433MHz transmitter

Every morning and every night I have to press a button on the remote control to open/close the blinds in my kitchen. In my constant efforts to have to do less things each day I feel the need to remove these two things.

Enter stage left a 433MHz transmitter that can be connected to [ you guessed it ] a Raspberry Pi and also my Flipper Zero to sniff the signal to send.

Sniffing the signal was the easy bit. I now have the hex code, and therefore the binary signal, to send the blinds up and down. Unfortunately it’s proving a bit tricky to get my Pi and transmitter to send a matching signal.

The Flipper Zero shows that it is receiving a radio transmission but it just doesn’t decode it correctly. It’s either that I don’t have the correct high/low timings for the signals…or that when I first hooked up the transmitter I attached the 5v line to the data input for the transmitter. Oooops.

I’ll keep beavering away and keep you, my dear single reader with the long hair and a talent for music, informed.

Wordle, you are truly a bastard

How many words are there in the english language that end with “ound” – quite a bloody few it would seem!
