Re: Pi Zero W + Zerocam + Official case - is it really the wrong way round?

The official Pi foundation camera mounts the right way up. I would say the case was designed with that camera in mind. Anything else will be hit or miss, miss in your case. Thats the way it goes some times.

Re: USB HUB HAT not working

If thats just a pass through stacking header on the HUB board, soldering is not the issue. Thats what it looks like to me? If all that is on that board is a USB hub all that is being used on the GPIO is maybe +5v and ground, and if you had those shorted out the Pi wouldn't work. I see the PWR LED li...

Re: Camera Ribbon Cable - twisting problems

I have the Pimoroni Full Pan Tilt kit. My camera is mounted upside down, ribbon cable exits out the top. I just rotate the image 180 in Motion Eye to make it right side up again. I also swapped out the stock 6 inch cable for an 8 inch cable, no worries of it kinking etc when paned or tilted fully.

Re: Raspberry Pi as security camera

There is a Pi 4 version of Motion Eye. I haven't run it on my Pi 4 yet though. I'm using mostly 3A+'s. The latest release has support in it for Pimoroni's Pan Tilt Hat, of which I have one. It was a pain to setup but I got it working. Fully usable via the WEB GUI interface. I'm toying with getting a...

Re: Raspberry Pi <-> Arduino Pro Mini HAT PCB design.

I can't help with building the prototype boards, but have a look at this, it "might" be better suited to what your doing. You'll have to decide if it makes things easier or harder. ;)
It's a proto hat designed for the Raspberry Pi.

Re: Rpi4 On/Off Switch

I did it to my fan shim. The fan not turning off kind of bugged me. The button on the fan shim grounds GPIO 3 when pressed and can be used to turn your Pi on off. Its what I'm using for my on off button.

Re: Rpi4 On/Off Switch

One way to stop the fan on shut down is to wire a 10 K resistor between the fan control pin BCM 18, physical pin 12, and ground. It will act as a pull down resistor and turn the fan off when Raspbian shuts down. Auto control will still work once Raspbian boots up and the daemon starts. It will turn ...

Thin wires is not the way to go, you want 18 AWG or thicker wires to prevent excessive voltage drop across them.

Dental floss can also be used to remove the heat sink. Just stretch it between the heatsink and SOC, and pull it back and forth is a sawing motion.
