gadget tsundoku

I have one of those piles of unread books from the usual combination of purchases, gifts, recommendations and similar. The above illustration is just a few percentage of the problem.

I've another virtual pile of reading matter on my Kindle, where I've ordered things, planned to start them and then stalled.

The Japanese have a slang word for these book heaps. Tsundoku.

There needs to be another word for the other random piles of stuff that get saved for later. Most of ours seems to migrate into the garage, to eventually get triaged into:

• Definitely useful
• No hope
• Possible use if adapted

My recent camera rig project has been mainly assembled from such bric-a-brac.

Although, come to think of it, next week we're getting another skip, in preparation for the re-build of the kitchen. And hopefully the kitchen won't be constructed from old parts stored in the garage.

Completing the camera rig for the Lumix GH1 (DSLR camcorder build - Part 8)

The re-chipped Lumix GH1 camera rig is pretty much complete.

I still need to add a black flexible donut ring (yep - that's how it is spelled). There's another term for it too, but I won't use that in this blog. Come to think of it they are also sometimes called bellows.

The donut/bellows is to block light between the lens and the start of the matte box.

My existing setup will work without it, but adding it will make things more free from flare. I estimate about £14 for that piece, which would just take me to the £100 mark for the entire camera.

Although this camera will already record stereo sound, I'll next be thinking about a better way to record separate sound, still on a budget.

Adding follow focus to the Lumix GH1 (DSLR camcorder build - Part 7)

I'm still figuring out the Lumix GH1 project. I've made a few small adjustments to the position of things on the home-made rig and just added the follow focus rack. This is one of those situations where photographic cameras and the movie camera business diverge, but a fairly simple change could make quite a difference.

Movie camera lenses are (a) expensive (b) manual (c) don't have many of the last 15 years of consumer advances incorporated, such as image stabilisation.

However, a major mechanical difference is that movie lenses have a gear built onto their focus ring. This allows a follow focus to be driven by an external wheel, and is the way that professional cameras (other than Electronic News Gathering) capture focus.

In order to implement this gearing on an SLR lens, there's a need to add a wrap around wheel with the gear teeth on it. In my opinion, it would be simple for manufacturers to build this into the original design of SLR lenses too, but I can understand why they don't.

A set of movie lenses consists of around 6 primes and for a modern set of Cooke would cost something like $60,000, or $10k per lens.

The lens above is a typical modern and brand new example, complete with a movie style bayonet mount. Notice the gears on the focus ring. Similarly, a set of Leica movie lenses will cost even more, perhaps $100,000. They also have the special gear teeth included.

I did check out the Canon set, which is a mere $30,000, although these use the Canon EF fitting instead of the standard movie one. Sure, these are fast lenses at f1.5, but maybe even these are outside of my budget.

That's where the plastic wrap around cogs and a zip tie come in.

My adaptation of a DSLR zoom lens cost about £6.

I know, it doesn't have the maximum aperture of the Canons or the Leicas, but it does fit straight onto my adapted m4/3 camera and work with the focus rack.

I'm nearly ready to try all of this in a few scenes, once I've put the matte box back on the front. The total cost so far is as follows:

So I'm up to spend of £86, so far. It would be good to finish the project for sub £100.

Plata o plomo en Narcos?

I'm watching "Narcos", the new series about drug dealer Pablo Escobar. I'm up to the part where he's moved from cigarette smuggling to trafficking industrial quantities of cocaine from Colombia to Miami.

It uses an American DEA agent to tell the tale with extensive voiceover to develop the story and provide recaps. I didn't mind this at the start, to get the plot up and running, but it gets more intrusive, along with freeze frames when the agent talks even more.

It's as if, because of frequent Spanish dialogue with subtitles, the producers thought that some help was needed to keep up. I wonder if there'll be a Spanish 'International' version of this series with all the subtitles reversed and the freeze frames removed?

Aside from that aspect, it's an interesting story of the initially small-time criminal who, in a few years, became a ruthless billionaire drug lord, operating his "silver or lead" approach (bribe or bullet) with anyone who got in his way.

He quickly had law enforcement, judiciary and media in his pocket, with any dissenters removed by his well-armed gang. The local area where he lived was bribed with street handouts of cash, extensive housing and other benefits, effectively building a wide zone within which he could live and operate with apparent impunity.

