Have some PCB photos.

Nerd statistics:
- STM32 (STM32F103C8T6)
- USB Type C PD-chip HUSB238 (to get 12V)
- LDOs making 5V and 3.3V
- Level shifter to make the correct 25kHz 5V PWM signal for the fan
- Variable dummy load to keep power bank on (for low fan speeds)
- RGB LED to indicate power level

It‘s quite nice to be able to change the speed. Rave at full speed, or have conversations at low speed. Best of both worlds!

Step 4: Final installation. I asked my maker @equinoxkitty.bsky.social to add a pocket in the front neck for this, so that‘s where the controller and powerbank go!

Controller in action! Me cycling through all the available speeds.

Note there is no „off“ speed, you would just unplug the USB for that. This is to save battery, because then the powerbank can also go to sleep.

Cable to the fan goes through a printed TPU (rubber) strain relief/cable grip that should make this end quite durable as well.

Since this is a 12V fan, you do need a powerbank that can output that. (USB Type C Power Delivery).

Thankfully these are pretty common nowadays. Most powerbanks that support fast charging can output this voltage, but it is important to check.

The center piece of the build is this small controller I made.

It‘s permanently attached to the fan and can be powered with a USB Type C powerbank.

You select the speed you want with the buttons. Each speed has an associated color that lights up, so it‘s easy to remember what setting you liked.

Step 3: The fan itself, attached with velcro.
Hot glue to secure the wires from breaking off. A finger guard to precent chopping.

This is a SANYO DENKI 109P0412P3H013.
12V, 8700 rpm, 4-wire (with PWM - important), 40x40x28mm

I removed the tachometer wire, which is why you see only 3 wires.

Step 2: This 3D printed piece that provides a surface for the fan to be stuck on in the next step. It also angles the fan a bit down so the airstream hits both my nose and mouth area.

Step 1: Added velcro to the nose bridge of my suit here. (Self-adhesive strips)

Pro tip: use the soft side, or it gets scratchy inside :)

What‘s cooler than fursuiting? Doing it while staying cool yourself :)

I made this mod for my fursuit to add a fan, which is:
- variable speed, quickly selectable
- powered by USB Type C
- quite compact

I did a bunch of design work on the controller for this, so I wanted to share! (Thread)
