Due to the heavy bombing in World War II, #Magdeburg has less to offer in terms of cultural attractions than other cities of the same size. But of course there are still enough things to look at and the Hundertwasserhaus is without question one of real gems. Shortly thereafter follows the Magdeburg Cathedral, also a special landmark of the city.

🇬🇧Bagan (Burma) is an archaeological site perhaps less known than the Angkor complex in Cambodia, but it is very similar to it, and historically and archaeologically more interesting. Bagan Archaeological Zone is the formal name used to designate the historical region of the ancient Kingdom of Bagan. It is thought that probably more than 13,000 temples, pagodas and other religious structures were built here. It is a unique heritage built between the 11th and 12th centuries in this area. Together with Angkor and Borobudur it is among the most significant archaeological sites in Southeast Asia and the world.🏛🗿 • 🇮🇹Bagan (Birmania) è un sito archeologico forse meno noto del complesso di Angkor in Cambogia, ma è molto simile ad esso, e storicamente ed archeologicamente più interessante.

Si pensa che probabilmente qui siano stati costruiti più di 13.000 tra templi, pagode e altre strutture religiose. Si tratta di un patrimonio unico edificato tra l'XI e il XII secolo in quest'area.

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 keep checking out the the leather handles since I had some trouble with fender reissue.
the humped handle in the picture came from this company, Industrial Amps it looks very close to the original ones on fender tweed amps. but, the original seemed to have 3 layers.
[udpate] it was 30 something dollars when I found it. and it’s now almost $50.
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.

I just tried this from a hunch while I barely understand electric circuits.
Bum fuzz was made after B&M fuzz. it came from Tonebender Jumbo, and Jumbo came from Big muff. and they are not far from Tonebender MK3. it means this pedal would work with Germanium transistors.
Sola Sound make 3 different versions of Bum Fuzz units with BC184, BC549C, and ZTX109. BC184 and ZTX109 versions look same to each other except ZTX109 version comes with better and older electric components. BC549C comes with cheap ass version. and, it has 3 of different resistors and 2 of electrolytic capacitors at least. I replaced them with 33k, 100, and 100k resistors an 2 of 0.1uf fixed caps.
OC139, OC140, OC141 are NPN germanium transistors for computers (yes, the computer) from late 60’s. They are period correct for late 60’s and early 70’s fuzz I guess. and, have the similar Hfe range as well. most of them I found on ebay.co.uk had 100 to 200 Hfe range. some are less than 100, and some of them are over 200.
It’s the shop I found ZTX109 and OC139 transistors
And, this pedal sounds great with OC139. I don’t see any reason to try a different setup anymore. this modified Germanium Bum fuzz unit has overdrive to medium or leather high gain fuzz range now. somewhat sounds like MK2 and feels like MK3.
It was like this a couple of months ago
purchased Adzam branded Heerlen 12ax7 and Brussels 6v6gt from from this ebay seller. they were NOS and the pricing was very good indeed.
he sent me this tube puller. this silicon tool designed to grab the preamp tubes and the the tubes like EL84. you still need to hold the tube using this puller. and it feels easy may protect the letters on the tube
