670-Volt LED lamp!

https://www.youtube.com/watch?v=XC0YPNJo6mA

This is a new twist.  A long series string of LED filaments being run at high voltage and low current.  I've never seen an LED driver quite like this before. &n...

Biggest LED COB yet.

https://www.youtube.com/watch?v=uIspnsBp3o4

Sorry for the slight dip in output recently, I was over in Glasgow picking up some technical stuff for our entertainment.

This is a huge LED COB with no less than 3...

Solar light mod.

https://www.youtube.com/watch?v=V70QKWMu7dg

Modifying cheap solar lights is quite an enjoyable thing to do.  In this video I swap a single white LED out for two coloured ones.  It gives a very nice effect...

Street light cut-out unit.

https://www.youtube.com/watch?v=BioanX0RJgI

Probably one of the most functionally designed devices about.  As you may notice I really like the cable termination plate and large integrated finger guard for the ...

Neat waterproof housing hack.

https://www.youtube.com/watch?v=S5yv1ymYYKk

This is a clever repurposing of an existing product to make a waterproof cell holder for the common copper wire LED strings.  I completely forgot to mention that I d...

Mirrorball motor.

https://www.youtube.com/watch?v=dvv3ep2nIz0

Although mirrorball rotators are fun in their own right, they're also a useful source of a slow mains voltage geared motor.  Often cheaper and easier to source than ...

Fake Omron time delay relay.

https://www.youtube.com/watch?v=DeMuNXZ5jLc

This one's actually quite nicely made.  It's a 12V version so it runs cooler than the higher voltage versions probably do.

French MRE test.

https://www.youtube.com/watch?v=9m_bD-xlh_M

Juan and Kevin helped me test a French Military ration.  I'd recommend kicking back with a beer or other favourite beverage for this video.

Making a prototype PCB.

https://www.youtube.com/watch?v=CrdheP3Dwyc

This is the bit I missed out of the disco light hack video.  So I made a complete new board with a revision and to do a test with diffused LEDs.

Disco light complete hack.

https://www.youtube.com/watch?v=rv_Nb-EiPSI

This video is about stripping all the original circuitry out of a cheap disco light and replacing it with a new PCB with LED array and power supply combined onto one pane...

Smokin' hot relays.

https://www.youtube.com/watch?v=E8EH2GqzWNU

While a prototype circuit board is etching I'll just pop this video up.

It's about the cloned Omron relays sold on eBay and gives a hint at how much care went into ...

Simplest solar light?

https://www.youtube.com/watch?v=ycFTxCoNAQk

An explanation of the recent shitty solar panel's performance and a sudden random project build.

I've done a project similar to this one before, but not using the s...

Upload issues.

There was supposed to be a video going up tonight, but I'm having ongoing upload issues with a 4G broadband account that seems to have settings issues that the telecoms company can't quite suss out.  Hopefully the fourth attempt will get a result.

Checking out a large COB array.

https://www.youtube.com/watch?v=9F-WUcJlgko

The LED COB modules are really common on eBay now, so I thought I'd get a few to check out.  This one is actually pretty nice.  I'm not sure how long it will la...

Random solder tests.

https://www.youtube.com/watch?v=n5adgI97qxQ

Lead based solder and candy.  The perfect combination.

Glad I didn't switch THIS on.

https://www.youtube.com/watch?v=K3lBJMpPaOU

A while ago John Ward featured a failed RCBO (Residual Current Breaker with Overload protection) which is like a combined overcurrent circuit breaker with additional eart...

Restoring Centaur's true voice.

The electronic revolution happened when I was a kid and suddenly the amusement arcades full of old electromechanical machines started getting new electronic ones with all...

DIY solar powerbank kit.

https://www.youtube.com/watch?v=0b-8ZWy0y5c

Third time lucky.  (I'm having upload issues.)

Despite the grossly exaggerated ratings, this is actually quite an interesting power bank kit.  It's availa...

Inside a REAL Snap Power plate.

https://www.youtube.com/watch?v=JqBZQ23TaZg

Having already taken a fake one to bits, here's a look inside the real thing.   (Plus another random clone.)

American vs European work shorts.

https://www.youtube.com/watch?v=qE7yqh9mk1g

Dickies has a completely different style of workwear associated with it in different parts of the world.

I thought I'd compare a pair of US versus EU work shorts. 2018-04-21 21:49:55 +0000 UTC View Post

Baymax LED night light.

https://www.youtube.com/watch?v=ghK6-lQnYbw

Back to basics with a super simple night light that can be tweaked if desired.

12V lithium pack with no balancing?

https://www.youtube.com/watch?v=E-sqmNRNbUc

Hmm, I'll let you watch the video and then decide for yourself if this is a viable way of doing things.

It's certainly simple...

The capacity test is still un...

Longer video than expected.

https://www.youtube.com/watch?v=JEczJP7UoRU

I'm not sure how I managed to make this video so long.  There was so much to explore in such a small and delightfully crappy device.

It has intriguing and yet ...

Something I've never seen before.

While playing about with a glitter style lamp I randomly dropped in a few of the Poundland acrylic table scatter diamonds (wedding table decoration).  I then discove...

Dead LED headlight lamp autopsy.

https://www.youtube.com/watch?v=CX_uFs5vKc0

Initially I thought this might just have been a COB style LED array with no current limiting, but it's actually really clever inside.  And fan cooled too, which stil...

USB flesh burning pen. (Yeah!)

https://www.youtube.com/watch?v=aPqHs6TpNug

There's nothing quite like the cosmetics industry to dream up new ways to hurt yourself.  This appears to be one of them.

I've just finished checking the capac...

Selfie light.

https://www.youtube.com/watch?v=2W-8_rzJUzI

I use this little light a lot for the extreme PCB closeups.  It provides a very good all-round illumination.

1W versus 3W LED downlight.

https://www.youtube.com/watch?v=NfUwCWZO0Qo

It's not quite as easy as that as you'll see from the video.  But they are quite nice little machined housings as always.

Test of Yihua 502D PSU.

https://www.youtube.com/watch?v=rz-ndgC6BJ4

It's kind of a fail, but also a hint at hackability and an understated power rating.

In hindsight I'm wondering if the coil and shunt resistance of the meter was af...

500V test of British General USB socket.

This is one of those videos that happens unexpectedly and provides good entertainment value when made with a side serving of sparkling white wine.
