This is a simple DYI project aimed at soldering beginners (like myself :P). For more experienced tinkerers it should seem like really simple and short, but I hope it will help some of you avoid spending money on a new extension cable (and pollute the environment in the process).

So, we have a classic, cheap extension cord with a power indicator in a translucent case. When the extension cable is under tension, the light is lit. Unfortunately, the button was damaged and the light was always on, consuming electrical energy for nothing and generally being useless. I was hoping to remove the light but keep the switch, but that proved impossible.

Below you have the schematic of the circuit of the power strip. As you can see, this is a very simple circuit. The part in red is what I was trying to remove, but unfortunately the switch had to go too, because it was too badly damaged.

The first step is to remove the back panel. It is usually screwed with 6 or 8 screws, depending on the size and the quality (read: price) of the power strip. After removing it, we can see this strip is in pretty bad shape: the metallic strips are al over the place and some of the kid-guarding plastics are broken.


The image above shows how the kid guard works: the red plastic covers the holes. When the plug is inserted, the spring is compressed and the plastic bit gets out of the way. Unfortunately, in cheap power plugs, this doesn’t work as intended. In order to introduce the plugs, you have to use a considerable amount of force, eventually breaking the fragile plastics around there. If you have such problems, you can just remove the red plastic and the springs, leaving the holes uncovered.

Also, before we go on to actually unsoldering anything, I want to show you the light encasing opened. Notice how the translucent switch has melted or was somehow broken, thus rendering it useless. You can also see the 25KΩ resistor linked to the neon light. In other power strips, you could have an LED instead of the neon. This resistor could be reused if you have some other project requiring such a large resitor, but I’m not sure if the light still works.

But let’s get back to the problem at hand. Looking closer at the light, one can see that the connectors are soldered to the light case. In more expensive power strips, the cables could be attached otherwise, making your job easier.

Another important step is to determine which wire is which. In domestic AC power, there are normally 3 wires: live (phase), neutral and ground. If the system is unpolarised, like this so-called „Schuko” (aka CEE 7/4) system, the the live and neutral wire are interchangeable, which means we only have to identify the ground wire. Normally, the wires are color-coded and the ground is yellow-green, but not in this power strip.

In the image below, you can see the green wire is connected to the metal strip from the center of the plug, which means that this is the ground wire. One of the other wires is directly connected to the metal strip, so we only need to unsolder and reconnect the remaining wire.

Here is how the power strips looks after unsoldering all the wires and removing the light case. You can also take a better look at how the wires are connected. One can easily notice that the top black wire is now superfluous, as that particular metal strip is already directly connected to the power cord.

The soldering itself should be fairly quick and does not require special tools or skills.

That’s it, we are ready for a test! The wires are visible through the hole left by the light casing. This is not really nice, so we can just remount the case, which is hold in place by two clips. Of course, the button is now only decorative.

If you look closely, you will notice one of the corners of the button is melted. It wasn’t like this at the beginning, but I accidentally touched it to the soldering iron. You should always be careful when using soldering tools, as they do get very very hot.

Într-o plecare de la sfârșitul lunii trecute, despre care o să scriu mai multe mai târziu, am avut ocazia să constat apariția pe multe din drumurile naționale din Oltenia și Banat a unor indicatoare spre diverse monumente istorice. În principiu, asta este o veste foatre bună. Dar ce faci după ce cotești de pe drumul național (relativ bun) pe un drum comunal plin de gropi sau mai rău, pe o potecă îngustă?

Acum doi ani și ceva, când a apărut prima dată ideea concursului Wiki Loves Monuments România, am plecat într-o plimbare prin Maramureș în căutarea Mocăniței de la Vișeul de Sus și a vestitelor biserici din zonă. Am constatat atunci că dacă monumentele aveau norocul să fie pe drumul principal, dădeai ușor de ele. Dacă nu, îți trebuia musai o hartă sau un ghid.

