Retro and crappy with terrible charge control
Here's a reverse engineering video to balance the unbagging videos.This light is a very old style with utter disregard for proper lithium cell charging.https://youtu.be/HvX4zRKSvrk
An unbagging video
Another bag of goodies to explore. But I'll also release a video about a horrible keychain flashlight for those who don't like the unbagging videos.https://youtu.be/gjPZHcIa-Yk
YouTube live stream flipped image issue
After the recent quiet live stream where the image was flipped, I tried to find out how to correct that. There's no option for the selfie camera mirror function in the configuration menu for the YouTube app when setting up a live stream, and various fixes like changing the mirror setting in def...
Weekend stream
There will be the usual weekend live stream on Twitch. (9pm Saturday UK time)https://www.twitch.tv/bigclivedotcomBest viewed on Twitch, and you may need to refresh the page to start the stream.
Yeah, yet another video.....
Sorry. I've been making far too many videos recently.This one is about the cheap crappy insect zappers being hyped in adverts as being a breakthrough. They have an interesting bit of circuitry for creating around 400V from 5V though. It's actually viable to buy them just for the PCB.https...
Switchable voltage USB-C module
This module communicates with modern USB PD (Power Delivery) power supplies and sends a request for the voltage chosen on the switches.Whether you actually get that voltage depends on the power supply.The voltage options are 5V, 9V, 12V, 15V, and 20V.The main advantage of this module is that the cur...
Perplexing "bed mite eliminator" plug
I was expecting this unit to be doing the usual ultrasonic sweep thing, but in reality, although all the circuitry is there it wasn't doing anything. Maybe it's not continuous or maybe somebody screwed up at the factory. Hard to say.Not that a piezo disk glued to the case like the sounder ...
Tesla miracle heater PTC heater overheat test
A simple test of how the PTC heater block behaves in a total failure situation. In reality, this situation would require a processor crash or triac failure to achieve. If everything was otherwise intact the internal thermistor should sense the build up of heat as "room temperature" and shu...
Inside the Tesla miracle heater
You've probably seen the scam adverts for these heaters on YouTube, Facebook, TikTok and other similar platforms.The circuitry in this one is actually quite acceptable. But it does lack a final thermal fuse in case of catastrophic failure.https://youtu.be/QiDUKYc0B2Y
Debagging joy with hats and router resetters
Another sack of technical tat from AliExpress. These videos are at least as popular as the full-on reverse engineering videos, but catch my genuine joy of decanting a big bag of "stuff" onto my bench.I did enable the affiliate link feature on AliExpress. It doesn't increase the cost of...
Frustrating POE injector plug
This is another of those products where they could have made a great device, but decided to skimp and do silly things like not supervising the winding of the transformers properly.https://youtu.be/qWDD1CJl1f8
Weekend live stream
Usual time and usual place depending on whether your clocks have moved back yet.Best viewed on Twitch, and you may need to refresh the page to start the stream.https://www.twitch.tv/bigclivedotcom
Nice design - shame it's fake
I do wonder if this was ever intended to be a real product that just went wayward. It's feasible that it was originally intended for use with near-UVA LEDs, but then they realised that using bright pink ones made it look really powerful and ultraviolety.So if you want a convenient timed light w...
Patreon stream link
The quiet Patreon stream will be starting about 1 hour from me posting this.Here's a direct link, as the best place to view the stream is on YouTube.https://youtu.be/0N5yuKgmnGc
Greedy influencer status achieved
You may remember that I asked whether you thought I should try the AliExpress affiliate link thing.I'm now trying it on the video I released recently. If anything it actually makes it easier for me to add the product links to the description, and it doesn't affect the price of the item.I...
Quiet Patreon live stream
It's a while since we've had a quiet Patreon live stream.Let me know if there are specific topics you'd like discussed.
Another unbagging video
The third in a triple video blast. I definitely make far too much content.https://youtu.be/_CWQAG81CRY
Quadruple nightlights and a retro unit
So many things and so little time, so here's the second video in a triple video blast.https://youtu.be/T901DZw1JqA
Unbagging joy with loud sparks!
An extra loud unbagging as part of a triple video blast.https://youtu.be/HgS8usrC31A
Weekend live stream (clock change)
The clocks went back an hour last week in the UK, so the stream will start an hour later for those of you who haven't changed clocks yet.Best viewed on Twitch, and you may need to refresh the page to get the stream to start.https://www.twitch.tv/bigclivedotcom
Another relaxing bag of stuff - mainly bulbs
I'll try not to do too many of these unbagging videos, but this might actually be representative of the amount of glorious trash that I buy.Here's a lamp/bulb edition where I added a selection of lamps and other random things.https://youtu.be/oh9WzD8T5Vo
W1209 temperature control module
It's a while since I've explored one of these modules, and this one has stripped the component count down to the absolute minimum.I reckon it must be scanning the display and then pausing briefly to measure the temperature while all the LEDs are off and the supply is stable.https://youtu.be/...
Inside a screw-in rechargeable LED bulb
When I ordered this I thought the bulb was going to charge when screwed into a light fitting, but in reality the screw base is just so the USB chargeable light can be used in existing light fittings.https://youtu.be/cKmS_Twjqis
Another unbagging with weird stuff
The thought of buying a urinal mat had never crossed my mind until AliExpress helpfully suggested one.Then once you've bought one toilet product you get lots more......Then of course we have LED lights and useful stuff.https://youtu.be/a3zxyvdCYjw
Cheap Chinese firecracker unit (with speech!)
No thumbnail, because there seems to be a bit of a glitch between Patreon and YouTube.Here's a look inside a very gaudy electronic firecracker unit with no high voltage zappers. It makes up for that by having four circuits of LEDs and an audio module which plays a firecracker loop eight times,...
The cheaper Chinese firecracker ornament
This is a much cheaper version of the electronic firecracker ornament, but without the zappy high voltage bit.Not sure if the thumbnail is going to work, as I'm getting a "confirm you're not a bot" message in place of the thumbnail.https://youtu.be/9RDX5XZmf7k
Weekend stream
Usual place and usual time.https://www.twitch.tv/bigclivedotcomI'm posting this just under two hours before the stream starts.Best viewed on Twitch, and you may need to refresh the page to start the stream.
Unbagging video
Have another unbagging video while I'm in the process of reverse engineering another hideous (non high voltage) Chinese firecracker ornament.This unbagging predates the video I promptly made about the fake power saver plugs.https://youtu.be/Qc8F3_j4Ots
Tiny downlight with tinier power supply
I mainly bought this to explore the very slim power supply that converts 120/240V to the current regulated supply for the LED.The construction of the actual downlight is pretty good too, with a sensible retention system.There is an element of serviceability in that a new LED could be fitted, althoug...
Inside a very cost optimised "100W" bulb
Aside from the fact that this is actually a 20W LED bulb and has no smoothing, the construction is actually quite interesting. It uses punched aluminium sheet to form a large 3D heatsink.https://youtu.be/2gkBeL_YfZc
