Auto-start Fan for FPV drone (bench work)

A compact solution to avoid VTX to go hot while working on the bench! (yes DJI owners you know what I am talking about)

How it works:

• The fan is from an old computer
• A 5v to 12volt booster provide the juice
• A small push button is under the plate…when you place your drone on top..it starts
• Red light is to show power is on
• Green light is to show that the fan is going

How to print:

• PLA - 15% infill - print in place - no support

What you need:

• 1 x 12V fan (80mm)
• 1 X 5v to 12 volt booster provide the juice
• 1 X push button (arduino like buttons)
• 1 X USB connector (if your booster doesn't have one)
• 2 X LEDS
• 2 X 220 ohms resistors for the LED
• 4 x M3 bolts (20mm) (for the top plate)
• 4 X locnuts for the top plate
• 4 x M3 bolts (16mm) for the bottom plate
• 4 x M3 nuts for the bottom plate
• Glue gun to hold the electronic in place

Advice:

• use glue gun to hold the button on top of the fan
• electronic box and bottom plate can be glued using the rectangle hole
• the top plate sits on the button, don't tighten up the screws too much
