The LILYGO T-Display 1.64 amoled has one of the sharpest displays I’ve ever used at 280x456 pixel resolution. Sadly no TFT_eSPI support though.

Drew each object using Figma and exported to Squareline Studio. The sun uses the rotate animation and the clouds use separate move on X axis animations. The graphics are copied from and Adafruit blog Lottie post because it looked so nice. #esp32 #arduino

Found this circuit idea on a Silicon Labs dev board schematic used to cut sensor i2c data & power pins for ultra low power draw. Will be perfect for my next #esp32 low power design.

It’s good that deer in Canada have listened are finally taking safety more seriously. reddit.com/r/nature/s/kK4…

Only ChatGPT was used to write this sketch. The first ask was, can you write an Arduino sketch using the TFT_eSPI library with a resolution of 280x240 to bounce a ball. Then add more balls, add gravity, have the balls different colors and bounce off each other…

It’s a little buggy but this sketch was created entirely using ChatGPT available at: github.com/mike-rankin/ES… #arduino #esp32 #chatgpt

Designed my first custom ESP32-C6 board today to experiment with thread sensors & Apple Home. This has a 1.69” lcd cap touch lcd on the other side and is always on powered by a usb-c phone charger. #esp32 #arduino

Size difference between the ESP32-S3 on the left and the smaller ESP32-C6 on the right. For when every millimetre of space matters. #esp32 #oshpark #arduino

Resized an animated gif and split it into 38 frames at 240x160 running on a custom ESP32-S3 board that plugs into a phone charger. Started listening to the audiobook ‘Doom Guy’ narrated by John Romero. #esp32 #arduino #squarelinestudio

Created this eink sensor board for a customer that had to be low power. As a brute force method I used quad switch TS3A4751 to disconnect the +5v boost power & data lines from the micro. Testing shows very good results. #esp32 #arduino #altium #jlcpcb

Liking the JPEGDEC Arduino library by Larry Bank that displays .mjpeg video files off of a microSD card. Full tutorial here: youtu.be/jYcxUgxz9ks?si… #arduino #esp32
