this is a simple wind tunnel created by request from my son, for him to show at school.
I intend to make some force gauges to use test lift and drag in the future, but with the use of a Laser Line, you can visualise flow very well, especially when the fan is set very low.
you can also use an Arduino as i did to monitor RPM and change the speed instead of the Noctual PWM controller linked below.
this is designed to just push together, if you want it more permanent you can glue it together.
Additional Parts/Materials:
6mm Acrylic.
