JUGEE battery teardown short version for "norms".

This is the extra short 3 min version of the JUGEE battery teardown.

https://youtu.be/rncOmGKe4Bc

The full size 36 minute one will hopefully be ready for viewing tomorrow, so this one might include spoilers.  In fact, it's all spoilers.

The JUGEE battery teardown was arduous.

I've made two versions of the JUGEE 1.5V rechargeable lithium cell video.  One is 3 minutes long (I'm about to upload it) and the other is 36 minutes long, and involves dremeling the lithium cell case.

Even after that it doesn't answer all the questions, because the resin they used was very hard and took fire to remove, but still didn't reveal the number of the mystery 16 pin control chip.  It may be proprietary.

Technically speaking, it could all be done with a 5 pin cu...

Not my video. Malware for fast chargers.

It appears that some fast chargers can be updated via their cable, and experimental malware has been written that allows a small device to be plugged into a fast charger and modifies its code so that whatever voltage is negotiated is replaced with the full 20V anyway.

Watch the cheap USB rechargeable lights emit smoke at the end.

Hacking a stinky pink ring.

I filmed this video at a ridiculous time (about 6am) when the previous video subject turned out to be very time consuming due to a construction that is trying to be Clive-proof.  (I will defeat it!)

https://youtu.be/cvXWr8FV51s

It's a badly designed ozone generating ring that I modify at the end of the video to just run on an elevated voltage for better functionality.

Not a video (yet). Really hard encapsulation.

The picture is of a tiny circuit board that fits on the end of a lithium cell in a high profile Jugee rechargeable AA cell that puts out a solid 1.5V for most of the discharge and then 1V to signal that its running low and is about to cut off.

This was supposed to be last nights video, but has been very frustrating due to a very hard glass-like resin that won't dissolve in acetone and seems quite heat resistant too.

I'll keep working on it, but tonight's video will be about an ozo...

DIY beard oil and usage.

A different type of video with this channel.  I know that quite a few of you have beards.

https://youtu.be/BiEFzjd0YZw

If I do release it on this channel I may just release it at the same time as a technical video.

USB powered light string PIR/radar adaptors.

I've had a small batch of these made.  If you want one of the PCBs to play with then let me know and I'll send at least 20 out to randomly chosen Patreons.

I'll probably pre-solder the USB socket on and include the little 3-way socket too.

Zapping a sausage roll.

This may need revisited with an alternative connection method.

https://youtu.be/JBEEgkuowH4

It turns out that sausage rolls are considerably less flexible than hot dogs.

OMG! Unflattering thumbnail.

Something's glitching.   Youtube doesn't like my compression destroying mega Gallium panel.

Here it is though, and it takes around three hours to build, mainly because you need to solder one lead of each LED first and then reflow it while lining it up with gentle finger pressure.  A larger PCB assembly frame would have been a good option here.

Resistors. 70 minutes.

Starting with preformed resistors, time to insert and solder 70 minutes.

Now for the LEDs.

Uh-oh. The prototypes have arrived.

Pretty fast shipping even by standard mail, and no duty - which was nice.

Now I just have to muster the courage to start making one.

Link to the live stream.

If you didn't follow the direct video link to youtube, here it is:-

Tonight's live stream link. (unlisted)

That's the stream set up.  It turned out that the reason I couldn't set it up before was due to my inability to differentiate between 12 and 24hr time.  So arranging it for 9am this morning was not possible due to YouTube not implementing time travel yet.

RF neon tester and electronics jammer.

A look inside a device that is designed for the neon sign industry.

The unit also has the unofficial function of interfering with some electronic systems.

Patreon only live stream?

I was thinking about doing a Patreon-only live stream tonight.

What do you guys think of that idea?

I've tried prearranging a stream, but have discovered a blip where once you have arranged one (Saturday's normal stream) it won't let me add an earlier one.

If we do go ahead with this I may have to set the date in the future, but it will go ahead tonight instead.  (Hopefully not causing another blip in the process.)

Saturdays live stream.

I've set up the live stream for this Saturday.   Probably a nice peaceful one with just me.

