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.

Menno van der Veen is well known for his research publications on tube amplifiers used in audio systems. In this book he describes one of his research projects which focuses on the question of whether full compensation for distortion in tubes and output transformers is possible. In the past, a variety of techniques have been developed. One of them has largely been forgotten: trans-conductance, which means converting current into voltage or voltage into current. Menno van der Veen has breathed new life into this technique with his research project titled “Trans”. This book discusses all aspects of this method and discusses its pitfalls. These pitfalls are addressed one by one. The end result is a set of stringent requirements for Trans amplifiers. Armed with these requirements, Menno then develops new Trans amplifiers, starting with Transie 1 and Transie 2. These DC-coupled, single-ended tube amplifiers have unusually good characteristics and are suitable for hobbyist construction. Next the Trans principle is applied to amplifiers with higher output power. A trial-and-error process ultimately leads to the Vanderveen Trans 30 amplifier, which optimizes the features of Trans. The characteristics of this amplifier are so special and unique that Menno believes he has struck gold. To ensure that variations in tube characteristics cannot interfere with optimal Trans behavior, Menno makes use of simulations and comparison with other amplifier types. This book reads like an adventure story, but it is much more – it is an account of solid research into new ways to achieve optimal audio reproduction.

Temporary Delay in the Delivery of Unitree Robots Like many other suppliers, we are currently experiencing delays in the delivery of Unitree robots. A shipment from our supplier is currently held in customs, which has unfortunately led to later-than-planned deliveries for previously placed orders. We are actively working with our supplier to resolve this issue and expect more clarity soon, but at this time, we cannot provide any guarantees. Additionally, a new shipment is already on its way, though it will take some time to arrive. Since other suppliers are facing similar challenges, switching to a different provider is unlikely to result in a faster solution. Our top priority remains fulfilling existing orders. If you have any questions or would like to update your order, please do not hesitate to contact our customer service team. We will keep you informed of any further developments. Unitree Go2 series consists of quadruped robots for the research & development of autonomous systems in the fields of human-robot interaction (HRI), SLAM & transportation. Due to the four legs, as well as the 12DOF, this robot can handle a variety of different terrains. The Go2 comes with a perfected drive & power management system, which enables a speed (depending on the version) of up to 3.7 m/s or 11.88 km/h with an operating time of up to 4 hours. Furthermore, the motors have a torque of 45 N.m at the body/thighs and at the knees, which also allow jumps or backflips.

Practical Low-Cost Methods for Reliable PCB Production This book explains how to carry out reliable SMD assembly using affordable tools and small-scale equipment. It follows the complete workflow step by step, including tool selection, solder paste handling, stencil use, component placement, reflow methods, inspection, and rework. The focus is on bench-level and small-lab production rather than industrial assembly lines. It shows practical methods for building single and double-sided SMD boards with repeatable results. Topics include solder paste and flux, temperature profiles, hot air and hotplate techniques, small reflow ovens, inspection methods, and defect correction. Checklists and example workflows are included to help reduce errors and improve consistency. Key features: Tools and supplies for SMD assembly and rework Solder paste types, storage, and handling Stencils and paste application methods Pick and place workflow and component orientation Temperature profiles and reflow methods Hot air, hotplate, and reflow oven processes Inspection and quality control Common defects such as tombstoning and solder bridges Practical rework and component replacement Bench-level professional workflows and checklists This book is designed as a practical bench reference for anyone who wants to assemble and troubleshoot their own SMD boards with reliable results.
