Philips „Sonate“ Philetta Euro280

Philips Philetta Euro 280 „Sonate“

In the years 1968 to 1970, the radio receiver was built with the inscription „Philetta Euro 280“ by Philips. It is a small multi-band receiver with transistor equipment. The type designation 12RB280 / 30 with the inscription „Sonata“ seems to be another version of this model. In any case, I have dug up the version „Sonata“ – once again from the depths of the Kellergefilde – and after superficial cleaning connected to the mains. Immediately after switching on, the scale illumination lights up and a loud 50 Hz hum can be heard from the loudspeaker. Increasing the volume level adds some noise. So switched to the FM band and searched for a station – and lo and behold, it works. Only the buzzing disturbs. Otherwise, the device works without any major problems. To find the cause of the humming, you begin with the troubleshooting as usual in the power supply.

The rear panel is quickly removed and the power supply unit, consisting of a, mounted on a support plate transformer including rectifier and filter capacitors removed. Now, without using the oscilloscope and the multimeter, you can immediately see where the ravages of time have left their mark. The two electrolytic capacitors do not look quite healthy anymore.

A quick measurement of the voltages brings certainty. The DC voltages have a decent ripple, which causes the „hum“. So the function of the electrolytic capacitors to smooth the DC voltage is no longer, or poorly, given. A measurement of the capacities confirmed that. So I renewed the capacitors.

Power supply with renewed capacitors

Immediately after switching on, even before I had the probe at the measuring points, a noise was heard without „humming“. The oscilloscope image now showed a clean DC voltage – almost no ripple. The receiver worked again very clean, without disturbing background noise. That was apparently the only mistake.

Technical information:

The main principle of the receiver is a superhet (according to the superposition principle) with an IF of 460/10700 kHz. The waveband of the receiver:

frequency scale
  • long wave
  • medium wave 1 (520-1400kHz)
  • medium wave 2 (1400-1600kHz)
  • shortwave
  • UKW

The output stage has a power of 3W, which is converted into sound energy in a dynamic loudspeaker with permanent magnetic excitation. The case is made of plastic and has the dimensions 43×17.5×10.5cm with a weight of 2.4kg. The receiver is supplied with 220V / 50Hz mains voltage.

Technology toys from the past – made of plastic

This article has nothing to do with electronics. In my retro-madness I was once again rummaging in the cellar of the parents‘ house and discovered there behind dusty jars of musty-smelling cardboard boxes with unknown content. So what was left to me to uncover and view the contents of these cardboard boxes? And what came out here were other boxes of the well-known toy manufacturer „LEGO“. Some very dusty original boxes of Lego-Technik models and old washing powder boxes, which were filled with many, many colorful Lego bricks and other stuff and unfortunately also garbage. Actually, I thought to myself, these many plastic parts I can throw in the trash, because that will not play my son safe. Everything smells like cellar and is dirty and the work, everything to clean and sort will certainly no longer hurt anyone. But on the other hand is the really old toy from the 70s and 80s – so over forty years old. And that is exactly mine again. 🙂 Things from my childhood and memories of it.

So packed everything and transported home. And then, in painstaking work, sorted everything once into colors and freed it from rubbish and lego-foreign parts. And now the real work began. The goal should be to put together from the many parts of the old Lego-Technik models and missing parts as far as still available to order. The „vintage kits“ should be restored as well as possible in their originality.

Well mixed and not complete Lego boxes

The photo shows a small part of the „excavated“ Lego boxes. At least the boxes were already roughly cleaned. What came out after the painstaking sorting and construction work, however, can also be seen again.

 

Nr. 853 Lego Car-Chassis

The number 853 is the car chassis. The kit was sold in the year 1977. It consists of 601 parts and finished construction about 52cm long and 22cm wide.

The model has a four-cylinder in-line engine with two-speed gearbox and cardan shaft to the rigid rear axle. The gearbox as well as the pistons are functional. Likewise, the steering works. The seats are displaceable in the longitudinal axis.

In this series, the rear axle was still rigid and equipped with a differential. The following picture shows the tidy, restored kit.

 

Nr.: 8860 Car Chassis

Out of 671 individual parts, the car is to assemble chassis number 8860. The set dates from the year 1980 and has a size of 46×19 cm. Here was compared to the 853er already much expanded. The rear wheels are hung individually and have a suspension. The engine sits behind and this time is a four-cylinder boxer. Again, there is a transmission with three stages.

The seats are adjustable in the longitudinal direction and the inclination of the seat back can also be adjusted. Again, a rack and pinion steering is installed.

The original packaging is still available and looks like this in the sorted condition:

 

Nr. 854 Lego GoKart

From 1978 comes the Lego GoKart No. 854. It has the dimensions of approximately 21 x 13cm and is composed of 206 parts. On realized functions there is a rack and pinion steering and a single-cylinder engine, with a functional piston. The rear axle is rigid and the shaft is connected via a transmission with the crank of the piston. According to data in the network, this model has now reached cult status, as it should be one of the first Lego-technology models ever. Here is the original packaging and especially the number 9 on the front still available, then the model in collector’s circles should be really valuable. Unfortunately, I can not meet either criterion.

