We covered a source for cheap visualist miscellany last week. It included cheap NTSC CMOS cameras, but unfortunately DealExtreme doesn’t seem to stock much PAL gear.

I had gone looking and placed an order with another site, but didn’t want to recommend it until that order had arrived intact.

That order has arrived intact.

The source for these cameras is DHGate, which is a “marketplace” rather than a direct merchant. DHGate provide a database of products and act as an escrow for payment, it feels a little like eBay. Terms are set by the individual seller, so it’s not a free-shipping wonderland like DealExtreme, but the prices are still finger-tinglingly low. I ordered 16 of these little cameras, which seem to be the PAL version of the NTSC ones at DealExtreme. 16 cameras cost me US$219 including shipping ($13.70 each) and they arrived in about a week. I’ve unpacked and tested them, and they’re all working perfectly.

UK touring visualist Deepvisual (who is currently kicking around the UK with The Orb) has posted a 3-minute overview into his touring rig.

There’s a lot of great tips packed in to 3 minutes of video, so pay attention. I wish someone had told me “take some chocks along to help angle your projectors” before I wasted countless hours over the last year searching around various venues for scraps of wood.

I swear by baluns, which allow me to use readily-replacable CAT5 cable for video runs. Also an inexpensive power inverter is a great addition, to keep your laptop, mp3 player, and phone charged on those long drives between cities. I’d love to hear from other gigging visualists though: What’s your secret touring sauce?

We’ll have some more on the Robotic Camera thing soon, but in the meantime, check out the Pilot View FPV 2400 kit. It’s not quite the gyro-controlled version (below), but apparently they have a pan/tilt coming soon.

As an intellectual exercise, let’s price a similar setup from aforementioned cheapie online store DealExtreme:

USB 2.4GHz Spy Camera Set: $120
iTheatre Virtual Vision Video Glasses: $149

Ok. I don’t think I should be considering this any further. VJing is an expensive enough hobby, remote control flight would be the end of me.

As a visualist I have an incessant appetite for gear. The inaugural Plug N Play Brisbane on Tuesday reminded me that it doesn’t have to be this way, however. While I rocked up with bags and boxes of computers, cables, cameras, controllers and hardware, others arrived with a single laptop, and of course were able to put equally compelling material on the screen. Or, to be perfectly honest - more-compelling material, as I struggled to remember which icons were required to get 3L’s automation chains working.

Debilitating addictions aside; everyone present was interested in my source for cheap security cameras, BNC converters, HDMI cables and other necessary items, so I’m guessing that the rest of the community may also enjoy: DealExtreme (disclosure: Affiliate links used, if you buy stuff I get a cut).

DealExtreme has a huge range of, basically, ephemera: iPod batteries, LED torches, cable converters, chargers… The type of things you’d get for $20 in a local shop, or you could find on eBay for $2 plus $15 shipping. DealExtreme matches those deceptively cheap eBay prices, and then proceeds to not charge shipping, which puts everything into the category entitled “Ridiculously Cheap Stuff”.

The range is large and varied. This coupled with a not particularly intuitive search and categorization of the site has resulted in me wasting many hours paging through, but along the way I’ve bookmarked plenty of things which may be useful to the average VJ:

Apple’s iPhone — and the significantly more affordable, doesn’t-have-to-be-a-phone iPod Touch — are essentially pocket-sized, intelligent multi-touch controllers. Hooking them up to visual software as controllers simply requires some app on the phone to transmit data, and some way of dealing with that data on the computer side. We’ve already seen this a bit on Create Digital Motion, and we’ve been covering some of the specifics of parsing data with Pd (Pure Data), the open-source, tri-platform patching software, on Create Digital Music this week.

Here’s the basic setup:

On Your iPod/iPhone

You have two options of software to use on your iThing. (You’ll need to “jailbreak” your device, as these are not — and may never be, for all I know — approved Apple apps.)

1. mrmr by Eric Redlinger of Brooklyn (top right):  open-source, editable control screens (requires Mac-only software to edit). See our interview with Eric, including some examples with Quartz Composer.

2. akaRemote.app by Masayuki Akamatsu of Japan: not open-source, not editable, but comes with a set of useful control templates, and you can transmit data to the app. See our look at a recent release. Upcoming Mac-only visualist app 3L has its own special akaRemote-based bridge called i3L, which also runs on iPhone/iPod Touch; see our look at i3L with artificial eyes.

