I had some G120 modules lying around and some nice Newhaven 4.3" LCD’s so I decided to make a clock with them and have 2 displays. The first will show time and date and the second one various sensors that I have sending out MQTT packets.
The right hand display is just the first rough cut one and I want to make this prettier.
There is a RS21 WiFi module on the right hand display that is used to sync time and get the sensor data via MQTT.
I have used CANBUS to link the 2 displays so that I can send synced time to the clock display and also setup alarms etc. There is a small buzzer to do the alarm sound.
The panels are made by Schaeffer-AG in Germany and the text is printed rather than the normal engraving I go for. Just a test and it looks good.
The sides are made with red perspex which is quite dark so you can just see the insides.
The 2 USB ports are supposed to be on the back but I goofed with the footprint and they ended up sticking out the front. Makes programming easier with it assembled.
