@design_RG Sounds pretty constructive, I approve :)

I've been spending it brushing up on some relativity and going all the way back to maxwells equations just to reenforce it as it has been a while.

Also I think im going to finish working on my ROES project now that I'm back in my philly home with my lab.

@freemo It's been fun, I hadn't worked on them for a few years, jut didn't feel like it.

Many small repairs, parts moving around, sold some Vintage bikes for reasonable prices to people who will ride and enjoy them more than me, with so many here in the stable. 😄

@design_RG I find that kind of work frustrating personally. I get everything in place and then it makes a noise or doesnt work right, and usually my back and hands are too sore and im just like "fuck it" and pay someone to fix it..

The physical engineering part has always been my weaker aspect, im amazing at theory, but the actual building.. ehhh.. Like in EE, I will design a great circuit but when it comes to building the housing it looks like a 3rd grader did it.

@freemo Ah, I see. 😄

I like the building of things as well, although sometimes they do test your patience. I just finished building a new old bike (a low budget vintage build for someone who saw one of my listings, but didn't move fast enhough to come and snap it before another buyer.)

This bike tested my patience all right, I did tons of work on it, and had many small problems, needed parts or to find some way to make things work with what I had in hand, but managed. Came back from a 10 Km test ride and it was all good, delivery tomorrow possibly. :)

And sold another two vintage bikes earlier today, a young couple came along and loved the bikes, they fit them well, and everyone was so happy. Me too, knowing they are going for a good home. 😃

@design_RG Well all that hard work and patience is also just what makes it rewarding when it all comes together in the end.

@freemo Yes, and I believe is part of our own evolution process. Lessons we learn, a path we are suggested to follow, although we have some freedom to resist or abandon it; then other paths will open.

It always seems to be learning, and sometimes that is about perseverance, humility, stick with it-ness. 😃

@hrisskar You and the rest of the world :)

@Satyr4Nymph Working and needing to go on location still then yea.. but even people working from home have an extra hour or more free time now.

@freemo
That is true. Commuters can have 1-5 more hours per day depending on their situation.

I'm still on location but the fewer cars on the road saves me about 30 minutes 🤷‍♂️

@Satyr4Nymph At leat your getting a little something out of it I guess.

@freemo
🤷‍♂️
It's mostly been a loss so far, but eh historically we are getting off pretty easy

@goddessnatasha Yea, I thought so.

@obi Its better than wasting the time at least!

@freemo No doubt! Perfect time for many to do something constructive, like learn a new language 👌

@aetios sweet deal at least :)

@comphys Nice! It is easier than you may think.
I will need to order some new PCBs soon too.

@freemo It worked out okay. I struggled to keep my RF and power grounds separate, and I learned about stitching capacitors. I made a board with a 16-way splitter and a variable phase shifter on each output. Went 6 layer PWR,GND,Input,Output,GND,PWRGND. The input and output will both resemble microstrips with their adjacent GND planes.

@comphys Just keep in mind PGND and AGND do need to be electrically connected and not fully separated (which can be dangerous). The theory behind separation mostly revolves around where you connect them, in the hope that you keep noise out by giving it a path that doesnt go through the circuit.

There seems to be a lot of common misunderstanding around this.

@freemo thanks, I'll check it out. Ultimately I'm going to put this into a grounded box with sma connectors on the front, so I'm inevitably going to have them connected somewhere.

@comphys yea its usually inevitable anyway. Unless your working really close to the noise floor seperation of grounds tend to be pointless and sometimes even counter productive
