The story of the engineers who shaped the world's most powerful chip machines How do you transform a hopeless research and business activity into a billion-dollar machine and a world-leading company? The Dutch enterprise ASML pulled it off, and the book ASML’s Architects by renowned technology writer René Raaijmakers reveals exactly how. ASML's Architects travels back to the origins, struggles, success factors and sheer luck of a company that was barely alive at the beginning of the 80s, yet managed to become the uncontested world leader in chip lithography. Today, ASML determines the pace at which all information technology advances. The book covers the technology and the business, but the real story is in the people behind them. Throughout its pages, the interviewed engineers, scientists and managers speak frankly about their struggles, their fights and the grueling teamwork behind the scenes.

Create Models for 3D Printing, CNC Milling, Process Communication and Documentation Engineers dread designing 3D models using traditional modeling software. OpenSCAD takes a refreshing and completely different approach. Create your models by arranging geometric solids in a JavaScript-like language, and use them with your 3D printer, CNC mill, or process communication. OpenSCAD differs from other design systems in that it uses programmatical modeling. Your model is made up of primitives that are invoked using a C-, Java- or Python-like language. This approach to model design is close to the “mechanical work” done in the real world and appeals to engineers and others who are not a member of the traditional creative class. OpenSCAD also provides a wide variety of comfort functions that break the 1:1 relationship between code and geometry. This book demonstrates the various features of the programming language using practical examples such as a replacement knob for a LeCroy oscilloscope, a wardrobe hanger, a container for soap dispensers, and various other real-life examples. Written by an engineer with over 15 years of experience, this book is intended for Linux and Windows users alike. If you have programming experience in any language, this book will have you producing practical three-dimensional objects in short order!

Elektronica moeilijk? De titel van dit boek geeft het antwoord! In deze 3-in-1-band wordt de elektronica vanuit de praktijk benaderd. Dat wil zeggen veel praktijk in de vorm van experimenten en een minimum aan theorie. Zo raakt u stap voor stap vertrouwd met de behandelde onderwerpen. Daarbij ontstaan gaandeweg ook een flink aantal praktisch bruikbare schakelingen. Het gaat bij de elektronicahobby tenslotte om het bouwen of uitdenken van allerlei praktische of leuke schakelingen. Aan het eind van elk deel is een aanhangsel opgenomen met aanvullende informatie en de gegevens van een groot aantal elektronische componenten, zodat na dit boek ook eigen ideeën en experimenten kunnen worden aangepakt. In deze 3-in-1-band zijn de eerste drie delen uit de serie “Elektronica echt niet moeilijk” samengevoegd: Deel 1: experimenten met gelijkstroom Deel 2: experimenten met wisselstroom Deel 3: experimenten met digitale techniek

Eén ding hebben alle elektronische schakelingen en apparaten gemeen: de werking ervan staat of valt met de voeding. Alleen al daarom verdient deze deelschakeling speciale aandacht. Dit boek behandelt principes en schakelingen uit de praktijk van de voedingstechniek. Geheel in overeenstemming met de huidige trend gaat de auteur in het bijzonder in op 'mobiele' voedingen en op de techniek van schakelende voedingen. Ook wordt aandacht besteed aan het feit dat constante-stroombronnen ten opzichte van spanningsbronnen een steeds belangrijker rol gaan spelen. Naast de vereiste theoretische achtergronden en principes voor het ontwerpen en bouwen van eigen voedingsschakelingen biedt dit boek ook praktische toepassingsvoorbeelden, zoals het vervangen van defecte nettransformatoren, de voeding voor elektronica tijdens fietstochten of het aansturen van LED‘s in de verlichtingstechniek. Auteur Franz Peter Zantis is afgestudeerd als ingenieur communicatietechniek en houdt zich als elektronicus bezig met energie-installaties. Tijdens een onderzoeksproject heeft hij zich grondig verdiept in de stroomvoorziening van zelfstandig werkende apparaten en hij heeft talrijke artikelen over schakelende voedingen gepubliceerd.

Selbst für so manchen an der Elektronik Interessierten ist die Röhrentechnologie ein technischer Anachronismus, Röhrenverstärkern könne doch allenfalls noch ein Ehrenplatz im Museum zugewiesen werden. Das ist einerseits durchaus richtig, Röhren haben eine fast hundertjährige Geschichte hinter sich. Seit der Erfindung des Transistors, der Öffentlichkeit vorgestellt am 23.12.1947, war das Ende der Röhrenära eingeläutet. Von da ab sollte es immerhin noch mehr als zwanzig Jahre dauern, bis die Röhren – von Sonderanwendungen abgesehen – aus dem Blickfeld des durchschnittlichen Elektronikgeräte-Konsumenten weitgehend verschwunden waren. So gesehen, sind Röhren tatsächlich veraltet, haben Röhren Museumcharakter. Niemand käme wohl heute auch mehr ernsthaft auf die Idee, sein leistungsfähiges Digitalmessinstrument gegen ein Röhrenvoltmeter auszutauschen; hochintegrierte Halbleiterchips können nun einmal bei eigentlich unvergleichlich geringerem Platz- und Energiebedarf mehr. Auf die Überlegenheit moderner Mikroprozessoren in Bezug auf Rechengeschwindigkeit und Speicherkapazität braucht man eigentlich gar nicht zu verweisen. Der erste programmgesteuerte Elektronikrechner Eniac im Jahre 1945 wog rund 30 Tonnen, enthielt neben insgesamt etwa 500.000 übrigen Bauteilen 18.000 Elektronenröhren und füllte eine mittlere Halle. In einem Bereich allerdings, im Bereich der Audio-Signalverarbeitung, haben Röhren bei Kennern und Musikliebhabern ihre Bedeutung bewahrt oder zurückerlangt: Für eine mittlerweile gestiegene Zahl kritischer Hi-Fi-Hörer steht "ihr" Röhrenverstärker im Zentrum der heimischen Anlage und für unzählige Musiker ist der Gitarrenröhrenverstärker nach wie vor ein Garant für guten Sound. Dieses Book spricht jeden an, der sich für Röhren aus den verschiedensten Gründen interessiert, den "Audiophilen" ebenso wie den aktiven Musiker und natürlich auch den, der einfach nur etwas über die Geschichte und die gegenwärtige Anwendbarkeit von Röhren wissen will. Aus diesem Grund hat der Autor sowohl Informationen über ein interessantes Stück Technikgeschichte als auch – praxisorientiert – Schaltungen und Selbstbauanleitungen zusammengetragen.

All you need to know about good acoustics and sound systems in performance and worship spaces! Everyone knows that the ability to hear music in balance and to understand speech is essential in any space used for performance or worship. Unfortunately, in the early 21st century, we find that buildings with good acoustics are the exception rather than the rule. Much of the fault leading to this result can be traced to the widespread perception that acoustics is a black art. In fact, scientific acoustics as developed in the last century is a well-defined engineering practice that can lead to predictable excellent results. A basic, non-engineering understanding of acoustics will help building owners, theater managers, ministers and teachers of music, performers, and other professionals to achieve their goals of excellent acoustics in venues with which they work. Performers having a basic understanding of acoustics will be able to make the most of the acoustics of the venue in which they perform. This book helps those responsible for providing good acoustics in performance and worship spaces to understand the variables and choices entailed in proper acoustic design for performance and worship. Practicing acoustical consultants will find the book a useful reference as well. The level of presentation is comfortable and straightforward without being simplistic. If correct acoustical principles are incorporated into the design, renovation, and maintenance of performance and worship venues, good acoustics will be the result.
