Behind the Edit: Building the Competent Crew Film

 


Behind the Edit: Building the Competent Crew Film

“200GB of Sailing Footage Later… Making the Competent Crew Film”

Filming a sailing course is easy. Turning the footage into something worth watching is much harder.

That is the lesson I am currently learning while building the film from our RYA Competent Crew course in Croatia.

At the time, it all felt simple enough. Point cameras at boats. Film ropes, sails, steering, mooring, beautiful Croatian coastline, slightly confused students, calm instructors, and the occasional moment when everyone suddenly remembers which rope is meant to do what.

Then I came home.

Then I looked at the footage.

Then I realised I had created a 200GB problem.

Not a bad problem. A wonderful problem. But still a problem.

Because somewhere inside all those files is a film. Possibly several films. There is an instructional sailing video hiding in there. There is also a travel documentary, a course review, a comedy of errors, a technical filming experiment, and possibly a public warning about the dangers of wind noise.

The challenge is working out which one it wants to be.


The Joy of Too Much Footage

One of the biggest mistakes in filming is not getting enough coverage.

So naturally, I went completely the other way.

There is footage from our monohull. There is footage from Sailing Fair Isle. There are wide shots, cockpit shots, marina shots, harbour shots, scenic shots, action-camera shots, handheld camera shots, and enough sea, sky and rope footage to confuse a knot instructor.

Some shots are excellent.

Some shots are useful.

Some shots are technically present but emotionally absent.

And some shots are best described as “wind noise with occasional boat.”

The first job is not editing. It is archaeology.

You dig through files looking for the good moments: a clean manoeuvre, a useful explanation, a laugh, a mistake, a shot where the camera is actually pointing at the thing you thought it was pointing at.

The timeline does not begin with creativity. It begins with sorting.


What Worked Brilliantly

Some of the best shots came from the moments when the camera was simply allowed to observe.

Side-to berthing practice worked especially well because there was a clear story. The boat approaches. The crew prepare. The fenders are out. The ropes are ready. Someone counts down the distance. The helm adjusts speed. Everyone looks calm while secretly calculating whether the harbour wall is approaching faster than expected.

That sort of footage edits beautifully because it has tension, purpose and a result.

The scenic footage also worked well. Croatia is very helpful in this respect. If you point a camera in almost any direction, it tends to reward you with blue water, stone buildings, islands, mountains or a boat doing something photogenic.

The footage from Sailing Fair Isle adds another layer. Seeing the same experience from another boat changes the film completely. It stops being just “our course” and becomes part of a wider story about getting into yachting.

That cross-filming may turn out to be one of the most valuable parts of the whole project.


What Did Not Work Quite So Well

Wind noise.

There, I have said it.

Sailing and good audio are natural enemies. The wind does not care about your expensive camera, your carefully planned shot list, or your desire to hear what the instructor is saying.

A lovely explanation about sail trim can quickly become:

“Today we are going to look at — WOOOOOOOOSHHHHHH — and then you pull the — WHUMP — before the boat — FLAP FLAP FLAP.”

Some footage is visually useful but impossible to use as sound. That means either replacing the audio with voice-over, using subtitles, or turning the moment into part of the story.

There is also footage where the camera angle looked brilliant in theory but less brilliant in practice. Boats move. People stand in front of cameras. Ropes swing. Spray appears. The sun moves. A perfect angle at 10am can become a silhouette factory by lunchtime.

This is the reality of filming on water. Nothing stays still except the shot you forgot to record.


The Editing Problem: What Kind of Film Is This?

This is the real question.

Is the Competent Crew film:

  • an instructional film?
  • a travel documentary?
  • a review of the RYA course?
  • a behind-the-scenes production film?
  • a sailing adventure?
  • a comedy about learning something new?

The answer is probably: yes.

But a film cannot be everything at once. If it tries to be everything, it becomes a long, floating hard drive with music.

So the edit needs structure.

The best solution may be to build the main film as a story of the course, then create shorter spin-off videos from the same footage.

The main film can follow the journey:

Arrival. First impressions. Safety briefing. Learning the boat. Steering. Sail handling. Berthing. Navigation. Confidence growing. Reflections at the end.

