I fixed it!

Our second-hand Starbucks Barista blade grinder crapped our recently, meaning both that we were sad, and that we had gotten our money's worth for the $8 it cost us. However, it turns out, there's a recall! So, in a few weeks, we should have a brand-spanking new blade grinder.

In the meantime, though, we have all these COFFEE beans...

So, with my Goodwill Sense tingling, I popped into a local thrift store while on lunch from work, and found this!




With an average price over $80, the $7 I spent on it is looking pretty good. It wasn't working when I found it in the store, but I figured the innards couldn't be *that* difficult. Then, when I got home, I realized the screws had triangular holes! I took an old Dremel bit and ground it into a triangle shape, and eventually got something precise enough to loosen the screws. I replaced them with Phillips screws to make the next disassembly (which took place today!) easier. I bypassed something that was probably a breaker or fuse ("Safety? Whatever.") and now it works!

I just ground my first batch of primo Ruta Maya coffee, and it smells fantastic!

Normal pictures can only show about 7 EV (levels) of difference between the darkest and brightest part of a picture. This can make it hard to photograph things like a mountain sunset, since the sun is very bright but everything else is more than 7 EV away in the dark. By taking several pictures at different shutter speeds and combining them mathematically, it's possible to get a final picture where both the sun and the mountains are visibly exposed. This technique is called High Dynamic Range photography. The upper-left picture is the final result, while the other three show the range of exposures taken for reference. Notice that both the highlights of the darkest and shadows of the brightest originals are all present in the finished product. This picture shows details from over an 11 EV range squashed down to fit onto a normal computer monitor, which can only display about 1/2 of that dynamic range.

Thanks to Ryan Hayes for turning me onto this.