As a dramatisation of real events, it's difficult to know how much has been added, although key facts seem close to how it has been reported.

Escobar bought an island in the Bahamas to use as a stopping off point on his air route and upgraded from 'rented' light aircraft to lear jets and helicopters to ship the drugs. He famously had his own Piper aeroplane installed on the ranch-style entrance to his enormous Medellín home. That's the same plane that he used to personally pilot drugs along the smuggling route.

In a "can't make this up" twist, Escobar's old ranch is nowadays a theme park which still features a now safari-camouflaged plane over the entrance as well as a museum to the drug traffickers.

The series plays as drama rather than a documentary, albeit interspersed with actual footage of Escobar and others, typically during scenes from TV shows and news reports.

Where it struggles as a drama series is that there's no-one to feel sympathy towards.

The traffickers are all reprehensible hoodlums. The police and drug enforcers play fast and loose as well as receiving bribes and payoffs in all directions.

The dullard agent who gives the first person descriptions leadenly 'reads the lines' rather than creating any sort of personality. The appearance of his sidekick is immediately more interesting with perhaps only one fifth of the dialogue.

The dramatic gaps reinforce the sense that I'm watching an offbeat docudrama, yet I'm sure I'll see it through to Episode 10.

Adding a budget matte box to the Lumix GH1 (DSLR camcorder build - Part 6)

Clipping the Lumix GH1 into the cage and adding the matte box only took a few minutes.

The no-brand matte box I've used is extremely basic, although I think it will do the job. I seem to remember that it came with many of the other smaller components which I now store in that orange accessory box.

I don't want to get a replacement until I've checked whether everything else works and that could take some time.

Short term, the matte box and the rest of the assembly is starting to look like a proper movie camera, even if the underlying camera is an adapted five year old device. The fun part is that the same setup will also work with my other video capable DSLRs, although it is useful to have one permanently set up for video.

And cosmetically, looking at the picture, I think I'll need to swap out those blue plastic end-stoppers for the rails and start to think about how to add the follow focus.

Caging the Lumix GH1 (DSLR camcorder build - Part 5)

A few more pieces from the accessories box for the camera jigsaw puzzle.

There's a couple of rails and some pieces to build a quick release mechanism for both the camera into a cage and also for the cage onto a tripod. I'll be using the Arca Swiss system for this, which means I get the greatest interchangeability between my various cameras and tripods.

First, I some 15mm rails and a 60mm spacer, which is the standard dimensions. Then I'll add an Arca Swiss style release to the cage, before adding this bracket and rails combination.

The cutouts in the cage mean there is an access point for the quick release's control. Access to battery and similar parts of the camera isn't so important if the camera is easy to remove from the cage.

Add the rails and also a further Arca plate to the underside of the cage and the main assembly is almost completed. I've used a long Arca plate and double mounting points to provide some ability to adjust the balance of the assembled unit depending on what it is carrying.

I'll also add a top handle to the cage, fixed with two rather solid bolts. That gives a very secure frame for the camera and any accessories which are to be mounted with it.

So far (and as predicted) my only expenditure for this project has been on the square frame for the cage component, which I picked up from eBay.

Now I'll look at all theses pieces together, temporarily mounted on a tripod, but without the camera. Of course, I'll want to use this with the Lumix GH1 that I've re-programmed, but I think it will also work with any of my other DSLRs.

The whole thing will look more finished when there is a camera attached and a matte box on the front. Let's see what I can do with the super budget matte box from the spares box.

Dressing the Lumix GH1 to look more Hollywood (DSLR camcorder build - Part 4)

I intend to use the box of bits and pieces I filmed yesterday to dress the Lumix GH1, to make it look more like a piece of video kit. Most of the parts come from a £25 kit that I bought on eBay a few years ago.

So far I've spent £0 new money on the adaptation. I've also found a few old Olympus Zuiko prime lenses, and have an adapter for m4/3 somewhere, so I guess I can count that as zero spend as well. Realistically I'd probably also use lenses from my micro 4/3 system.

Now to what's in the orange box of bits?

At least there's some rails, which form an important part of the adaptation. The rails are part of the forward facing support structure.

One of my design points will be to use metal clips, rather than plastic, which will at least give some reassurance that the whole thing won't collapse. That's where some spend may start to creep in, although I've found a couple of clamps that are already metal.

