Re: If I buy RASPBERRY PI 4 Model B - Kit 2 GB, is that all I need?

It helps a bit if we are all consistent with the terminology. That said, and Semantics aside, you still have to DECIDE what exactl...

Re: Is a Raspberry Pi ideal for downloading data?

Rather than attaching a hard drive to the PI USB port, you might be better off using a drive with NAS interface ... way faster than the USB 2.0 ports on the RPI 3. You’d have to invest in a wired router/switch and a network (NAS) enabled hard drive. If the backed up data is ‘very important’ (should ...

Re: If I buy RASPBERRY PI 4 Model B - Kit 2 GB, is that all I need?

The one question/decision you need to make is first what exactly are you planning to do. 1. Both Arduino and Raspberry offer you the ability to explore programming and learn few skills However, they are VERY different machines 2. Arduino is a programmable controller 3. PI is a computer If you want t...

Re: No sound through HDMI

One possible reason is that, by default, only ONE of the HDMI connectors supports Sound, not both.

Try moving your cable to the second HDMI connector and that should resolve the issue. If not, then ... difficult to tell.

I struggled with the same issue as well :)

RPI Expansion Boards

I’ve purchased multiple RPIs over the years (20+) along with expansions (Sense Hats and Cameras). Lately however, the RPI Foundation seems to be moving away from PI extensions. We have not seen a new accessory nor an upgrade in a long time. Also, while the latest RPI4 still has the expansion pins/he...

Re: Distances of two different points in x y z coordinates

If you have an iphone, check out the Measure App. It works by using the camera. Essentially, you move/scan the iphone in front of what you want to measure, and based on how the image changes on the screen, the algorithm is capable to 'calculate' some dimensions. Pretty slick, but a lot of image proc...

I tried feeding the HDMI signal to both a Smart TV and a monitor with built-in speakers, and in both cases, no sound. I’m convinced ...

If my memory serves me right, the Pi Zero was introduced about a year ago (give/take few weeks).
