Compounds that don't conduct electricity are essential in many cases. Perhaps one can get away with sparing amounts of such things under a Pi heatsink but I would not want to be slopping conductive gloop over the board. Best stay away from most thermal paste/grease then, most of the better ones are...

... - power the Pi via the GPIO header, 5v pin/s and ground, or potentially the PoE header, if it can be leveraged for such use. The PoE header doesn't carry 5v - it takes power from the ethernet socket and passes it to the PoE HAT, which then powers the Pi through the GPIO header. Ah right, I misu...

Step one: buy USB-C cable, commercial one. Step two: cut cable Step three: Identify which of the dozens of wires inside are 5v, ground and possibly D+, D- if you plan to use gadget mode. Step four: clumsily attempt to connect the wires to your power supply Step five: fail miserably and just take the...

Jb weld has decent thermal properties, but do not get it anywhere except on the top of the CPU (it contains iron, so can very easily create short circuits) Also note that if you mount your Pi on its edge, and a large heatsink has been "JB welded" in place with nothing else securing it, the weight co...

I'm going to assume that of the nine tenants, only you are supposed to be connecting to this router?

If you have such a large video collection, its more efficient/cheap to spread it over *several* SD-cards.

And a better idea in general.
Should you lose one of the cards, you don't lose your entire collection.

A keyboard and mouse take next to no R&D, so it's simply a case of produce sell and profit, but this suggestion is different, it would require research and budget.

Somebody has done a neat review/comparison on the newly released ice tower cooler linked earlier in the thread

While not particularly recommended, not every charger is terrible. I've been powering my Pi4b via both the official Pi3 power supply and a random high quality 4.8A (2x2.4A) usb wall wart, with micro usb to usb c adaptor. In both cases, I've yet to see an undervolt warning. Granted, my use so far has...

Local online retailers seem to want about eighty cents per gigabyte for them. In comparison, a standard 1TB HDD will set you back five cents per gigabyte, getting cheaper as you scale up with 4TB costing just 2.5 cents/gb!

Pi is powered by a 2.4A USB. I don't know what that means for my LEDs but I am sure I'll find out.

It means you have 12W less resistances to power both a Pi0W (~150mA, ~0.75W) and your LEDs, assuming the power supply is accurately providing 2.4A at 5v

A decent and capable USB to SATA bridge would probably be of most benefit to people.

Of course, but is it something the raspberry pi foundation should be focusing on?

Imperf3kt

And the question itself makes no sense, they're all at the same price... Ah well, maybe someone will want to expound on the compared TCO of Pi3 and Pi4, including energy and accessories costs... :D No, they're not really, at least not once you factor in necessary accessories. But that depends on on...

This isn't likely to happen.

I'd instead ask a 3rd party to begin a kickstarter campaign or similar.

Thank you everyone for the great replies! I have a 128gb Evo in my 3 B+ and it works well, I've tried a few other 64gb and 128gb cards and they fail to boot the Pi. I can't wait to get my Pi4 when the 4gb ones ship in August. As always, when buying large storage media, you should always perform a t...

Imperf3kt

That's contrary to other replies from SanDisk I've read where the A# series was the recommended storage device for a Raspberry Pi.

Currently, tests performed by forum members point to A1 being the best card to use with A2 potentially performing worse due to requiring specialised peripherals.

Forgot to mention to check that the microHDMI was fully inserted. When I first plugged mine in, it felt like it was all the way in, but wasn't, I kept pushing and then it clicked in.

You don't mean a pattern of four flashes, do you?

From the description of what it actually is, I suspect a light touch with a fine file would clean it up nicely. I second this. My Pi4b came with a rather rough edge (I stabbed myself with mine) Just rub it back with something flat to break loose any large burrs and then hit it (gently) with some fi...

From your description, you have constructed an explosive / fire.
This is how I interpret your description

Please post images of your circuit and any additional info about it, nobody here can help without it.

What RPi model you are using?

most RPi Boards have audio jacks where you can connect any audio amp

The OP doesn't want audio playback, they want to generate tones and buzzes etc.

The only program I install on top of a Raspbian desktop is renpy.
Unfortunately the one in the repos is very outdated / experimental, so I must compile it from source myself.

Raspbian has everything else I need.

A photo and perhaps description would be better.
In that video, at the 50 second mark, I see no defect.

As I have answered this on similar topics you can power the motor directly from RPi's 5v one speed, one direction, and one time only! after that your RPi is K.I.A or R.i.P. What kills the Pi? As far as I see, you are merely connecting a motor ditectly to a current source. If the motor draws too muc...
