Description

On the Anet Board based printers, the hot-end fan is always on. The idea is to build a small board to automate the fan power.

Details

The idea of this project is to have a board that can be placed between power of the fan and the fan itself. It will then be triggering a mosfet when temperature reach 50°C (can be adapted in software).

First assembly

I've received few of the components (except DC converters) and started assembling the board.

It is alive!!!

There are few mistakes to take in count for future version:

1) GND vias are not linked to GND net

2) Few footprints are a bit small for hand soldering, it could have been a bit bigger

What I still want to do :

1) create a programming rig with pogo pins

2) create a test jig that can perform tests on devices for several hours

(I want to do this for fun and learn, it is of course overkill for this project ;) )
