DIY: OLED 'unread email' and 'stereo volume level' display
More of my IoT hacking ;)
I'm using a 128x64 OLED $10 display (with u8lib), an arduino and an xbee to listen to 'beacons' that another xbee transmits periodically.
One message type is date/time and another is 'unread email count' from a python IMAP mail count fetcher I wrote. That runs on a spare linux box (rasp pi, etc) and it sends out ascii lines over the xbee transport every so often. A third is a volume display for my audio system.
New feature: when the preamp volume changes, this device gets an xbee update and changes the icon to a speaker and shows the formated dB (decibel) volume level.
There is also an alarm clock icon for when count-down alarms are set (not shown on this photo series).
Will have to plan on some cute little box for this, later on.
It looks like I finally was able to capture something close to the true color of this 'blue' display. Have to set the EV back quite a bit, of course.
