was described on the EHLO blog in January.  My apologies for this lapse in service. All I can plead is that other stuff got in the way between now and then and that I never really had a chance to test the code out thoroughly, which is a prerequisite before commenting on software.
