Good news

James

Change into the astroberry-diy directory before running the second command?

James

Here's probably best:  https://github.com/WiringPi/WiringPi/releases

It looks as though Gordon is no longer developing WiringPi, so I imagine the github site will be the primary source now.

James

I think that means that you're not going to get anywhere unless you download the wiringpi source and build it yourself.  The existing one appears to contain references to functions in an incompatible release of glibc.

You may be able to ignore all of the other errors, which are only warnings anyhow, though it may be helpful if at least some of them are fixed.

James

Probably sensible, yes.

James

Try:

$ wget https://project-downloads.drogon.net/wiringpi-latest.deb
$ sudo dpkg -i ./wiringpi-latest.deb

?

James

There's this, too: https://github.com/WiringPi/WiringPi

I did try the autkor's site, drogon.net

Wow.  There's a blast from the past.  Back in the day Gordon Henderson and I used to hang around some of the same mailing lists (where "the day" was twenty years ago or more).

Yes indeed.  I won't call anything "Ultimate" or "Final" ever again!!!

Is that your final word on the matter?

James

I wonder if the focus is a little out?  Nice that you can see the difference in colours between Betelgeuse and Rigel though, not to mention the Hyades and Leo.

James

Would it be feasible to fit it on the north side of the warm room where it would be shaded from the Sun to help keep the temperature down?

James

At least it's only solid cloud.  We have rain here

James

Give Firecapture a  try, just to make sure the camera is functioning ok Gina.  <whisper>Or even oacapture, on a Linux box</whisper>

Really???  Where? What I've read so far would indicate considerable complication and difficulty.

I *think* this is the one I was originally looking at.  It looks kind of familiar, but I'm not at all certain at the moment.  Really annoyingly it appears that I neglected to take a copy of the URL when I added it to my list of possible future projects

But an ultrasonic wind detector is beyond me.

I refuse to believe it, Gina :D

I've seen some based around an Arduino that looked quite achievable, even for me.

That would be too far from the observatory and windage on the rig would put a lot of strain on the mounting plate and hence the woodwork of the observatory, I think.  Thanks for the suggestion though.

Yes, making sure it's adequately mounted on the wall would be the important bit.  If that's not possible then clearly it's a non-starter.  If it's designed to carry a satellite dish though, I imagine an ASC shouldn't present a big problem in terms of the wind.

A while back I was thinking of a combined ASC and wind instruments.  That still has certain appeal.  It means the weather station doesn't obstruct the ASC view.  Now I have a 3D printer with a 400mm x 400mm printing area that works well, I can make bigger prints than before.

Perhaps an ultrasonic wind speed/direction detector might be useful in that instance.  I imagine a rotating cup design might induce a fair bit of vibration.

James

You could possibly use a satellite/FM aerial mount such as this to avoid the roof?

I was looking at the older photo Gina, wondering if it might be less work to mount it on the western end of the warm room, so you wouldn't be cabling up to something that needed to move?

I now need to redesign the casing to make it totally waterproof - I don't want the next storm to destroy another camera.  As I see it, the main problem with waterproofing is cables.  I have grommets for round cables but ATM the motor cable is the flat type and the dew heater and camera cooling wires are single wires.  The other cable is the USB camera feed.  That is round but has connectors on both ends.  One answer might be to combine all the wires in one or maybe two large(ish) round multi-core cables or maybe I could "cheat" and seal the cables/wires with the ubiquitous hot-melt glue.

I'd suggest exterior grade silicone sealant rather than hot-melt I think.

James

They might be willing to tell you if you ask.  I  take it whatever writing is on the top of the IC is no longer legible?  Worth trying to get a macro shot to see if it's any clearer, perhaps?

James

Gina!  We spend so much time complaining about the rain and cloud, and now you're complaining because it's been too sunny!

Don't worry Gina the water will level itself

And if it doesn't you can always use it for waterskiing ?
