Handheld EDF

thingiverse

HI! I got a 75mm EDF and ESC from a friend and wanted to use it for something. As I tested it in a workbench with an Arduino for a PWM signal, I really wanted to show my friends and colleagues its power. Thing is, it wasn't portable. A problem with a creative solution. I printed it in PETG so it will be stronger and easier fit together. It will probably be easier to print in PLA though. Wiring: Electronics parts I used: Arduino, XT60 Connectors, male-male Dupont wire, 5K potentiometer, Mini 5V DC-DC step down converter, PETG filament, ESC, and the EDF. I used the standard Arduino example to create a PWM signal. I wired straight into the ESC - the ESC is hidden in the handle, but it probably should have cooling; I've never used it long enough for it to be a problem. I used a 5K ohm potentiometer to the A1 pin on the Arduino and pin 9 to the ESC. The 5V and GND came from the step down converter and feed the Arduino and ESC. Other Info: The bottom EDF holder is not needed. If you have any tips or comments, don't be shy! If you found this useful, please donate what you think it's worth to my PayPal.me. Help cover the time of design. Thanks, enjoy, and don't die!
