Hi,
I’m an electronics engineer and I often find that I want to measure a couple parameters (voltage, current, temp, maybe a few digital pins) over a few hours or days at a relatively low data rate. I often also want simple test automation (switch a load on – drain a battery; switch load off – observe charging cycle etc.). It seems like I should be able to set up this sort of test in a few minutes, but all of the existing data acquisition solutions I can find take considerable time to configure (write code for logger, get a shunt resistor for current measurement etc.) Also, many of the existing options have limited input ranges, and their gain doesn't scale automatically with input signal amplitude. Has anyone else found this sort of thing to be a problem?
Anyway, I finally got frustrated enough and just went and made the data acquisition / test automation device I wanted. I call it “Trendeca”, you can see the details here:
http://trendeca.com/If you have any feedback on the design, or have some other thoughts, I’m keen to hear them. Some of my engineering mates in the area wanted one, so I thought I would offer it to anyone who's interested.
Cheers,
Sean
