  1. Hi all Interesting read, this thread. Suspending things from underneath a helicopter is actually fairly straightforward, legally, providing the aircraft is fitted with factory-fitted or approved aftermarket sling hooks, and the load doesn't exceed the load rating of the helicopter, and the combined weight of the load, pilot, passengers and fuel does not exceed the all-up-weight of the aircraft, and the performance of the engine(s) and rotor system on the day (variable on things like the weather) are within limits. The hoop is suspending from two slings, but I'd suspect that if one snapped the other one would be strong enough to keep things attached. They're using a longline to keep the hoop out of the downwash from the rotor otherwise it would spin like a top, although there would be some wind irrespective of sling length. Once in the hover the airflow from the blades tends to be fairly laminar, which actually helps to stabilize what's underneath, providing it's not shaped like a wing. A human on a hoop is about as unaerodynamic as you can get. Sure it's been mentioned already but as she sits on the hoop you can see her attach a d-link with a steel cable to her belt to prevent her from falling out. For those that are interested, the helicopter they used is possibly an AS530. They have a rather unique shape to their skids. https://www.aircraft...-Sale/62698.htm All the best Timmeh
  2. Ah yes... but is it more reliable than a disasterpiece in a hot and sticky nightclub?
  3. New price? AFAIK the prelude and coda lines were discontinued years ago...

    Hi If you go onto Avo's website they still do the personality discs, writing your own .r20 isn't massively complicated and there are plenty of examples to see how the format works. All the best Timmeh
  5. Hi Theres half of it... https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F163643028783 All the best Timmeh
  6. Hi If you're triggering an MA2 the easiest thing to use is MIDI. My box does support bi-directional comms. It's made up of an ESP8266 programmable wifi jobbie that looks similar to an Arduino UNO - programming is easy and through their IDE. If you're interested, I wouldn't mind writing the code for you.

  7. Hi I have an ADA8000 bolted onto the back of my 01v96 desk and I honestly can't tell the difference between the audio coming of that and the desk itself. Even test tones sound fine with no distortion in the waveform. The only thing that really goes wrong on them like Sandall has said is the PSUs but it's trivial to replace the capacitors.

  8. Hi I've solved this issue by building buttons that run over Wifi and UDP. It transmits the button condition 10-16 times a second, so when its state changes you're guaranteed that at least one packet gets through. The range of the devices were about 50 ft between button to access point. The other end was a bit of c++ software listening for the packet state and firing off the appropriate MIDI command when it changed. All the best Timmeh
  9. Hi Nope - it will go sticky after being baked on with the heat. The only thing I would be tempted to use is molybdenum dry film lubricant. All the best Timmeh
  10. Hi I use light oil spray such as MechOil, and use it sparingly on the feature wheels. Irises should never be lubricated, because anything you add ultimately dries out and jams the petals together. I would avoid using PTFE spray as it tends to become very gummy over time which inevitably leads to problems. Optical components can be soaked in 100% isopropanol before air-drying. Be wary when removing the 700's diffuser assembly as it is extremely fragile, and the zoom lens must be fully forward before it can be slid out of the chassis. The kryptons are a much simpler affair, although care must be taken not to crush the wiring with the colour/gobo assembly when putting it back together. The focus worm drive can be lubricated with a few drops of 3 in 1. Belts can be lubricated with dressing spray. All the best Timmeh
  11. Hi Mike Ch38; we have four of them, that all misbehave. The 2 remaining AT3000 receivers are in the same rack, and are also in the same band, which don't suffer the same problem. All the best Timmeh
  12. Hi This may or may not be of any value, but here goes... I suffer the same issue with the G4 systems; after some investigative work involving oscilloscopes and RF analysis (at some cost) it turns out they can be atrociously susceptible to high-powered 2.4Ghz WiFi and 2.6Ghz 4G/LTE emissions; we upgraded from AT3000 series (which never had an issue) to AT3212 which was practically unusable because of drop-out and poor performance; so we swapped for G4s in the hope they'd do better. Sadly not. Even with pilot tone enabled the venue's wifi can easily overwhelm the receivers causing dancing RF meters when the mics are off, to dropout and crap range whilst they are on. The venue in question has Cisco access points that can transmit at a power far in excess of a hand-held microphone (or belt pack) and just love to hop all over the place, so much to the point that a 2.4Ghz wireless mouse and keyboard will pack up when the venue is full of guests, as will just about every 2.4Ghz radio mic that a visiting act has tried to use; I've seen an AKG Tetrad mic go titsup within 6ft of its receiver, and they are supposed to be bombproof. This is further backed up by the fact that when the venue is empty the interference is non-existant. Bottom line is you're probably experiencing Out of Band interference like I am; the solution is to use external bandpass filters tuned to the particular range that your mics work on, although these cost several hundred quid a pop, and the programmable ones even more. If you're not having issues with them on, then my advice would just be to ignore it, although I have to make sure that the desk channels are muted when not in use, for reasons like Paul has explained above. All the best Timmeh
  13. Hi Even Smart Dimmers cause issues; I had to deal with an install on a cruise ship that used (supposedly) pure-sine dimmers, that could be configured as hard power. 32 virtually brand-new, destroyed VL1000TSDs later, they decided it might not have been as good as they thought. All the best Timmeh
  14. Hi Have they really only got one universe available? If it's a single output desk I doubt they are using them in 16-bit dimming mode. What desk have they got? All the best Timmeh
  15. Hi Some rather cringe-worthy posts on my part from back then. MA1 on PC (up to desk version 6.606) will output MA-Net without any unconnected hardware, although capture will need to be on the same subnet for it to see the desk. MA2 does not, it requires at least one piece of hardware, be it an NDP, VPU, Network Dimmer or MA2 console before it spits out anything. I presume the change was implemented because it doesn't take a huge amount of effort to decode MA-Net v1 packets and once you've got the raw DMX, you can do what you like with it. I know that there were suppliers from China who, along with counterfeiting the entire console range, were building Artnet and DMX dongles that could be driven directly from onPC. If it's just for academic purposes, then I'm happy to say you can still download MA1 on PC from MA's website. All the best Timmeh
