My late wife took her own life to stop Chronic Pain.
See our documentary Pain Warriors about that whole saga.
It can be watched for free on Amazon Prime and TubiTV and a few other places.
I receive no renumeration of any kind from the documentary.
Pain Warriors is five stories, four with people with Chronic Pain and one of a doctor punished for helping people with Chronic Pain. Two of the people took their own lives to stop the pain, one being my wife Karen.
Consider that, to my knowledge, we still have no simple objective test that will tell me that you are hungry. Hunger is a mild form of pain.
We have a long way to go before we have objective measures of Chronic Pain.
We must put more effort in finding solutions for Chronic Pain.
For Karen she was told "The pain has become fixed in your perception". That was the best the Medical Establishment had to offer her early on.
Note that the original data sheets said that these could be wave soldered. ABSOLETLY NOT. Even hand soldering they must be treated with respect, a lot of respect.
One of the major problems with these is there a minimal voltage that they must not go below. Their life gets shortened. I've never seen data on how much.
To my knowledge Li-Ion Capacitors were first introduced to the market by Taiyo-Yuden in 2010. They are no longer in this market. I wrote a blog about it back then:
Research that was updated in 2013 from the quoted 1995 speculation:
"… Men and women's brains are connected in different ways which may explain why the sexes excel at certain tasks, say researchers. A US team at the University of Pennsylvania scanned the brains of nearly 1,000 men, women, boys and girls and found striking differences.
Male brains appeared to be wired front to back, with few connections bridging the two hemispheres. In females, the pathways criss-crossed between left and right. …"

Have you tried a backwards polarity tantalum capacitor?
I've seen those go off just on their normal voltage when installed backwards. Sometimes immediately and other times with significant delay.
Eye Projectile and Eye Flash protection along with hearing protection are required.
This reminded me of a Blog entry I wrote about in 2013 on "Massive Electro-Pyrotechnic Initiator Chip Resistor (MEPIC)". These are 0805 chip resisters that are by design meant to let out the Magic Smoke that runs all electronic parts.
Sadly I could not get free samples from my Vishay Rep, that I was in good standing with. MEPIC85N8R0KTT come in lots of 10,000 to buy.
Be sure to check out the application note "A Guide to Using EPIC / MEPIC Igniters in Pyrotechnic Applications".
This is what I wrote about the MEPIC parts a long time ago:
"MEPIC resistors, also known as bridge resistors, are resistive elements that convert electrical energy into heat energy in a precise electro-thermal profile for the purpose of initiating a series of pyrotechnic events in a controlled energetic reaction. [They go BOOM on command, which is different than Rapid Spontaneous Self-Disassembly.]
The new Vishay Sfernice resistor is optimized for electronic igniter applications in automotive safety systems for the deployment of airbags and other safety devices; digital blasting in mining applications; and in fireworks applications for better synchronization of fireworks, music, and special effects.
With firing energy down to 1.5 mJ and a typical ohmic range of 2 Ohms (+/- 10 %), the device provides designers with very predictable, reproducible, and reliable behavior.
Offered in the standard 0805 case size for the wraparound and flip chip versions, with other sizes available upon request, the resistor features easy set-up of firing levels, and is compatible with various pyrotechnic compositions.
Offering ESD withstanding to 25 kV without extra protection, the MEPIC resistor's performance meets no fire/all fire conditions and the requirements of USCAR, AKLV16, and major car manufacturer standards.
The device is RoHS-compliant and conforms to Vishay "Green" standards. [Is it not great that Fuzes are 'Green'?]"
I have found this ST Discovery kit extremely useful in figuring out what my USB-C power sources could actually supply.
"The STM32G071B-DISCO Discovery board is a demonstration and development platform for the STMicroelectronics Arm® Cortex®-M0+ core-based STM32G071RB microcontroller and particularly the USB Type-C™ and Power Delivery controllers.

In World-War-One J.H.Rogers invented and patented an antenna that worked well underground or underwater. It was used to communicate with Subs at the time.
According to the late, and somewhat controversial, T.E.Bearden the Rogers system has been rediscovered and then "lost" at least five times since WW1.

