FINALLY, the schematic is available.
I will check it the coming days agin but it should be OK.
Next on the list is cleanup of the code, must needed...
Thank you for your patience...
I always wanted to make a so-called 'Gorgy' Clock. You see them often in music or TV studios. Now I could, so I bought a cheap clock at Ikea and ripped out the inside, making room for the electronics and display.
A commercial Gorgy clock and the Ikea clock I bought:
Because it was to be my bedside clock, I thought of adding some extra features such as an IR remote and barometer- humidity and temperature sensor because I love meteorology.
When I'm awake at night, I have something to look at: temperature (min/max), barometer trend of the last 24 hours and the air pressure change rate, which is a very good indication of pending bad weather.
Alarm clock function
I also would like to use the clock as an alarm clock with a blackbird sound to wake me up using an Adafruit sound card. But my lack of programming skills concerning the necessary menu structure was a stumbling block (so far).
Adjusting the time
Adjusting the time is sort of possible via the menu:
It is poorly implemented (for now), so what I did is assigned a button on the IR remote to set the seconds to zero when I press that button. If the seconds on the clock are <30, the minute stays the same and the seconds are reset to 0. When the seconds on the clock are >30, one minute is added and the seconds are reset to zero.
So with a accurate clock (on my phone), just before the '0' mark I press the button and the clock is synced. Then I'm good for a whole year because the temp compensated RTC is extremely accurate.
I just discovered the possibility to use a laser cutter at a local makerspace location: GREAT! So this way I could make the black acrylic mounting frame for the LED's and TFT display:
On top of that I also cut a piece of heavy weight black paper to cover the gaps around the TFT display. Then I cut a brown acrylic display to enhance the contrast of the LED's and make the gray 7 segment displays less noticeable.
On the small 1.8" TFT display, I now have 5 display options:
As a gimmick, I included a 'thermal comfort indicator' in the form of a traffic light.
When I'm awake at night and a storm is passing I can see the barometric pressure plunging and rising after the storm has passed. Better than looking at the ceiling.
