Another work light with weird circuitry (with schematic)

I've looked at a few of these before and they all seem to have some weird circuitry twist. This one initially looked almost identical to the blue Aldi unit, but the circuitry has some weird bits that are actually quite clever.
What's not clever is the current the LEDs are being run at. With a freshly charged battery the current draw was:-
High (2 LEDs lit) 3.8A - 11W
Medium (1 LED lit) 3A - 9W
Low (other LED lit) 1.6A - 4.8W
When the zero-ohm links are removed and replaced with one of the 1 ohm resistors the current drops to:-
Both LEDs lit:- 1.75A - 5.25W
One LED lit:- 1A - 3W
The light output is still very useful, but the light runs much cooler and has a considerably higher run time on a charge. That makes it better suited as a rechargeable light source during these turbulent times.
Supporting the channel with a dollar or two on Patreon helps keep it independent of RU-vid's quirks, avoids intrusive mid-video adverts, gives early access, bonus footage and regular quiet Patreon live streams.

Yes, seal script. The characters share the same ground line as the rest of the script on the board, so that gives the orientation. The Chinese are not above making a piece of text also an illustration. Mostly, it looks to give the impression of a "chop" mark, the equivalent of a signature, in a rough way. The text is clean, but the border of the surrounding field is quite rough. Odd. Sorry, not fluent, I can look up words, but I'm decades out of practice.

After some more research it turned out that this is the work of a Chinese artist from the 1980s who re-imagined a lot of family names in this ancient style. So it is made to look really old but actually isn’t. Nobody from the PCB manufacturing contacts recognized this as being a thing at a certain factory or something like that. Maybe just the designer having fun putting his name on it 🙂

My friend in Kyiv decided to construct a makeshift home light for the periods of power outage (they take place daily, often several times a day). He's got almost no spare parts or modules on hand, but at least he can salvage something from his earlier projects, and between the blackouts he can use his soldering iron. I know a couple of cheap rechargeable lights from a dollar store could save him (especially if they take 18650 cells and allow for replacing them), but when everyone in a big city faces this situation, they certainly don't have enough on the shelves.

Looks like a decent portable light, and I agree that the resistor values should be altered to give better battery runtime. Even if you don't consider the heat dissipation, pulling 3.8A from a 2P Li-Ion battery pack is not going to help it in terms of battery life (just over 1 hour?) and battery longevity (will lose its capacity faster).

The resistor divider on the USB data lines comes from the original iPod era and it uses it to detect that the device was plugged to a wall wart charger instead of a regular PC port, where it could only suck 500mA while on the charger it allowed 1A. Nowadays the current rating is set by the USB C power delivery system I believe

A pile of things now will just keep trying to draw what they want until the voltage starts to droop. I have some neat 9-36v input USB power boards with 4 USB ports on them that will happily feed 3A into each pair of sockets. (Particularly handy for driving USB powered SBCs.) Mind you, I did push one up to 5A before it finally let out the smoke. It's always handy to destructively test any hardware you intend to use. Fun, too.

"power outages around the world" are you perhaps mentioning South Africa as well. Wr currently have scheduled power outages. Wr even have different stages. If our power capacity is good then it's stage 0 . And we can get up to stage 8. Basically the higher the stage the longer and more power outages wr get in a day at a scheduled time. Right now we are at stage 4 and in the town I'm in at the moment (each towns or city's scheduled time is different) that means we have three scheduled power outages that last for two hours each . We call this loaf shedding because we're shedding the load of different towns at different times. But as it is our power infrastructure is pretty fucked.

I've bought a couple of these types of lights using removable 18650 batteries. I use 3400mAh 18650B in them. They are superb for ice fishing at night. I was worried about the effect of cold on the batteries, but they last so long, and I think the light heats up the cells, so it isn't as much of an issue as I had feared. They don't keep you as warm as an old Coleman fuel lantern, but you don't need to carry a heavy glass lantern, and stinky fuel.

