Re: Just received my RPi4b/4GB - no HDMI output!!!

Did you say you just swapped the micro SD card from an RPI 3 ?

That might be precisely problem. I would do a fresh install of the whole OS, and use a different card, just in case you need to recover some settings or other info from the older one.

Re: Kids are getting smarter

Yes, they are! If your teens and their friends are using VPNs, there's not much you can do to see their activity once they're on the VPN. But, here are a few other possibilities for your consideration (beyond that teensy little issue :lol: ) .... HTH Thank you ... seems I have some serious reading ...

Re: Kids are getting smarter

Students used to be quite curious how computer networks were configured. The reaction to such curiosity in the 80s led to the creation of hardened security protocols such as MIT Kerberos--now used for Microsoft's active directory. That takes me back many years ago (30+) ... Back then I was a studen...

Kids are getting smarter

With a couple of teenagers at home and their friends 'visiting' every so often, one has to be 'careful' as to what goes on one's network. There are ways to block certain websites and keywords from the router's settings, but that's good to a point. Then kids learned how to setup VPNs ... My question:...

Re: How to Differentiate RPI4 - 1 vs. 2 vs. 4 GB ?

Here is another point. Luckily, the PI4 boxes are 'tamper-proof' (not tamper-resistant) i.e., you can't just open them and reclose them (as was the case for prior PI generations). A bad scenario but, what if boxes are opened (at a store?), circuits swapped, re-sealed ... and the unsuspecting custome...

Very interesting discussion ... and I found the answer. There are TWO official boxes for the RPI4: Red/White and Black/Gray. Immediately upon opening the boxes, I'm housing the 1GB into the Gray/Black and the 4GB into the White/Red ... Not a solution for everyone, but it'll have to do until we have ...

Thank you all. Like one user answered above, I'm primarily after ways to identifying them from just looking at the (non-connected) hardware. I'll boot them up both and simply attach a small sticker.

Multiple Media Centers - Rather Confusing

First, a bit of history before I ask my questions. I started a long time back (~14 years) with the XBMC (X-Box Media Center). It was one of a few options back then, took some effort, and the result was very rewarding. Fast Forward to today, and we have multiple options (way too many), and it's rathe...

How to Differentiate RPI4 - 1 vs. 2 vs. 4 GB ?

I bought few RPI 4's ... but after opening them (and mixing them) I can't differentiate the 1GB from the 4GB ... any clue?

There are a couple of Youtube movies, but they talk about production date, which to me is not very 'reliable'

I have 3-4 RPI 3's (mix of 3 and 3+) if interested.

Re: Satellite Dish Automation

Not to revive a very old thread, but typically most FTA home systems use a single motor. If we think about it, the geo-synchronous satellites are all located on the same 'circle', which, viewed from any earth location would be an ellipse.

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 ...

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.

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 :)

If you have an iphone, check out the Measure App. It works by using the camera.