I'll also need a quick release system so that I can both remove the camera from the support and remove the support from a tripod. I've found one such clamp (below) but I don't think it will work if I also want to add on a metal cage structure.

The cage is a simple metal frame to go around the camera. The idea is to have something load bearing that could take other peripherals such as microphones, and actually in the case of such a small camera to add some heft, which can be useful for stability.

I've had a quick look at some purpose built cages (which I'll have to buy) but have decided to get something generic rather than a cage built for the specific camera form factor. I'd prefer something larger and fairly square so that I could swap out this test camera if the whole thing actually works.

I found the above bracket thing in the box, which could work until I can get a cage, but it looks so wrong to me, with its plastic bracket and lack of adjustments.

In front of the lens there's a couple more things to consider. One is a focus puller. That's the kind of thing that real movie cameras use and is a big dial geared to rotate the camera lens from the front. I also found one of these in the box, but I think it will also need to be updated.

This basic one looks somewhat spartan, and I don't think would add to the credibility of the finished product. Along with a camera cage, they will probably be the 'ker-ching' moments.

The other front of camera add-on is a matte box. That's the big square box with sunshields which screams 'Hollywood'. Okay, the orange box contained this - which maybe screams 'bad comedy routine', but I'm in two minds about how much it can be rescued.

The challenge is that 'real' matte boxes are pricey items, like this example called 'Viv', which weighs in at just over £1,100.

Georgeous, I'm sure, with its bright tangerine control knobs, carbon fibre flags and cassette-based rotating filters, but I'll probably settle for something that I can update with a spray can. At least the one in the orange box has metal French flags.

Now, where's my screwdriver?

test footage from the re-blown firmware of the Lumix GH1 (DSLR camcorder build - Part 3)

Here's a first test of the modified camera.

I wanted to check that the autofocus could be used as well as manual focus. The key part of this test is check that the focus changes will create a suitably blurred depth of field, which is not what you get from many regular camcorders. It seems to be working.

Next I'll try some footage to a better SDHC card, so that I can crank up the speed of the output. I'd like to shift from the 17 Megabit/second peak of the standard GH1 to closer to 50Mb/s.

I have't manually adjusted exposure or ISO yet, but I want to know that I'm getting the right shutter speed for video (The 180 degree rule etc).

Then I'll be looking for some sort of focus puller mechanism to support manual focusing properly and a few bits and pieces so that I can build it into a rail and cage system. And an external microphone, I suppose.

The orange box in the video seems to contain some rudimentary components that might be useful.

I realise that this camera is already a few years old, but it's fascinating to quickly make it into something dedicated and still useful. And, if it works, the body is still updatable and the lenses and other bits will still work.

Changing the Lumix GH1 firmware (DSLR camcorder build - Part 2)

To modify the Lumix GH1 firmware, I've downloaded the Ptool utility.

It's a Windows exe, so I've had to run it in a Parallels session on the iMac (I'd forgotten just how quickly Windows 8 Parallels boots as a session on my iMac).

The basic approach is to take the standard firmware image for the camera and the use Ptool to edit appropriate settings. There's a wide variety available (with handy hints) as well as some pre-defined sets contributed by other people.

I've defined my own set, which at this stage are fairly conservative. The (at your own risk) process steps are:

1. Download Ptool to a PC.
2. Download a copy of the latest Panasonic Firmware to the same PC.
3. Use Ptool to modify the firmware image on the PC.
4. Create a new firmware image, which must then be copied to an SDHC card in the root directory.
5. Put the SDHC card into the Lumix GH1.
6. Start the camera and then press the play button.
7. Follow the prompts to update the firmware.

The update takes about a couple of minutes and then the new version is ready.

My next step is to try the change with some video recording...

refreshing an old Lumix GH1 for FHD video (DSLR camcorder build - Part 1)

I've been using some video equipment recently as part of the Mixtape sessions and it got me thinking about ways to create a dedicated DSLR rig that could go alongside the Canon system that I normally use.

In practice, many DSLRs have video capabilities nowadays, and my routine use of Olympus OM-D EM cameras means that there is always a video capability available.

For this experiment, I want to make the camera dedicated for video, perhaps squeezing some more bit-rate from it than conventional. I guess it's a form of overclocking. The most well-known modifications are to Canon 5D II and III DSLR - mainly adding new menus for things like sound levels and exposure metering.

