...Back to Projects:

The Pusher Board is an IoT project that does one thing - it pushes you a notification triggered by a digital input. Well, it's much more than that, but this is the inspiration. I wanted to design a WiFi board that essentially sleeps most of its life, but when that door switch, flood sensor, motion sensor, etc.. gets triggered, I just want a notification immediately on my phone. And that's about it... a perfect IoT device in the background doing its job.

Version 1

Very first prototype board

• Mostly through hole components for easy testing and assembly
• ESP8266 based (ESP-12S module)
• Wake on regular timer interval - set for 1hr during my testing.
• Wake on Digital Input - Normally Closed type contact, so works nicely with door sensors.
• Tested sleep current <1uA that's years and years of battery life.
• Max Battery Voltage is ~4.2VDC, so designed to be used with standard Lithium Batteries.
• Note: this board does require re-work in order to exercise all of the functionality. Please watch assembly videos below for detailed information

Here's a quick demo!

Pusher Board Sending Push Notifications with Pushbullet and hardware walkthrough

I'm using Pushbullet for the Notifications:  https://www.pushbullet.com  (~$40/yr for unlimited pushes - 500/mo for free version)
That's nice because you don't need to develop your own app or anything.  Just set up an account with them and you're good to go.  Go to settings, account, and API - generate your token and copy that whole thing into the code - should be something like o.xyz...

And where I found the Pushbullet API code:  https://steve0hh.github.io/2016/12/04/how-to-send-push-notifications-using-esp8266.html
 Update 7/28/17 I did have two instances where the board failed to go back to sleep after wake.  I had to unplug the battery to resolve

Soldering the board is pretty much the same as V1.
