I've got about 8 S4 bodies that I no longer want and can't be bothered to put on ebay.

I'm offering them in batches of 4, plus whatever's left over. Some might need a simples repair, I have some spare parts.

COLLECTION ONLY from 15 miles north of Cambridge.

If they aren't gone in 4 weeks then they go in the skip.

If you are interested then send me a PM saying why you would like them. Preference given to community groups and similar.

I repeat - NO LENSES.

If you wanted to make a cash donation to my beer fund, all well and good. If you don't, that's perfectly fine. It won't sway my decision.

You realise that by screwing the top surface to the bottom you totally undo any effect that the insulating layer has?

Forget the driver for the moment. Are these found (3mm?) LED tubes current or voltage driven? What current will they take?

The Dutch are correct.... 

BUT...the supplier will need to do extra paperwork. And if they aren't regularly doing it have probably decided it's just not worth the effort.

Doesn't the equipment which is being cable tied in place have cable running to it?

I've never been able to work out why that format is used, the first point failure is usually the screen potentially putting mic body at 50v etc.

I believe it was standard at BBC but they banned it years ago.

The screen coming out of the back of the Hellerman sleeve makes more sense to me.

 

If you look carefully you will see that the cable is not a flexible 'mic' cable but an installation cable, in this case FST. As such, there is no strain on the screen as the whole thing will be laced within the rack.

I've probably been responsible for the termination of over 50k cables, so 100k connectors, in this fashion and can't remember a single failure.

In 50years I rarely come across Pin 1 taken to chassis of the plug and have never done it. The only time I could see it might be advantageous is if the connectors were adjacent to something unscreened kicking out a lot of electrical or higher frequency interference. 

That's why the tag should ONLY be connected on equipment, so that the ground continues onto the connector and surrounds the termination.

I'll just leave this here...

Thanks all for the replies, I had a feeling it wouldn’t be quite as black and white as I thought! 
 

Really? There's doubt? It's very clear.

BS7671 states, in 521.11.201...

Quote

Wiring systems in escape routes  shall be supported such that they will not be liable to premature collapse in the event of fire.

...and in Note 2 to the above...

Quote

this precludes the use of non-metallic cable clips, cable ties or cable trunking as the sole means of support. 

BS7671 for fixed installations, and by extension BS7909 for temporary installations, contains various requirements that in the event of a fire all cabling and equipment is to stay where it was so as to not introduce additional hazards for the fire service.

So you'll also be in breach of your premises licence.

In all the service manuals they refer to a HAL506, however this is long discontinued. I had to replace a couple in some 250XT washes and if my notes are correct I used a  SM451R.

I have zero faith in the design team who try to cut costs and insist we have to accept what we are given.

Who is the client here?

What was the White Light fire effect ground row called?

You need a copy of "Technical Standards for Places of Entertainment" jointly published by the ABTT, the District Surveyors Association and the Institute of Licencing.

Carnets are easy. I used to deal with them on an almost weekly basis "back in the day".

Please clarify how many cameras you see being installed per pitch. And, if multiples, are you envisaging someone cutting between them as the match progresses, or simply streaming multiple angles and letting the viewer decide.

Putting a 90 degree elbow on the end to divert the air shouldnt be difficult.

Difficult, no. Able to guarantee it won't come off at speed when blocked, nearly impossible.

Compressed air has no place next to any body part.

I've now got the issue of deciding whether to stick with 10mm facets to match my others or spend just a little more to get 5mm facets which look better. First world problems hey.

Or unequal, and mounted horizontally!

Does your desk have Artnet/SaCN out? There are drivers out there that take in Artnet/SaCN and drive multiple LED 'universes'.

Also gives you the option to drive the LEDs from a PC with something like JINX.

But if the ramp is of any length, as a kindness to wheelchair users, make it shallower if you can! 

 

I have a colleague who has quite blunt views on 1:12 ramps...

1 in 12, per Building Regulations, is only acceptable for very short ramps. Anything longer and you are looking at 1 in 15, all the way out to 1 in 20.

Building Regulations section K is also worth a read.

Is there a battery anywhere?

 Good products, and consistent. Good communication too. Unsure if it’s against the rules to post them here directly 

Personal recommendations are OK.
