DIY Arduino calorimeter: Converting commercial thermally insulated coffee-cups into precision isobaric calorimeters.
Article in HardwareX, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
We present the design, construction, and validation of a low-cost digital calorimeter intended for teaching thermochemistry in chemistry, engineering, and life sciences curricula. The device repurposes a commercial 380 mL thermal container with integrated magnetic stirring, transforming it into a closed and well-insulated constant-pressure system suitable for calorimetric experiments. Temperature monitoring is achieved with a waterproof Dallas DS18B20 digital sensor interfaced to an Arduino UNO board, allowing adjustable resolution and automated data acquisition. Open source software provides real time graphical visualization, CSV export, and optional Windows executables for straightforward deployment. Compared to traditional educational calorimeters based on manual thermometry, this device offers improved reproducibility, elimination of reading errors, and enhanced student engagement through live data analysis. In contrast to professional-grade commercial calorimeters (US $15,000-100,000) and basic educational kits (US $50-500 without digital monitoring), our Arduino-based system (∼US $30 in components) provides an accessible middle ground that democratizes laboratory experimentation. Validation experiments, including neutralization and dissolution reactions, confirm reliable thermometric response, stable equilibrium detection, and enthalpy values consistent with literature. This open-hardware calorimeter not only broadens access to thermochemistry education but also serves as a platform for interdisciplinary training in electronics, programming, and laboratory automation, fostering early exposure to modern research practices.
