Portable Industrial DAQ Prototype
Budget: $750 – $1,500 USD
I need a complete portable data-acquisition system. The unit must simultaneously log pressure, vibration, ultrasonic and TDC/RPM signals coming from piezoelectric sensors and a magnetic pickup, condition those signals onboard, digitise them with high-resolution ADCs, time-stamp the data, and store everything so it can be retrieved later over a simple USB connection in the field.
Field use means the hardware has to shrug off the elevated temperatures typically found around these machines, run from a small battery pack or 24 V plant supply, and sit inside a compact, rugged enclosure that can be tossed in a toolbox without worry. Component choices, PCB layout, and mechanical design therefore need to prioritise thermal performance, EMI immunity, and vibration resistance.
I’m looking for the full hardware path: schematic capture, PCB layout, BOM, firmware that drives the ADC(s) and manages the USB mass-storage interface, plus a first-run prototype assembled . Wherever possible, please leverage proven analog front-end techniques—charge amplifiers for the piezo inputs, anti-alias filters, isolated power rails—to keep the signal chain clean.
Deliverables
• Complete schematics (PDF & native CAD)
• PCB Gerbers, placement, and 3-D files
• Firmware source with build instructions
• Assembled, tested prototype with a short validation report showing channel accuracy and temperature soak results
If you already have experience combining piezoelectric sensing, low-noise analog design, and USB data offload in harsh environments, this project should feel familiar. Let’s discuss any smart ideas you have for making the unit smaller, tougher, or easier to use before we move into layout.
