3oz of dried hops seems to be within the normal range for a dry hop, at least as far as i have seen in various recipes. it sounds like my idea of combining with a kit will do as i want though.

actually, definitely more grapefruit than anything else.

they are dried. they smell fairly citrusy to me, maybe fruity, grapefruit.

So, here is what I have to work with. Kinda new at this still, so looking for some ideas. 1) $25 gift certificate to midwest supplies for a recipe kit (extract). 2) about 3oz of unknown variety leaf hops from some plants at my parents place. 3) I like IPAs (especially northwest style). I was...

This is all good info :) I spent a lot of time trying to understand the math involved to figure out what would be appropriate for the application in regards to TEC power and heatsink sizes, but wasnt able to come up with any "ballpark" numbers (and didnt want to run through the rather...

the interfacing and control software is all mine, the web part using jquery-ui. the chart itself is from http://www.highcharts.com/

so far I have not. I added a more powerful fan to the cold side heatsink as well, and it actually got worse. This leads credence to the before mentioned problem of air leaks, but I so far have been working on other projects and have not spent any time trying to resolve that issue. I intend to...

the sensor on the external heatsink is just jammed between the fins. I dont yet have one on the interior heatsink, just the ambient sensor about 6" off the bottom in the middle. I was fairly careful with making sure there were no gaps in the insulation and used 45 degree wedges in some of the...

oh, you can see them in the 3rd picture in the original post. they are just to space the heatsinks apart from each other to match the wall thickness of the chamber.

just some 6061 flat bar stock that i cut to size and surfaced with sandpaper. used silver thermal compound between all thermal interfaces.

maybe that peltier module just has horrible efficiency. i mean, everything off ebay is high quality, right? ;) there are a few thermal interfaces that dont help with efficiency either, with the 3/4" aluminum blocks i added to make room for insulation between the heatsinks. at 25% power it is...

hmm, i am rather unimpressed with the photo gallery here, it resizes stuff down to useless levels and wont show the original image... the yellow line (interior temperature) is just touching the 60F line on the right. green (exterior ambient temp) is about 73F. red (hot side heatsink temp) is...

Well the new (extremely loud) fan has the heatsink temperature under control, but I am not terribly happy with the maximum temperature differential i am getting.

malfet, I got the h-bridge off ebay, but its the simple-h from robotpower.com
