## What it is
Pocket Science Lab (PSLab) is an open-source hardware and software ecosystem that turns a phone or desktop into a portable science lab with instruments like an oscilloscope, multimeter, logic analyzer, wave generator, and programmable power sources. The cross-platform app (written in Dart/Flutter) connects to the PSLab board over USB to run experiments and read sensors without coding.

## Use cases
- turn my phone into an oscilloscope
- measure voltage and resistance with a multimeter app
- log sensor data like temperature and air quality
- generate waveforms for electronics experiments
- use a logic analyzer on the go
- run science experiments in the classroom without lab equipment
- read I2C sensors from a portable device

## When to choose
- you need affordable portable lab instruments for education or hobbyist electronics
- you want open-source hardware and software you can extend with custom sensors, plugins, or firmware
- you want one toolchain across Android, iOS, desktop, and web

## When to avoid
- you need professional-grade high-bandwidth oscilloscope or logic analyzer specifications
- you don't want to buy the PSLab board, since the app is useless without the hardware
- you need wireless connectivity today, as it is still under development

## Facets
- artifact type: application
- maturity: active
- function: gui, data-visualization, sdk, plugin-system
- domain: education, hardware, developer-tools, cross-platform
- platform: windows, cross-platform, python
- tags: open-hardware, oscilloscope, multimeter, logic-analyzer, wave-generator, sensors, data-logger, flutter, science-experiments, instrumentation, android, ios, macos, linux, web
