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.

on March 22, 2019

I remember the word “wasser” means water. and haus sounds like house. what’s the meaning of Hundertwasserhaus?

on March 22, 2019

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

🇬🇧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.

  • en Yokomo Hotdog4 build from YR4 kit

  • I started this build on my personal blogspot blog. then I moved whole the articles on slowbean. I might want to arrange them into one single thread later.

    it’s my yokomo Hotdog4 built from YR4 kit with some Works bits, along with Yokomo Esprit stock motor. I’m working on the new shock towers. 

     

    MX4 rear CVD bones fits perfect for ’91 through ’93 Works. Hotdog4 has the same arms. and you guys can see the result. the length is same with post ’94 yz10 rear cvd bones.

  • en Blackface Champ AA764 pics

  • BF champ AA764

    the voicing of stock 8″ speaker is quite different to 50’s Oxford 8EV. I guess this stock speaker came from Oxford as well but I could be wrong.

    I replaced the stock 25uf 25v power tube cathode bypass cap to 47uf.

     

    it came with stock Amperex buggle boy which is still alive and kicking and GE 6v6gt. only the rectifier tube has replaced at some point.

     

    stock speaker is on the right side.

  • en Fender – Jensen speaker phase were reversed in 50’s tweed amps

  • I just tried 9V battery trick for 50’s Fender Champ 5F1 and Deluxe 5D3. and the speaker wiring turned out being reversed. both of them still have the factory wiring.

    And, both of them move backward (to the magnets) when they wired 9V + to the white wire, and – pole to the black wire.

    They mostly say there is no absolute speaker phase unless they are in the same cabinet. at the same time, many people say the speaker cones move forward when they hooked up in the right direction with 9V battery.

    Fortunately, 9V battery didn’t kill my 8″ Champ speaker, nor 12″ Deluxe speaker. but I’ve read some cases this trick killed their speakers.

    I’m not sure with 50’s and 60’s Jensen speaker’s correct phase. but, I started to believe Fender hooked them up this way. I’ve seen only 2 cases. and will update if I come across any Jensen speaker with different phase.

  • en Static electricity could charge our electronics.

  • 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.


    (Image credit: Schlueter/Getty)

    “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.

  • en Belden E3462-C cord makes my tweed amps dead quiet

  • needed a longer AC cord for my 5D3 and tried E3462-C cord. this cord noticeably reduces noise even while it has more amps and computers share the same AC and audio source.

    then I replaced all the AC cord with this for my tweed amps. the most dramatic change comes to ’59 5F1 which was quiet alone but it cannot be hooked up with AB box. even 60hz hum was loud when it shared the same AC power source without AB box. ground lift didn’t work either. it just shifted the noise frequency

    this seller has the cable. but, only one of three was correct. two of them were E3462 without C. they are metal shielded and the noise was louder than 2 prong cord.

    https://www.ebay.com/itm/Black-CPU-Power-Cord-Cable-SVT-E-3462-C-LL-30830/253801406241

     

    found another seller had the correct cable. and finally all of my tweed amps are dead quiet at any circumstance with E3462-C. even there is no difference between the original and modern 5F1 with or without the center tab.

     

    and this typical ac cord wasn’t that bad for 5D3 but there is a huge difference with 5F1. E3462-C is still way better for 5D3 as well.

  • en Sola Sound Bum fuzz with NPN OC139 Germanium transistors works great

  • 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

    https://www.ebay.co.uk/str/J-H-Components-Limited/Transistors-Vintage-Germanium/_i.html?_storecat=14509182015

    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

     

    Came across this big red bum fuzz here on reverb.com https://reverb.com/item/17423735-sola-sound-cheap-ass-bum-fuzz-jumbo-tone-bender-direct-from-sola-sound-london Sola Sound / Macaris sells a few different versions with different components along with the pricing. this one is a literally cheap, actually the cheapest version of them. they had/have more coming as well. http://www.macaris.co.uk/colorsound They have 3 different versions by the price. £399.00, …

  • en Tamiya Tamtech Buggy Champ

  • I’m running this small version of Buggy Champ – Rough Rider for years. yes, it’s small and cannot run on the bumpy tracks.

    and I watched it’s not bad on the the rally circuit where I’m running my old RC10 and 834B runners.

     
     
    I started from finding a better motor for this 1/16 Buggy Champ. sport-tuned motor from tamiya was the most easy to find. but it turned out not much better than the stock motor.
     
    they released a better sport-tuned SPT recently. and, I was told it was good. I’m thinking getting one at some point. 
     
     

    this tamtech champ came with the plastic spring dampers. buggy champ runs like tamiya grasshopper with the stock shocks. actually it runs better than grasshopper.

    google found me Losi Mini-T shocks weeks or months ago. an I’m running with the shocks. losi shocks turned this tiny champ into a racer.

     
    Losi shocks are slightly shorter than stock ones. and this length is better on the tracks and my living room.
     
    Losi front shocks have almost twice bigger stroke with a dead center. and, this simple trick with shrink tube is working great. 
     
     
    then I came back to the motor.
    a friened who is an expert on the small motors told me to find “Speed 300 6V” motor from Graupner or GWS. 
     
    Speed 300 on ebay.de
     
    ElectricFly  T-370
     
    but the shipping charge for one single motor was overkill. I found this for less than $10 include the postage from somewhere.
     
     
    this E-sky 370 motor is cheap and can be found everywhere. it has this 1/10 style endbell as you can see. the size is identical to the stock 370 motor.
     
     
    the torque and speed are great for the scale. and it turned out this motor needs too much juice for the size. I might need more or better batteries.
     
    I ran with this setup for a while, then I went to Tamtech SPT motor and new shell. SPT is much better than older sport tuned motor in every way. I have brushless in my mind too. but the price is an issue for me.
