Open Source, Electronics education, manufacturing and Tax policy in the UK

I’m starting to get interested in open source hardware, through building a motion control track to work with DragonFrame’s new ARC moco control. I have been using Arduino Uno and EasyStepper open source boards for this. They are tiny and beautiful in form and concept.

At the same time Michael Gove has started talking about bringing ICT from out under learning to use Microsoft Office into code, which is a Good Thing, although Michael Gove generally has been a Bad Thing. Maybe the LibDems having a positive influence, who knows.
Also at the same time Raspberry Pi is being launched, an excellent initiative making open-source, single board computing available to kids, 30 years after BBC micro launched a revolution in the UK. Back room enthusiasts have had a big part to play in Tech development, Apple started in a garage along with everything else and the start of things doesn’t have to be a spaceship like hothouse.

It’s a sad thing that this can’t all join up with the drive to rebalance the economy away from the deeply unstable and inequitable financial sector towards manufacturing:

The Raspberry Pi charity really really wanted to use UK manufacturing to make it’s credit card sized, pocket money priced computing cards, but has had to take production to the Far East. As with the tax evasion issues raised by UKuncut and the Occupy movement, Inland Revenue has a part to play in this story.

A quote from http://www.raspberrypi.org/archives/509

“I’d like to draw attention to one cost in particular that really created problems for us in Britain. Simply put, if we build the Raspberry Pi in Britain, we have to pay a lot more tax. If a British company imports components, it has to pay tax on those (and most components are not made in the UK). If, however, a completed device is made abroad and imported into the UK – with all of those components soldered onto it – it does not attract any import duty at all. This means that it’s really, really tax inefficient for an electronics company to do its manufacturing in Britain, and it’s one of the reasons that so much of our manufacturing goes overseas. Right now, the way things stand means that a company doing its manufacturing abroad, depriving the UK economy, gets a tax break. It’s an absolutely mad way for the Inland Revenue to be running things, and it’s an issue we’ve taken up with the Department for Business, Innovation and Skills.

So we have had to make the pragmatic decision and look to Taiwan and China for our manufacturing, at least for this first batch. We are still working hard on investigating UK possibilities; at the moment, we’re investigating an option which would mean that all the Model As (whose demand we expect to be much lower than that of the Model Bs) will be built in the UK, and at the moment that’s looking quite do-able, although it’s not as efficient economically as doing it in Asia. I’ll fill you in on how that goes later on.”

JL421 Badonkadonk Land Cruiser/Tank

Hello Buglers,

{This excellent thing was found by listeners to the Bugle podcast.}

[Search for The Bugle, with Andy Zaltzman, John Oliver and F.U Chris, in iTunes(other podcast conglomerators are available).]

and Now…

Introducing the JL421 Badonkadonk Land Cruiser/Tank

The beautiful, the astounding Badonkadonk personal tank. Beautiful and astounding because of it’s shape and size, and also because of the 276 reviews the Good People of Earth have written for it in Amazon.

and have a look at the

Customers Who Viewed This Item Also Viewed section, also amazing.

Many of the also viewed products have their own reviews.

CHECK IT OUT NOW

Such unruly, childish behaviour gives me hope for us all.

iPhone OS 5 bugs

Hello. Anyone having problems with OS 5 upgrade? iCloud I think is my problem. I got duplicated calendar entries first, which can be turned off by selecting just iCloud or just computer, but it is a bit counter intuitive.

Then trying to get my podcasts to be not greyed out has caused some very strange behaviour. Backups are interrupted, restorations must be done, itunes treats my phone as a new device, allsorts. Now trying restore from a backup from a couple of days ago…restore interrupted

okay. back to filling in term and conditions, Apple ID etc.

London Stop Motion Supplies

This is mainly for RCA animation, but anyone can join in.

Please help this become a more comprehensive list by adding good suppliers in the comments section.

Stop Motion Equipment

Some useful kit for Wire Armatures.

Available in the department- hammer, pliers, junior hacksaw, glue gun,

Wire

1mm Aluminium wire

1.5mm Aluminium wire

2 mm Aluminium wire

Opinion is divided as to whether a twisted wire is stronger or weaker than a single strand.

In a quick bench test of solid wire vs. twisted wire, bending at the roughly the same speed and distance, I got these results:

It took 4 strands of 1mm wire to get a 3mm diameter wire, which was surprising.

It took 27 bends to break the solid 3mm wire

39 bends to break the 4 strands of 1mm, although the first of the four strands snapped at 22 bends.

23 bends broke 3 strands of 1mm, and the wire got suddenly much weaker at 10 bends

A second attempt with the same length of wire, got to 21 bends before the first snap and 57 bends before it fully broke, which shows the limits of this experiment.

Andy Joule, Stop motion Lecturer at Farnham, says twisting puts tiny stress cracks in before you start, which may explain the additional softness. Horses for courses.

Both sets of twisted strands had a smoother, buttery bend, much less stiff than the same thickness of solid wire, which is good for animating, unless your model is tending to droop. Twisting together wire and varying the number of strands will also give you different thicknesses from the same stock of wire, which is a practical advantage. Ideally twist wire using a slow drill and a vice, which makes a more even twist than by hand (See Stop Motion, Craft Skills for Animation, Shaw)

Aluminium wire is available online and in some art-shops.