Then separate shorter videos can cover specific topics:

What is the Competent Crew course like?
What should you film on a sailing course?
What went wrong with the audio?
Monohull versus catamaran filming.
How to prepare camera gear for sailing.

That way the 200GB mountain becomes a useful library rather than an editing swamp.


The Story Is Not Always Where You Expected

When filming, you imagine the big moments will be the most important.

The dramatic sail hoist. The perfect harbour entrance. The beautiful sunset. The instructor explaining something vital.

But in the edit, the story often lives in smaller moments.

Someone learning to steer more confidently.
A nervous approach to a mooring.
A crew member suddenly understanding what needs to happen next.
A laugh after something goes slightly wrong.
The quiet satisfaction of a manoeuvre that actually worked.

Those are the moments that make a training film human.

A sailing course is not just about ropes, sails and safety briefings. It is about confidence. At the beginning, the boat feels complicated. By the end, it feels slightly less like a floating exam paper.

That is the story I want the film to show.


The Technical Lessons

This project has already taught me several production lessons.

First, audio matters more than almost anything else. Viewers will forgive a slightly wobbly shot. They will not forgive ten minutes of wind attacking a microphone.

Second, camera placement needs testing before the important moments happen. A camera angle that seems clever may only record someone’s elbow for half a day.

Third, too much footage is better than too little — but only if it is organised properly. File naming, backups and daily sorting matter enormously.

Fourth, filming from two boats is powerful. It gives scale, context and movement. It makes the sailing look less like a private diary and more like a proper production.

Finally, the edit must serve the story, not the shot list. Some beautiful shots will have to go. Some imperfect shots will stay because they explain the day better.


Why This Film Matters

For Philip M Russell Ltd, this is more than a holiday video.

It brings together many of the things the company does: video production, education, storytelling, problem solving, sound, photography, editing, and practical learning.

It is also a useful reminder that making educational films is not just about recording information. It is about building understanding.

A good film should make the viewer feel they have been on the journey too. They should understand what the course involved, what it felt like, what was difficult, what was enjoyable, and why it might be worth doing.

And ideally, they should not have to listen to too much wind noise.


Final Thought

Somewhere inside those 200GB of footage is the film.

At the moment, it is hidden among clips of sails, ropes, water, harbours, engine noise, wind noise, beautiful Croatian scenery, and people trying to look calm while learning new things on a moving boat.

The job now is to find the story.

And that is where the real editing begins.

Getting the Leisure/Work Life Balance Right

 


Getting the Leisure/Work Life Balance Right

When the Things You Love Start Taking Over

There’s an odd irony in modern life.

We spend years dreaming about retirement, flexible working, having time for hobbies, finally doing the things we enjoy… and then somehow manage to become just as busy as we were before. I don't even want to give up work when I can discover new things like IR and UV Photography.

The truth is that both work and hobbies can become all-consuming.

Work has obvious ways of doing this. Emails arrive at all hours. Projects expand. Clients need things “urgently.” Deadlines move. Technology means the office can now live permanently in your pocket.

But hobbies?

They can be just as demanding.

Ask any sailor preparing a boat for the season.

Or any photographer who only meant to “quickly edit a few images.”

Or anyone who has sat down at a keyboard to compose “just a short musical idea” and emerged three hours later wondering where the evening went.

The problem is not that these things are bad.

Quite the opposite.

The problem is that even enjoyable things can become exhausting when they crowd everything else out.

The Hidden Trap of Loving What You Do

This becomes particularly interesting when work and leisure overlap.

If your job involves creativity, teaching, filming, designing, writing, building things, music, or content creation, the boundary becomes blurry.

Is editing a sailing video work?

Or leisure?

Is writing a blog relaxing?

Or marketing?

Is designing a logo for a new project enjoyable creative time?

Or another task on the to-do list?

Sometimes it’s both.

That’s where balance becomes difficult.

Because when something feels enjoyable, it doesn’t always feel like work — until you realise you haven’t properly switched off for weeks.

Why Balance Actually Matters

There’s a tendency to think being busy means being productive.

