DIY Blimp for less than £20
  • After realizing that a good BLIMP is more about the knowledge and theory, rather than the actual construction materials, I'm embarking on a construction of my own blimp for less than £20. This will hold my cheap chinese microphone EM-320E, which is still on its way. My inspiration came from here:

    and here
    . So whatever advice you can give me on how to improve my design, it would be greatly appreciated, and hopefully will help others later on. These are the materials that I'll be using:

    • Bird feeder (£3) - to make the frame. Length 33cm. Diameter 6cm (the cage is metal, but not too robust. I might replace it with a much tougher mesh from one of those metal mesh bins http://www.ebay.com/itm/190683027361)
    • 2 round tea strainers (£3) for the FRONT and BACK end caps
    • 2 plastic jars with diameter 6cm (£2) - I will cut off the caps so as to make both end caps of the blimp to easily screw onto the frame
    • 300mmX200mm of Ultra fine mesh (£4) http://www.ebay.co.uk/itm/Fine-Stainless-Steel-wire-mesh-Insect-Reptile-Vent-Vivarium-/110876648077?_trksid=p3984.m185&_trkparms=algo%3DRIC.CFNPRP%26its%3DI%26itu%3DUA%26otn%3D5%26pmod%3D110876648077%26ps%3D63#ht_500wt_1077 This will be used predominantly at the front of the construction. Fine mesh will go inside the frame. It will be last layer that the wind will travel through, and hopefully by then it will be completely broken. I'M NOT ENTIRELY SURE IF THIS FINE MESH WILL AFFECT THE SOUND TRANSPARENCY. I really need your advice here. PLEASE HELP!
    • Micro fiber cloth OR nylon stockings (£1) - this will go inside the birdfeeder, after the fine mesh
    • 6 Rubber bands (£0) - to hold the mic inside the bird feeder in X pattern
    • 2 fluffy faux-fur lady's ankle warmers (£5) http://www.ebay.co.uk/itm/300698800758 hopefully these are good, thick and tight enough fake fur to block most of the wind. I will just saw the ends of these fluffies together, to make them into "bags". They are 40cm long, so should hold the entire blip pretty nicely. If you can find any better material on eBay please post a link.

    So what do you think? Will it work?

    I'm especially concerned with a small (6cm) diameter of the birdfeeder, but I hope that adding the fine mesh should supplement that like in this video

    Or am I wrong?

  • I have a WindTech Mic-Muff. Not sure if it's as good, but it's a lot cheaper than a Rode or Rycote.

  • I'm in Australia and have a friend who oftens buys photographic stuff. We generally combine orders when buying from B&H and share the freight costs. Small items are no longer cost effective to purchase from overseas from the likes of B&H and Adorama.

  • @kronstadt .. my apologies I searched for the wrong one .. yeah .. and just looked at prices.

    I buy quite a bit from BHP .. and often face the same dilemna when I am after something rather cheap.

    Currently I have 2 items in my cart. The first I added is $28 (a short hihat locking handle) The freight comes to $32.

    It appears that BHP have a intelligent freight system - based on both weight and volume.

    I have added a cheap Hitech (cokin 85mm sized) low contrast filter for $27. The freight remains at $32.

    I am pretty sure I can add several more items before the freight goes up.

    I have seen in other forums that Adorama can be contacted by email where shipping is an issue and will investigate and/or send via economy UPS, rather than premium.

    Those approaches are all I can suggest. Other than perhaps getting somebody local to you to order it in .. but the best price I found for a UK retail shop is 39 GBP

  • @kavadni all 3 links are "deadcats" that fit over the microphones. They are not the Rode Dead Wombat that fits over the Rode Blimp. I'm building a blimp, so need a fluffy that would fit over it, not inside it ;)

  • Noted .. shall do as pm in future

  • @kavadni

    Please do not turn topic in ebay links collection.

  • @kavadni There's no Rode Dead Wombat that I can get in the UK for £25. They start at £39+shipping, comes to £43-£46. I spoke to B&H. $49.95+$43 (for shipping) .. $93... hmm.

