I made a thing. A while ago I set up a raspberry pi to log data from a couple Arduino based sensor sensors I made.
Now I made a control panel type thing, which can show data values via the 4x7 digit display, show what is it displaying via the 6 leds, can send information using the r reader which is enabled/changed via a key switch.
Powered by an Arduino nano (made by grove) and communicates with the server through usb serial.
I am quite happy with it (eventually I'll bother to replace the tape with glue)