Indicator de pe DN

Între timp, situația s-a îmbunătățit. Mulțumită proiectelor europene de dezvoltare rurală, multe monumente beneficiază acum de indicatoare, plasate de obicei chiar sub indicatorul spre sat. Pentru unele dintre ele a fost chiar modernizat drumul și eventual au fost refăcute prin aceleași proiecte.

Din păcate, în afară de acel unic indicator, în cele mai multe cazuri nu există nicio altă informație despre sau indicator spre monumentul respectiv.  În cazul monumentelor din sate, singura soluție este să întrebi localnicii pe care din ulițe să o iei. Bineînțeles, ca orășean trebuie să fii foarte atent căci oamenii de la țară au alte referințe în ceea ce privește calitatea drumului și s-ar putea să rămâi suspendat cu mașina pe drumul „bunicel” de acolo.

Pentru orășele, este posibil să mai găsești câte o hartă în fața primăriei sau la gară. Totuși, și aici ai o problemă: să nu care cumva să-ți treacă prin minte a întreba de strada pe care ai aflat de pe net că se află monumentul, căci nimeni nu va ști ce nume poartă fiecare stradă. Este oarecum de înțeles, având în vedere și obiceiul unor primării de a da mai multe nume aceleiași străzi. De exemplu, în Oravița strada principală se numește, pe rând, Andrei Șaguna, Eftimie Murgu, 1 decembrie 1918, precum și „Piața Unirii” și „Piața Ferdinand”, care sunt orice numai piețe nu.

Soluția e să întrebi după numele local al monumentului. Chiar și atunci, s-ar putea ca locuitorii din celălalt capăt al orașului să nu te poată ajuta…

Să zicem că totuși ai răzbit până la monument. Ce ai de făcut acolo, în afară de poze pentru concurs? Dacă nu ești specialist în arhitectură, și majoritatea vizitatorilor nu sunt, nu mare lucru. Cu toată avalanșa de site-uri „specializate” pe monumente apărute recente, puține au informații originale, relevante pentru un număr mare de monumente. De cele mai multe ori trebuie să „sapi” de dinainte în căutarea unor informații.

Această gaură informațională ar trebui, după părerea mea, umplută de cei care întrețin monumentele. Mulți au ca scuză faptul că nu sunt fonduri nici pentru reparațiile de primă necesitate, darmite pentru informații… Și totuși, nici măcar acolo unde au fost bani pentru restaurare, nu s-a investit (aproape) deloc în ceva indicații pentru vizitatori.

Indicatoare

Un exemplu relevant mi se par morile de apă de la Eftimie Murgu. Fiind un monument eminamente tehnic, este oarecum logic ca vizitatorii să aibă mai multă nevoie de îndrumări asupra modului de funcționare decât în cazul unei biserici sau al unei case particulare. O parte din aceste mori au fost refăcute de muzeul „Astra” din Sibiu acum câțiva ani într-un proiect european.

Plăcuță cu numele morii

Au fost instalate câteva plăci în imediata apropiere a monumentelor (fără a acoperi zona dintre DN și sat, bineînțeles) și fiecare moară în parte avea numele ei și numele proiectului. Nimic despre modul de funcționare, amenajările necesare sau istoricul acestor mori. Din fericire, două dintre ele sunt încă funcționale, iar proprietarii lor sunt suficient de amabili încât să-ți explice toate detaliile și legendele locului.

Ce-i drept, dacă ne-am fi făcut temele din timp, am fi aflat poate că în școala generală din sat există un mic muzeu cu o moară desfăcută. Din ce-am văzut însă în pozele găsite pe net, și aici trebuie să te bazezi pe bunăvoința ghidului…

În aceste condiții, tot ce vă rămâne de făcut ca turiști „vânători” de monumente este să citiți cât mai multe despre monumentele din zona unde urmează să mergeți (puteți începe cu o hartă a monumentelor din țară [se încarcă greu] și cu Wikipedia) și eventual să vă înarmați cu un telefon mobil și acces la net.  Pentru cei cu smartphone-uri Android sau iPhone vă recomand aplicația „Monumente România” realizată de Asociația Prietenilor Muzeului Național de Istorie a României, care îmbină în mod fericit harta și un modul de realitate alternativă cu paginile de informații ale site-ului lor, paginile de pe Wikipedia și câteva mii de imagini.