I'm a quality control engineer in a German company and i noticed lately that some RCBO typs in combination with Socapex (6 channels) a remaining voltage of 20~30 volts. And it's not a capacitive effect because it does not change if i move wires away from each other. Do you have any experience from the entertainment industry (Socapex) standard. About the matter? I know it's ok as long as it's below 50v. Thank in advance for reading and commenting or maybe video about the subject
@bigclivedotcom
@bigclivedotcom Год назад
In socapex you have six circuits in very close vicinity in a multicore. There are capacitive coupling effects between the cores when measured with a high impedance multimeter. Testing with a proper electrical tester would add enough load to shunt the effect. Dimmers also have high leakage when off due to the snubber networks.

I wouldn't mind so much if there was a dedicated button or sequence to get to the flash mode. I haven't a clue as to what the heck that thing was printed on there. Usually I pick up on that kind of thing fairly quick. That one has me thoroughly baffled.

It's worth remembering that as LEDs get hotter, their conversion efficiency of current to light decreases. So much so, that at some point they may actually output less light as the current increases. Below that point the light output is a relatively linear function of current, so reducing the current through the LEDs by substituting larger resistors is unlikely to reduce efficiency and may possibly improve it. Given the penchant for Chinese manufacturers to drive all the components as hard as they can get away with, that sort of mod makes a lot of sense.

@kenaston4220 Год назад
Thats a very interesting point. my one starts off bright and then dims down. If I switch it off and back on, it comes back bright. I wonder if I should back off the current a bit and have a more stable output?
@RexxSchneider
@RexxSchneider Год назад
@@kenaston4220 If it's dimming over a relatively short period (a minute or less), then it's probably a thermal effect, rather than the battery voltage dropping, so there are efficiency gains to be made by reducing the current and/or putting a better heatsink on the LEDs. Perhaps test the theory by blowing cold air from a fan over it?

It's a good question. Mosfets are also transistors (metal-oxide-semiconductor field-effect transistor). The other is a bipolar transistor. One even if there is no part number you can tell them apart by testing them (preferably out of circuit). The bipolar (NPN or PNP) will have two 0.6V diode drops when tested with a multimeter.

The resistor network is not to "stop Apple phones trying to suck as much current as possible". It is actually to _allow_ them to charge using higher current than they would otherwise. If you plug a USB-compliant device (including an Apple device) into a port whose data lines are not connected to anything, it is not allowed to draw more than 0.5A according to the spec. These resistors are configured to tell Apple devices that this charger is capable of supplying 1A of current, so it's OK for them to pull that much. However, I'm not sure why they didn't just go with the more standard "dedicated charging port" indicator of just shorting the data lines together, though, as that also works even with non-Apple devices, and AFAIK Apple devices understand it just fine too (since it's part of the USB BCP spec)..

Relying on the protection board in a battery pack to limit the charging voltage is a very bad thing to do. Protection circuits are generally designed to allow the maximum voltage that won't actually result in rapid destruction (fire!) of the cells. It is expected that they will allow the main charge controller to reach its maximum setpoint without cutting off charging. That means that the protection circuit probably won't do any good in this case and the battery will be overcharged. It takes surprisingly few overcharge cycles of surprisingly little excessive voltage to significantly shorten the lifetime of the battery. Undercharging will result in greater life, both in terms of number of cycles and total energy deliverable over the lifetime of the battery.

Hey i know this might not be the correct video to ask you, but i have a NI--MH AA Battery charger it is a Sony Cycle Energy charger and just a couple of days ago it suddenly stopped charging my batteries. I dont know much about electronics but i think i know what the issue is. I opened the charger and in the beggining of the circuit next to the prongs that connect to Mains there is a component that looks like a Resistor and it looks burned and has a tiny crack in the middle. Everything else in the circuit after this component looks fine. Again sorry to ask you but how can i buy that component. Do i look it up as a Resistor? Do they have a certain rating? This is what is printed on the board next to it : RF1 100HM 1W And it also has colored bands but only the outer ones are distinguishable since it is burned in the middle. They are colored GOLD and BROWN.
