The Vibroplex Collector’s Page details the history and identification of Vibroplex semi-automatic telegraph keys, commonly known as "bugs." It traces the evolution from Horace G. Martin's 1902 Autoplex, which required a battery, to the fully mechanical Vibroplex patented in 1904. The resource explains how these keys generate automatic dots and manual dashes, helping telegraphers mitigate Repetitive Motion Disorder (RMD) and increase sending speed, thus improving their earnings. The site also covers the initial design by Alfred Vail in 1844, Jesse Bunnell's 1881 "Triumph Key," and William O. Coffe's 1904 "Mecograph." This page assists owners in identifying their Vibroplex models and determining their manufacturing dates, providing insights into the company's long history and notable figures like J. E. Albright. It notes that approximately 300,000 Vibroplexes have been produced since 1904, with the Original model still in production after more than 90 years. The resource also touches upon various Vibroplex models, including unusual, scarce, and common types, alongside legal and illegal clones from other manufacturers.

The **Nilex Morse Tutor** is an HTML5 web application designed to teach Morse code reception, adapting to user proficiency by adding new characters as readiness is detected. It prioritizes practice on less familiar letters, numbers, symbols, words, and phrases, while minimizing repetition of already mastered elements. The program offers multiple learning orders, including "Q7ZG..." (Ward/Jim's), "KMRS..." (PU5EPX/Koch), "KMUR..." (lcwo.net), "AENT..." (CWops CW Academy), "TEAN..." (Stephen C Phillips), "ANET..." (Vic VE3YT), and "ETI5..." (Ham Whisperer), alongside an alphabetical option. Users can customize the learning experience by enabling or disabling automatic progression, and selecting specific content categories such as numbers, symbols, words, phrases, QSO bits, Ham Radio Bands, X+Y=Z math, and units. Audio settings are adjustable for volume, speed (WPM), tone frequency, and keyshape/keying envelope, allowing for a personalized auditory environment. The interface provides visual feedback with blue bars indicating practice emphasis and gray bars for reserved characters, with clickable bars for manual character selection. Developed by "Nosey" Nick Waterman, VA3NNW, this tutor is based on earlier versions by Jim Wilson and a 1977 QST article. A significant October 2019 rewrite incorporated a new WebAudio sound library by AwesomeAidenW, improving offline functionality and mobile support. The content library was expanded to include 3000 top Google words, 2284+ General Service List words, ISO country codes, capital cities, US states, Canadian provinces, UK counties, common names, periodic table elements, quotes, Q-codes, electronic components, ham abbreviations, and example call signs. The software is distributed under the GNU GPL V2 license.

The CW typewriter is a compact adapter board that transforms Morse code into ASCII characters using an Iambic key. It connects to a computer via USB, emulating the keyboard. The device features inputs for Iambic keying and a WPM speed potentiometer, and outputs for a key and a speaker for side tone. The device can be used with various software and online typing games for practice, offering a unique and interactive way to learn and use Morse code.
