Thanks everyone. jb-electronics: I draw my one, including the fuse and the shunt with traces for up to 5A continuous, filter following datasheet recommendation, i2c address smd jumpers and connectors for power and i2c. are you at Germany or the US? Take a look at the photo and let me know if you are interested. We can work something out. http://tobiasmugge.files.wordpress.com/2012/06/dscn4054.jpg http://tobiasmugge.files.wordpress.com/2012/06/dscn4053.jpg
Cobra007: I can definitely try that out! I know how the math should look like on the paper, but I have no idea how to implement this on the controller. I would think it uses a time interrupt to capture the measurements at at pre-defined rate, log some of the last readings.. and then what? If you give me some hint regarding a C implementation of the math I can start working on that! =) I searched for an arduino implementation but I could not find one that made me happy. Grahame: Nice, they even give you the source code! I'll have to login and take a look =) On 4 jun, 06:11, Grahame Marsh <[email protected]> wrote: > On 04/06/2012 00:05, Tobias wrote: > > > > > I am trying some R and C measuring designs on the breadboard but > > nothing too promising so far. > > Tobias, > > For capacitance you might look at these Elektor projects: > > Low > rangehttp://www.elektor.com/magazines/2011/april/pico-c.1738839.lynkx?tab=1 > > High > Rangehttp://www.elektor.com/magazines/2003/february/autoranging-capacitanc... > > In both cases they are not much more than a TLC555 timer (the design is > a bit fussy on which manufacture's 555 is used) that the controller > measures the period of and then calculates the capacitance. > > Project is looking good... > > Grahame -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
