Re: Temperature and Humidity Control for Germination of Pepper Seeds

Thank you @OmnIoT.

Can your solution reside concurrently with the previous solution (NodeRed from @PhatFil) or needs its own RPI?

Re: Temperature and Humidity Control for Germination of Pepper Seeds

Thank you @PhatFil , very thorough instructions. I had some issues with Node-Red. It seems to be working now. Will advise once I have this working.

Thank you, and tell me a bit more. In fact, I do have two of the Flora sensors. They're BT of course. My 'restriction' about no additional hardware should be re-worded ... I tried lately to get few things from Amazon and their delivery schedule says 2-3 weeks. If the needed hardware is available els...

Temperature and Humidity Control for Germination of Pepper Seeds

It's Spring time here in NA, and many like me get into gardening. Of course, one can buy small plants from the local nursery and tend to them, but where's the fun in that? Most seeds are fairly easy to get started (tomatoes, cucumbers, melons, etc) but when it comes to peppers, it's always a challen...

I'm contemplating building a Light Spectrometer, possibly based on the AS7265x (still searching for viable/candidate options). What I'd like to do is the following: 1. Measure Spectra of various lights (either home or for growing plants indoor) - More for fun/curiosity than anything else 2. Potentia...

Re: RPI4 as FTA Receiver ... ?

You're absolutely correct. I agree the RPI does not have the proper wiring/components, but there must be add-ons to accomplish what I'm after.

If anything at all, there 'could' be a way to make an FTA receiver 'slave' to the PI, and have the PI do all the 'smarts'.

So, any other ideas/options ?

I read on a separate forum that earlier versions of the RPI4 had a serious issue with USB-C power and that such issue was fixed with a new board in late 2019. Got few questions: 1. How do I know whether any of my 4 RPI4’s have the old or new PCB ? 2. Per the other forum, the fix was rolled out ‘quie...

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

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.

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.

Thanks.

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'

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 ...
