If the pi is clean, that condensation might as well be distilled, won't 
bother it a bit. The key is what we used to call lox clean though.

As I found last evening, having taken the rider and a 2 wheeled trailer 
over to the entry of this almost cul-de-sac and picked up about 4 cubic 
feet of dirt from a hillside slip trying to block the road and brought 
it back to try and fill some low spots in the back yard. I chopped up 
and installed half of it, then drilled about 25 holes in a tree stump 
that needs to go, and gave them a filling squirt of stump rotter powder, 
activated with the next rain in todays forecast. By then a PETA T-shirt 
was welded to my back. PETA around here stands for People Eating Tasty 
Animals. :)

Theres at least another "yard" of what passes for dirt there, so I can, 
if I last long enough running a mexican backhoe, level quite a  bit of 
my yards "potholes". The key is me and my years.

Well the first attempts to use had lots of hangs,
so i put the rpi in the 'ton yen' ( ice box)
to see if it would run longer than 10 minutes.

But,when I brought it out,
it beaded up with so much,
that I didnt try using it untill it was really dry again.
I found a big floor fan works well.
The unit has 3 heat sinks already.

Humidity here is 3x a day showers
and 3x a day changes of clothes
( peeling off t-shirts is a real exercise )

The humidity may help
but I'll keep the air circulating a lot.

Unless the heat-sink relies on sweating to work I very much doubt that
the humidity matters to the Pi.
In fact it probably helps: https://bit.ly/2LEMh1H

I have the heat sink kit installed, and an old video card fan rigged to 
blow on the sinks, no thermal probs, but its only 23.3C here, maybe 30 
peak in the afternoons, but the garage its in is air conditioned & stays 
at about 26C.

What Arm hardware platform are you running LinuxCNC on?  I'm just curious.

That's a bug in the buildbot webpage, thanks for the bug report.

The debs exist, but the URLs are wrong.  They should end with
"scratch-sim", not "scratch-rtpreempt".

I've updated the buildbot webpage with the correct URLs.

Hi TomP; I am running that uspace build on a pi3b (armhf) to run the 
Sheldon lathe.

deb http://buildbot.linuxcnc.org/ jessie master-sim

Working quite well and as stable as a block of granite these days. With a 
pinned rt-preempt kernel, the rest of it is kept uptodate from the 
armbian repo's a couple times a week, and I've not experienced the local 
event throwaway in 2 or 3 months.  Maybe one of the updates has fixed 
it? However arm64 has not been added to the buildbot to my knowledge as 
Sebastian has not found an affordable arm64 industrial rated board to 
add to the buildbot farm, as of maybe 6 weeks ago when I last asked.

Umm, thats new. Is it 2.7 something or master based? I don't have a 
2.7.build on any of my machines, master seems more stable.

Right, no arm64 yet. That I know of, so I've figured on building it 
myself if the pi dies. But the gpio setup on the rock64 is different, 
and the spi driver (rpspi.ko) is conditionally built to run ONLY on a 
pi3b, so thats the first thing that has to be fixed as it runs 40x 
faster that any linux spi driver.  So there are several roadblocks 
before a rock64 will actually move a machine, and that driver is the 
biggest one. That I suspect will take a coder well above my pay grade to 
fix. There is a bit of code about that can simulate a parport on the 
rock64's gpio, which can in turn drive the 7i90 interface, but no clue 
if its fast enough to compete with the faster (it writes 32 bit packets 
to the 7i90 at 41 megabaud, reads 32 bit packet responses at 25 
megabaud) this driver can do on the pi.

Thanks and take care, TomP.
