Never got familiar with Dali’s art though he has created some beautiful artworks! Quite interesting: http://www.openculture.com/2019/01/artificial-intelligence-brings-salvador-dali-back-to-life-greetings-i-am-back.html

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. 
It is named after its architect, Friedensreich Hundertwasser. Very famous for his paintings and buildings. More about his life and work here: https://en.wikipedia.org/wiki/Friedensreich_Hundertwasser

Cave paintings are some of the earliest evidence we have that people were capable of abstract thinking. Also we get a glimpse of what they considered important in there surroundings.

Spring has finally arrived. 
Looks like a ladder if you only see the shadow! Now your car needs new suspension springs? 
Spring = spring, I got the joke first afterwards. May I ask which link?

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.

did a simple job for a friend. he has some extra 50’s Jensen speakers and wanted to use them with this GT40 amp.
he told me GT40 has mono and stereo output mode. so, we decided to leave one of the 6.5″ speakers as it was. then put a long thread 1/4 jack on the other output.
the only place I found for the internal/external switch was the inside of the bass reflex vent on the back. the back panel itself is too thick to attach the switch.

purchased Adzam branded Heerlen 12ax7 and Brussels 6v6gt from from this ebay seller. they were NOS and the pricing was very good indeed.

I dropped by a friend’s place to pick up my big red bum fuzz and hang around. then I dug this EH germanium OD out of a big plastic box.
I’m not sure what this NTK275 exactly is. but the same one shows up on ebay. and I guess it came from 60’s or 70’s
It’s the pile I dug out my bum fuzz and this germanium OD. I know few more guys with the same symptom. falling in love with fuzz pedals. don’t worry. some of them have wives or girlfriends. not all of them of course.

this wide panel tweed deluxe 5d3 came to me with weber 12a125a speaker a few months ago. it was a very good combo and the price was fair with the new skin. but, I couldn’t stand the blue color of 12a125a. everything else was good to me and my friends.
I’ve tried a like new ’51 p12r without bell, re-coned ’53 p12r came out ’54 5C3, black ’61 p12n, and this ’51 p12q.
p12q is known as one of the original speakers for fender tweed deluxe. but didn’t have a chance to play with p12q before.
p12q breaks up early like p12r. it was my first question while I was searching this speaker. and the question has solved.
I was obsessed with vintage jensen speakers a while ago. especially with p12n. but it didn’t work well with 5d3 because of the breakup point. or the family and the neighbors.
then p12q came into my mind. the sound was great like p12n even at the lower volume. and breaks up early enough like p12r in my imaginary world before I actually got this speaker. and it came true. I love this setup and won’t change the speaker again.

all the black plastic parts have changed with vintage correct white ones. this Joe Bonamassa burst #70 has beautiful top and dark back with ’59 profile neck and Burstbucker #2 and #3. the orignal 50’s burst Les Paul guitars mostly had 7.5k to 8.4k pickups and many of them had hotter ones on the neck position.
Gibon’s burstbucker was made after the original PAF pickups which had unbalanced bobbins. I’d put #3 on the neck and #2 on the bridge. personally the best PAF replica was Timbucker from Tim white I got at 2003 with my Brazilian freboard 59 historic. and, at the time a few friends on Lespaulforum.com tried Seymour Duncan Custmop Shop PAF replicas and it was a great pleasure to listen them.
The same Duncan Custom shop PAF pickups are coming for this Les paul. and I believe he’d love them over burstbucker pickups
more vintage correct parts like truss rod cover and square jack plate are coming as well.

found this nicely built 5F1 with 10″ WGS speaker in Mergili cabinet on Ebay while I was in search of the parts for my first 5F1 build. grabbed it off for very good price and I’m changing the components and wires one by one like the filter caps, bypass caps, speaker wires along with the plug.
I think the speaker wires and Amperex 12ax7 changed way more than the capacitors. I’m waiting for yellow and red Jupiter 0.022 caps as well. an A/B comparison video on youtube was very interesting. and red one looks very close to the original Astron firecracker.
there are few tweed amp inspired cabinets around. and it’s the first cab I like except for the original ones. this cabinet sings with WGS ceramic speaker. I’ve been biased toward vintage Jensen alnico speakers so far. and this speaker changed it a bit
the orange filter caps are Roederstein 33uf 450v which replaced the stock caps from the kit. I didn’t know the limit of 5y3 and was brave enough to put two of them on it. then realized the rectifier was too hot and went to 33+10+10.
the first 33uf right next to the rectifier seems fine so far. I’ve tried on the original 5D3 and 5F1 without an issue before. this very capacitor is one of the caps I trust most
this 5F1 is dead quiet and the filament wiring is a bit different to the original champ. I’m trying to figuring out it. nothing is easy with the electric stuff even 5F1 is this simple.
I’ve got some NOS Sprague black beauty caps 15 years ago and tried it on this amp. I expected something vintage with them. but I’ve learned they are not useful as the coupling caps. they were good as the guitar tone caps. but they dramatically reduced the output volume regardless of the values. realized why my 18watt replica’s output volume was that low 15 years ago today. I’m still wondering why anyway.
[update] the sprague caps I put on this amp had twice high capacitance than the marking. I couldn’t find any 0.02 and tried 0.03 but they actually were over 0.05. higher capacitance changes the frequency and reduces the output volume as I learned from them. and NOS caps need time to break in. they sound getting louder for the last few days