Not always.

Constant activity can simply mean constant activity.

The brain needs contrast.

Rest helps creativity.

Time away improves judgement.

Exercise improves thinking.

Sleep solves problems that determination cannot.

And fun — genuine fun — matters enormously.

A balanced life helps with:

  • better focus
  • reduced stress
  • improved creativity
  • stronger relationships
  • better physical health
  • improved mood
  • avoiding burnout

Even highly motivated people need recovery time.

Professional athletes understand this perfectly.

Musicians understand it.

Sailors understand that sometimes the tide says “not today.”

Yet many of us ignore the same rule in our daily lives.

Hobbies Can Become Jobs in Disguise

This is especially true with technology.

Photography used to mean taking pictures.

Now it can mean:

  • sorting memory cards
  • backing up drives
  • editing RAW files
  • colour grading
  • uploading
  • keyword tagging
  • social media posting
  • creating thumbnails
  • writing descriptions

One hobby can suddenly resemble a small production company.

Sailing?

That’s not just sailing.

That’s:

  • maintenance
  • cleaning
  • weather planning
  • transport
  • charging batteries
  • repairing kit
  • camera mounting
  • editing footage afterwards

Music?

Not just playing.

Also:

  • software updates
  • sound design
  • mixing
  • exporting
  • mastering

You get the idea.

Sometimes our “relaxing hobby” quietly acquires admin.

The Importance of Deliberate Switching Off

One of the healthiest skills is knowing when to stop.

Not because the work is finished.

(It rarely is.)

But because you need to stop.

That might mean:

  • leaving the workshop unfinished
  • walking away from the edit
  • postponing the email reply
  • sailing for pleasure rather than filming everything
  • taking photos without intending to publish them
  • playing music with no recording button armed

Doing something purely for enjoyment can be surprisingly restorative.

Not everything needs to become content.

Balance Looks Different for Everyone

Some people recharge by being active.

Others need quiet.

Some need social time.

Others need solitude.

Some thrive on projects.

Others need empty diary space.

The trick is noticing what restores your energy rather than what merely fills time.

A full calendar is not automatically a fulfilling one.

Retirement Doesn’t Automatically Solve It

Many people imagine retirement as endless leisure.

Reality can be different.

Projects expand to fill available time.

Volunteer roles grow.

Hobbies become serious undertakings.

You can become wonderfully busy doing things you genuinely enjoy.

Which is excellent.

Until it becomes exhausting.

Balance still matters.

Perhaps even more.

Final Thought

Life should contain challenge.

But it should also contain laughter.

Some of the best moments happen when there’s no agenda.

No filming schedule.

No deadline.

No optimisation.

Just doing something because it’s enjoyable.

That balance is not laziness.

It’s maintenance.

And perhaps one of the smartest long-term investments we can make.

Am I old enough to retire - Yes 
But I really don't want to.

Work is fun and so is the Leisure.

Designing the Champagne A-Rater Brand

 


Designing the Champagne A-Rater Brand

Before the Boat Is Mine, the Story Has Already Begun

There is something slightly amusing about creating logos, clothing, music, intro graphics and merchandise for a boat that, at the time of writing, is still sitting out of the water waiting for restoration.

But perhaps that is exactly the point.

A sailing boat is never just fibreglass, varnish, sails, and fittings.

A boat—especially something as iconic as a Thames A-Rater—has a personality.

And Champagne certainly deserves one.

“Before Champagne even reaches the water… the story is already being built.”


More Than Just Restoring a Boat

Restoration projects often focus entirely on practical matters:

  • sanding
  • painting
  • repairs
  • fittings
  • rigging
  • budgets
  • sourcing impossible-to-find parts

And yes, there will be plenty of that.

Quite a lot of that.

Possibly rather more than I currently realise.

But the real opportunity with Champagne is bigger.

This isn’t simply a boat restoration.

It’s the beginning of a full sailing series.

A story.

A brand.

A project people can follow from day one.

From “slightly tired classic boat” to “back racing on the Thames.”

That journey deserves its own identity.


Why Build the Brand So Early?

