By the way, Ladyada, the resistor CAPTCHA used for the comment form can be REALLY hard for people like me that are colorblind. With as much as 10% of the male population being colorblind, you may want to consider tweaking it. (And for those of you who might wonder how I check resistor values, I use a multimeter.)
@daniel, you posted a comment perfectly!
Further to Daniel’s comment, did you know that your resistor captcha is impossible to use on an iPhone?
@jason – hmm, we’ll check that out.
@adafruit, yeah, once I got a CAPTCHA that I could actually solve correctly. (Even this comment took several attempts to post. It’s a unique and interesting CAPTCHA method, but also very frustrating for me.)
Well, the Captcha works on My iPhone.
Just a quick not about posting a comment with an iPhone/iPad. There are 2 ways you can adjust the resistor values. First you can tap and hold for about a half second, the move the slider, and second you can zoom in and move the slider with 2 finders. I mainly use the first method, and usually always leave post with an iPhone or iPad. It might take a few tries to get it, but once you do it’s cake after that.
Now if could just work on my morning typing… :/
I personally love this captcha, it even uses html 5!
@jeremy thanks for the tips.
It’s a bit tricky to get it to work but here I am on an iPhone! The UI experience might be something to look into though.
