At this point my friend from th elighting crew would be saying "But it's a helical staircase, not a spiral ..." 😉

You're right about the remote using a 3-pin XLR, Tim. Having sent it down an audio snake (once) I don't recall hearing digital interference.

Big Clive (of course) has a video about making one.

Maybe the output that drives every 8th key or the input that reads them has failed. Is it a dedicated kekeyboard scanner/control chip or discrete logic?

Is this like what you were using?

I've been through that mill from the inside (as an employee). It's always a weird time.

Bit of a convoluted trail, I wonder if the change to LM 140121 is so that the new phoenix like Le Maitre isn't associated with the old, liquidating one?

Coming up as unavailable here.

I expect we'll see a lot more of this can kicking over the next couple of years.

Useful company, by the look of it, and just down the road from me. Thanks.

Apologies for sending you up a blind alley with those 8's ... I can only say if had been a long day and I'd done my code on shorts, not ints. Anyway, glad to hear it's working.

Well spotted, Dave, absolutely if should have been FFFFC000 - D'oh! It had been a long day. My test was as follows: inline short combine7bit(unsigned char high, unsigned char low) { unsigned short u = ((high & 0x7f) << 7) | (low & 0x7f); if (u & 0x2000) { u |= 0xC000; } return (short)u; } int main() { short s = combine7bit(0x78, 0x77); printf("%hd\n", s); s = combine7bit(0, 0x64); printf("%hd\n", s); return 0; } This outputs -905 and 100 for the given inputs.

My code returned 100 and -905 as a 16 bit short int and I can't immediately see the problem in your code. When I get back to the office tomorrow I'll do a cut and paste of my code. It used an inline function but that won't change the logic.

The forum has turned 0 x 2000 into 0 * 2000 - your code has the same mistake. That will stop it doing the sign extension. if(val&0*2000)val|=0xC000; replace the * with an x Also be aware of the length of the int - if it's a 32 bit int, you need the longer value to or with (0 x 8888C000) Also - strictly speaking, the test ought to be if ((val & 0X2000) != 0) val |= 0XC000;

Yes, the quick'n'dirty code I gave you assumes it's an unsigned 16 bit number composed of two 7 bit parts. I think you just need to sign extend the unsigned value you get ... So if you take the unsigned value you've got, call it u, then do if (u & 0x2000) u |= 0xC000; this sign extends your 14 bit number (because it was composed of two 7 bit numbers. This correctly returns 100 and -905 for your inputs. This assumes u is a 16 bit integer. If it's a 32 bit integer then you need to or with 0x8888C000.

As a member of an amateur troupe who have done shows in a couple of venues other than our own, I've not come across this. At Minack we've always had the choice of using their desk or bringing our own. when we were at Fairfield Hall (well, Ashcroft theatre) we were just pointed at the in-house desk and asked if we knew how to use it - yes, it was a Strand - and that was the end of it. We also supplied the follow spot ops, only one of whom had used a Super Trouper before, so they gave us a quick instructional and again, we were left to it. Part of the hire.

DrV is on the money, but a shift followed by an or might be faster and smaller e.g. int val = ( (rhHigh_part & 0x7F) << 7)|(rxLow_part & 0x7F);

The elation WW profiles go down to 19 degrees, although, I do wonder if a source 4 lens tube fits? A few manufacturers (e.g. Infinity) say they "accept industry standard lens tubes" which actually means ETC S4 tubes. Those go down to 5 degrees ...

How bizarre. Maybe they need to take a leaf out of the Minack book - they state in the conditions that it is the incoming company's responsibility - amateur or professional - to supply someone competent to program and operating the lighting (and sound) equipment, and that's the end of it.

On the occasions we've needed our Unique 2 looking at we've used Whitelight; they're a Look Solutions supplier.

fair enough. We found the chauvet profiles and fresnels were about the same cost range as the colorsources, hence my suggestion, The jrs are less expensive than the full size colorsource spots (and a lot lighter).

Colorsource jr? Similar size to a S4 jr, we have a load of them and we're pretty pleased with them so far.

This sounds very much like the sort of thing Pi-Presents would handle very well (hat tip to kitlane for telling me about this application). Fairly basic pi can be triggered by a button to play a video. Low cost solution, I'd have thought.

One thing to watch for if attempting to duct haze - and I agree with the others that a chilled fogger would be better - is for the vapour condensing in the tube, especially if it's glycol based. You'll need to keep clearing it or it will pool at the low points.

If you're sending audio separately, watch out for synchronisation problems, as there will be latency introduced in the video path.