Because storytelling starts long before launch day.

If you wait until the boat is gleaming on the water, you miss half the adventure.

People love the process.

The setbacks.

The redesigns.

The accidental disasters.

The “that looked easier on YouTube” moments.

The late-night design decisions.

The inevitable ordering of the wrong part.

Twice.

By creating the branding now, the audience becomes part of the journey.


The Name Does Half the Work

Let’s be honest.

Champagne is a brilliant name.

It instantly suggests:

  • celebration
  • elegance
  • speed
  • sparkle
  • heritage
  • luxury
  • perhaps occasional instability if handled badly

Rather like sailing.

The challenge is turning that name into a recognisable visual identity.


The Logo Challenge

A sailing logo has to work in lots of places:

  • boat graphics
  • social media icons
  • embroidered polo shirts
  • hoodies
  • mugs
  • stickers
  • YouTube thumbnails
  • video intros
  • sponsor proposals

That means it needs to be:

  • simple
  • recognisable
  • scalable
  • distinctive
  • legible at tiny sizes

Current ideas include:

The Sail Silhouette

A clean A-Rater profile with its dramatic rig.

Elegant and unmistakably Thames sailing.


The Champagne Bottle Motif

Because the name practically demands it.

Potentially playful.

Potentially dreadful if overdone.

This needs restraint.


Vintage Club Crest Style

Something inspired by traditional yacht club insignia.

Classic typography.

Heritage styling.

Gold trim.

Feels very “old money Thames sailing.”


Modern Minimalist

A cleaner modern identity.

Sharp typography.

Simple line art.

More YouTube-friendly.


Realistically?

We may end up testing all four.


Choosing the Colours

This is harder than it sounds.

The wrong colours make everything look amateur.

Initial thoughts:

Deep Navy Blue

Traditional sailing feel.

Trustworthy.

Elegant.

Timeless.


Gold

A nod to luxury and celebration.

Also works well with the Champagne theme.

But easy to overdo.

Too much gold = yacht salesman.


White

Clean, nautical, crisp.

Essential for balance.


Soft Cream / Champagne Tone

Obvious thematic link.

Can look sophisticated.

Or like outdated wallpaper.

Requires careful handling.


The likely palette:

Navy + Gold + White + Champagne accents

Classic without looking fussy.


Clothing Ideas

Because if you are filming a sailing series…

someone eventually says:

“You should do merch.”

And they are probably right.

Possibilities:

  • embroidered polos
  • sailing jackets
  • caps
  • beanies
  • hoodies
  • crew shirts
  • softshell jackets

Potential branding:

CHAMPAGNE CREW

or

PROJECT CHAMPAGNE

or perhaps:

KEEP CALM AND DON’T CAPSIZE CHAMPAGNE

(Needs refinement.)


Intro Graphics for the Video Series

This is where the film-making side becomes exciting.

The opening sequence needs atmosphere.

Imagine:

slow aerial Thames footage…

close-ups of polished wood…

rigging sounds…

gentle water movement…

old photographs fading in…

then the logo appears.

The tone needs to say:

heritage + engineering + adventure + slightly eccentric British sailing

Not:

cheap reality TV.


Music Themes

This is one of the most interesting parts.

Because original music changes everything.

With access to synthesisers, organ, and music production gear, the soundtrack can be custom-built.

Options include:

Cinematic Heritage

Strings.

Piano.

Warm pads.

A timeless feel.


Modern Documentary

Minimalist pulses.

Subtle electronic textures.

Clean and professional.


Nautical Adventure

A broader, more emotional theme.

The “we are setting sail” feeling.


Light Humorous Theme

Because some restoration moments will absolutely deserve this.

Particularly when something falls off.


The likely reality?

A main heroic theme…

plus lighter recurring motifs.

Every good series needs musical identity.


Merchandise Beyond Clothing

The obvious options:

  • mugs
  • stickers
  • posters
  • framed prints
  • notebooks

The less obvious:

  • restoration workshop aprons
  • embroidered tool rolls
  • crew dry bags
  • sailing checklists
  • Patreon supporter exclusives

A-Rater fans are a niche audience.

