Thing1 and Thing211 Feb 2018 -
With smartphones in everyone’s pockets these days we have many ways to communicate but I wanted to get back to basics. I essentially recreated the telegraph here with one button and one haptic buzzer. You press the button on Thing 1 and Thing 2 vibrates and vice-versa. The whole thing fits in the palm of your hand and you can send and receive messages discretely, without having to look at anything. I did add an RGB LED for system status information.
These connect to each other using wifi so they need to be within range of each other. I could also program it to bounce up to a server and you could communicate across the globe. I had hoped to use morse code but the timing would need to be improved to capture the nuances of each person’s handle.
I used this as an opportunity to play with Circuit Python which works pretty well on these little feather boards. For my next project I’ll buy a board specifically designed for Circuit Python so I can access more of the features.