My preference was to do something with a micro 4/3 system. The cameras don't have lock up mirror to worry about and the type of sensor doesn't have the same heating issues as, say, a Canon.

I've selected an old Lumix GH1 body for the adaptation. The GH1 has plenty of form for being hacked, the most well known being via the work of Vitaliy Kiselev, who developed a firmware utility called Ptool which takes the Lumix firmware image and allows modification of various parameters.

That also explains why I'm using an old camera body for the experiment - this could all go horribly wrong. Actually, there's copies of the Lumix GH1 on eBay for around £100 now, whilst the similar form factor but progressively improved Panasonic Lumix GH2, GH3, and GH4 go up in price as £250, £400 and £900. I'm guessing the GH5 will appear early next year at around £1000.

The latest GH4 can record 4K video, but I'm happy enough to create something that will run with FHD (Full HD which is 1920x1080 pixels). It's still more pixels than many of the non-huge televisions use and won't look too out of place alongside my conventional HD camcorder images. To put it in context, a conventional 25 frame per second PAL DVD is 720 × 576 pixels per frame.

By using a micro 4/3 I can easily try a variety of lenses, including my old manual OM Zuikos. This could be quite entertaining and create a wide kit of parts for almost no outlay.

I'm also interested to create the finished object with more of a film camera appearance rather than looking like a stills camera, so I'll be looking for some cheap Meccano-like parts to be able to dress the finished item. It was amusing filming some of the Mixtape sessions and to get reactions about having a 'proper camera' when using the relatively modest Canon XF system. For this one I'm thinking matte box and camera cage.

But, first things first. I'll need to re-blow the firmware in the camera...

A few Mixtape @ukmixtape observations from #edfringe

Well.

The month of Mixtape in Edinburgh has reached an end and all the various aspects are returning to normal. I decided not to write about the specifics of the show whilst it was running, but I'll probably add a few posts now its all done and dusted.

• Was it a success? Undoubtedly.
• Did it make a profit? No, but we didn't expect it to. 'Break even' would be an exaggeration, but it's not a deep loss.
• Was it enjoyable as an experience? Absolutely
• Did the audience like it? Most people thoroughly enjoyed it
• Was it hard work? Oh yes
• Would we do something like it again? Probably...

There's plenty of learning points though, and like my day job, most of them have to be learned via experience. In my day job we'd always tell anyone new about the, say, top three things that can go wrong, but also point out that at some point in the first year or so the newbie will experience them first hand.

It's one of those immutable laws, that certain things will happen and however much you try to dodge them, they'll catch you in the end. However, the 'once bitten' adage also applies, so after whatever it is has happened, there's a new layer of experience to draw upon.

So one aspect of Mixtape was the daily marketing and advertising. This needed to be a blend of traditional flyering, critics, meet the media, stage appearances, reviews and the modern techniques of social media such as Facebook, Instagram, Twitter and on-line advertising.

Whether traditional or newer methods, there's still a learning curve. Unlike in mainstream theatre venues, there's no chance that the show will have a regular or previously cultivated audience. It's a new gig every night and with a fresh group of new generally show-savvy audience, who have somehow picked this show from 3,300 others. Being a 10.20PM start show in a venue serving drinks until 5.00AM every morning, there's some *ahem* demographics to consider as well.

Mixtape also had a large venue. One of the larger Underbelly sites and we couldn't help notice that many other shows we visited were in much smaller locations (except for, say, Camille O'Sullivan - where we had numbered seats or that show about Jimmy Savile which was a West End transfer and had a large venue).

Frequently we noticed that other peoples' venues were 30 or 40 seaters, which Mixtape would have easily sold out almost every night. But with a bigger venue there's more vagaries to contend with. Mixtape did manage sell-out, but actually a 2/3 full venue was somewhat more comfortable.

There was also a great choice of shows even in the Underbelly Cowgate. Just in the 21.00-23.00 slot there were 16 shows to choose from, as can be seen on partial billboard behind some of the cast.

