Here's next Tuesday's video, early for Patrons, his one goes out publicly on Tuesday 22nd.

This is a project I've been thinking about for a while, although it turned out to be a bit more tricky than my original plan - at least if I wanted the project to be affordable.  It helped me get into some Linux/Pi/Python projects though, and I have another one coming up in a couple of weeks.

DIY IoT E-PAPER Message Board

Get your first 10 PCBs for free at https://www.pcbway.com/ This is a project I've been wanting to build for some time - it's a message board for your home or business which can be updated from anywhere! The Message Board uses E-Paper which is very low power and only uses power when it updates. Combining this with the Google Docs API and Google Developer Console, using a Raspberry Pi, it's possible to make a message board that polls a Google Sheet and updates when there's new data.

Nice idea James. It's a shame e-ink displays are still so expensive compared to lcds.

Nice invention James! Someone should come up with an MQTT version, so that it updates instantaneously when the google doc is edited.

Since you mention a few times about the desired power efficiency of the e-paper display, perhaps it would be a good place to put in mention of methods of putting the Pi into a reduced power mode? Or using a different controller that uses less power than a Pi? Something like an ESP-8266 or ESP32 with built-in WiFi and deep-sleep states? It looked like the display's firmware page you showed supported a variety of boards? If nothing else, looks like a great use for a Pi Zero-W, the single-core should run with a lot less draw than a Pi 2 other "b" size boards with their more robust configurations. As is, seems you mention power-savings, but then don't attack it very seriously -- I know you can't fit everything in these quick little videos, but would be nice to deepen it a bit even if just in commentary.

Shad beat me to suggesting the ESP32 over the Pi. Any chance of you doing another video using the ESP32?

EPS32 is something I need to do a lot more with, it's another thing I've never used in a project. This is only the second thing ever to have a Pi in it!

The ESP8266 and ESP32 are both much better supported in your familiar Arduino IDE now. and the a large number of libraries are verified/adapted to work as well.

One of my motivations is trying to learn Linux stuff so I can do more intelligent robots, but I'll take a look - it's good to increase my 'building blocks'.