  • I'm redesigning my Blimp to be bigger, with more "dead air space"... 125mm in diameter and 490mm long (exactly like Rode Blimp).

    @kavadni , Can you please tell us where exactly can we purchase a Rode Dead Wombat for £25. At that price-point, I won't mind dressing my DIY blimp with a Rode Dead Wombat. Please provide a link.

    @Roberto thanks, you forgot to mention "and a cup of tea" ;)

  • For chrissakes, the guy's probably got quality time away in his shed. His kids admire and emulate him, his long-suffering wife's back indoors happy with her holiday budget untouched and her new leg-warmers, and hubby's having heaps of science-fun while he hones his skills & gets the satisfaction of finishing a project he can use later.

  • @kronstadt

    that he/she will make for me a custom cover with 7-8cm diameter and 40cm length for £25

    same price as Rode Dead Wombat furry cover

    I admire your desire to make forself, I think this is project you might find not worth while.

    I will go out on a limb and say you will get a better a result with a foam pop cover designed for the microphone and a furry cover made to fit that from a fabric designed for the purpose .. than you will from a birdcage with a non purposed fabric

  • @kronstadt

    As you can see, this is smaller than what you need for your shotgun. I have used this with smaller directional mics (off my Betacam) or with cardoids, over the plastic cage so as to completely envelop the mic.

    Note the silky lining. I do think it matters.

  • This project will take a while to complete, because the parts I've ordered will take time to arrive (we don't have stores like Home Depot here (it's a small town in the middle of nowhere), so I have to order overpriced eBay items for my DIY projects). And I will post updates when I complete it. Hopefully it will work.

    If not, the most I can afford (well, I can't even afford those) is these cheap Indian blimps http://www.ebay.co.uk/itm/140596801213#ht_4978wt_1172 Has anyone used them? Do they work okey?

    @Vitaliy_Kiselev I'd love to get a Rode Blimp, but simply can't afford it.

    @Roberto , thanks for the support. I think you get the spirit of this project "Of all things, photography is noted for the ingenuity of its practitioners. Film sets are full of gaffer-tape. DOP Jack Cardiff would breathe on a lens to fog it up, etc. It's all lots of fun."

    You said you used "a genuine fluffy dog replacement cover, complete with drawstring" - I have no idea what this is, can you please post a link? or a picture?

    It's not about a £12 mic deserving no more than a £20 blimp. Yes, it is about a guy embarking on an ambitious project to make a film with a budget of no more than £6000, so budgeting and being inventive is an integral part of any filmmaking (even when your budget is $60mln). And I think the spirit of GH13 - the crazy idea that you can take a photo-camera, put lenses on it that were manufactured in 1970s and hack/overclock that camera (kudos to @Vitaliy_Kiselev) to make it produce motion pictures comparable to cinematic releases, fits perfectly with the spirit of filmmaking -- that's what intrigued me to buy my second-hand GH1 in the first place. Like anyone else, I'd love to be filming on 35mm filmstock (or even 16mm stock if I could afford that kind of workflow) or Arri Alexa or Red, but I've got GH13 and that's what I've got to shoot a film with.

    For now, if I can get a sound clean enough to be comparable to Aranowski's "Pi" or Nolan's "Following", I'd be happy.

    But there's another element of innovation in this Blimp project, when one day I took my Zoom H1 and a tea strainer and headed to the beach (I live by the sea, so it's VERY windy), and did a little experiment with the tea-strainer on and off. The difference was huge. I am not aware of any manufactured blimps using double layers of mesh (one for the frame and one additional layer of fine mesh to "break" the wind), and then I found that video on YouTube (see above), and it seems that using fine mesh doesn't compromise the audio transparency. So I decided to go for it. At best it could be a blimp that works better then expensive ones, at worst it could be £20 spent on a lesson.

    As for DIY, I do it (even with primitive tools) to cut corners. And so far I've made a slider for £31.57, a crane for £79.87 and many more tools and accessories that are way more capable and useful on locations than Kessler or Philip-Bloom-signature-overpriced-toy.

