Some monitors lie about their size to Linux. I got a 10" touchscreen that, for some reason, Linux thinks is a 27" monitor and sizes everything accordingly. Unless you have a specific reason to use the

Here's where the MoPi2 hot-swap power supply hat really shines. It takes two 6-30VDC inputs, plus a charge input. Normally, your primary power goes into port 1 and your backup battery goes to port 2.

Pardon my ignorance. You have a local network within your house with just your stuff on it. You have the Macs in your shack and the RPi in the garage. The Macs are on Ethernet and the RPi is wireless.

While you are looking for small TV/Monitors, don't forget to visit your local Goodwill stores. I've bought a bunch of 13-21 inch units for $10-15. I look for the ones that have DC inputs, often 12 or

This project will strictly utilize existing analog FM channels at the site. However, the question is not really the transmission medium, but the nuts and bolts of taking the picture and transmitting i

Here's an interesting project thought. A remote base/repeater site, on a very remote hilltop. No internet or cell service available. I'd like to put a couple cameras up there monitoring a couple diffe

Chris, looks kind of interesting. Unfortunately, your pictures are too small and fuzzy for my tired eyes to see anything useful. Michael WA7SKG Chris Harris wrote on 12/8/21 2:30 AM:

Is anybody experiencing RF problems with the Raspberry Pi 400? I was recently gifted a Pi400 and loaded the HamPi distribution. I don't have RF problems with anything else in the shack, but when I tra

That's my problem. There are tons of complex projects like what you reference. I want something exceedingly simple, but I am not smart enough to write it myself. All I want is a window with either a t

I have a need for a simple remote radio. All I need is two-way audio and PTT. No channel control or anything needed. Ideally, something via a web browser as a few of the users have limited computer sk

Nice monitor, but not touchscreen. However, they do have a touchscreen model at https://www.amazon.com/dp/B082HWF2HW/ref=emc_b_5_t Of course I'd have to come up with some kind of case for the RPi/APRS

That looks pretty much like what I am looking for. I'll see if my son can print one for me. Thanks, Michael David Harris via groups.io wrote on 9/25/21 4:26 PM: .

I guess it was my error in expecting people to understand VESA compliant monitor mounts. It has only been an accepted standard followed by almost all manufacturers of flat panel displays for some 20 y

Not sure of your intent here. The link is simply a picture of a monitor showing dimensions. It has absolutely no bearing or relevance to the issue. Michael WA7SKG Dave R wrote on 9/24/21 5:34 PM:

My current APRS system using a RasberryPi is using a 7 inch monitor in a SmartiPi Touch case on a VESA mount. The 7 inch monitor wasn't doing it for me, so I got a SunFounder 10 inch monitor. It has n

These kinds of comments are totally uncalled for. In my 50 year ham experience, including teaching many license classes, I do not recall ever seeing anything about RS-232 or even serial protocols ment

The first thing that comes to mind is, what are you trying to accomplish? You mention a remote site that is difficult to access. AFAIK, Winlink is mostly a messaging system and is generally used by an

How about something like this? https://www.amazon.com/gp/product/B084G2RH1C/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 Ten ports at 2.4A each. I don't have any RPi 4s, but I power several RPi 3s
