A developer created a web-based simulator that recreates the experience of using a telegraph. The simulator allows users to input a message, which is then converted into Morse code and visually transmitted as flashing lights and audible clicks, mimicking the original technology. It also features a receiver that decodes the transmitted Morse code back into text. This project provides a hands-on way to understand and interact with the historical process of telegraphic communication.
A software developer has meticulously recreated the experience of using a 19th-century electrical telegraph, presenting their work online as "Telegraph Simulator." This interactive web application emulates the functionality and even the aesthetic of the original telegraph machines. Users are presented with a visually accurate representation of a telegraph key and a sounder. The simulator allows users to manipulate the telegraph key, sending and receiving messages in Morse code. By pressing and holding the key, users can generate the dots and dashes that comprise the Morse alphabet. These signals are then translated into audible clicks, mimicking the sounds produced by a real telegraph sounder. The simulator provides a text-based output of the decoded Morse code message as it's being received, facilitating understanding for those unfamiliar with the code itself. This allows users to learn Morse code interactively through practice and immediate feedback. The entire presentation is designed to evoke the historical context of telegraphy, giving users a sense of what it might have been like to operate this groundbreaking communication technology. Furthermore, the simulator highlights the fundamental principles of electrical signaling and coding that underpinned the telegraph's operation.

Hacker News users generally praised the Telegraph simulator for its simplicity, clean design, and accurate recreation of the Telegraph experience. Several commenters appreciated the nostalgia it evoked, recalling childhood memories of playing with similar toys. Some suggested improvements, such as adding sound or the ability to send messages between two simulated devices. A few users discussed the historical significance of the Telegraph and its role in communication technology. One commenter even shared a personal anecdote about their grandfather's career as a telegraph operator. The overall sentiment was positive, with many finding the project a charming and educational homage to a bygone era of communication.
The Hacker News post "Show HN: I Built a Telegraph Simulator" at https://news.ycombinator.com/item?id=43260251 has generated several comments discussing the project and the history/mechanics of telegraphs.
One commenter expresses admiration for the project, particularly the attention to detail in simulating the sound and feel of a telegraph. They mention the historical significance of telegraphy, highlighting its role as a precursor to the internet. This commenter also draws a parallel between learning Morse code and learning to program, suggesting that both involve mastering a new language to communicate with a machine.
Another commenter delves into the technical aspects of telegraph operation, explaining how the length of dots and dashes could vary depending on the skill and individual style of the operator, a phenomenon known as "fist." They also discuss the use of "Phillips Code," a shorthand system used by telegraph operators to speed up communication, further highlighting the nuances of the technology.
One commenter asks a clarifying question about the project, inquiring whether the user needs physical telegraph hardware to interact with the simulator. The creator of the project responds, explaining that the simulator can be used with a straight key or a mouse, offering flexibility to users.
Several commenters share anecdotes and historical information related to telegraphs. One recounts a childhood experience of encountering a working telegraph at a historical site, emphasizing the lasting impact of experiencing this technology firsthand. Another discusses the historical context of telegraph usage during wartime, mentioning its vulnerability to interception. Another still points out the role of telegraphs in the development of standardized time zones.
A few comments center on the practical applications of the project. One commenter suggests using the simulator as an educational tool to teach Morse code, highlighting its interactive and engaging nature. Another discusses the possibility of using the simulator for amateur radio communication.
Overall, the comments on the Hacker News post demonstrate significant interest in the telegraph simulator, with discussions ranging from technical details and historical context to potential applications and personal experiences. The commenters' engagement with the project reveals a fascination with the history of communication technology and an appreciation for the creator's effort in bringing this piece of history to life in a digital format.
