Original Protoboards mit Original Bauteilen und Anleitungsbuch.

Genau so macht man das heute.

Aber, gib zu, verstanden hat man bei den alten Kaesten wenig, nur nach Anleitung eingesteckt und wenn's nicht ging nach einigem Rumfummeln in die Ecke gelegt, denn leider waren die Anleitungsbuecher nicht wirklich verstaendnisfoerdernd. Ich hab vor 10 Jahren oder so die Philips-Buecher bis hin zum EE2007 Fernseher noch mal gelesen. Grauenhaft. Das ist heute leider nicht viel besser.

Das mag ja so sein, daß man Richter nett finden kann, aber was er zum Stromfluß dagt, ist schlicht falsch: "Dieses Wandern wird so lange in unveränderter Stärke fortbestehen, bis ein vollständiger Ausgleich zustande gekommen ist." Zwar fließt ein elektrischer Strom aufgrund einer Potentialdifferenz, aber nicht in unverminderter Stärke. Wir haben es vielmehr mit einer sinkenden Stromstärke aufgrund des Umstandes zu tun, daß mit fortschreitender Entladung ja auch die Spannung sinkt. Den genauen Verlauf kann man mit einer e-Funktion nachrechnen.

Heinz Richter ist Nostalgie. Rückopplungsempfänger baut heute keiner mehr, schon gar nicht mit Röhren.

Hello Walter,

Ah, the good old days. When I was 7 or 8 I had a Philips lab kit. EE75 or something like that in a blue/white box. The nice thing was that it consisted of real parts. And yes, that occasionally meant breaking off a lead of the precious AF116 and having to crack the piggy bank. Four Deutschmarks. Ouch. On the other hand one could add stuff from the regular electronics stores and try a totally different design.

Mounting was by means of spring contacts that you could insert into peg board. The springs were kind of strong so once the bleeding from various fingers had stopped you could then proceed to build a circuit from the booklet or later try out your own ideas. Marvelous. That's how I got into electronics.

I just wonder what's out there for today's kids. Anything? My impression is that there can't be much, considering that many newly minted engineers can't even solder (!).

Since it seems you grew up in Europe, do you remember all those little Franzis paperback booklets?

Regards, Joerg

Enter 82008 or 82024 as a PLZ and search for a electronic kit.

PS: JAJA deutsche NG.

Hello Mike,

Ah, now it worked. Nice. I think that is a good deal for 10 Euros. Walter, what do you think?

Bei Euch versteht aber doch jeder Ingenieur Englisch. Ich weiss nicht, ob Walter in Deutsch noch alles mitlesen kann.

Gruesse, Joerg

Aber AoE und der T-S sind ein ganz anderes Niveau. Mit den Bastelkästen habe ich angefangen, als ich etwa 10 war -- und sie kurz darauf zur Seite gelegt und lieber am C-64 den User Port demoliert[1].

Weitergemacht habe ich mit "64'er"-Elektronikkursen ("Hardwarebasteleien am C-64" war ein sehr gutes Buch, der Rest -- naja...) und Hobbythek- Büchern aus der Stadtbibliothek (im Rückblick: aargh!).

AoE würde ich selbst dem begabtesten Bastler nicht vor der Oberstufe zu lesen geben [2], den T-S eigentlich erst im Studium. Bleiben etwa sechs Jahre, für die es an guter Literatur mangelt.

[1] Modellbahnsteuerung, erster Versuch: Märklin-Weichen direkt an den Userport. Funktionierte ein paar Sekunden, dann war der CIA Schrott. 60 DM für einen neuen (inklusive Einbau) führen bei einem 11-Jährigem zu einem gewaltigen Lerneffekt... :-) [2] Nicht zuletzt deshalb, weil man AoE auf Englisch lesen muß. Die deutsche Übersetzung ist eine Strafe.

falsch, der Kosmos "Radiomann" wurde bereits im letzten Jahr neu aufgelegt und Audions mit Röhren werden noch zu hauf gebaut

Gruss Peter

Dann bitte ich vielmals um Entschuldigung. Das wußte ich nicht. Ich werde gleich morgen bei AVM nachfragen, wieviel heutzutage ein WLAN-Audion mit Röhren kostet und ob E-Plus so nett ist, mir zur UMTS-Flatrate ein passendes Endgerät auf Basis der PCL 85 zu liefern.

Röhrennostalgie kannte ich bisher nur im Zusammenhang mit Verstärkern.

Holger

PS: Aber lassen wir das mal. Professionell werden Röhren in kene Empfänger mehr eingebaut, die irgendwo vom Band laufen.

It looks like a nice basic kit. I look now and again in the stores for such kits, and nothing has ever come close to the Kosmos kits (I have them all!) from the 70's. I wish Kosmos would make them again (they have revived the Radiomann). I recently picked up a RadioShack "Electronics LearningLab" which doesn't look too bad.

