I designed this little housing to support another project. It holds an Adafruit Trinket and Maxbotix MaxSonar sensor. The top screws on with 2.5mm cap head machine screws. I tapped the holes; if you don't tap you'll probably want to use different screws. The hole in the side is for wiring. I'm happy with the outcome and maybe someday it'll save someone else a little time.

Would you be willing to share the programming code and wiring details for this project?
Trying to make something similar and running into issues having the EZ1 and Trinket taking to each other.

Hi, I'm pulling + and - for the sensor straight from the battery pack (4x Eneloop AA batteries with a power switch). PWM out from the sensor connects to pin #1 on the Trinket. Battery + and - also connect to Trinket battery connectors. Finally, Trinket pin 0 is for LED data, and pin 2 is LED clock (I'm using a DotStar strip that needs +, -, clock, data connections).

I have my source code linked off this project page: https://mikeymakesit.com/projects/Sonar-Race-Gate/
