Color Companion (Formerly IRL Color Picker) Devlog #2

What is this?
Ever seen a color and thought, I want that color! The Color Companion is a handheld device with a color sensor and display, which can give you the exact RGB and HEX values of anything for you!

New Stuff
Goodbye breadboard, hello case! I modeled an enclosure for the esp32 devboard, TCS34725 color sensor, and the SSD1306 oled display, along with a little toggle button for holding the color on the display.

Also, the color sensor has a shroud which seals itself out from ambient light, and includes a little divider between the integrated LED and the sensor itself. This way, the sensor only receives light reflected from the object, not straight from the LED.

Challenges

• While I originally intended it to have a built in battery, that would end up having to double the components (Battery, battery charger module, boost converter to get 5V), and also make the device too big. So I had to scrap it :(
• When I was building the mount for the display, I thought it would be easy. Just pop in four mounting holes for the screen, screw in the M3 bolts, and done. But disaster struck, The mounting holes for the display were M2 (A whole mm smaller than M3)! And because I didn’t have M2 bolts, I had to come up with a weird mounting solution. (Silver lining, I only need 2 bolts instead of 4 using my mount)

What now?

• Wire it up!
• Add HEX color values to the display
• Make the case round so it feels good to hold