Voi ce alte resurse folosiți pentru a profita cât mai mult de vizitele unor monumente istorice?

The road

Map

Many of the Romanians that go to Austria for ski or other forms of tourism choos to go by car. From Budapest to Vienna you only make about 3h on the highway, and from Bucharest to Budapest a maximum of 12 hours. It takes roughly the same ammount of time by bus.

You can also choose the train. The journey takes 20h and you have 3 trains every day: one direct trains and two trains via Budapest.

We chose the third way, the plane. Austrian has 5 daily flights and Tarom 1 or 2. That means you will find decent prices even with a few days before the flight. The flight time is 1h45 – less than the ground checks (as you know, airlines recommend arriving at the airport 2h before the flight).

Even if the trip is a little long by car or train, the diversity is a good thing, earning the route a good score.

[rating:4.5/5]

Accommodation

Vienna has a huge diversity of hotels and even more flats you can rent. In past visits here I chose low-cost hotels near the railway station, but this time, we rented an apartment from govienna.net, one of the two from Quellenstrasse.

The apartment has scores pretty much OK on the Internet, but for us it was a disappointment. The building was in the Turkish neighborhood, but there were no issues except on the New Year’s Eve, when people were still throwing firecrackers at 3 or 4 A.M. when we returned from the city.

The exterior of the building looked decent, but the stairs were in really bad shape and the apartment had a weird smell. There was enough furniture for 4 people, but there were some weird stuff, like the window above the entrance door or the toilet which was separate from the bathroom.

What to see

St. Stephan’s Cathedral

Stephansdom is The Cathedral in Vienna. There are other churched in town, but this is by far the most interesting and probably the biggest.

The entrance is free and so is photography (but without flash). The interior seemd a little darker than other cathedrals from Europe, probably due to the fact that we went in winter. Still, this was helping to underline the beauty of the stained-glass windows.

Some details from the interior:

After finishing with the interior of the cathedral, we decided to pay up 4€ to clinb the south tower. Although the panorama is interesting, the horses from the place look much more interesting 🙂

Talking about the panorama, let’s look to the Prater…

…and then to the bells of the cathedral (can anyone translate the inscription?).

After descending from the tower, we stick around the cathedral waiting for noon. Why? We wanted to see the Anker clock.

The Anker clock

It was built between 1911-1917 and it is both a figurine clock, but also a bridge between the two parts of the Anker building. The 12 figurines move at 1/hour, except at noon, when they all go through the window in 10-15 minutes.

We then went on for a stroll downtown, admiring the different monuments of the city.

For lunch, we couldn’t miss the famous Wienerschnitzel:

Haus des Meeres Vivarium

Although recently returned from the Asia trip , where we saw a lot of zoos of all kinds, we thought it couldn’t hurt to compare them with the European zoos.

We weren’t going to visit the actual Vienna zoo untill the last day of our trip. Until then, we went for an evening visit to the Hous of the seas, a huge aquarium spreading on 7 floors.

As a matter of fact, they were not only hosting marine animals, but also species one would see in the desert or the jungle. Unfortunately the name of most of the species have slipped my mind.

They had all kind of turtles, from the small ones like the one below to the huge, 100-kilos and 100-years-living ones.

The primates had their own artificial jungle spreading on 3 floors on one side of the building. Impressive!

Big turles…

The view from the roof.

The Opera

The Imperial Opera is another one of the buildings that every touristic guide recommends. The size is not really impressive, but the architectural details make up for that.

Interior

The really interesting part is the visit inside. The guided visits start around noon every dai, take about an hour and cost 6.5€ for the adults. The guide is avalable in multiple language, including, of course, English.