The biggest difficulty I had with the kits was that they were in German (I found out much later that the kits were designed for youths several years older than I, I didn't know I wasn't supposed to understand it!). I learned a lot of German trying to figure them out, though the difficulties were compounded by using a German-English dictionary that did not include engineering jargon. I still am not fluent, and need help with Google translator now and then . I write in English because I can't express myself properly in German.

I had the chance to use this skill many years later when I found myself hired to port some engineering software to a Japanese computer, and all the manuals were in Japanese. I don't know any Japanese, but figured out the manuals anyway.

I still have the Grundkasten XG. It's in remarkably good shape, though the brass is corroded and the paper labels have yellowed and fallen off.

The effort in putting the Teil 1 online is my way of saying thanks to Kosmos and Heinz Richter for the fine kits they made and the fun I had with them. If they're online, they won't be forgotten. I am grateful to Kosmos for giving me permission to do this.

Hello Walter,

Did you mail order them or was your father stationed over there?

I can imagine how tough it must be to figure all this out while also having to learn the electronics side. I had a few of those experiences in my consulting career. An Italian client only had Italian docs. For some reason, every time I turned to the power supply page (unita d'alimentazione) I craved ravioli and wine. Then there was that oscillator project where everything was Portuguese, Brazilian style. And the folks in The Netherlands wouldn't allow me to document my design in English. No, it absolutely had to be Dutch.

Now we live in the US but things change here as well because this is California. The plumbing aisle at Home Depot is now also the "plomeria".

I don't have my Philips anymore. Sigh. Didn't survive all the moving. But it did not have a rigid frame like the Kosmos, more like a collection of parts.

No matter what people say I guess Heinz was someone who brought a lot of youngsters into electronics.

Regards, Joerg

Hallo Holger,

Mit dem Ergebnis, dass der HF Teil heutiger Radios in den meisten Faellen nichts mehr taugt.

Gruesse, Joerg

My father was stationed there. Many American families there at the time sadly would stick to the bases, but we were always out enjoying the sights and culture. The German toy stores were a special delight because the quality and sophistication of German toys (of which Kosmos is a fine example) were much better than the American fare. I still have a very nice Maerklin electric train. Some of the shops would also import the best of British toys, too.

These days in America, a lot of stores specialize in importing european toys, and American toys have gotten better, so the difference has evened out a lot. Out of safety fears, however, modern chemistry sets are a sad, pathetic joke.

The funny part is I naively didn't know it was supposed to be hard, and just waded right in and did it anyway. I've often thought this is why young people are the ones who make discoveries, they haven't heard yet that what they're trying to do is impossible .

I still get a craving for Springerle every Weinachten.

Kosmos

them.

Do people have bad things to say about him? I've looked at a couple of web sites devoted to his work, and it all looked good to me.

Hehe. In den siebzigern hatte ich Omas Dampfradio geerbt, von Max Grundig mit der üblichen Bestückung beröhrt. Damit hörte ich UKW sowie LW/MW/KW in guter Qualität. Kurz darauf kaufte ich mir eine billige Stereoanlage. Radio habe ich nach ein paar Versuchstagen weiterhin mit dem Dampfradio gehört...

Hello Walter,

Yes, the best thing you can do when stationed overseas is to live off base. It's the only way to get to know the people of a country. When I was a kid I sometimes helped an American who lived off base wash his huge Pontiac. Compared to that many German cars looked a bit like Tonka toys. Then we moved to the US and the first morning in our house we woke up to a loud roar. Ah, that was the sound of a genuine GTO that a neighbor had painstakingly restored.

Well, the usual. Like "Oh, this or that statement isn't 100% accurate". So what? He got kids into electronics, that's what matters.

WRT to toys I agree that Europe had better ones when it came to real hobbyist areas, where money is a secondary concern for those who take it seriously. But on the electronics front it was the other way around. In the US there was a Radio Shack even in the most remote town. When I needed a part in Germany that meant a lengthy train ride into Duesseldorf or scrap it out of some old TV. Now you see Radio Shacks here in the US closing. Ours just became a cell phone store. Sigh.

Regards, Joerg

I can't really comment about more remote places, but even when I got into electronics in the second half of the 80s, there were at least half a dozen small(ish) electronics stores scattered throughout Hamburg, plus Conrad -- and based on that, I'd expect at least one store even in a smaller (100,000 people) town.

At least two of those stores still exist, and still sell parts; others have either shut down or shifted their business entirely to PC components and/or mobile phones.

And in those stores that remain, it's getting harder and harder to find employees who actually know something about the stuff they're selling -- at least that's the situation with Conrad in Germany and Maplin's in the UK.

Hallo Andreas,

Danke. Sieht so aus, als waere meiner EE20 gewesen, denn das Bild kommt mir sehr bekannt vor.

Ich wusste nicht, dass danach noch so viele Speazialkaesten kamen.

Gruesse, Joerg
