SparkFun Electronics Forum

I found myself wanting a dedicated power monitor to use while developing battery-powered application circuits, so I built one using the MSP430G2402.

This device has already helped me identify and eliminate about 40% of the power usage of a project in-progress.

Right now, I just have the code as a zip file on the download tab, but if anyone wants to develop additional features, I can check the code into Subversion and create some branches.

The board can be ordered for about $12 (for 3 boards) by uploading the Eagle .brd file to http://www.oshpark.com. I don't make any money from oshpark.

Neat!

Nice board and write up! I have a 430 laying around that just found a new purpose.

This would go over well at the 43oh.com forums too.

Good idea. I just posted it over there as well.

I submitted it to SparkFun to see if they wanted to make and sell them, but no go.

Have you considered tindie.com? It's vaguely like kickstarter, but smaller scale and very much focused on exactly this sort of thing.
