I’ve had enough people ask, while randomly meeting me as they walk down the alley, “hey, how do those solar panels work?” that I figured maybe a little object hyperlinking was in order. So I used bit.ly to create a QR code for my the public monitoring site for my solar, and made a little laminated poster, just in case I’m not there while someone strolls by with a smartphone. (Is there a better mechanism than bit.ly for this?)
I don’t know if anyone will actually snap it. But this seems like kind of a neat idea for solar evangelism, so any curious passer-by can get more info if they are interested…
BTW, you should really check out this 16 channel power meter made using open source tools:
http://www.delorie.com/electronics/powermeter
I have seen it. :) I actually made my own, with a bit less fabrication required, although it’s only 4 channels, based on the design at http://openenergymonitor.org
I wrote about it a little here, though I just realized I guess I never wrote up the final result…
In terms of actually creating a QR Code, there is qrencode http://megaui.net/fukuchi/works/qrencode/index.en.html
“Qrencode is a utility software using libqrencode to encode string
data in a QR Code and save as a PNG image.”
That’s a really neat idea. I would have probably had the link go to my server and then get redirected … just to be able to monitor the usage :)
Cool idea. BTW, bit.ly provides traffic reports on their shortened URLs. Just add a + to the end of the URL. Same trick works for goo.gl links.
I guess I’ve got that already; it links to https://bitly.com/cVdbW2+
Maybe I should get a more memorable short link ;)
Eric, this is a very cool idea! Can I steal it?
Kirk, of course, that’s half the reason I posted it. :)
