Real neon demo case for sign companies

I recorded this while travelling and forgot how horrible the audio is in this recording device. I'll bring the Pixel with me next time.

This is a neon colour display case to help customers c...

Solar powered rotator

I'm in Glasgow at the moment, getting lots of novel things to take apart. I'll try and make some videos here, but they never look or sound as good as the ones made at the usual bench.

This i...

I'm going to release the power block video early

Given how stupidly dangerous the multi-way power strip/splitter/block is, I'm going to release that video early for safety reasons.

A subsequent flame test on all the plastic components showe...

Amazingly dangerous socket strip

You could literally use this popular socket strip as the subject for an entire safety course.

It's almost like they deliberately tried to break every regulation possible.

I've listed ev...

Phone shaker....

I'm perplexed at why they needed to even make this thing. It basically rocks your phone back and forth to emulate walking. Are there jobs where they monitor peoples phones for movement in case th...

Very clever plumbing component

Another refreshing break from electronics to look at something much wetter.

This is a very clever universal float valve with lots of neat features.

Electric shower control PCB fix

The complete lack of an anonymous microcontroller made this quite a fun reverse engineer with no secrets. There were two special function components with vague markings, but the design of the circ...

The hunt for an elusive flame LED

At some point the new style of candle LEDs will appear on AliExpress, but at the moment it's just the harsh flicker ones.

The new subtle style is much more relaxing than the older juddery typ...

With slight screw up

I like to leave my mistakes in.... Let's just say that the coil was not dissipating 35W.

Very simple mechanism in this unit. Just two buttons to push a relay closed and force it open agai...

Have a brain-melter

Having seen these little three pin power supply control chips in various products, I decided to take a look at some datasheets and see if I could work out the magic.

Mini flashlight with better circuitry/software

This unit has jammed a lot of circuitry into a small case. It has one oddity - the LED current limiting resistors for the small LEDs are on the emitters of the transistors, suggesting perhaps a cr...

Something non electronic

Having had a very annoying experience trying to clean paint from a hard to reach stub of pipe, I looked online for techniques or devices that could make it easier.

I found these devices being...

Chunky 3-phase industrial noise filter

Something different that I stumbled across on eBay. It's a bare module designed for electrical noise filtering in equipment with things like variable frequency drives.

It has some quite inte...

Solar pendant light

Quite a nice looking light with potential for being hacked to suit your own requirements.

This video is so fresh that the lithium cell hasn't completed its capacity test yet. It's currently ...

Vintage British Pifco vibratory massager

You may notice that the thumbnail was taken a while ago.

This is a classic British vibratory massage device from around 1950. It is very simple in construction.

As expected of a unit f...

Cheap hackable USB-C flashlight

I've been burning the midnight oil doing cell tests on this unit. It would definitely be a prime candidate for adding a 550mAh cell from a disposable vape salvaged off the street.

They've cu...

Chinese electronic lego timer module

I thought this was going to be an easy video to make, but it wasn't.

It took a LONG time to work out all the modes this unit has, test them and then basically write the entire English manual ...

Deep dive into circuit breakers

A proper deep dive into the trip mechanisms in circuit breakers, and the way the two overcurrent sensing mechanisms work (thermal and magnetic).

It's the first time I've managed to find out h...

Testing a new recording device

This particular recording device has the unexpected feature of zooming much wider than it started off, resulting in a sudden reveal of the clutter around my filming area.

High temperature pink hot thing

This must have other specialist uses where you need something melted in a little pouring ladle. It's intended purpose is heating sealing wax, which is poured onto documents and then stamped with a...

Weekend stream link

Since it's the easter holidays, this stream will be reinforced with cheap fizzy wine. As such, I can't be held fully liable for outrageous statements.

Useful, but frustrating USB remote doorbell

This is a very capable little unit, but is hobbled by the use of long musical sections in place of simple short chimes.

But it has many uses, including pairing with a matching wireless PIR se...

Contactless hand detecting switch

The circuitry in this was surprisingly well designed. It has anti-tracking slots, a fuse and a decent power supply.

This was another AliExpress buy. The listing is linked in the video descr...

Common style of remote control button

These are very common on online selling platforms. They are single code RF buttons that can be used to control lights and other loads. The transmitter chip is extremely standard, so most receiver...

Lidl's amazing value wire ferrule kit

This full kit effectively costs a fraction of what the big electrical distributors sell the basic crimping tool for. It has a very good range and generous quantity of bootlace ferrules for binding...

Exploring an LED bulb that went pop

In hindsight I would have tested the capacitor differently. (Rectifier and a tungsten bulb in series to limit the current.)
But the fusible resistor did an admirable job of limiting the fault c...