    As for using the fake-fur ladies ankle warmers, what if I cut out the "silky" internal cloth and leave just the fur? Will that restore audio transparency of the fake fur? I asked the seller about which one is the thickest fur and they said #9 "Wolf" here http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=130649552475&ssPageName=STRK:MESE:IT#ht_7692wt_1241 Should I go for it?

    Instead of using the fake-fur ladies ankle warmers (which I don't see the reason why any less effective then usual fake fur used in so many DIY blimps), I've negotiated with this manufacturer http://www.ebay.co.uk/sch/camera_nation/m.html that he/she will make for me a custom cover with 7-8cm diameter and 40cm length for £25. For a review of what this manucaturer's cheap but effective windshields are capable of see

    I'll also contact micover.com to see if I can get the cloth only. Thanks @kavadni

    Any more pointers, links, sugestions would be greatly appreciated!

  • @pundit

    a cheap shotgun mic with a $250 blimp and dead cat will likely provide more usable results..

    I agree. Good sound is too important to get wrong. It's also the best thing you can do to improve the look of your video!

  • The biggest issue I've had with wind/handling noise was my Oktava MK-012's which I mostly use with hyper capsules indoors. I trawled through various forums and saw many posts from those with identical problems. The most successful solution appeared to be a Rycote Baby Ball gag and Rycote Invision 6 Shockmount, However that was nearly as much as each mic cost. So I tried a bunch of different DIY things none of which completely solved the problems. Finally I gave in and bought the Baby Ball Gag and Invision Shockmount. The Oktava's are much better now but it took me quite a while and a lighter wallet to fix the problem.

  • @disneytoy The reality is a cheap shotgun mic with a $250 blimp and dead cat will likely provide more usable results than a $2000 mic with a $20 blimp in windy conditions. However if you can produce something as effective as a $250 blimp for $20 then I predict there will be a stampede.

  • @disneytoy

    $19 for a mic, we need a $20 blimp

    Well, sort of. Not that I don't see where you're coming from. But it gets complicated. For example, for my own $39 budget I might be so tempted by some $37 mic that I might only leave myself enough for a $2 mouse-mat that I'll wrap around the windward side of the mic (as I've done countless times). Or decide to shoot on a different side of a building..

    My point is rather that, when we understand the principles involved and our budget, we can make very pragmatic decisions. A grasp of the principles of wind protection is indeed something a keen mind can apply well.

    Conversely, manufacturers have constraints (like appearance, freight costs, etc) which limit their ability to make their stuff work properly. Some products are extremely good value, especially these days; others (like miserable attempts to produce something more expensive to do the job of a $1 sock-full of rice for tabletop camera positioning) are no more than snake-oil.

    Of all things, photography is noted for the ingenuity of its practitioners. Film sets are full of gaffer-tape. DOP Jack Cardiff would breathe on a lens to fog it up, etc. It's all lots of fun.

    So look into it, build your blimp - if possible build one in some way better than anyone else has. Then tell us about it.

  • Strangways, i find that true on something like a Rode Video Pro which i also have, the entire mic must be covered, but never had that issue with the Sennheiser shotgun in extreme wind. Probably because the shotgun in those circumstances is 2" from the speakers mouth like a hand mic and gain is way down. I take your point though.

  • My point is, for those of us not serious sound people. Who are investing $19 for a mic, we need a $20 blimp. If we wanted to spend $250 for sound, than we'd be better off spending $200 on a good mic and $50 on the fixings.

  • If you are chasing acoustic transparent cloth .. contact http://www.micover.com/ I emailed and was able to purchase a piece of cloth .. I made (flat - held on to camera body with elastic) wind covers for the surround sound mics on some camcorders.

  • +1 Rode Blimp .. love it .. the NT2 lives in it .. it never comes out.

  • Makes no sense spending $250 for a blimp for an $19 mic.

    First, the only $20 shotgun mike that I see is very cheap chinese HTDZ.
    Second, it is perfectly ok to spend $200 even for $5 second hand mike, as you spending it not according to mike price, but to get better, usable sound.
    As for Rycote, this kit cost the same as blimp.
