What It Is

Electronics Calculator is a web-based tool site for basic electronics calculations. Based on the crawled content, it currently mainly offers two calculators: Resistor Calculator, for reverse series and parallel resistor calculations; and Divider Calculator, for calculating a resistor voltage divider from a given input voltage and output voltage. The site is marked as version V1.0, with a 2018 copyright year, and is designed and maintained by Cristian Schlezinger.

Core Features and Developer Perspective

In terms of features and use cases, it is closer to a “small utility” for hardware development, electronics experiments, and teaching scenarios. It is suitable for quick estimates when designing resistor networks or voltage divider circuits. The pages do not disclose supported languages, frontend frameworks, formula details, nor do they provide an API, SDK, plugins, or integration information for EDA tools. As such, it is not a full developer platform, but rather a single-page or lightweight online calculation service.

Open Source, Self-Hosting, and Documentation

The licensing information is somewhat unusual: the page says it uses a modified “BEER-WARE LICENSE,” while also explicitly stating that no part may be copied without the author’s prior written permission. This means it cannot simply be treated as an open-source project available for reuse. The crawled content also does not include a source code repository, self-hosting deployment instructions, or contribution guidelines. Documentation is weak; the site even states that explanations will be added later. At present, it only provides very brief feature descriptions, lacking parameter explanations, examples, edge cases, and the basis for the calculations.

Pricing and Support

The page does not show any paid plans, subscriptions, enterprise edition, or payment methods, so in practical use it can be understood as a free web tool. The site mentions using Google Analytics and says it hopes to determine from traffic data whether it is worth covering the operating costs. In terms of support, no contact channel, SLA, issue feedback entry point, or maintenance schedule was found, making reliability and long-term availability difficult to assess.

Pros, Cons, and Who It’s For

Its strengths are clear positioning and a low barrier to use: open the webpage and you can handle common calculations such as resistors and voltage dividers. Its drawbacks are narrow feature coverage, insufficient documentation, reuse-unfriendly licensing, and the lack of API or ecosystem capabilities. It is suitable for electronics hobbyists, students, and hardware engineers who need a temporary tool for early-stage estimates. If you need batch calculations, auditable formulas, team collaboration, or integration into a development workflow, more mature electronics calculators such as Digi-Key or All About Circuits, or local EDA tools, would be better options.

Access from China

The crawled text does not provide information about access from mainland China, ICP filing, CDN usage, or network availability. Since the site uses Google Analytics, actual access experience may be affected by the network environment; this is therefore assessed as unknown.
