Beim Handykauf war mir die Qualität der Kamera egal, da ich ja sowieso immer eine (halb-)richtige™ Kamera mit mir führe. Bis man letztere dann halt irgenwie zuhause vergisst und mit schlechten Pixeln hinter seinem Funkturm sitzt.

…What's the frequency, Kenneth?…

Die meisten Nutzer von solchen Funksystemen für Headsets wissen nicht, wie man die Frequenzen einstellt. Auch gegen die Feedback-Anfälligkeit der Mics mit Kugel-Charakteristik haben sie keine Waffen (oder wissen nicht, wie man sie bedient). Naja. Das sind so die kleinen Dinge, die mir den Job sicherer machen.

Noch. In Zukunft macht das KI.

For a long time, I used three access points at home. A few months ago, I decided to downsize and see if, with technological advances, I could reduce the number of APs. Obviously, the more remote areas would be penalized, but at the moment I don't need a lot of bandwidth, just stability. So I kept only the Omada 670 - hung from the ceiling, roughly in the center of the house. The coverage was fairly complete, except for a few unimportant corners. It was ok-ish.

I had the opportunity to get a Ruckus R550 at an interesting price (for a Ruckus, of course) and, despite having lower speed performance than the Omada, I wanted to try it. Initially I was disappointed. The coverage was almost the same (but the Ruckus is in a slightly worse position, about a meter from the Omada but resting on a wooden piece of furniture), so I didn't see the advantages. However, I left it running, since I had it. The network remained stable for months.

A few days ago I needed the poe injector I use for the Ruckus (while the Omada is powered by its own power supply) so I reconnected the Omada and turned off the Ruckus. Same channels, same configuration.

Suddenly, I realized the difference. Even seeing (almost) the same signal levels from the monitoring apps, the actual performance is very different. Even in a distant room with many walls (of brick and concrete) in between, the 5Ghz signal of the Ruckus remains stable and reliable, while with the Omada it was much less stable. As "bars", almost the same. But with the Omada it is a continuous packet loss and switching to 2.4 GHz. Moreover, the most distant device (a Raspberry PI A+ with FreeBSD) with the Omada loses signal several times a day, with the Ruckus no problem and despite having a minimum bandwidth, it does not lose packets.

Going back to the Omada for a few days showed me that yes, there are differences. Yesterday I reconnected the Ruckus. Gone, again, all the problems. Of course, with the cost of a Ruckus (on offer) I get 3 "superior" Omadas, but the difference is there.

I'm so proud! #Sennheiser never would have allowed a #garage-built #proton-pack to make it in to their behind-the-scenes video! (That's me starting at 2:36)

For contrast, don't miss the Sennheiser #Spectera video.

I'm doing the next generation protonpack #fpga telemetry system as an #opensource #openhardware design.

Team #mastodon will help me out, right?

Lotsa people interested in this 👍

Wireless mice are surprisingly usable today, if you're like me, and had only used the earliest ones for comparison -- terrible battery life, sudden dropouts, latency spikes, all the rest. I'm reminded that's not the case any more when I do tech support for my father, who uses an Apple wireless mouse. All Apple mice are terrible for other reasons, but the wireless part of it basically Just Works.

I had to switch from a #mouse to a #trackball many years ago, and what drives me nuts is that it's difficult to find a mainstream trackball that isn't #wireless. A mouse you have to move around, you can at least make an argument that being wireless has advantages - but for a trackball, that's just not the case.

You know this, but if you really haven't used that mouse at all before, the scroll wheel will likely quieten down soon enough. Doesn't take much to wear the sharp edges off the clickwheel mechanism. You can also get replacement mechanisms, cheap, if you care to fix one where the mouse wheel is the only problem.
