  1. Hi Dalton, Thanks, very interesting! Do you have experience with mics/transducers of this brand?
  2. hi all, for a wildlife documentary, i am researching possibilities for longtime mic-installations in full out weather... as this sounds like quite a contradiction, i wonder if anyone of you has experience to share regarding this topic. the mics ( at least the capsules ) will be high up in trees, installed by crane, as are some endoscopic cameras. everything is cabled down to ground for signal, powering etc. once breeding season starts, we cant get close anymore. i am posting in the diy section, because i think the solutions from the shelf will not work here....
  3. wish list.... - a10 mini tx - the 24-bit-signal of a sonosax micpre/ad being wirelessly transmitted by a recording digital TX. All in a small, remote controllable package for boom-tip mount. And running on two or three AAs... todays wireless boom solutions sound very ok. but nothing like a good old cable, as advertised by some. there is room for improvement....
  4. if there was neverclip in the phantom version, it would be such a nobrainer for wireless boom work. maybe it is also without neverclip. so small and light. are these transmitters already out in the wild for real world feedback ?
  5. hi jez, it's not exactly recent. it ran on bbc4 some 10 years ago. try this channel. http://www.dailymotion.com/AlchemistsOfSound m
  6. not specifically related to fieldrecording, a bbc doc called "The Radiophonic Workshop" .
  7. guess its the same as bostik/prestik. its widly used here to stick mics ( amongst other... ) to almost any uneven surface. consists of polyisobutylene
  8. Hi Jesse just wrapped a 5 weeks shoot with the mini. cant comment on how well it is holding the timecode internally, i went the tentacle route (one always on my deva, one always on the mini). these boxes are perfect for the small alexa mini rigs and they hold timecode incredibly well ( less than 0.1 frames drift after a 12 hours day ...). as mentioned, the tc connector on the mini is placed less than ideally, i had to make a small profile, right angled lemo plug. all in all a breeze with this setup.
  9. To tape down stubby/short chest hair i found a tape called Mepitac. Its a very soft, broad silicone tape that wont pull any hair when beeing removed. it doesnt stick too well, but mostly well enough, except for talents with heavy perspiration. on long chest hair it doesnt work.

    sony m10

    i had a m10 and some old dpa4060 lying around and put together a small rig that i can take with me on travels. really surprised how nice that sounds. the m10 delivers about 3volts, enough to power the dpa´s. the preamps sound more than ok for such a little box. and it runs half a day on 2 AA´s. the mics are mounted on a hd25. i replaced the 3.5mm jack mic input on the recorder with a less fragile connector . if you rip out the internal mics, there is enough space to put in small connector ( hirose in this case ). you will need something with 4 pins, as the original input is activated by shorting 2 contacts by the sleeve of the jack. and two short sound snippets, made with this rig streetkitchen chiang mai.mp3 atmo chiang mai.mp3
  11. hi michael, i used diy lifepo4 batteries for the last 2 years exclusively, but with lesser capacities ( 20 ah ), put in small pelicases. weight reduction is stunning and they proofed to be at least as robust as sla's i did the first pack with just 4 plain cells in series, no protection board. i cannot recommend this at all, as the cells will absolutely die , especially when overdischarged. also, the cells voltage will drift over time, reducing the effectively usable capacity. so, some sort of balancing circuit is recommendable. the places selling those cells are usually carrying a variety of different protection circuit boards in their sortiment, also pcb's with integrated balancing circuits, which i use ( eg. http://www.batteryspace.com/index.asp?PageAction=VIEWPROD&ProdID=5175 ). generally, lifepos need a slightly higher end charge voltage than sla's. as chargers i use ctek car chargers with 14.7v end charge voltage, which are primarily laid out for leadacid, but will charge lifepos ok. never tried a designated lifepo charger as there was no need until now. i guess the powermax chargers will be ok, as they are also designed to charge sla's. they might not charge the battery to a full 100% , but they wont damage the cells due to a slightly low end charge voltage. the discharge curve of lifepos is very flat and voltage under load is quite stable. so, a topped off battery will start around 13.4v and then quickly settle around 12.8v , from where it drops towards 12v until nearly empty. the voltage drop in the end is very steep, so if voltage falls under 12v, the battery is basically flat. marco
  12. re LewisOB: i made similar experiences. there are red accessoires made by "action products" that display bnc connectors for timecode, genlock and many others in a more convenient manner on the camera. which is a good thing, the setups are very tidy. did a feature on epic last summer where it was absolutely impossible to get a clean scratch to cam via senn g3. my rf explorer just showed a impressively massive band of rf signal across the whole spectrum, more or less blacking out the screen when getting close to the camera. for a test, we stripped down the camera to the point where the culprit could only be one of these accessoires. dont know exactly where and how this happened, but one of this things killed more or less everything relying on rf around the camera ( redmote included ). a thing to consider if a scratch on camera is important. on all the others shoots without this accessoires the g3 worked as it should greets
  13. enjoy, in case you dont know this already... :-) http://m.youtube.com/watch?v=ekSglGgaGws&desktop_uri=%2Fwatch%3Fv%3DekSglGgaGws
  14. as someone pointed out the teradek bolt.... we got this unit on set as main videolink from camera to a single receiver and from there to all the monitors by cable. as reach varies (5.8g and walls...), the receiver on a cstand is mostly very close to set or directly on set. and yes sir, its got a FAN that produces a high pitched whine. no problem when shooting outside next to a highway, but completely impossible for quiet interior scenes.
  15. hi larry, out of pure interest: how does a bigger/smaller deviation affect the quality of the transmitted audio ? better/worse s/n ? i use both systems, us and eu, and they sound identical, as far as my battered ears can hear :-).. or maybe the difference ist negligible under real world conditions...or just noticeable when improperly modulated ( too low ) ? best marco
