How dangerous would it be to connect 2 or more cells in parallel? The problem with vape cells is that they are quite small. Could the stronger cell cause the weaker cell to blow when equalizing the charge without a current limit?
@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?
Nice video, thanks for this info. Just picked the same drill from the recycling bin and it is dead. I'll check to see if the same component is burnt. How would you go about removing the variable speed from the power supply?
Good video. I have made enquiries about getting that gear 3D printed and get the .stl file loaded into the github repository of Meccano parts. I'll let you know if anyone does it.
@@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.
I thought of this idea bout two weeks ago august 1st 2024 when I heard a guy has 50 horses and never enough hay. I thought of animal abuse by accident and wondered if horses could get falled appled as treat once in awhile to be kind to gods mammal family. Good to make more money on apple farm and make cider or have "corners" of farm as spoken about in bible. Corners go to poor or animals.
I like these little boards and use them a lot. I have no reason to fully understand them but I just watched pt1 & pt2 and a gentle breeze blew some of the fog away. I'm just about to stuff one in each of the solar lights I bought that appear only to have charge protection chips - 8pin but sanded tops with no hint of a number, classic AliX bargain basement junk with soldered wires on the unmarked lithium cell. Fascinating channel. You earned my subscription. Thanks.
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.
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.
Very informative, thank you! I am working on a project and I want to replicate the transparent display effect of this toy. I've tried tearing apart a 7" raspberry pi LCD display and although I stripped off everything including the polarizer, the screen itself is still dark and blurry... only vaguely transparent if I can call it that. What specific kind of LCD display do you figure they used?
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 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 RU-vid. 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.

an easy way to cheat would be by adding some sodium bicarbonate to the tank's first then small amount of vinegar to the input solution, need dark liquid to hide the bubbles.
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.
The led (microphone) It’s a simple plastic combustion chamber when inhaled it turns on. There’s no internal charger on most disposables, it’s the battery that’s recharged @ 3.5-5v done disposal vapes have recharge options, usually via usb-c
I got lost half-way through. You use that long rectangular board to do what? It connects to the battery( cell ) and there are 2 output pins. OK, now how do you now charge the cell? Via a 4056?
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.
Thank you for the in depth explanation, kept at a level I understood. I have an idea for a use of the timer feature. I will have to run some tests to see how accurate the time period is.
