Another washing machine component.

https://www.youtube.com/watch?v=jSEKMeAv4ps

It's a while since I did one of these things, so here's a teardown of a typical drain pump used in a wide range of machines.

Once again it's optimised for easy manu...

Fixing a duff USB power supply.

https://www.youtube.com/watch?v=CkQ9HN7QNNk

I wonder if this thing had a rough shipping experience, since the case seemed a bit weak and there was possibly a vibration/impact induced issue.

The product gets a...

Gasoline/petrol powered pocket warmer.

https://www.youtube.com/watch?v=WE-b2LjRW5E

This thing is actually quite neat and relatively safe in a cold environment.

Inside a faulty Samsung lithium cell.

https://www.youtube.com/watch?v=gYFuVbZmu5M

This is the first time I've had a lithium pack fail like this, so I just had to go deeper.  They sure do jam a lot of foil, coating and membrane inside a typical 220...

Cheap eBay LED power supply.

https://www.youtube.com/watch?v=Rcuk8wPinkM

This video started off badly with me misplacing the tiny supply completely and taking about an hour to dig through all the stuff in the vicinity before finding I had rand...

Another 4K test of the Irish Sea.

https://www.youtube.com/watch?v=1UcxTrNfWbk

No sound this time because it was so windy I turned the microphone off, so you'll have to make loud seaside noises while watching the video.  Also a bit of a jump at...

4K SJCAM camera test.

https://www.youtube.com/watch?v=av3rrNZjo60

I've been playing with an SJCAM SJ7 Star camera.

What do you think of the video quality?

10400mAh power bank. (yeah right!)

https://www.youtube.com/watch?v=qC--ZT418eI

This is another of the dodgy power banks being sold on eBay that have completely fake ratings.  But that said, the design of this unit is actually quite nice.

2kV test on Poundland's new USB PSU.

https://www.youtube.com/watch?v=aS1pwoVdRh4

I'll warn you in advance that this is a long video involving load, thermal, isolation and flash testing of Poundland's new £2 dual port 2.1A power supply.  (2.1A to...

Quick look inside a flash tester.

https://www.youtube.com/watch?v=AzKCAl-2xJo

This was just a quick (low volume) video I recorded earlier in the year when I received a flash tester from an eBay seller.  It will appear in the next video when I ...

Inside a heated powerbank.

https://www.youtube.com/watch?v=o7IvYsPYiFA

Yes indeed, a heated powerbank does seem like a bad idea.  Especially one rated at pretty much 10W when fully charged.

European candy-fest.

https://www.youtube.com/watch?v=yxtxb7w8zSQ

Thanks to Ian and Attila for sending some sweets from Germany, Slovakia and the Czech republic.  The flavours are diverse and very interesting with some ultra extrem...

Crazy Russian Sparker.

https://www.youtube.com/watch?v=S5uiupJQc9M

As promised, the teardown of a very simple but also very shady device.

I have since fixed it, but I think the windings may be a bit fried due to unreasonable techni...

Little bundle of dubious 240V soviet joy.

This is just a picture...   The video will come later, but this little gas lighter device from the Ukraine is very shady.  It also appears to have a very low duty cycle as demonstrated by the smoke that came out of it when I was taking this picture.  I get the feeling that it may...

Inside the cheapest remote socket on eBay.

https://www.youtube.com/watch?v=RdqzdMUO6QE

Shitty case and a low price, but looks can be deceiving.

This unit lacks a thermal fuse in the vicinity of the relay contacts to detect meltdown, so it shouldn't be...

Repairing a dead UV curing light.

https://www.youtube.com/watch?v=I_LcwHqBm0k

Someone mentioned that they did a rechargeable version of the UV curing/exposing light, so I thought I'd take a look at one.  It arrived dead, so that's even better,...

Fibre optic picture.

https://www.youtube.com/watch?v=SNM6527nE30

Sorry for the gap in videos, I've been in Glasgow for a week.  While I was here I bought a rather neat framed canvas picture with integrated fibre optic lighting, an...

Unexpected video material.

https://www.youtube.com/watch?v=xLhng9BI9Mw

I wasn't planning on making a video about this until I turned on a light switch for lighting that I rarely use and it arced loudly and a lamp failed.

It was the swi...

Vehicle LED thing.

https://www.youtube.com/watch?v=44mj4kNJ_Uk

Just a quick video showing a little positionable LED feature light for vehicle or other use.  These are a cheap source of an LED housing and lens holder, pre-fitted ...

A mechanical interlude.

https://www.youtube.com/watch?v=0mQx5QKJu08

It's not just electrical stuff I like to take apart.  This stopcock was particularly interesting for many reasons.

Smashing and fixing the LED star lamp.

https://www.youtube.com/watch?v=HNaU76L296Q

This is a long and enjoyable video, so grab a drink and kick back.  It involves unreasonable force with lots of broken glass, and a super simple new power supply for...

A nice twist on the LED "neon" effect.

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

I've already featured the mains voltage LED strip that produces a very diffused line of light to emulate neon, but this is a nice twist.

It's a low voltage version ...

Really weird design?

https://www.youtube.com/watch?v=3_3FCAbNyMM

One of these socket testers has great circuitry and one has not.  I'll let you come to your own conclusion about the lesser one.  Note that it may have been the...

Colour temperature selectable bar.

Oops!  I appear to have messed up and made this public instead of unlisted!  But not to worry, I'm about to record an interesting (but quite perplexing) video t...

Let's have a Patreon-only "Ask me anything."

Go on then, ask me anything.  I may even make one of those ambient "building something while I answer questions" videos.

12W enclosed LED module.

https://www.youtube.com/watch?v=rhlM2sPU_Z0

This looks like it's designed to replace the 2D or circular fluorescent lamps in standard bulkhead style light fittings.  It's quite neat inside.

Poundland cinema sign.

https://www.youtube.com/watch?v=5bWAx1H6JYA

I've softened the colour and added diffusion to the setup to try and hide the harsh reality of my work-optimised hands.

Once again Poundland has supplied what appea...

Yuji high CRI LEDs.

https://www.youtube.com/watch?v=9v48gXbolFU

Having wanted to try these LEDs I was secretly delighted when Yuji offered me some.  I've fitted them into the bench lights so we can all benefit from their better c...

Inside the little UV resin curing light.

https://www.youtube.com/watch?v=9ZTyfYLvK14

Having featured it in use recently, it seemed like a good time to take it to bits.