Nr. 856 Lego Bulldozer

 

With the model no. 856, Lego has launched one of the countless construction vehicle models on the market. The bulldozer dates back to 1979 and consists of 370 parts. The base is 24x 11cm at a height of 14cm. Of the functions of the blade is tiltable, raised and lowered. Two chains on gears represent the connection to the bearing surface.

 

Unfortunately, here too, only the box without internal division is available from the original packaging.

 

Nr. 8848 Lego Unimog

The Unimog 8848 from the year 1981 measures just under 30x12cm at a base of 14cm. It consists of 398 parts. As a functioning technology here again the steering, the tilting cargo area, as well as a raised and lowered, and tiltable bucket available.

Unfortunately, the box is missing the interior, otherwise the model is complete. Apart from the here presented, complete kits are still some more available, but where unfortunately too many parts missing. But some flea market or online raid of lego parts will probably arise once again to complete these sets and to be able to fully incorporate them into a retrospective collection.

YouTube, and interesting technology favorites

This time, I’m not going to talk about a project or an „old equipment concept“, but would like to introduce some interesting users or their contributions from the YouTube portal. These are contributions from the field of computer, technology and science, which I personally like to look at.

First and foremost, I would like to mention the legend of modern computer history, which has fascinated me since my youth. The ComputerClub from WDR times with Wolfgang Rudolph and Wolfgang Back. The two moderators moderated the program Computerclub from the beginning of the 80’s to 2003 at Westdeutscher Rundfunk. In the topics, the two men are generally concerned with computers and peripherals, new developments in the field of electronics and present all sorts of things here. Many broadcast recordings are archived on YouTube, including by user janbras.

On 22 February 2003, the last broadcast was broadcast on WDR.

But the two protagonists have not given up the computer club and let him resurrect on July 24, 2007 on a German private broadcaster (NRW-TV).

However, the private broadcaster NRW-TV had to cease its operation in 2016 and so the program was Nr.186 recorded as the last in the studios of NRW.

But Wolfgang Rudolph has managed by fundraising to set up his own studio and now produces the CC2 from his private studio on his own.

In the background, a lot has changed, which confused the viewers and freaks a bit. Parallel to the broadcasts existed the page cczwei.de which was filled by both gentlemen. After 13.12.2016 suddenly a new page appeared. The new domain cc2.tv has been created. The now operates Rudolph alone. The domain cczwei.de continues to be operated by Mr. Back. He is assisted by Heinz Schmitz, who is now producing YouTube broadcasts with Mr. Back. Apparently, there were sufficient reasons for the gentlemen to part with years of community work. There never was an official explanation.

 

From the computer area, the guys from VirtualDimension report. They call their channel VD Hurrican and produce the formats: Virtual Worlds, Back in Time, Retroplay and On Site. The contributions are absolutely professional and mainly deal with home computers. With a lot of background information the old 8 and 16 Bit’er are presented here. Gameplay as well as fair reports and contributions from community events are also part of their repertoire. As an example here a link to the unboxing of an Amiga500 and its history. On the occasion of their 1000th subscriber on YouTube, they have published a 1000-subscriber special with a studio tour.

From the Australian continent, Dave Jones, also an inveterate technician, blogs. On his YouTube channel EEVblog, He also introduces electronic devices, explains their structure and operation. A special category in his channel are the so-called Mailbags. Here, Dave receives packages from people in the community who he opens in front of the camera and presents their content. This can be old computers and boards, or even new developments and prototypes of startups that are presented here.

 

A slightly different channel is that of an Englishman. He calls himself Photonicinduction and shows experiments with high performances. All sorts of appliances, such as vacuum cleaners, heating lamps, washing machines, loudspeakers, etc. are operated to the limit of their maximum performance data – and far beyond. The end of the device through destruction is the goal here.

X-Mas 2016

Merry Christmas to the visitors of the blog!

Now it is already two years, in which I feed the „technology and retro blog“ with contributions. Who would have thought that … By now some readers have strayed here and asked if I could introduce one or the other device here. Of course I will try to realize it if possible. Unfortunately, the rubric with the computers of the 80s is still empty. Here I still lack the „thread“, as I should process the whole – it floats me to every device before a small video in which the devices are to be shown in the living state. If someone has ideas for that … like.

I would like to say a big thank you to my colleague Mario Wehr, who provides me with the WordPress environment and thus offers excellent service!

In this sense: Merry Christmas and happy holidays!

