A while ago i purchased a fingerprint reader module called dy50 or fpm10a on aliexpress. A PN532 RFID module has also been lying in the tray for some time. So i decided to build a combined fingerprint and RFID reading module with a self developed and self printed housing.
The controller inside is a wemos d1 mini (esp8266 wifi module on-board). On the controller is a tasmota version with fingerprint module driver from adafruit.
As soon as possible i will commit and push my changes on github I have published my code on github: https://github.com/dhumpf/Tasmota . The software is still in development, but the basic functions adding a fingerprint, deleting a fingerprint, send the fingerprint data over mqtt to the home controller (domoticz installation) works already.
The total printing time of the enclosure was about 7 hours on the 3D printer.
The 3d files will also be published soon I have published the files on thingiverse: https://www.thingiverse.com/thing:4362609.
But now some pictures of the whole thing:
