Raspberry pi zero of 1GB of RAM?

Hi.

I'm seeing that they sell a Raspberry Pi Zero with 1 GB of RAM, is that official? Because the Raspberry page says it is 512 MB.

Give me your opinion, please. That's true? Do you recommend buying it? Do you know a safer place to buy it?

No.

Not if you want it to continue working.
Is there a smaller alternative?

Cut Raspberry Circuit

Is it possible to cut the Raspberry Pi Zero W card?
I want to make it smaller by removing what I won't use (like the LCD).

It's possible?

Or fold it in two.

Hi.

I want to be able to control my Raspberry with my voice. I am trying to use Jasper, but I get many errors at the time of installation, I think it is discontinued.

Re: Raspberry motor controller

Actually the L298N only controls two DC motors at a time. For some reason they have put two motors on each output, but they will be both on/off at the same time. Most motor driver chips control two DC motors. Thank you very much for your answer. Is it possible to use two L298N cards and have 4 serv...

Raspberry motor controller

Hi.

Look at the min. 4:40 - https://youtu.be/X7tqmrf8tYI
I have seen that it is a widely used controller. My question is: does it only allow 4 motors to be controlled?
Do you recommend a better controller that supports more engines and better capacity?

Hi. I plan to sell a product that I am going to make with Raspberry Pi. My problem is that I can't think of anything for my clients to update it remotely (when I offer code improvements), something like an app that is linked to the raspberry and they start downloading. Do you know any open source? G...

Re: Motors for robots

Do you remember what Archimedes said about a fulcrum and the earth. In your case think "gears". That's right, but imagine that the servomotor is extremely small, because of friction it is physically impossible for a truck to, although in theory it is possible. However, if the servomotor is small an...

Do you know any open source robot arm that has image recognition and voice control?

Or just something that can help me in creating a robot arm, or some advice. I say it because I am new to Python and Raspberry.

Raspberry PI 4 vs Smartphone

Hello.

My question is: which is faster, an android Smartphone (for example, 6 GB RAM) or a Raspberry (4 GB RAM)?

I'm just judging it by RAM, but, maybe there is another component that I don't know. Maybe the processor is better, I honestly don't know.

Hello.

Is it possible to control a raspberry only with gestures read from the camera? It would be as an alternative to the mouse, click, go left, right, etc.
It is advisable?

I see you invented the screen both vertically and horizontally. You can see an example here: https://des.gbtcdn.com/uploads/pdm-desc ... 764635.jpg

Imagine that the screen is going to reflect on a glass.

With "Inverted" I mean that when the image is reflected on the glass, it looks as if I am looking directly at the screen.

It's possible?