But niche audiences can be wonderfully enthusiastic.


Social Media Identity

The branding has to work instantly across:

  • YouTube
  • X
  • LinkedIn
  • Facebook
  • Instagram
  • pmrsailing.uk

Different platforms need different treatments.

Tiny icons.

Wide banners.

Vertical story graphics.

Thumbnail templates.

Consistent fonts.

Consistent colours.

Consistent tone.

This is where proper branding saves huge amounts of time later.


The Bigger Idea

This isn’t just about one boat.

It’s about building a recognisable series identity that people want to follow.

Restoration.

Engineering.

Classic sailing.

River racing.

British eccentricity.

Learning.

Storytelling.

That’s what makes it interesting.

Because by launch day, the audience should already feel like they know Champagne.


Final Thoughts

Right now, Champagne may not be racing.

But the story has already started.

And perhaps that is the most exciting part.

The build.

The design.

The anticipation.

The inevitable mistakes.

And eventually…

the first proper sail.

Preferably with nothing expensive falling off.

Why Educational Videos Often Fail (And How to Make Them Better

 


Why Educational Videos Often Fail (And How to Make Them Better)

“Students rarely stop watching because a subject is difficult. They stop watching because the explanation is unclear.”

That may sound slightly harsh… but after producing educational videos for years, I’m convinced it’s true.

Students will happily wrestle with:

  • difficult maths
  • abstract physics
  • complicated chemistry
  • dense biology concepts

If they feel they are making progress.

What they won’t tolerate for long is confusion caused by poor teaching design.

And that’s an important distinction.

A difficult topic is not the problem.

A badly presented topic is.


The Explosion of Educational Video

We live in a remarkable age.

A student struggling with:

  • differentiation
  • moles
  • electric fields
  • attachment theory

Can pull out a phone and instantly access hundreds of videos.

That’s extraordinary.

But here’s the awkward truth.

A lot of those videos are not very good.

Some are excellent.

Some are… painfully difficult to sit through.

And it usually has nothing to do with the subject knowledge of the presenter.

It’s the delivery.


The Most Common Reasons Educational Videos Fail

1. They Take Too Long to Get to the Point

We’ve all seen them.

You click on a video called:

“Understanding Buffers in 10 Minutes”

And after four minutes you’ve learned:

  • the presenter’s life story
  • what coffee they’re drinking
  • that they nearly didn’t make the video

But not buffers.

Students come with a problem to solve.

They need momentum.

A short introduction is fine.

A rambling preamble is fatal.


2. The Audio Is Terrible

Oddly enough, viewers will tolerate mediocre video.

They will not tolerate dreadful sound.

Problems include:

  • echo
  • hiss
  • clipping
  • low volume
  • background noise
  • inconsistent levels

If students are straining to hear…

They stop concentrating on the content.

And once concentration breaks, learning collapses.

Good audio is not optional.

It’s essential.


3. The Writing Is Tiny

This one drives me mad.

A beautifully explained solution… written in handwriting visible only from the International Space Station.

If a student is watching on:

  • a phone
  • a tablet
  • a laptop

Then small writing is effectively invisible.

The result?

Frustration.

If they cannot read the explanation, the explanation might as well not exist.


4. No Clear Structure

A surprising number of educational videos feel improvised.

The presenter starts somewhere… wanders… remembers another point… circles back… then stops.

The student is left wondering:
“What exactly was I meant to learn?”

A good teaching video needs structure:

  • what are we doing?
  • why does it matter?
  • what do you need to know?
  • worked example
  • summary

Without structure, information becomes noise.


5. Too Much Talking, Not Enough Showing

This is particularly common in science.

The presenter talks about an experiment.

Instead of showing it.

Or describes:

  • motion
  • waves
  • refraction
  • electrolysis

Without visual evidence.

But science is visual.

Students need to see what’s happening.

Talking alone is often not enough.


How I Approach Educational Video Differently

Over time, I’ve built my own approach around one simple principle:

If a student can clearly see and hear the explanation, understanding improves dramatically.

That sounds obvious.

But surprisingly few videos are designed around that idea.


