Here’s something fun: Your Next Desk Toy Should Be a Hackable Robot. This “DeskBuddy” is basically a ESP32-C3 Super Mini microcontroller with a 1.3-inch OLED display. I tried to order one, just for fun, but it seems they only ship to India.

Interlude #11: Playing with WeAct Studio Epaper Modules on ESP32-C3 MCU | In The Lab With Jay Jay
This post is part of my video blog and you can find more information about this video over here.

In this video we play around with the 2.13″ and 2.9″ WeAct Studio Epaper Modules available here: WeAct 2.9” 2.13″ 2.9 2.13 Inch Epaper Module E-paper E-Ink EInk Display Screen SPI Black-White Black-White-Red.
As I mention in the video I was having a hard time getting good solder joints from my Horusdy Soldering Station. This was annoying me so much that I went and purchased a new soldering iron! My new iron is an Metcal PS-900 Soldering Station and I love it! This is what a soldering iron should be!
We use the Arduino IDE and the sample code from WeAct Studio but we don’t successfully load content into our Epaper Module.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to and the Rigol PLA2216 Logic Probe to wire up a Logic Analyzer to instrument out circuit, but we don’t follow through with that in the end. We run out of time. We will try again another day.

Debugging WeAct Studio Epaper Modules
I’m trying to get my WeAct Studio Epaper Modules to work on my WeAct Studio ESP32-C3FH4 microcontroller. I’ve made some progress, but it’s not working yet.