On Your Computer

While the iPhone and iPod Touch have Apple logos on them, all of these apps send OpenSoundControl data. That means any OSC-compatible software will work, which is gradually including more visual software, as well as modular apps like Quartz Composer, Max/MSP/Jitter, Pd/GEM, and vvvv. (I love saying that last one … vvvvvvvvvvvvvvvvvvv. Okay, moving on.)

Of all of these, Pd is the one solution that’s free, open source, and runs on any platform. That means it’s also a viable candidate for translating incoming OSC data to more broadly-compatible MIDI. (i3L has you covered, as it uses a MIDI bridge.)

We have not one but two sets of tutorials / example patches for working with Pd on Create Digital Music, using a patch like Cesare’s, pictured above:

Control Music and Visuals with iPhone/iPod, Free Via Pd

So, Is It Worth It?

I usually don’t ask that question, preferring instead to report on what other folks are doing. But it is always worth asking yourself — and it is an entirely personal question. I’m not totally convinced in the case of these devices that I’d want to buy one solely for VJing, but then, what makes this so cool is that it adds on additional functionality to a device. (Too bad Apple is being so uptight about third-party development, but at least there’s an SDK — and plenty of hackers ready to break Apple’s rules.)

My own preference remains squarely with tangible controllers and tactile feedback, especially as some of the advantages of multi-touch are diminished by the iPod/iPhone’s diminutive size. But I absolutely see the argument for using these. What do you think, dear readers?

High speed video is rapidly getting more accessible. In late 2006 a camera which could do 500FPS would set you back US$8800 (or $350/day rental). Now, the newest addition to the high-speed-cameras-for-normal-people - the Casio EX-F1 is shooting at up to 1200FPS, for $1000.

Of course, it’s a still camera as well, and it records 1080i and 720p footage, but I didn’t put “slow motion” up there in the title of this post to talk about boring old 30FPS.

The EX-F1 encodes straight to H264, so none of the shoot-wait-shoot behavior of my Sony tape-based HVR-V1P, and it doesn’t seem to have the same 3/6/12 second real-time limit. Like the Sony, slow-motion causes a loss of frame size: 300FPS gives you a reasonable 512×384 (considerably better than the effective resolution I tested from the HVR-V1P), 600FPS drops you to a youtube-esq 432×192, and 1200FPS gives you 336×96.

As seen in the above video, a little creative framing and editing will let you work with this limitation, but it looks like we still have a while to wait before we can mix full-frame slow motion video in to our projects. 512×384 is definitely useable though, and can give some beautiful results:

As we strive for more immersive, cohesive shows, DMX is a great tool to have in our visualist kit. Whether a full theatre lighting rig or just a couple of dimmers and a strobe in a club, the ability to plug in and take control of an existing rig means that lighting can now work with your projections, not compete with them.

One very exciting piece of gear brought to Perth last year by artificialeyes was the uDMX USB DMX controller. The uDMX is exciting in a different way to gear such as the VJX16-4 or the VMS, rather than being a new and more VJ-friendly take on existing tech, it very common concept - the DMX controller - distilled down to its tiniest, purest form, and then open-sourced for good measure.

The Anyma guys have managed to fit all of the DMX control circuitry inside a regular XLR jack. This makes the uDMX about as compact as it’s possible for a DMX controller to be. As DMX uses regular 3- or 5-pin XLR jacks for cabling, you can literally grab the uDMX, some spare mic cable, an adapter or two, and then get your DMX on straight away! The uDMX-Midi Interface Software (Mac) is extremely simple, monitoring a MIDI input source and converting (scaling from 0-255 to 0-127) either Note-on or CC messages into DMX messages. These are sent through the uDMX on the same DMX channel as the MIDI message controller or note number. It also has the ability to offset messages, which gives a simple method of scanning around DMX channels to find out where lights and other gear are located without following cables or looking at jumpers. Anyma have also released a Max/MSP external (Mac, Linux and Windows), PD external, and a command line utility (Windows, Mac and Linux).

During the high-definition wars, your feelings about new higher-capacity storage discs may have ranged from ambivalence to dread to simple disinterest. (Well, that’s how I felt, anyway.) But with Blu-ray triumphant comes this realization: "hey, brain, we’ve suddenly got increasingly-affordable ways of burning high-capacity media!" Drive upgrades on the PC side cost what DVD burners once did, and if you’re hooked up to a TV, the writer can be your player, too. (There’s already a Lite-On internal drive for around US$350, and I expect these prices will plummet as production ramps up.)

That’s burning, anyway — authoring is obviously essential.
