The device I want making needs to monitor the output from a pair of loadcells or strain gauges,
Have you selected an instrumentation amplifier or will you need help with that? In other words, is it a programming only or programming and electronic design?
record the results
How much data? Timestamped? To a removable SD card? Or is the device to be completely self contained?
then download/transmit them to a laptop
Permanent storage is spreadsheet? Database? Text file?
for graphing in a simple spreadsheet.
Spreadsheet you made? The contractor is expected to make?
Excel? The Google spreadsheet application?
Look forward to hearing from you.
How? Email? Personal Message? Forum post?
