Elektor Digital The State of Hollow State Audio (E-book)
The State of Hollow State Audio in the Second Decade of the 21st Century Vacuum-tube (or valve, depending upon which side of the pond you live on) technology spawned the Age of Electronics early in the 20th Century. Until the advent of solid-state electronics near mid-century, hollow-state devices were the only choice. But following the invention of the transistor (after their process fell to reasonable levels), within a couple of decades, the death of vacuum tubes was widely heralded. Yet here we are some five decades later, and hollow-state equipment is enjoying something of a comeback, especially in the music and high-end audio industries. Many issues surround hollow-state audio: Does it produce—as some claim—better sound? If so, is there science to back up these claims? How do hollow-state circuits work? How do you design hollow-state audio circuits? If hollow-state equipment fails, how do you go about troubleshooting and repairing it? Can we recreate some of the classic hollow-state audio devices for modern listening rooms and recording studios? How can we intelligently modify hollow-state amplifiers to our taste? These and other topics are covered in The State of Hollow State Audio.

Elektor Digital Elektor Special: Power Supplies and Batteries (PDF)
Whatever the methods or even then financial means you have to make your circuits work, the power supply should rank high if not Number One in your considerations. The design block simply called “power supply” is hugely underrated both in electronics creation and repair. Yet, the “PSU” has enormous diversity and comes in wildly differing guises like AC/DC, generator, battery (rechargeable or not), PV panel, benchtop, linear or switch-mode, to mention but a few. The output ranges are also staggering like nano-amps to kiloamps and the same for voltages.This special covers the features and design aspects of power supplies.ContentsBasics Battery ManagementWhat to be aware of when using (Lithium) batteries.

Generic Six Digit Nixie Clock with IN-14 Tubes
Features Fully assembled and tested Nixie clock Six tested IN-14 Nixie tubes mounted to the clock base Two neon colon tubes installed into the clock base 12 V DC power adapter IR remote control Built-in proximity sensor User manual This clock is a combination of modern technologies and vintage Nixie tubes. It is a perfect gift for your friend and definitely will fit into any interior. Warm glowing of the neon will fill your house with soft orange light at night and will serve as a night light. The clock is built with 6 numeric IN-14 Nixie tubes. A built-in RGB LED backlight (with 10 levels for each channel) allow you to set your favorite color. Time accuracy is provided with built-in RTC (Real Time Clock DS3231) module and backuped with CR2032 battery while the clock is powered off. At the end of each minute (could be configured to be set from 1-5 minutes period or completely disabled) starts 'Slot Machine' feature that helps to prevent cathode poisoning effect. It scrolls over all numbers from 0 to 9. It is necessary to prolong tubes lifespan. Current date is shown each 1-5-th minute in 3 various formats: DD:MM:YY, MM:DD:YY or YY:MM:DD. The current time could be configured to 12 or 24 hour format. There are also three modes for colon tubes: Blinks once a second (is set as a default option) Permanently OFF Permanently ON The clock could be set to beep once an hour (when hour starts). The clock also has an alarm feature. All settings are stored in non-volatile memory (settings are restored after power-offs). Dimensions Height: 20 mm Width: 175 mm Length: 70 mm Tube height: 45 mm

Generic 4 Digit IN-12 Nixie Clock Kit
This Nixie Clock DIY Kit offers a captivating journey into the world of retro electronics and contains everything you need to assemble a luminous vintage-style masterpiece. At its heart are 4x IN-12 Nixie Tubes, whose mesmerizing neon light displays the digits with a charm reminiscent of the golden age of technology. Designed for enthusiasts who appreciate both artistic expression and technical challenges, this kit allows you to create something truly special. Each tube operates with an ignition voltage of approximately 170 V, generated by an internal boost circuit. Although this high voltage produces the characteristic glow effect, it also requires careful handling. For safety reasons, it is recommended to use a glass cover (not included) during testing and operation to shield the components and avoid contact with exposed wires. The assembly is as rewarding as it is complicated and requires a careful approach and a variety of tools such as soldering iron, solder, pliers, tweezers, multimeter, knife and screwdriver. This DIY kit contains all components including 4x IN-12 tubes and a remote control. Please note that the glass cover and base are not included.
