I notice one of my postings was included. I hope I did not cause offence in some way.


On another matter, it seems that the Raspberry Pi Pico Pin 25 (led) works oppositely to all the other pins. Very strange. This is my solution to the issue of the Morse being wrong....

def LightUp(Time):
    led.value(1)
    SkySend.value(0)
    buzzer.value(0)
    utime.sleep(Time)
    led.value(0)
    SkySend.value(1)
    buzzer.value(1)   
    utime.sleep(InterCharSpace)

I simply flipped my zeroes to ones and vice versa. Simple and effective but very unsatisfying because I have to work around what I would identify as a bug.

Onward with the next project or minor changes to the current project. I could replace the noisy relays with transistors and triacs. 

The next project will take two electric motors - both geared and 4 CDS cells and keep the cells aimed perfectly at the sun in order to track the sun while keeping a magnifying glass aimed at the sun. I'll try to focus that on a coin and see if it's possible to melt the coin.
