Note: You are buying a limited beta run. This does not mean you get an unfinished product. The hardware you receive is final hardware, however due to limited resources I do not have the opportunity to test my firmware and software on every possible computer configuration. As an introductory offer, I give you a $20 discount on the regular product price and in exchange you promise that if you find bugs or have feature requests, you contact me. Also I will ask you to fill out a questionnaire after about a month of use. All firmware and software upgrades will be provided free of charge, so after the beta period you will have a finalized product.
You might have come across USB power sensors on eBay - little USB-stick sized devices with a screen on it that tells you how many mA (and mAh) is flowing to some downstream device. What I'm selling is essentially one of those sensors on steroids. My USB-sensor has:
Essentially; this is a full replacement of a 2-multimeter setup PLUS convenient interface software for anyone developing USB hardware or developing apps and wanting to track down those nasty battery-draining code bugs.
This USB-sensor is the first sensor in a line of products under the series name MADPSU. I'm an engineer who mostly works in energy efficiency and IT equipment optimization. After fiddling around with LabVIEW and NI sensor boxes - which cost a fortune yet still require you to program essentially all analysis software - I figured I'd try designing my own sensor products. I initially designed this just for my own use, as I did most of my sensors. The USB-sensor was the first thing to make it to market simply because it's one of my simplest hardware products.
Also, this ties in with a very old project on my blog, which I called MADPSU or Measurable and Adjustable DC Power Supply - a PicoPSU-like product with in-built adjustable voltage regulators and accurate power sensing. Read more about the development of this project on my blog: http://ssj3gohan.tweakblogs.net/blog/6211/madpsu-a-measurable-and-adjustable-dc-psu-part-1.html. I even won an R&D prize for this!
The combination of high-precision, very fast-sampling hardware and incredibly versatile software makes this a one-of-a-kind USB power sensor. I don't know of any other project with similar specifications (which is of course why I built it).
