Well engineered German light.

For such a simple light the circuitry inside is quite complex, but well designed and thought out with regards to the component ratings and possibility of failing LEDs.

Slight recording issue...

I cracked the screen of the phone I use to record videos a while ago (with explosives), but recently managed to finish the job.  I've fitted a new screen, but unfortunately it seems to be inducing electrical noise on the video.  So I'll be switching to my emergency backup phone for recordi...

Very long Q&A storytime.

Whoa!  This is a long video.  Time flies when I'm making things and chatting.

Super shady UVC lamp.

This is one of those things that is so completely dodgy that it makes it desirable.  If you want a compact fluorescent lamp (220V) that will expose the whole room it's used in to dangerous levels of UVC light then this might be for you.

Another piezo air pump.

Having near enough destroyed the previous pump I decided to get another for experiments with copper chloride etchant regeneration.

Something very different.

When I was a 10 year old kid in primary school I was daydreaming as usual and suddenly realised that the universe was infinite.  It's not a terribly useful thing to know when you're stuck on the planet Earth, but it certainly stretches your mind since it's quite hard to fully comprehend at firs...

Emulating pyro misfiring.

Part of the reason I have a second bench for filming is to allow more explosive incidents.  The main bench has too much flammable stuff in the same room to be safe for deliberate pyrotechnic stunts.

Polish Xmas lights from Michal.

Michal has sent another selection of items from Poland, so here's the first.  A set of simple mains powered LED fairy lights.

Nice light. Shame about the video.

This is a very stylish and functional LED street light.  It's made by a company called Holophane which is a veteran of the lighting industry.

Profanity alert. (preserved eggs)

Yeah, not the nicest thing to eat.  This video does contain the F word several times and also a sudden and unexpected description of a lewd sexual act.

A motorised fly trap!

This is an interesting but very simple design for a fly trap that uses an intriguing rotating comb device to enclose and then usher flies into a central collection area.

Solar panel sealing experiment.

This is a test of whether it's viable to apply a skim of silicone sealant over the front of a solar panel, and how it affects the efficiency.

An even BIGGER LED array (600).

Well this COB array of 600 LEDs is now the biggest I've seen to date.

Needless to say I tested it and shorted out an individual LED to see how it was wired (differe...

Spoof lamp repair video.

Do you guys think I should I just release this right now?

Spoof video alert.

It's a while since I've done a spoof video.  This one should get all the flaggers hyped up and angry.  I can barely wait to read the comments to see who takes it seriously.

Save the planet by repairing the LEDs.

This looks like a solid and flawless repair to me!

In these times of economic crisis we really need to care for the planet by repairing everything including LED lamps.

(Spoof video coming very soon.)

Tiny piezoelectric air pump.

I have to admit that I thought this might be a clone based on an original piezoelectric design, but using a standard magnetic mover.  But it's not.  And the simplicity of the operation is incredible.

Autopsy on a faulty night light.

I like doing autopsies on things that have failed.  It's always interesting to see what failed, what caused the failure, how it can be fixed and improved.

The extra-safe USB crystal lamp.

Yeah, I've been putting few of these up recently, but this is the safest version running from a USB power supply at around 750mA.  I've also put up the file for download so you can use the PCB file viewing software linked to, to print off your own.

Wound sucking machine.

It's machine.  That sucks your wounds.

I guess the purpose of this device is to keep a slight external pressure on a wound to create a slight outward flow of "stuff" and therefore prevent the ingress of bacteria that might cause an infection.

It seems quite wasteful that it's disposable...

Inside a cable stripping machine.

I got this a long time ago to try and save my fingers from excessive abrasion from stripping and twisting thousands of wires.  It's firmly in the category of proper factory equipment and cost quite a lot at the time.  But it was fully justified in the time and finger-wear it saved.

Do you think I gave this a fair test?

Wafer thin USB powerbank.

https://www.youtube.com/watch?v=mGs9dLepJWY

This has to be one of the squirmiest power banks I've opened.  They'd done an "apple" and glued it shut with the battery being thet bit that had the glue on it.

Audio issues?

Is anyone experiencing audio issues on my videos?  I've had a lot of comments saying that they are only getting audio out one speaker or none at all.

I think this may be due to YouTube encoding with surround sound and something is misinterpreting my bassy voice as a bass channel.
