Unfortunately, the vultures have found me -- though not yet dead. To them I'm no more then carrion to feed from -- whose interest is not in me, my interests, or the conversation we might have -- instead their only interest is in how they can prostitute me.

Tops, spinning tops!
What, haven't mentioned them before?
Something else I collect, but not so much recently. Got these two today made by Chase Lindley, one of the premier -- no, perhaps the best top maker -- at least in the world as I know it. The larger one spun for over 20 minutes the 2nd time I gave it a spin -- and I'm not very good at going doing it.
Blerg, I realize I've been in the process of stockpiling hardware, parts, and supplies in anticipation of the impending thaw.
By that I mean the end of this semester when I complete my grad program.
Between a fulltime day job and two online courses at night I have little time for anything but that. Somehow though, I manage to find the time to order and accumulate stuff for the stuff I really want to do.
A Tale of Two Voltage Regulators.
On the left is a LM7805 voltage regulator. All the capacitors and heatsink were needed for filtering, dampening, and cooling to make the #ubitx 5" Nextion display happy. All that heatsink is needed because the LM7805, a linear VR, is pretty inefficient.
The far simpler board on the right uses a module that is a drop-in replacement for the LM7805. It is a switch-mode VR and though rated the same as the LM7805 needs no heatsink.
Please reshare widely and **take action**. This has the potential to endanger the #internet as we know it, making it more and more composed of only large platforms.
I hope this note finds you well.
I write to tell you of an unexpected experience I had while in the midst of creating a post. While hoping to upload a video from my cell phone I was confronted with the distressing message "Invalid file type."
Is #pixelfed limited to still images?
Is there a plan to support video in the future?
Dear kids in Washington State: you can make an appointment with your doctor, or walk into a clinic or ER, and get vaccinated. You don't need permission from your parents. You don't have to wait until you are 18. If the health care provider gets confused, the magic phrase is "Mature Minor Doctrine", and point out that not wanting to catch measles is sign of sufficient maturity.
Please reshare, and copypaste this any place this would be useful.
Top and center in the first pic is a Wavenode WN-2D I just got. It's kind of disappointing the KX3 is says its transmitting 15W and the Wavenode is only reading 11.4.
In any case, I can now go back and and do a proper calibration on that little dummy load power meter.
When I get another moment, that is.
So there is this peer to peer, chat system. It has no tracking or ads, it doesnt require any infrastructure to be 100% effective. You can use it with your computer and type to folks, similar to IRC. You can literally run a BBS over it and many actually do.
Went crazy for awhile last night. Realized I should be able to use the oscilloscope to calibrate the power meter.
But then, every measurement taken differed from the KX3 and the power meter depending on whether or not I was connected to the oscope directly with a cable, with a probe, or if the probe was set to 1x or 10x.
Went back, redid it all, and the measurements made more sense. Now the meter is reasonably calibrated at least up to 15 watts with the KX3, the only reliable hf tcvr I have
It was suggested I post, and pin, a toot with information about what it costs to run this instance.
I like this, I want to be transparent, and I think it's important that the community have trust and confidence in me, and the hosting.
Currently the costs looks like this:
* £112.50 a year for a VPS
* €25.00 a year for the domain name
All media (avatars, etc.) are sotred on the server, we use 20G of 40G so far.

Finally. Got the screws to bolt down the cover and give it a try.
The dummy load. Boom, boom, boom -- 1:1 SWR on any frequency I tried. I guess that shouldn't be a surprise, but sometimes small victories are welcome.
The power meter. It looks to be working too! But look at that discrepancy between the KX3 and the meter? I tried two different cables and get about the same thing. I'll have to wait until I have a chance to take it over to a friend's house and test it against another meter