While not indented for water use the Sutton & Spaniol et.al.'s "Black Hole" Antenna is always of interest when it comes to VLF/ELF. This work was done for NASA. Dr Sutton described it to me this way:

Hi Bob,
The synchronous detectors were used in temperature monitors and temperature controllers designed to control temperatures on spacecraft at 60 milliKelvin +/- a few ucroKelvin. The preamplifier had to have a gain of 10E5 after which the demodulated signal had to be converted by a 16 bit ADC, with +/- 1LSB allowable error.... so of course, you can see that we were working with extremely small signals buried in the noise, and we had to go all out in an effort to beat down the noise. That's why we had to use a new improved synchronous demodulator. This project was as close to being impossible as you can get! I still have trouble believing that we actually made it work.
The active ("Black Hole") antenna was developed in another project, where we didn't want to transport a two meter long antenna that weighed 200 pounds.....so we miniaturized the hardware while simultaneously expanding the antenna field cross section. We wanted to receive the entire ELF-VLF bands all at once, so we had to have an extremely broadband antenna....like four decades of bandwidth or more. You wouldn't believe the arguments I had with the reviewer at Physics Essays. He just couldn't believe that one could do what we did....and if it was indeed true, then why hadn't someone done it years ago?.., "and what makes you so smart", .so, of course, "this must be nonsense, etc....." Progress in physics is so bloody difficult because most physicists think that everything worthwhile has already been discovered....so they expect nothing new. This is negative feedback which, of course, makes the system stable, I suppose.
The one text book that includes diagrams of the antenna-external field interaction is listed as one of the references in the Physics Essays paper. Sorry, I can't remember the name of the author or the title.
In the fall of 2023 I tried to visit Stonehenge.
We arrived at 15:15 local time.
I was riding in the passenger seat.
There was a male and female police officer standing at the side of the road, beside a "Road Closed" sign blocking the entrance.
The male police officer came to my window and started yelling in my face:
"We are closed!! Come back another day!!!"
I knew it would be pointless to argue with this a-hole and there was no other day in my schedule that we could come back. So we left and never got to see it.
Do these old rocks get tired at three in the afternoon or what?
I'll be sending this Head of Stonehenge an email about the experiance...
I can see both sides of this. I really want different part numbers for the same reason you do.
However we deal with a lot of regulated products and to just open a case at one of the Government Paper-Pusher Regulators will cost us $5,000 to just change the part number. We are a small company and $5k hurts.
I got one of those take down notices because I had their catalog of Space Grade Rad Hard parts on my website. About six directory levels down; did I give TI permission to invade my site?. Any Human would have seen it as promoting their parts, which was not the direct intention. The Bot just said it was a Copyright violation and I had to remove it from my site or they would send lawyers after me. It wasn't worth the time to fight.
I've been screwed by TI many times in one way or other. As have colleagues.
They did a die-change of a MSP430 and it stopped working in their product. No answer was forthcoming from TI.
I had designed in a Silicon Labs Bluetooth module a few years ago. Now that TI has bought SiLabs, I'm designing it out. I simply don't trust TI. They once were a good company. They went downhill fast after they got rid of all of the support people and moved support online via forums.

I remember seeing in a Popular Electronics Magazine, in the late 60s or early 70s, stating "There will never be a Blue LED". Despite looking I've not found that issue again.
In Tom Beardens book "Excalibur Briefing: Explaining Paranormal Phenomena" on page 166 he states:
"...Briefly, two groups of cells were selected from the same cell culture and one sample placed on each side of a window joining two environmentally shielded rooms. The cell cultures were in quartz containers. One cell culture was used as the initiation sample and was subjected to a deadly mechanism - virus, germ, chemical poison, irradiation, ultraviolet rays, etc. The second cell culture was observed, to ascertain any transmitted effects from the culture sample being killed.
When the window was made of ordinary glass, the second sample remained
alive and healthy. When the window was made of quartz, the second
sample sickened and died with the same symptoms as the primary
sample. The experiments were done in darkness, and over 5,000 were
reported by Kaznacheyev and his colleagues. The onset of induced
complementary sickness and death in the second culture followed a
reasonable time - say two to four hours - behind sickness and death in
the primary culture.
The major transmission difference between window glass and quartz is
that quartz transmits both ultraviolet and infrared well, while glass
is relatively opaque to ultraviolet and infrared. Both quartz and
glass transmit visible light. ..."
