To control asual key box with an ESP over the cloud in the fablab of my university. As a server ILMO (https://github.com/moan0s/ILMO) is used. For the usage of the key tresor from wuerth it is neccesarry to modify it a bit. You have to remove the nose and replace it by the electromagnetic lock drawer. Also the locker pin at the door has to be replaced by the printed version.
The printed box covers the whole electronic stuff and also two LEDs and the RFID modul.
The circuit is made with fritzing. (https://fritzing.org/) The 3d parts are made with Solid Works Student.
