Laser cut case for HC-SR04 Ultrasonic Sonar Sensor

This is part of a bigger project we’re working on for the Center for Artistic Activism. Everything is cut from 1/8 acrylic with room for wires out the bottom and a hole where you can attach a 1/4 tripod mount (you’ll need a nut). Otherwise it’s all pressure fit – no hardware needed.

This is designed around the HC-SR04 sold by SparkFun but we made adjustments to fit other sensors.

This was re-drafted through a few iterations in the SUNY Purchase New Media Fab Lab. Thanks to C4AA Resident Artist Iris Li Zihan.

Notes:

I used 1/8 in acrylic, but the precise thickness varies from sheet to sheet and within each sheet, so you’ll want to make some adjustments.

There are 6 layers that make up the case around the sensor. They are numbered front to back. Once you have the 6 layers cut, measure the thickness of one piece and the thickness of all 6 layers with some calipers. Use those measurements to make adjustments to the thickness of the “mortises” on the TOP and BOTTOM pieces and the overall distance between their outside edges.
