Tweeker,
this may help - I also find it annoying to learn a
new user interface for every forum.
(Solution, join only the best forum around - this one :-)

Above the compose window is a row of icons...
including a smile face and undo and redo icons....
and a paper clip icon. Click on it.

A File selection dialog will open.
Once you have uploaded files,
(in my experience), you need to go
to the icon again and choose Insert All.
then you will see the ATTACH markup
in the text, and can move it around.

Hope this helps.
Sorry if this is wasted bandwidth.
Seth

You have to start with nice large pics.

If you go through some of the pics, you'll see that there is a maximum size, beyond which the blog software will reduce the screen pic size and give you a couple of 'handles' to click on that will show you the full size item.

I generally try to keep the pic size smaller than the 'resize' limit.

But if you are asking how I do centered, in-line pix, here's a link I posted as to how I do it.

Hope this helps.

found a quick article on re-purposing treadmills to power tools
Use a Treadmill DC Drive Motor and PWM Speed Controller for powering tools

Portland area seems to have more than a few used treadmills that i'll be looking around at this weekend along with maybe an AC unit.

AC, if you feel like parting with one of your lower end compressors I might be able to make ya a deal there too.

Hopefully it turns out?

Froze the outside of the plastic test container.

tweeker · 05-09-11, 10:39 AM

Test this weekend showed 9,426 BTU's @ 420 Watts of power, of which 50 of those watts were from my 12 Vdc water/fluid pump running of from a solar charged battery.

Tweeker, when people do this for cooling the water in their computers they put the whole assembly in a cooler.

That figures to a COP of 6.6

That's pretty high. I hit COP near that a fews time, and then only momentarily.

I'd be interested to know the details of your test.

Hi AC,

I figured how to post some photo's.

I don't have the test sheet in front of me, but this is the jist of it:

FWIW - Ambient Temp 68 degrees

Basically I was pumping/circulating 50 Gallons of water to/from tanks/exchangers per Hour, plus the 2.5 lbs of water in the lines = 419 Lbs of water

Temp Out of the heated tanks was 102 degrees

Temp Into the compressor tank (and then into the Condensor tank) from the heat exchangers was around 79.5 degrees.

419 Lbs X 22.5 degrees = 9,427.5 BTU's

I think I figured it correctly ?