We started with the main hall. Note the 3 rows of loges. The first thing that attracted our attention was the scene: fortunately there were no rehearsals (hard on the 31st of December), so we would have full access to the backstage.

Detail of the concert hall.

My mom used to tell me that the really cool part of a theater is the stage, but I didn’t believe her. I changed my mind when I arrived on the Vienna Opera stage.

Imagine 5 floors of scaffolding, pulleys and ropes, all with a precise role in the movement of the stage elements. It was like being in a huge building site, the only thing missing being the workers on scaffolding whistling at the ladies below. 🙂

The rest of the buildng was not bad either, with ceilings comparable with the most beutiful palaces. Perhaps because the opera was one of the favorite pastimes of nobles from past centuries?

The technical museum

As beautiful as old buildings may be, I still prefer technical stuff (professional bias, probably). I was very happy that the group I was with agreed to visit the Technical Museum. Ironically, it was also hosted in a huge Hapsburg palace, but with an entrance made of steel and glass.

Right after the entrance there was an area dedicated to interactive experiments meant to explain some simple physical fenomena. Unfortunately I was too busy playing so I took no pictures, but I should mention that this section had the same size as the whole Bucharest technical Museum.

We then went to the railway section. Unlike other technical museums I’ve seen, in Vienna the locomotives were not just shown, but they were cut open and illuminated in order to illustrate the various components.

The image below shows that Romania is much better off than 100 years ago: at the time we barely had a few steam locomotives, while Austria already had electric locomotives in service.

One of the „hands-on” exhibits: a miniature solar park fueled by a lamp illustrated the energy you could produce.

Followed the factory and industrial products’ section.

These bulbs are light-years away from LEDs 😀

The last floor hosted the plane and car exhibition. Unfortunately, due to the lack of time, we went really fast through that floor.

We still saw some Steyrs…

…a Mercedes racecar (I think it was produces also by Steyr-Daimler)…

… and a beetle (I don’t remember the producer, but it seems another Steyr)

Below we have a Gräf și a few angines, all manufactured in Austria.

Prater

I don’t think the Praterul needs an introduction. In case you haven’t heard of it, you can start exploring from the Wikipedia article.

The City Hall

For the New Year’s Eve we went to the park in front of the city hall. I’m sorry I haven’t had the chance to visit the interior, but if you’re interested, you can find information about guided tours on the website.

Happy new year!

Schonbrunn

The last day was dedicated to Schonbrunn, including the park and zoo. Although the winter views are much less impressive than the palace in a sunny day, I still liked it better than Versailles, which apparently (I’m not 100% convinced) is the original inspiration for this palace.

Unfortunately, photos were forbidden in the palace, so I only have a few outside shots.

The picture below is in fact from the Zoo, but the building was in the same style as all the other buildings from the gardens.

The Vienna Zoo

The Vienna Zoo is the oldest zoo in the world that is still functional (established in 1752). It hosts over 4600 animals from 480 species, including pandas and other endangered species.

In the late 80s it almost went bankrupt, but it was „privatized” (actually, a company owned by the city was created to administer the zoo) and with a smart private manager, it was saved. Sounds a lot like what is happening to some Romanian companies, expect for the „saved” part…

It was the first time we saw a Koala, even if we had hunted it throughout Asia.

Apparently not all marine animals were at Haus des Meeres.

The elephants were a little thin, but not as sad as the one from Bucharest (when it was still alive).

[rating:4.5/5]

Food

You can try pork chops with beer, some ribs or even Chinese food. In this trip we trusted the recommendations found on the Interned ad we did not regret it – even if some restaurants are true food factoreis, with clients coming and going like on the assembly line, they don’t give up quality and keep the prices decent.

Alternatives

Any City Break in Europe will be exiting if you’re going there for the first time – just find a cheap plane ticket and go for it. Closer to Bucharest you have Budapest or Bratislava. If taking a plane, go for Prague, Warsaw or even Lyon and London.