Multi-Camera Teaching Changes Everything

Instead of one static shot, I often use multiple camera angles.

That allows:

  • close-ups of experiments
  • overhead views of written work
  • face-to-camera explanation
  • data displays
  • apparatus detail

Students don’t have to imagine what is happening.

They can see it.

Clearly.

That transforms understanding.


Real Experiments Beat Talking About Experiments

This matters particularly in science teaching.

There’s a huge difference between:

“Let me describe electrolysis…”

and

“Let me show you electrolysis happening now.”

When students see:

  • bubbles forming
  • colour changes
  • sensors responding
  • graphs building live

The concept becomes real.

Not theoretical.

That’s why having both a studio and a working lab matters.


Clear Audio Is a Teaching Tool

I use proper microphones for a reason.

Not because it sounds fancy.

Because clear sound reduces effort.

Students should be concentrating on:
the explanation

Not decoding muffled speech.

Even simple improvements make a huge difference:

  • close microphones
  • noise reduction
  • level balancing
  • removing echo

Good sound makes teaching feel effortless.

Bad sound makes learning exhausting.


Step-by-Step Pacing Matters

One of the biggest mistakes in educational videos is assuming students think as fast as the presenter.

They don’t.

Good teaching pacing means:

  • one idea at a time
  • pause between steps
  • explain why, not just what
  • recap key points

This is especially important in:

  • maths
  • physics calculations
  • chemistry problem solving

Students need time to process.

Fast is not efficient if nobody understands.


Visual Clarity Beats Fancy Graphics

Expensive animations are nice.

But they are not essential.

What matters more:

  • readable writing
  • uncluttered screens
  • sensible zooming
  • visual emphasis

A simple clear diagram beats a flashy confusing one every time.


Why Students Stop Watching

It is rarely because the topic is inherently hard.

Usually it is because:

  • they feel lost
  • they cannot follow
  • they miss a key step
  • the explanation becomes effortful

That’s a design problem.

Not an intelligence problem.


The Real Goal

Educational video should not simply:
deliver information

It should:
build understanding

That means asking:

  • what can the student see?
  • what can they hear?
  • what might confuse them?
  • where might they stop watching?

If you solve those problems…

Retention improves.

Engagement improves.

Learning improves.


The Bigger Lesson

Interestingly, this applies far beyond education.

Whether you’re making:

  • teaching videos
  • sailing films
  • tutorials
  • social media clips

The principles are the same:

Clarity beats complexity.

Communication beats cleverness.

And viewers stay when they understand.


Final Thought

Students rarely stop watching because a subject is difficult.

They stop watching because the explanation is unclear.

And that’s actually encouraging.

Because clarity can be designed.

Building Better Teaching Aids – Why I Keep Redesigning Everything

 


Building Better Teaching Aids – Why I Keep Redesigning Everything

“Good teaching aids don’t just demonstrate science—they make students think.”

That simple idea sits behind an awful lot of what I do.

Over the years, I’ve accumulated a workshop full of:

  • Sensors
  • Cameras
  • Electronics
  • PASCO equipment
  • 3D printers
  • Laser cutters
  • DIY experimental rigs

And yet, despite all the excellent commercial science equipment available today… I still keep redesigning things.

Not because the original equipment is bad.

But because teaching has changed.

Especially online.


The Traditional Problem with Teaching Equipment

Many pieces of science apparatus were designed decades ago with one assumption:
The student is standing right next to it.

That worked reasonably well in a classroom where:

  • Students crowded around a bench
  • The teacher pointed at something small
  • Everyone pretended they could see it properly

The reality?

Usually:

  • The students at the front saw everything
  • The students at the back saw almost nothing

And online learning magnifies that problem dramatically.

A tiny moving needle on a meter? Invisible.
A subtle colour change? Hard to spot.
A delicate oscillation experiment? Lost completely on camera.

So the question becomes:
How do you redesign science demonstrations for the modern world?


Why Commercial Equipment Isn’t Always Enough


Commercial science equipment is often:

  • Extremely accurate
  • Well engineered
  • Robust

But it is not always:

  • Easy to film
  • Easy to visualise
  • Designed for remote learning

Many systems were never intended to be:

  • Seen through a camera lens
  • Viewed on a phone screen
  • Streamed live online

That changes the design priorities completely.