We used a fairly wide range of channels to get the audience. It included:

• The preview show - This was run a week or more before the Fringe and sold out in its own right. This also generated some good preview press.
• A small kick-starter style fundraiser. - A good idea although the rules of the particular site created a few problems and a different approach would be used if this was considered again.
• The programmes for the show. - Kind of mandatory, we advertised in the main Edinburgh Fringe Programme (Page 141), the Sunday Times special one covering the Big Four venues and the Underbelly's own booklet.
• The advert boards at the venue - Various sizes and sprinkled around. Of course, everyone else does this too, so there's still a challenge to be noticed.
• The flyers - We produced them and handed them out around Edinburgh. These took some work to produce but seem to be well-received. Its debatable whether giving them to everyone we see really worked and most of the time the hand-out is more selective.
• The wristbands and tote bags - These were used as part of the Press pack and as small handouts to potential audience in Edinburgh. They raised awareness and created a buzz with people tweeting them as selfies and similar.
• The use of reviewers - This was both professional and personal. A tough call when there's 3,300 shows with many well-known people to view as well as many shows funded by theatres or other groups with better access to P.R. Realistically, there's plenty of shows with 'known' writers and produced by 'known' groups which get first dibs.
• The use of twitter - Twitter was used to further promote the show. This has included cast and the production team producing a range of messages throughout the day to raise awareness. It relies on people using #edfringe and other similar hashtag lists as part of their Edinburgh experience, but suffers from the incredibly fast turnover of tweets meaning anything about the show is only 'on top' for a few seconds.
• The used of Facebook and Instagram - Similar to above, except there's a greater requirement for people to seek out the show information in the first place.
• Online advertising - We found some less expensive sites where we could insert some advert blocks on rotation.
• Radio interviews - A few radio spots, both before the Fringe started and then a couple of top-up slots during the Fringe. There was some telly as well, but we don't think any of it got screened.

The Underbelly/Fringe Office provided useful realtime booking statistics.We found that many of the bookings for a show would arrive on the same day as the show itself. An article about The Pleasance made a similar observation for their whole venue.

We always had some bookings in advance, and with the benefit of hindsight we can see that the volume of bookings created a fairly steady rolling average as the days moved along. We could predict our 'average number per day' and throughout the run watched it progress upwards towards a respectable level.

There's plenty more to say, but I think this post already runs on long enough. Expect more ;-)

in the thick of a deep media review

A spin-off from the Edinburgh Fringe this year has been the side events taking place. No, that's the wrong way around isn't it? The Fringe is supposed to be the side event for the main Festival.

Anyway.

Yesterday evening it was the MacTaggart lecture at the EICC, which is part of the Edinburgh Television Festival. Armando Iannucci gave the talk, which is a plea about the need to defend the UK television industry. I'm with him on this one.

As an example, instead of getting a bunch of Establishment interests to review the Beeb, there needs to be another way. I understand the use of the experts chosen, because they can ensure the *ahem* right paths for their relevant interest. In Iannucci's words:

"I see executives, media owners, industry gurus, all talented people; but not a single person who’s made a classic and enduring television show, not a presenter, a writer, director or creative producer, no Moffat or Wainwright or Mulville or Mercurio..."

Maybe the production side is better represented? Iannucci again:

"...nor do I see anyone from our world-class post-production industry or from design or drama, no-one from the enormous world-beating service of day-to-day production, to give their views, to offload their expertise on the difficulties and the joys and the challenges of making world standard public service broadcasting."

Come to think of it, there's no regular viewers represented either. I notice Whittingdale has asked to see Iannucci this morning. We have to hope this is not some kind of reflex tokenism.

And it's bonkers to say that the Beeb shouldn't do web or multi-channel multi-platform. The whole premise of media is now skewed exactly to these varied demands.

Britain has major soft power in the world, with global influence driven through its culture, media and education. The Beeb and UK Television is a significant part of this non-weapons-system.

That doesn't stop the creeping ambition of the imperial elite who drive artificial outrage towards the BBC. This political agenda spin is towards capitalising yet more of Britain away to offshore interests. Cameron won't admit that there's people whispering in his ear, but I still remember that Jeremy Hunt situation around the BskyB bid in 2012. Enough said?

And I can't help noticing, that for every person wanting to defend the UK media industry, there seems to be several saying abolish the licence fee and so on. There's wider repercussions than the 45p per day cost of BBC telly, radio and internet throughout the land.

Here's a copy of Armando Iannucci's well articulated speech.
