using the raspberry pico to drive the electronics for a parcel delivery vault.
Thaddy:
Yes, I indeed want to use FPC and I am capable of adapting the code for the pico if necessary.. The specialized latch/lock is a good idea. Your last remark is pretty much how I dreamt it. I will have a look on where to source a latch/lock solenoid.

It is probably not too much work to rebuild the latest Pico SDK though. FPC wifi capability also available via ESP8266 & ESP32.

Yep, Michael's excellent model does not cover wifi. I looked at doing so but the newer release of the Pico's C libraries are contain a very closely cross conected mess of modules and in the end, I found it easier to do what I needed using C :(

Another idea is to use a simple cheap sliding bolt and drive this with a small servo (requires PWM to position).

Hmm, I initially suggested a solenoid instead of a motor but did not consider a stepper to be honest. I reconsider, a stepper driving a small shaft probably would be easier mechanically. I have not used a stepper with a Pico but have done so, very easily, with an Arduino.

Hi Thaddy
Nice project, very interesting use of the 'pico', will you keep us posted in this thread?
I for one, am intrigued 8)
Happy fiddling... :D
Regards Benny

Another approach, far, far simpler. Seeing a plastic box in use, how about a reed switch in not obvious position, you hold a magnet near it, switch closes, it drives the solenoid/motor. Only you know where to hold the magnet, indeed, only you know you have a magnet in your hand.

The plasic box is merely a suggestion by AI, nothing to do with that! I asked for a metal box, and, yes I got some very retro cast-iron metal boxes too. Would be cool to combine that with a retro phone dialer disk.... (but that is for V2)
But it is an option ;)
I also asked on the Raspberry Pi pico forum.
