Project Ideas

Business

Mobile HV safety & diagnostics service

Offer an on-site service for dealerships, fleet operators, and independent shops that provides certified zero-voltage verification, insulation resistance checks, and potential-equalization testing. Use the module’s guided documentation to produce timestamped, exportable certificates for compliance and record-keeping. Position the service as fast, compliant, and convenient for organizations that cannot easily move vehicles to a central facility.


Technical training and certification program

Develop instructor-led and blended courses that use the module as the practical testing tool. Create curriculum modules around the device’s guided procedures and issue competency certificates tied to documented hands-on measurement logs. Sell training packages to vocational schools, OEM service networks, and independent repair chains.


Rental/subscription toolkit for independent shops

Provide short-term rentals or subscription access to calibrated HV measurement modules for independent garages and specialty shops that need occasional HV capability. Include shipment, calibration paperwork, technical support, and optional training. This lets small operators access compliance-grade testing without the capital expense of buying and maintaining equipment.


Fleet diagnostics & compliance SaaS

Develop a cloud service that ingests the module’s exported measurement logs and turns them into fleet-level dashboards, compliance reports, and maintenance triggers. Sell the software as a subscription that helps fleet managers schedule preventive maintenance, track calibration statuses, and produce audit-ready UNECE R100 compliance records.


Calibration and compliance lab service

Create a niche lab that performs factory-traceable recalibration, verification, and R100-conformant potential-equalization assessments for aftermarket installers and converters. Use the module’s calibration-friendly design to offer packaged services: instrument calibration, certificate issuance, and on-request rechecks tied to specific vehicle retrofit projects.

Creative

Hands-on EV training rig (safe demo)

Build a purpose-built, lockable training bench that mimics a hybrid/electric vehicle high-voltage subsystem using low-voltage simulators and inert mock components. Use the module’s guided procedures and documentation features to create repeatable classroom exercises (zero-voltage verification, insulation-check scenarios) so students learn workflow, reporting, and safety protocol without exposure to live HV. Export logs as class records and build progressive skill-checks.


Interactive diagnostics exhibit

Create a museum/makerspace display showing how EV safety checks work. Feed anonymized measurement logs into a visualization dashboard (graphs, timelines, animated wiring diagrams) and let visitors step through the module’s menu-driven procedures via a touchscreen. Add audio narration and simplified ‘what this test checks’ explanations to make the technology accessible to non-technical audiences.


Data-driven kinetic sculpture

Use exported measurement datasets (real or simulated) as control inputs for a kinetic sculpture or light installation. Map voltage/insulation values to motor speeds, actuator positions, or LED color palettes to turn diagnostic sequences into dynamic art pieces. Keep the sculpture electronics isolated and powered by standard low-voltage sources—use the module only as a data source (USB export) rather than connecting it to live HV hardware.


Certification poster series

Turn the module’s printable, timestamped measurement reports and calibration certificates into a limited-edition graphic poster series. Use the structured data (test timestamps, pass/fail results, calibration ID) to generate modern, tech-themed prints that tell the story of safety and precision—good for shop walls, trade-show booths, or gifts for graduating technicians.


Guided troubleshooting video library

Produce short, scenario-based training videos that follow the module’s guided procedures. Record the screen output and voiceover that explain each menu step and the interpretation of example measurement results. Package the videos with downloadable example log files so viewers can replicate each scenario on their own devices or in simulated environments.