The Rise of the “Visual Experiment”

When teaching online, visibility becomes critical.

Students must be able to:

  • Clearly see what is changing
  • Understand where to look
  • Follow the experiment step-by-step

This means experiments need to become:
Larger
Clearer
More visually obvious

Sometimes that involves:

  • Bigger displays
  • Better lighting
  • Coloured indicators
  • Digital overlays

And sometimes it means redesigning the experiment entirely.


Using PASCO Equipment as the Starting Point

Systems from PASCO Scientific have become incredibly useful because they bridge the gap between:

  • Practical experimentation
  • Real-time data collection
  • Visualisation

Instead of:
“Trust me, the graph should look like this…”

Students can see:

  • Live graphs forming
  • Sensor readings changing instantly
  • Direct relationships between variables

That transforms understanding.

Especially in:

  • Motion experiments
  • Electricity
  • Waves
  • Gas laws
  • Reaction rates

The experiment becomes interactive rather than observational.


But Even Then… I Still Modify Things

Because once you start filming experiments regularly, you notice problems.

For example:

  • A sensor blocks the camera angle
  • Reflections make readings difficult to see
  • Important movements are too small on screen
  • Equipment occupies the wrong space for multi-camera filming

So gradually:
rigs evolve.


DIY Builds – Solving the Problems Commercial Equipment Doesn’t



This is where the workshop becomes important.

Sometimes the solution is surprisingly simple:

  • A different mounting bracket
  • A larger scale model
  • A redesigned support
  • Better positioning for cameras

Other times it becomes a full DIY project.

For example:

  • Building a low-cost linear air track
  • Creating custom mounts for sensors
  • Designing rigs specifically for filming experiments

The goal is not simply:
“Can the experiment work?”

But:

 “Can students understand it instantly?”


Multi-Camera Teaching Changes Everything

One of the biggest changes in modern teaching is the ability to combine:

  • Close-up views
  • Wide shots
  • Data screens
  • Live annotation

All simultaneously.

Instead of students trying to look:

  • At the teacher
  • At the experiment
  • At the graph

They can see all three at once.

That massively reduces cognitive overload.

It also allows:

  • Slow demonstrations
  • Instant replay
  • Highlighting of critical moments

A tiny detail suddenly becomes obvious.


Why Interactivity Matters

Students learn best when they:

  • Predict outcomes
  • Make decisions
  • Observe results

Good teaching aids encourage this.

Bad teaching aids encourage passive watching.

That’s a huge difference.

So I increasingly design experiments where students can say:
“What happens if we change this?”

And then we actually test it live.

This transforms science from:
memorisation

into:
investigation.


Improving Measurement Accuracy

Interestingly, redesigning experiments often improves accuracy too.

Because when you:

  • Stabilise equipment better
  • Reduce friction
  • Improve alignment
  • Use digital sensing

You reduce noise and uncertainty.

Students then see:

  • Cleaner results
  • Clearer trends
  • Better relationships between variables

Which makes interpretation easier.


Teaching Aids Should Support Thinking

This is the key point.

A teaching aid is not there to:
look impressive.

It is there to:
make the student think clearly.

The best demonstrations:

  • simplify complexity
  • focus attention
  • reveal patterns

And that often means:
redesigning the original setup

The Unexpected Benefit – Students See Engineering Too

One thing I particularly enjoy is that students begin to see:

  • problem solving
  • prototyping
  • iterative design

Not just science content.

They realise:
science equipment is designed by people
experiments can be improved
engineering and teaching overlap constantly

That’s a valuable lesson in itself.


And This Is Why I Keep Redesigning Everything

Not because I dislike commercial equipment.

But because:

  • teaching changes
  • technology changes
  • online learning changes expectations

And good teaching evolves alongside it.

Every redesign asks the same question:
“How can I make this clearer?”

Because when students can:

  • see clearly
  • interact directly
  • understand visually

Science stops feeling abstract.

And starts making sense.
