A new book titled 'The Secret Life of Circuits' has been published and is now available for order. The book serves as a practical reference guide to electronics and circuit design, featuring over 300 diagrams and illustrations in a full-color hardcover format, with orders shipping directly from the publisher and through major retailers including Barnes & Noble and Amazon.
A hobbyist built a modern 8-bit computer using recycled 1950s vacuum tubes, designed to run applications like an airship flight simulator and Fibonacci sequence calculations. The machine features a humanoid form with separate sections for arithmetic logic, control functions, and input/output, and requires careful thermal stabilization and safety precautions due to high-voltage operation.
An introductory explanation of electrical circuits, voltage, current, and power in computing. Voltage represents the push on charge, current is the flow rate, and power is their product. The article clarifies misconceptions using analogies and defines key terms like ground, Vdd, and decade for understanding how processors work at the electrical level.
