Re: Pi 4 won't overclock past 1.75GHz

There is never any guarantee that any processor chip can be clocked higher than specified. For the BCM2711, that's 1.5GHz. Be happy with what you've got. If you're not happy, buy another Pi4B to see if that will go higher. In any case, it's not a defect.

Re: Using samsung fast charge for RPI3 B+

While that device *might* successfully power a Pi3B+, it is actually below the power specification for the Pi3B+: 2.5A @ 5v. If you let us know what country you're in, people might be able to point to a source for the official RPF PSU accessible to you.

Raspberry Pi Model B. About 3 versions from the beginning, as it doesn't have any remaining sign of the USB current limiting polyfuses.

Heres something to consider, the wattage.

A Pi zero uses what, 3 - 5 watts on average?
Getting a Pi0 to draw 1A would take some doing. What would you have connected to it? Personal experience is that a Pi0 with an attached 3.5" LCD panel draws a bit under 200mA, or just under 1W.

Re: Rpi 3B+: how cold can it still opperate?

I think someone has had an original RPi1B down to temps lower than -40°F (which is, curiously, -40°C). Unless things are different 15,000km away, -40°F is 4.4^°C in Australia. I recall slmebody using a Pi in Antarctica just fine. Also there was some project at CERN where the Pi was used in up to -2...

what about creating new subcategories under "Other projects"?
E.g. "Seismology" or other?

Re: VGA Monitor issues

The very first thing you should do is to check the monitor very carefully to see if it has a DVI connector. If it does, get an HDMI to DVI cable, or--if you're using a Pi4B--an HDMI to DVI adapter to go with the RPF microHDMI to HDMI cable. If it *doesn't* have a DVI connector, spend $20 and get a u...

Re: How to hook a receiver to a Raspberry Pi

Yes...you should be able to do that, but be absolutely sure that the 12v output from your device doesn't get to the Pi. Use a level shifter and/or optoisolators to protect the Pi from what it would consider to be high voltage.

Re: Electricity question

Data rates are not particularly related to power consumption. What you need to determine is the power draw 'at the wall'.
