Re: I don't understand the point of still using USB 2.0

Most often two USB ports are only used to connect a keyboard and a mouse anyway.

when will raspbian be 64 bits?
Raspbian Is 32-BIT so its compatible with previous PI's.

If you MUST have a 64-bit OS (although its slower, and uses more memory) use another OS, there are several that support 64-bit

Thank you for solving (I guess) the Scratch 3 problem I asked about Scratch for the RPI4, and got this comment: The online Scratch 3 runs pretty well.

Re: How to turn on a LED

a rookie mistake would be to insert the flatcable connector on the other (invisible in this picture) side, rotated 180 degrees. the brown-red wire pair should be near the pin-1 (left in most pictures of a PI) side, not on the right hand side (near the USB connectors). another rookie mistake would be...

Thats not a QR code, QR codes are easily recognizable by the three alignment squares in three corners of the square.
not every two dimensional barcodes are QR (Quick Recognition) codes.

Re: input activated by chainsaw))

That would work, but if you program the GPIO as an output, and the switch is closed a large current would flow, which destroys your PI, so I would also add a 330 Ohm resistor in series with the GPIO, like this. button_schem.png also again, the voltage the switch is connected to MUST BE 3V3, as show ...

Re: RetroPie in SEGA VMU and Kodi.

You can't "brick" a PI, nothing is stored in a PI, so if you change the SD-card the PI is "unbricked" again.

that is not to say that you cant damage the PI, I have written about the things that damage it in the "pitfalls sticky", but changing the memory split is not one of them.

Re: Soil sensor (2 nails) ads1115

NO! use the logic power supply of an RPI, which is 3V3, NOT 5V! otherwise you risk pulling the I2C lines to 5V (the board has pullups to the logic power of the board) which might damage the RPI. remember the first rule of the RPI, never allow any voltage more than 4V to reach a GPIO pin!!!! The RPI ...

Can you measure the state of charge of a rechargeable cell by measuring its weight? no, its unmeasurably small. at a zero point then 32 zero's then 91 kilogram per electron, (that is 0.0000000000000000000000000000000000091 Kg) even with a billion electrons it would still weigh nothing at all, just ...

Re: how heavy is raspbian ?

never knew that electrons have mass (have weight) but apparently they do. Mass of electron is 9.1×10^-31 kg while proton and neutron weighs almost similar ( 1.67×10^-27 kg). so if a flash cell with a "1" weighs more or less than one with a "0" depends on whether a "charged cell" (with more electrons...