The MBC (Manx Beard Club) gate crashed it last week.

Exploring and hacking some mains RGB strip.

This stuff is "minimalist".  It's basically 120/240V RGB LED tape in the style of neon.

It uses a simply remote control unit to allow colour mixing and fading by phase angle control.

https://youtu.be/7fsa7WH1ajU

You don't need the controller to make it light in fixed colours, but the cable that connects to the strip is a bit odd.

Nice machining - crap electronics.

If you've noticed a slight lull in videos recently it's because I was trying to do my annual tax stuff.  It's strange how I can write assembly code for microcontrollers, but when it comes to working out how I spent every single penny over the last year it leaves my head spinning.

But it's done and I can get back to doing productive stuff.  Mainly involving taking things to bits and designing inappropriate PCBs and 3D printed objects that involve fire.

Here's a light that...

Tonight's stream link.

I should really link to these sooner.  Grab a drink and snacks for tonight's stream.

Feel free to suggest topics here.

I may have made Ralfy's new remote too big.

I'm not sure if my brother Ralfy realised what I meant when I said I could repair his old remote by putting it in a new box with a big red button.

https://youtu.be/z7gjQ3OUoIg

To be fair, I didn't say it was going to be LESS than 100mm / 4" in diameter.

I made this right after doing a live stream, so my voice may sound a bit hoarse.

Not a video (yet). Splooshmeister MK IV.

I know this will be a minority interest PCB, but having screwed up with an earlier design - I fixed that design, but then decided to redesign it completely to split the LEDs into two sections, each with their own capacitive dropper.

It's super-symmetrical due to the function, and is natively suitable for 120V or 230V supplies.

This PCB replaces circuitry in a common eBay disco light and projects a fixed colour array of LEDs.  (Or possibly slow colour changing clear ones.) &nb...

PCB error on disco shart (not dramatic).

There's an error on the disco shart PCB that will not affect the 120V use, but will bridge half the LEDs for 230V use.  It's not terminal, but a track will need to be cut to get the other half lit in 230V mode.

This is why I shouldn't really put up a PCB file before receiving the prototypes.

I've taken that file down and will put it back up after an extra option-link has been added.

If you've already ordered some then it's fine.  It will just need that track cut fo...

Saturday's stream link.

I'm not sure how many people will be out celebrating independence day, but the stream will be in the same place at the same time.

PCB Gerber files.

A couple of the PCB Gerber files are now available to download from my website at:-

http://www.bigclive.com/freebies.htm

But initially the zipped file for the huge A4 sized version will only be available at this link:-

It might be a good idea to wait until I've tested the d...

Now here's something nice. (With weird circuit.)

I saw this in a local shop and bought it to see if it did actually rotate.

https://youtu.be/_WOcviOnwbI

It does.  And the circuitry to switch the motor from a standard solar LED circuit is a bit weird.

Autonomous drone teardown.

The future is here, and I'm glad they've not got guns yet, but the beard targeting feature works well.

https://youtu.be/WvvBm5gZoy4

I thought this was going to be an easy video, with just a few anonymous highly integrated chips and some capacitors.  But it took a long time to reverse engineer, as it uses discrete transistors and regulators to facilitate use of a standard microcontroller and spatial chip.
...

Drone versus beard. (Drone won.)

Not a video yet, but caught on video.....

Not a video (yet). Was this a good idea? (No.)

It seemed a good idea at the time.  Scale the LED matrix up to A4 size.

In hindsight that means a 13 by 18 array of LEDs (234) with four solder joints per LED including the resistors, and another two for the power connection.

938 solder joints......

I've ordered five.

I've also ordered five of the new version of the Disko Shart PCB with dual voltage options for 120V and 230V.

And some little USB powered LED string drivers that you can plug PIR or doppler mod...

And another demonetised.

I'm not sure which bit of my recent (unreleased) Japanese vaping device teardown and reverse engineering involved showing physical harm or distress.

The full Sharp Plasmacluster video.

It's a complex thing - but beautifully made.

https://youtu.be/re4F-_FGFvI

I wonder if Sharp are going to get ratty about me inferring that it's an ozone generator in disguise.
