Sorry for the shameless plug....
but I have so little time to work on my projects that it can take up to a year to get out something as simply constructed as the following. It has to do with my main hobby being electronics, and the hardware end of things is a bit rusty, so it takes me longer, and I really have my life filled to the brim (for the moment anyways) so the darned need to stay alive gets in the way too.
ANYWAYS, for those interested, I have finalized my polarized light skin cancer "revealer": take note, I warn this is not a medical grade device, and LOTS of training needs to be done before one can diagnose with such a thing, but it may help someone see an anomalous mole before it becomes cancer, and so if it does that for one person, I feel it was worthwhile spending 6 + months on it.
The IBLE can be found here...for any that are interested.
