NanoTest – A Modular Testing System (Work in Progress)
I’ve been working on a hobby project called NanoTest—a universal, modular tester system that’s slowly but steadily taking shape.
The idea behind NanoTest is to create a flexible testing platform primarily aimed at production-line functional testing of electronic devices. It’s designed to handle a wide range of tasks, including:
- Voltage and signal testing
- Communication protocol validation
- Device emulation (e.g., I2C EEPROM emulation, UART device simulation)
- Ethernet frame testing
- CAN/LIN bus testing
- Microphone and buzzer verification
In many ways, it’s inspired by systems like PXI—but with a focus on simplicity, accessibility, and modularity.
What’s Next?
Right now, NanoTest is still very much a work in progress. I’m developing it in my spare time, refining both the hardware and software as I go.
That said, I’m starting to seriously consider taking this beyond a hobby and exploring it as a professional product.
If you’re interested in modular testing systems or have experience with production-line testing, I’d love to hear your thoughts.
Why Modular?
NanoTest is built around a modular architecture, meaning you only use the hardware you actually need. Different modules can be inserted depending on the specific testing scenario, making the system adaptable to various production environments.
Each module is:
- Galvanically isolated for safety and signal integrity
- Capable of real-time data acquisition
- Designed to integrate seamlessly with the rest of the system
Built for the Production Floor
One key goal is usability. NanoTest provides a ready-to-use GUI, allowing production-line operators to run tests without needing deep technical knowledge. The aim is to bridge the gap between powerful testing capabilities and ease of use.
