Meter specifications

[brentd]

I came across the IKEA hack using this code and was inspired to embark on a similar project myself!

I'm not an electrician, but always learning. Are there any specifications I should look for when picking out meters? Will removing the shunt usually bring meters like these into a range the Arduino can handle?

Here's one in particular I was looking at: http://www.ebay.com/itm/like/300684546360?lpid=82&chn=ps

Appreciate any help. Thank you for making this project public - I'll most likely end up writing the code myself as a learning exercise but will use this as a starting point.

Hi Brent,

Honored that you were inspired!

I don't remember too clearly about the meters; I think most meters are pretty low current full range without the shunt. I'll check with my brother – I did the software & he did the IKEAing. But my bet is that matter would work.

I checked with Matthew, and he agreed:

Yes, we definitely clipped the shunt on all the meters, and after that, the arduino was able to drive them all from PWM.

Good luck, and if you feel like sharing pictures once you're done I'd enjoy seeing what you build!

Thanks so much for the responses! I'll definitely share what I come up with.
