Thanks, you are correct. The second hand gear wheel has slots in it which pass between the diode and transistor. The LED is pulsed for 30 seconds and when the transistor doesn't respond the pulsing stops. the LED only takes 84 micro amps and the device without motors 160 micro Amps. the LED has a Vf of 1.17V. the transistor's resistance changes from 10k in light to 150 Mega Ohm in dark.

@@leehayes4019 Wow that was quick. Thanks for the comment.

@toyhacker4647 yeah m subscribed because you make great videos!

@@evgenidraganovevgeni7054 glad to have been able to help.

@@nasym909 thanks for the comment. I'm sorry but I don't know. I think the time is built into the chip and can't be changed 😞

​@toyhacker4647 thanks for the reply,how about adding a transistor and a capacitor in place of the button and then everytime the circuit stop the capacitor discharge and turn it back on again?

@@refotografiathanks for the comment, the case has 4 screw's under the rubber feet.

@@Caddy2006 thanks for the comment l just wanted to get it going. I suspect that it is all handled by an IC which would be too difficult to hack.

@@JohnnyMeccano thanks for your comment l would love to know if it is possible.

@@toyhacker4647 the problem is, I can't find anyone with a broken PDU to copy the gear from. I have a dozen but they're all in good running order. Anyway, the word is out. Maybe someone will 3D print it someday.

@@JohnnyMeccano thanks for the comment. I'm not really into 3D printing but I think the teeth would be too small to print.

😊

"god's mammal" and "bible" 🤣🤣😂😂🤣😂🤣🤣🤣😂

Thanks for the comment. Glad it helped. The solar lights don't seem to be as good as they were. I had one with no protection found the cells outer case some distance away but never found the chemicals!

@@toyhacker4647 I prefer NiMH over lithium for small outdoor lights, they've lasted over a decade in some lights, always longer than the legs on the old style leds. Most lithium, even Panasonic, give up after a winter as there's no low temp cut out, never mind discharge protection. The only advantage of lithium cells is that they are higher Wh, free or very cheap & everywhere, even some disposable vape cells last a thousand cycles or so.

It isn't just a sensor but contains battery protection circuits and a timer. If you replace it you would need to add a battery protection circuit to prevent the cell going below 3V and 4V2 when charging.

I have a different kind of circuit from a vape. Can I email it’s pictures to you? It’s bit different than the one you have in this video

@@JunaidShafique Thanks for the offer but I'm a busy at the moment.

It makes t much easier if all the wires are different colours. I've had some horrble troubleshooting when just one colour is used. Thank you for your comment.

ok😊

Thank you for your comment, but what you want is outside my knowledge base. I assume they are special displays made for this purpose.

Thanks for the comment. I've been working on sun and planet gears which have done my head in, but I am almost ready to make a video.

Thank u for videos, sir !!

Glad to hear that.🙂

Sometimes a bit of aluminium foil stuck on the bottom of the rubber button [the black dots shown at 2min 12 sec on video] can replace the worn out pad.

@toyhacker4647 thanks, I'll try that

Good advice. I try to pick up the ones I find in a tissue.

Sorry haven't repled before, you should be able to find a replacement speaker on ebay.

Sorry it's been so long. The videos I post are what I do anyway

Glad it helped.

​@@toyhacker4647 Could you possibly look into the robosapien v2 sometime in the future?

@@electrictnt4482 It's on my todo list but a long way down.

​@@toyhacker4647awesome

No idea but they all disposable vapes may become illegal in the UK soon.

@@toyhacker4647 I was talking about the "Zkittles" name. Sounds like somthing weed dispensaries in parts of the US get sued for.

Thanks for the comment🙂

Lithium-ion batteries

Sorry didn't finish I thing the cells in reusable vapes are Li-ion 18650 cells but Li-ion are used in disposable vapes.

@@toyhacker4647 how do you tell the difference? I have some pe112245 3.7v cells out of breeze disposables that I'd like to play with, but I want to be sure I'm using the right charge profile. Couldn't find any real info on them, they don't seem to be for sale anywhere.

Best way is to use a commercial charger but I don't know of one for these cells.. As the cell is 850mAh called C) the best rate is to charge at 1/10 C i.e. 85 mA. I would use a 4056 charger board available from e-bay a 10kOhm resistor on the charge pin should give a safe current . There are lots of videos showing how to use these on TH-cam. The electronics in the vape cell protect s it from over charge and discharge so if you are not using the cell with the vape sensor the cell should have added protection.

@@toyhacker4647 thanks for your replay

To do it legit and make it officially perpetual-ish one would have the tanks on a pivoting counterweight system. e.g. so as the cycle completes, the primed and holding tanks exchange positions.

Thanks for the ideas. Hope it the video inspired you to try yourself 😊.

The video is about the small round device which contains an integrated circuit which l have used to safely charge the cell by removing the wires from the heating coil and connecting them to 5volts the correct way round! Many vapes now have a USB charging socket which can be used to charge cells. But please don't mess with these cells unless you are sure you know what you are doing as they can be dangerous.

@@toyhacker4647 OK I understand that. But what was the little strip you connected across the battery? Even if you can use the existing electronics in the 'microphone' I would prefer to use a cheap 4046

Afraid it goes on a bit. At what time in the video are you referring to with the little strip (rectangular board) cross the battery? The video was intended for people who don't have a 4056 board and just stick 5v across the cell.

@@toyhacker4647 Thanks for taking time to reply. I know a fair bit about Li Ion ( I thought I did ). I have chargers for 18650 and have used them to charge Li cells salvaged from rejected mobile phone batteries by using home-made connectors to connect to the commercial charger. But the cells from vapes are lipo, no? I used a them in a toy whose own battery was dead. The mains charger for the toy generated 5V and the vape cell was wrecked. twice! Im confused as to how you recharged the vape cell: did you just use a 5V charger? When I did it was a disaster The little device I referred to appears at 20 min 56 sec.

Hi I'd forgotten about the protection board in this video. I solder them onto cells they output and charge on the two wires in the middle they seem to be a 40?? Replacement. I use them on the cells I use in toys. So they should solve your problem with toys charging at 5v. See eBay for examples.