Where available go for ‘soft temper’ aluminium, for the minimum of springiness and maximum staying-where-you-left-it.

Aluminium sheet.

Like thick cooking foil, but smooth to bend, not at all crinkly.

Available in the Department- Ask David Dixon

Or online at MultiFoil.co.uk

Adhesives

 

PVA, an all round useful craft glue.

Hot Melt Glue- An electric glue-gun that melts a solid glue stick that rehardens when cooled. With practice you can be quite tidy with this, but at first it goes everywhere and burns your fingers. Will stick metal only once metal was warmed up. Works very nicely with corrugated cardboard.

Two Part Epoxy Glue- Araldite, and others.

Available in yellow or clear, 5 second to slow cure.

Evostick/Bostick brown rubber glue, remains completely flexible when dry unlike even PVA glue, good for gluing foam, cloth and felt.

Available in hardware shops, stationers & art shops

Rigid materials

Balsa Wood

EPS (Blue) Foam, (Extruded polystyrene) A stiff carvable foam, blue or pink,

used for insulation. The dust is hazardous if breathed in, so wear dust mask and hoover afterwards.

Cavity filler foam. Very sticky expanding foam from a can, that grows to fill a space and can be carved afterwards. Not cheap enough to make large scenery.

Elastic Materials

EVA foam,

dense and rubbery, often comes in brightly coloured sheets

Styrofoam, (Expanded polystyrene)

open cell foam, bendy but not stretchy/rubbery, usually white, sometimes green. Not ‘oasis’ floral foam which is horrible. Mikey Please used this in ‘The Eagleman Stag’

Upholstery foam, often found in skips, inside office chairs. A versatile foam that can be snipped to shape with scissors.

Mouldable materials that go hard

Milliput, a two-part epoxy putty. Mix the two parts together, it stays soft and mouldable for while, becoming fully hard in one hour.

Super Sculpey, a modeling clay that can be baked hard or left soft. Comes in a Caucasian skin tone and before it is baked has the translucent look of waxy skin. Once baked becomes opaque.

Plaster of Paris (see casting)

Moldable materials stay soft

Plasticine- NewPlast is the normal animation plasticine of choice. It doesn’t melt under hot lights, although it does get sweaty and soft with a lot of heat.

Newplast can be pressed into ‘press molds’, American plasticine, like Van Aken, can be melted to liquid for use in pouring moulds.

Unbaked Super Sculpey, (see above)

Others:

Morticians wax is interesting stuff, it is transluscent and can be coloured with small amounts of plasticine, but must be kept fairly cool. Earth wax would need to be kept warm to be pliable but may have possibilities.

Ceramic clay needs to be kept constantly moist and will veer from liquid to cracked mud in a single shot

Cloth Tape, gaffer tape

Newplast

Beads

Paint

Lock-down Feet

M3 or M4 nuts in the feet, bolts coming up from under the table.

Bolts are often modified

Casting Materials

Plaster of Paris: like what is used to fix a broken limb.

A powder mixed with water, becoming like thin cream, then thick cream, then solid.

You can coat a soft plasticine model in wet plaster then remove the plasticine and fill the gap with silicone or expanding foam. Read up about two-part casting as it is a fiddly process and you need to avoid bubbles. Sussanna Shaw is a good place to start.

Use a Rubber bowl to mix and a set of digital scales to weigh out the measures of water to plaster, as you are only using small amounts the exact ratio becomes more important.

Plaster come in a range of types with different properties. Dental Plaster “ULTRACAL-30″ or Basic Alpha Plaster will give a fine, very hard cast, Fine Casting Plaster makes a less dense weaker mould.

Dragon Skin Silicone, a two part silicone with good shore strength

K&S tubing (brass tubing in graded sizes that telescope into each other)

Sandpaper

Drill and Drill bits

Small vice

Wire snips

Pliers

Hacksaw

Screwdriver

Needle files

Scissors

Most of the above can be found most cheaply online, with a little cross-referencing to make sure it is what you hope it to be.

 

The following pages are some places you can get your real hands on what you are buying and give it a squeeze or a bend.

Very cool children’s animation. We had the much more domestic Morph in the UK while the USA had this wild character

Don’t Hug Me I’m Scared

I love this, it’s by THIS IS IT COLLECTIVE

final cut x issues

A worrying time with Final Cut Pro:

A redesign by the guy who made iMovie impossibly cramped and unpleasant to use.

A general sense of direction towards ‘if we were designing from scratch, ditching all the legacy stuff that comes from earlier versions and concepts that come from editing 35mm film’

A move to the Prosumer market.

I have a problem with the idea of the Prosumer. I’ve never met one, and I have a feeling they don’t exist. The Market I recognise is for freelance creative people and microbusiness who can’t justify huge outlay but have the skills and conceptual base to use whatever they can afford to the maximum of it’s capabilities. I think these have traditionally been Apples footsoldiers. The software, and hardware, that suits those people is open and adaptable and plain and efficient.

The idea of dumping the legacy of traditional modes of editing makes sense from a programmers point of view, but for an editor it’s like Esperanto- a logical, designed language that lacks either evolved usage or…zzz.

hope they fix it.
