      Back in the 60s we were doing something like that with a plastic soda staw, and rtv caulking. Minus the heat shrink, and it was for automotive applications.
      We would slip a 2 or 3 inch piece of soda staw over one wire, solder the other wires to the first wire, and slide the straw over the connection, and squirt the rtv into the straw. In a wet environment it was the way to go. At least,, we didn't have any problems. ..

    As someone who's been thinking about getting back into hobbyist electronics for the first time since I was about 12, these videos have been an absolute goldmine for simple, useful tips and bucketloads of information, free of the oft-seen "you need £200 worth of tools & equipment before you even start" gatekeeping of hobbies like these. Like here, strengthening (and I suppose insulating too) bare leads using nothing but a hot glue gun and some heatshrink! Simple but brilliant.
    Thanks for your work & expertise in putting these together in a way that even an idiot like me can understand. And if you happen to be reading comments on this old video, I must ask where you get your equipment from, particularly those micro molex connectors? The only places I can find sell a single pair for about £2, or a million pairs for £20. Either way, a bit of an investment for a single project that I might give up on halfway through! :)

    I love the TP4056 modules. I converted pretty much all my LED flashlights (and the vintage ones that weren't originally LED got an upgrade) to use lithium cells using those modules to have built-in charging capability.
    It takes only a couple of minutes to set everything up and I've got quite good at embedding the circuit inside the device.
    Another fun thing is to restuff alkaline batteries (like the 6V lantern battery or the 4.5V flat square ones) with the lithium cell and circuit to make a completely invisible and reversible mod.

      And if you buy a BL-5C type battery for a device and it's too thick, you need the thinner BL-4C instead. For actual, genuine nokia batteries the BL-5C would be 1020mAh and the BL-4C 720mAh. The fakes/knockoffs usually claim completely ridiculous capacities (I've seen anything from 1500-2900mAh for a BL-5C, which isn't possible in that physical size) and are actually far below the original batteries' rated capacities (usually 500-800mAh for an okay-ish BL-5C clone, less for really crappy ones)

    Snip the tip off a spear-shape probe with a side cutter - a real one, not one for tiny component leads, the cheap component snips are too soft) and it won't skid as much on the tab

    I have a set of 100 warm white lights. They were powered off three AA cells and a flasher circuit. Funny thing was the circuit boosted the voltage to something like 24V and toggled the polarity for the effects.
    I eventually replaced the controller with a small 24V transformer and a 27K resistor. The lights now take about 0.3mA and something like 7mW for the lot. At night they still give enough light for me not to walk into things in the room whilst still enabling me to see the stars through the windows!
    It is impressive how efficient LEDs are these days, I remember my first ones in the early 1970s, 10mA and you could see red LEDs if the room wasn't brightly lit :-)

    Nice. I have a few old Lithium cells lying about.
    On a similar note I recently resurrected some old hair clippers where the 3xAA NiCd battery pack had died. I replaced the innards of the charger with a crap USB 5V PSU and rehacked the clippers to use a 18500 Lithium cell with one of those charger/protection circuits you used. They work brilliantly now. Charge very quickly and last for ages per charge and a bit lighter too. The charger weighs almost nothing compared to the big old transformer that used to be in it.
    I now use the clippers to trim by little beard one a week :)

So Basically its a big glowing ball when i put it on the floor with the light inside it. The LED changes colors slowly out of one single LED and with the diffusing of the lamps spherical dome that sits by itself on the floor, as if some kind of colored crystal ball, its a nice nightlight for ambiance. I will convert to these batteries next and i like the connector idea of it as well. :)
