Small-scale BGA soldering

Yes. I proposed Manhattan, Live Bug, Air Wire, 50 Ohm, and don't chop the ground plane. I could never figure out what you were proposing.

I've seen photos of your Spaghetti Ball Air Wire circits. I used to do that long ago but gave up when it got too difficult to modify the circuit or change components. I now favor Manhattan for non-critical components, Live Bug for fast circuits, and 50 Ohm for GHz stuff. Maybe a little Air Wire for one or two critical components.

JL likes surface-mount adapters for SMD stuff, and states

I think that just about covers it.

"Really fast" starts somewhere below 1 ns.

For me, 1GHz goes in 50 Ohm, as well as other signals that need shielding.

I'm aiming for ~10 ps. Connections will be tough, but fortunately there are other pcb materials that are better and cheaper than Rogers. I posted these earlier.

It's been a while since I watched any. (There was some silly stuff.) Are there any good electronics videos? I use to watch some Dave Jones things, but mostly too basic for me. And Mike (someone) taking all sorts of science stuff apart. Fun, but not always educational.

Yeah, Jones got old pretty fast. I've learned a few things from him, mostly about CAD, but the information density is too low and the whiny voice is t oo high. ;)

I like Mike's Electric Stuff--he doesn't just do teardowns. He has a fun se ries on reverse-engineering the iPod Nano display for use in a big installa tion, he's very sound on the stuff he knows about, he has a nice voice, and he sticks to the topic, unlike Jones who is always editorializing.

Paul Carlson is a Canadian ham who does some fun things with old tube gear,

Dashing Firmware Hunchback wants me to do some videos on photodetection, TI As, noise cancellers, and stuff. I might, but it's a big time sink.

Yes he's very good. I find he speaks amazingly quickly and clearly, communicating a lot of information in a short time. Unlike most videos where as you say the information density can be low.

Most videos are just too slow, about 1/20 the bit rate of reading the same stuff.

I made a video for Flir. It was a big deal... producer, video guy with all his gear, lighting, half a day for a few minutes of final product. I did get a free thermal imager, which is OK but not great. It's the benchtop ETS320 which for some odd reason has no focus adjust, which seriously compromises its value.

The worst part of being sick is (usually) the boredom.

Hmm, well I need to make another diode laser video. I'd guess 1/2 a day to script and shoot. And then maybe a few hours editing. (my videos are amateurish, you might want something better.) But in the long run, it's time saved, 'cause I can point people to the video rather than answering questions. I'm assuming your's would be more for advertising?

How too videos are great! There's all sorts of visual stuff that can get confusing with words.

George H.

Yes. I learned how to tape+mud drywall on a Youtube video. Some appliance repairs are great, too.

Those are people doing stuff, not just lecturing.

Amen to that! Doubly so since very few videos benefit from having moving pictures.

The reporter John Simpson (who famously got the Taliban to take him into Afghanistan in a burka) does all his own editing before transmitting the report back to base. His rule of thumb is that 1 minute of reportage takes 1 hour editing etc.

Somehow I don't think that the most 10 minute yootoob videos had a day spent on editing. Most feel like there was ~0 editing.

For your information, I make the world's best ionic silver. I vaguely remember what the flu feels like, but I have not had the flu or a cold for over 2 decades (20 years).

The key is prevention. You cannot start taking silver when you start feeling the symptoms. It's too late by then. You need to take it regularly to kill the virus or bacteria before it has a chance to take hold.

But it is very inexpensive. Once you have bought the silver electrodes, it costs only pennies per day for each dose. The electrodes last for a very long time. All you need is a source of pure distilled water, although this is becoming more difficult to find since most vendors have switched to vacuum distillation. This allows contaminants to flow through the system.

These wreck the elecrolysis process and contaminate your electrodes, which is very difficult to remove. The only solution I have found is to distill your own pure water, and buy new electrodes.

Another issue is how does it work. Most people assume it kills the pathogens directly. This is not true. The silver ions work with the immune system to dramatically improve the performance against viruses and bacteria.

There are no side effects to the silver ions. There is no interaction with any antibiotics or other medicines you may be taking. Unlike antibiotics, there is no indication you have taken a dose. It works naturally in the background, just like your immune system. You don't feel a thing.

It's only after you have been taking it for a while that you suddenly realize you have never been sick since you started. Then it sinks in - it really works.

Another benefit to preventing flu and colds is for people who work with others. You don't catch their infections, and you don't pass any to others.

The only issue is the ionic concentration has to be high enough to be effective. The typical 10 ppm concentration you get from health stores or the numerous self-made generators is not high enough. You need a minimum of about 16 ppm, preferably up to 20 ppm. This is very difficult to do, but I have developed the theory and the means to do it.

what better time to binge on some youtube videos, beats tv anyday

here's a few hours of an interesting repair,

Is the focus really not adjustable, or is it like the E4-E8 series where it is officially not adjustable, but there is a sort-of-gear-shaped recess around the lens that adjusts the focus if you use a tool to rotate it? Someone made a design for a 3d-printable adjustment tool which I use on my hacked E4. The tool is nice as it is plastic so less likely to scratch the lens than needle nose pliers etc. and also it has a hole down the middle so you can see the image during focussing.

Yes. It's very difficult to rotate that focus ring, impossible while it's in use.

I might make some sort of hollow knob and epoxy it around the lens. But we mostly leave it in the box and use our old, wonderful E45.

The .stl file for the focussing tool is in the zip file here:

I got a friend with a good 3d printer to print me a few.

I'd buy one.