Retro controller brand new

NES – Nintendo Entertainment System is certainly still a household name. It was the 8-bit game console from Nintendo, which was also sold in Europe in the mid-80s and had influenced the youth of the time. It is now a museum piece that already deserves the title „Retro“. Maybe for this reason, she begins to revive in the Retrogamergemeinde. For example, this year a remake of the NES in miniaturized form with modern technology and pre-installed games on the market.

dsc_2760Also via emulators for all kinds of platforms you can bring the old NES game titles back to life. In order to be able to serve these games „in the right way“ (of course, it is also possible with the PC keyboard or via the touch screen on the mobile phone), the company 8Bitdo Tech has launched the NES30 GamePad Controller. It is a wireless bluetooth controller which was modeled on the original NES controller. It is equipped with an integrated rechargeable battery that can be charged via a MicroUSB cable connection. The controller is designed to be configured as a PC game controller, as a joystick, as a Bluetooth keyboard, and as a USB joystick. This can be realized via five different modes. These modes can be selected by keyboard shortcuts during power up. The table below shows the different modes:

  Mode1 Mode2 Mode3 Mode4 Mode5
  Joystick BT-Keyboard iCade Emu-Touch USB-Joystick
Power ON START START+B START+A START+X Kabelverbindung
Blue LEDs are flashing 1x 2x 3x 4x

Wickie, Slime & Paiper

_20160611_185029
ISBN 3-205-98989-9

It does not have anything directly to do with technology, but perhaps fits under the title „retro“ as a post very well in the blog: A book for browsing memories of the 70s and 80s is the band „Wickie, Slime and Paiper“ by Susanne Pauser and Wolfgang Ritschl. The book was published in 1999 by Böhler-Verlag Wien. It is a printed summary of an online forum as a souvenir album for the children of the seventies. It mentions numerous products and fashions, television and radio programs that were up to date at the time and is discussed and commented by the protagonists of the forum, themselves children of the seventies. The print is accompanied by scanned images of posters, catalogs, advertising slogans.

Beware of electrical goods from the Far East

DSC_2196The other day I noticed with a cold-device connection cable that the cable sheath has come loose in the area of ​​the strain relief. The wires came out. By itself, this is nothing special, if not here, apart from the unusual colors, the unusually small diameter of the wires in the eye would sting.

DSC_2199
left: cable without CE marking right: standard cable
DSC_2198
Plug without any test marks.

Normally, such a jacket cable with 16A / 250V and a CE mark is marked on the plug. The cross section of the stranded wires is 1.5mm².  The cable here on the photo but an indication of 10A / 250V was printed and NO CE sign available. The strands have a cross section of less than 0.5mm² !! Who uses such a cable and for example operates a heater with it, then may not be surprised if a quick fire breaks out … Unfortunately, I can not understand with what device I got this cable included. But it does not conform to the valid standards and represents a danger in the enterprise. In any case: Keep away from such products!

The storm glass – the weather forecast

Some time has passed since the last blog entry. On the one hand, I put this down to a lot of work, both professionally and privately, so that a bit of the energy for blogging was missing. The last days is the beautiful weather to blame. I preferred to spend my time riding a motorcycle instead of sitting behind the PC … But I also got a little gimmick again.

IMG_3952
FritzRoy storm glass

A colleague told me about it and at a large Internet mail-order company, I quickly found it. It is a so-called „FritzRoy storm glass„.

A storm glass is known for a long time from the seafaring. There it was used to predict weather changes. The storm glass is a glass cylinder filled with two liquids and hermetically sealed. The fluids are usually camphor and alcohol in saturated form, which do not mix but form small crystals. The formation of these crystals is related to the weather change. For a long time it was believed that the crystals react to changes in air pressure. Recent research allegedly suggests that the crystals react to electromagnetic fields called sferics. These sferics are preferably formed in low pressure areas. Thus, the storm glass shows the approach of a low pressure area and thus the bad weather.

 

IMG_3956
Crystals as weather forecast

The table (from the CarloMilano user manual) shows the different crystal weather relationships.

Clear liquid The weather is sunny and clear
Flaky liquid It is cloudy. Precipitation is possible
Small flakes It is foggy or damp
Little stars A thunderstorm is coming up
Little stars on a beautiful winter day It will snow
Big flakes It is covered. Snow is possible
Many crystals on the ground There is frost
Crystals on the surface It is getting stormy

An old tin …

… from the fund of grandmother’s cottage is this instant powder can.IMG_3873

The post does not have much to do with technology this time, but I’ve noticed this tin can because of the age and the designer graphics from times gone by. That’s why a few pictures of it must come in here. You do not see that very often anymore.

As can be seen in the photo, the instant powder can is the packaging of Ovomaltine.

Ovaltine contains the ingredients barley malt, milk powder, low-fat / de-oiled cocoa, whey powder, glucose syrup, yeast and honey. From the names of the ingredients is also the name Ovomaltine together: ovum (Latin egg) and malt (English malt). The high proportion of malt gives the Ovaltine their typical taste. Like the powder of instant cocoa drinks, Ovaltine is ready to drink after being stirred into cold or warm milk. (Wikipedia)

According to online research, the tin dates from the years 1954-1961 and was apparently used by my grandmother as a storage container for mothballs 🙂IMG_3880
