WD SSD in an external Inatek case

Heads up. I have been using a WD SSD in an external Inatek case for the past couple of months. It has been working very well. I went to an SSD for potential speed and reliability. The speed is good, reliability will take time to determine. This morning, I re-organized my work desk. In the process, I...

Re: Edson Programmable robot

Python2 is deprecated but still usable. It is included in the python distribution that is standard on the Raspberry Pi. Once you get your bot working with Python2, it would be a good exercise to convert the program to Python3.

Re: external power supply samsung power bank

Very good. I will order a couple of the official power supplies. I guess I was mistaken about the Anker.

Besides, it will support the Foundation which is a very good thing.

Thank you so much,

Bottom line: What is a recommended USB C power supply that will support the RPi 4 with an external USB adapted external SSD? I have an Anker USB C power supply that is rated at 5 volts 3 amps. I still get low voltage warnings from time to time. I have quality cables that are pretty short. Thank you,...

Re: Arm 32 bit Assemply in Raspi OS 64?

I was afraid of that.

I am experimenting with AAarch32 and AAarch64.

The easiest thing to do is swap out SD cards or have two different RPi s to boot.

Thank you.

Re: Increase Number of Lines in Shell Terminal?

No joy, yet.

stty still reporting and displaying only 24 rows (lines) regardless of the putty setting.

I tried all of the above avenues to address this issue.

I am using the Adafruit USB-to-Serial (3.3v TTL) adapter. It is supposed to be good.

Thank you for the assistance.

Increase Number of Lines in Shell Terminal?

I am using Win 10 PuTTY to open a shell terminal in my RPi 4 on a USB Port through the GPIO. RasPi OS seems to be limiting the number of rows in the terminal to 24.

Re: STICKY: Raspberry Pi OS (64 bit) beta test version feedback

I have my headless RPi 4 running via USB Boot, now. I used the tutorial available at Tom's Hardware. It was easy to setup with a Kingston 120 gb SSD in an Inatek enclosure. It is running straight from the USB port with no other external power without problem.

Well worth the effort.

Re: Baremetal resources for the Raspberry pi 4B?

I had to downsize my desk for a time. I am now logging into my RPi from my Win10 computer using Putty via a USB connection through the GPIO. I usually use the command line anyway so it is working out well. The RPi 4 with Raspi OS 64 is very fast when compiling.

Thank you for the tips.

Re: python - versions and what is what

IMHO, anyone learning coding today should default to Python3.

Python3 should be the default install on Raspi OS.

Re: STICKY: Raspberry Pi OS (64 bit) beta test version feedback

The multi keystroke problem is definitely due to Raspi OS 64. It is only with the GUI desktop, not the command line terminal.

Standard Raspi OS does not have the problem. In addition, 64 bit Ubuntu Mate does not have the problem.

Thank you,

As performance density increases in an electronic device, cooling becomes an issue. The RPi 4 have reached that level. As with all of my Pis, my 4B - 4 Gb is in a PiBow case. It is ...
