One of the most interesting things about DNA is that we have discovered, in humans, the 3% of the code which builds our physical bodies also has encoded within the bodies of all of our ancestors. We can switch on these old systems (in animals of course since this would be highly unethical to do to human beings) and give a chicken teeth or scales. We are not just us. We are all the physical forms in our lineage.
Now, that accounts for 3% of our storage. What of the other 97%? It is memories. Now the skeptic will go “yeah right Mr. Science”. Hear me out here though. Why is it so hard to accept memories encoded into the helix? In fact all “instinct” is encoded memory. What beach to lay your eggs by the light of the full moon if you are a tortoise. Where to migrate if you are a starling or a monarch butterfly. Sharks even have maps of the magnetic markers on the seafloor. None of this is learned. It is there at birth.
There is a very good evolutionary reason for this. Rapid adaptation. We have a repository of past experiences so we do not have to reinvent the wheel every time our environment changes. Human beings have noted this for at least as long as we have records and this has given rise to theories of reincarnation which appeared in nearly every civilization on Earth. Science has resisted this because it sounds too “supernatural” in the same way they resisted the “Big Bang” because it sounded too much like creation. Yet, it is anything but supernatural. It is entirely natural and the only explanation which makes any sense.

while my 5F1 project is not loud enough with Jensen 10J11 speaker, I tried a few different 6v6 tubes for the last few days.
I noticed Ken-Rad 6v6GT/G tubes are louder than the other tubes. and the texture with this tube is acoustic and strong.
I don’t see the difference between RCA, GE, and Sylvania 6v6gt tubes that much. GE Canada 6v6GT is a bit brighter than 50’s stock tweed RCA and 60’s Sylvania but, Ken-Rad 6v6GT/G sounds way different to them

Unhappy with the life of your smartphone battery? Thought so. Help could be on the way from one of the most common, yet poorly understood, forms of power generation: static electricity.

“Nearly everyone has zapped their finger on a doorknob or seen child’s hair stick to a balloon. To incorporate this energy into our electronics, we must better understand the driving forces behind it,” says James Chen, PhD, assistant professor in the Department of Mechanical and Aerospace Engineering in the School of Engineering and Applied Sciences at the University at Buffalo.
Chen is a co-author of a study in the December issue of the Journal of Electrostatics that suggests the cause of this hair-raising phenomenon is tiny structural changes that occur at the surface of materials when they come into contact with each other.
The finding could ultimately help technology companies create more sustainable and longer-lasting power sources for small electronic devices.
Supported by a $400,000 National Science Foundation grant, Chen and Zayd Leseman, PhD, associate professor of mechanical and nuclear engineering at Kansas State University, are conducting research on the triboelectric effect, a phenomenon wherein one material becomes electrically charged after it contacts a different material through friction.
The triboelectric effect has been known since ancient times, but the tools for understanding and applying it have only become available recently due to the advent of nanotechnology.
“The idea our study presents directly answers this ancient mystery, and it has the potential to unify the existing theory. The numerical results are consistent with the published experimental observations,” says Chen.
The research Chen and Leseman conduct is a mix of disciplines, including contact mechanics, solid mechanics, materials science, electrical engineering and manufacturing. With computer models and physical experiments, they are engineering triboelectric nanogenerators (TENGs), which are capable of controlling and harvesting static electricity.
“The friction between your fingers and your smartphone screen. The friction between your wrist and smartwatch. Even the friction between your shoe and the ground. These are great potential sources of energy that we can to tap into,” Chen says. “Ultimately, this research can increase our economic security and help society by reducing our need for conventional sources of power.”
As part of the grant, Chen has worked with UB undergraduate students, as well as high school students at the Health Sciences Charter School in Buffalo, to promote science, technology, engineering and math (STEM) education.

I have emailed to dozens of electric part suppliers and messaged to ebay sellers for
V23084-C2001-A
and I noticed most of them are counterfeit. this seller looked legit with the picture of NOS Siemens relay. but it didn’t go well.
and it’s the the relays I got from this seller
The original Siemens, Tyco, TE connectivity relays have molded bottom with thick and strong lead pins. and, you can buy this counterfeit relay on alibaba.com or aliexpress.com for less $1 each
I’m talking to these two sellers for the original part. and one of them are running this web site
I do trust this guy and made a purchase from his ebay store
https://www.ebay.com/usr/bmwgm5?_trksid=p2057872.m2749.l2754
also this seller has the original relay. but it’s V23084-C2002-A403
the only difference between A303 and A403 is the contact material. and C2002 is sensitive type works with less current as far as I know. I’ll try them both and will update
another seller sent me this picture. and it’s exactly the relay I’m after. you can see the pattern on the bottom but even many of the counterfeit have the patterns as well. but please see the pins carefully all the soldering pins are thick and look strong enough.
I’m ordering a pair from this seller who sent me the picture
https://www.ebay.com/itm/183304411194
it took a couple of months to figure out which is the original and finally found these 2 sellers which I trust on ebay.
I’ll update when they arrive
and please someone advice me if V23084-C2001-A303 can be replaced with
V23084-C2002-A403, or V23084-C2001-A403

didn’t know Jensen had Concert series with ceramic magnets. this PM-1002 sounds more like Jensen 10J11 than WGS Veteran ceramic to me. even I believed it was an alnico speaker when I grabbed this off ebay for $69 plus shipping. then googled what Syntox-6 was after a week playing this in my 5F1 project. a bit disappointed while figuring out what the magnet was. but still happy with this NOS Jensen with the original box. and it is way louder than Jensen 10J11 alnico speaker as I expected.
I’ve tried Mullard and a few different 12ax7 tubes with it. and going to stick with GE black plate 5751 for a while.
