The Raspberry Pi 5 case is a refinement of the Raspberry Pi 4 case with improved thermal features to support the higher peak power consumption of the Raspberry Pi 5. It integrates a variable speed fan that is powered and controlled via a dedicated connector on the Raspberry Pi 5.
Ook in deze tijd klinken buizenversterkers nog steeds fantastisch, misschien wel mooier dan ooit. Nu hebben we immers de beschikking over moderne materialen als ringkern uitgangstransformatoren, uiterst hoogwaardige weerstanden en condensatoren en vele soorten goed klinkend draad. Ook de moderne geluidsbronnen als de CD speler en de nieuwste hoogwaardige luidsprekers laten beter dan ooit horen hoe goed de buizenversterker weergeeft.
Dit boek van Menno van der Veen kijkt niet alleen theoretisch naar buizenversterkers, maar vooral ook naar de ontwerpfase waarin besluiten moeten worden genomen over de doelen en eisen van de versterker. Hoe hangen deze samen met subjectieve en objectieve criteria? Welke schakelingen klinken vooral prachtig en waarom doen ze dat? Stel dat je een versterker gaat ontwikkelen en in de handel wilt brengen, tegen welke problemen loop je dan aan? En wat te zeggen van het belang en de betekenis van metingen? Zeggen ze nu iets of zeggen ze niets? Dankzij de grote rekenkracht van de computer kunnen we tegenwoordig dieper meten dan ooit. Hoe pas je deze technieken toe bij buizenversterkers? Tot nu toe waren metingen over frequentiebereik en vermogen en vervorming voldoende om een beeld van de eigenschappen van een versterker te geven. Maar zijn zulke metingen voldoende of moeten we gaan meten zoals ons oor waarneemt, met echte muzieksignalen in plaats van meettoontjes? De auteur schetst een toekomst waarbij meten aan de versterker de eigenschappen van ons horen moet volgen om tot nieuwe inzichten te komen.
Dit boek is meer op de praktijk gericht dan op de theorie en heeft een beschouwend karakter, alsof de auteur van bovenaf naar de buizenversterker kijkt. Kenniselementen worden geïntegreerd en in een breed overzichtelijk kader geplaatst.
Understanding and Using Them Effectively
What happens in electronics is invisible to the naked eye. The instrument that allows to accurately visualize electrical signals, the one through which the effects of electronics become apparent to us, is the oscilloscope.
Alas, when one first ventures into electronics, it is often without an oscilloscope. And one is left fumbling, both physically and mentally. Observing an electrical signal on a screen for the first time is a revelation. Nobody wishes to forgo that marvel again. There is no turning back.
In electronics, if one wishes to progress with both enjoyment and understanding, an oscilloscope is essential. This marks the beginning of a period of questioning: how to choose one? And no sooner is that question answered than a whole string of others arises, which can be summed up in just one: how does one use the oscilloscope in such a way that what it displays truly reflects the reality of the signals?
Rémy Mallard is a passionate communicator with a gift for making complex technical subjects understandable and engaging. In this book, he provides clear answers to essential questions about using an oscilloscope and offers a wealth of guidance to help readers explore and understand the electrical signals behind electronic systems. With his accessible style and practical insights, this book is a valuable tool for anyone eager to deepen their understanding of electronics.

Was in der Elektronik geschieht, ist mit bloßem Auge unsichtbar. Das Instrument, mit dem sich elektrische Signale präzise visualisieren lassen und die Effekte der Elektronik für uns sichtbar werden, ist das Oszilloskop.
Leider wagt man sich beim Einstieg in die Elektronik oft ohne Oszilloskop vor. Man tappt dann im Dunkeln, sowohl praktisch als auch gedanklich. Die erste Beobachtung eines elektrischen Signals auf einem Bildschirm ist eine Offenbarung. Niemand möchte dieses Erlebnis danach noch einmal missen. Es gibt kein Zurück mehr.
Wer in der Elektronik mit Freude und Verständnis vorankommen möchte, braucht unbedingt ein Oszilloskop. Dann stellt sich zunächst die Frage: Wie wählt man das richtige Oszilloskop aus? Und kaum ist diese Frage beantwortet, tauchen bereits die nächsten auf, die sich letztlich auf eine zentrale Frage reduzieren lassen: Wie nutzt man das Oszilloskop so, dass die Anzeige die Realität der Signale korrekt widerspiegelt?
Rémy Mallard ist ein leidenschaftlicher Vermittler komplexer technischer Themen mit dem Talent, diese verständlich und fesselnd zu präsentieren. In diesem Buch beantwortet er wichtige Fragen zur Verwendung eines Oszilloskops und bietet zahlreiche Anleitungen, um die elektrischen Signale elektronischer Systeme zu erforschen und zu verstehen. Dank seines verständlichen Stils und seiner praktischen Einblicke ist dieses Buch ein wertvolles Werkzeug für alle, die ihr Elektronikwissen vertiefen möchten.
