I got one of those USB C cables with the power meter in the connector after seeing on your channel. I was super skeptical after seeing the $4 price free shipping, but I've been using it every day now and it's really good! The connectors are even anodized aluminium and the power reading is pretty accurate. Great recommendation!

[@JaredConnell]

I got a similar one from Amazon and I love it

[@PiratWeber]

@greatscottlab did you check if the MPPT controller wasn't broken? The wind turbine itself looks fine and may be worth it. I just suspect that they had to cheap out somewhere and that could have been the mppt controller. Also the spot welder looks really hackable. Maybe a microcontroller and some LCD display can be added to make it a bit more user friendly. Love the series, please continue doing them!

[@greatscottlab]

I might check it out in a future video

[@AndyFletcherX31]

[@guycxz]

I find using a large amount of flux helps me melt the varnish around enameled copper wire. I don't know whether it's a chemical reaction, faster heat transfer through the flux itself, the solder wetting the wire sooner, which facilitates a greater rate of heat transfer, something else, or a combination of all of the above.

[@teravolt1195]

It's said that you should buy a higher generating voltage wind turbine than you're going to use it for as you're likely to get actual power to charge with at lower speeds, in other words, actually work. Not sure if there are MPPT wind controllers available but you could always put a zener on the gen output and if the solar MPPT rejects power the gen voltage will come up and go through the zener to a dump load to prevent no load overspeeding of the turbine.

[@yacce4463]

[@jovaraszigmantas]

I could be wrong with this but I think the gaps in the nickel strips located on the battery terminals are used that you place the spot welder probes on different side of the gap and thus lead the current to go through the battery and not the nickel strip. As I said I am not sure but, but in all of your footage you placed your probes on one of the sides.

[@greatscottlab]

Hmmmm I think both way should do the job

[@TheUnknownCatWarrior]

Would be interesting to see you modify that wind turbine. Weather its the dodgy motor or the charge controller.

[@readnotify971]

@8:43 You are doing it wrong. The purpose of the gap in the nickel is to force the current to go through the cell's cap - which means you're SUPPOSED to put the contacts either side of the gap, not, as you're doing, always on the same side.

Tbh sleep quality is heavily affected by placebo, and when you do it you wanna do it properly, so you go to sleep earlier and maybe drink a glass of water. So yeah people are probably getting better sleep, but this generator or a magic stone or some baby sock on your finger would probably work all the same.

[@resphantom]

It is said that 7Hz infra-sound may cause destructive interference with your inner organs, such as your brain, heart, liver, ect. Since every object has a resonating frequency, every object also has the opposite, which is a destructive interference. Almost like breaking glass with a specific frequency of sound.

That spot welder performed well, and it's very low voltage of course, but holding two bare metal probes from an unfamiliar black box is not for me. The most likely problem is accidentally shorting them, unless they're covered by clear shellac or something.

Just gotta get that cheapazz spot welder. Cells waiting to make two battery packs! As a side note, that wire spool looks almost like something I used many years ago. In the days of wirewrap, for home made boards there was a tool called Solderwrap. Instead of using sockets with long tails for wirewrap, you used regular PCB sockets and perf board. The "pen" was like this one and the enamel wire was strung from IC sockets and discrete components via "channels" consisting of plastic strips with "pegs" to route the wires between rows of sockets. Making it look like wirewrap, but soldered. Still have one in the back of my tool storage....along with wirewrap tools! What was old is new...AGAIN.... (signed) Retired octogenarian chip designer

I think you were a bit hasty on the Schumann Generator. Now, I've not used one, but I have seen similar kinds of things that really work. Not everything works for everyone, and if you dive into the scientific literature, you'll see that very clearly. That the Schumann Generator didn't work for *YOU* doesn't mean that it won't work for other people. I've looked at them before, but really, you've just peaked my curiosity just up past the BUY NOW point, so I'm going to buy a few and see what happens. 😉😝😇 PRO ALI TIP: Always buy more than one from different vendors as results vary for what are ostensibly the same things. e.g. I recently bought some ostensibly identical RF splitters for antennas from several AliExpress stores, and they were ALL different in one way or another -- one version had an entirely exposed conductive back - another had different positioning of the SMA connectors, and another was the only one with the SMA connectors soldered on both sides of the PCB.

[@ash0787]

if you wanted to install solar panels outdoors for a small generator( at the end of my garden ) instead of on the house roof and connected into your mains, then use the power indoors in your house during a blackout / high prices etc how would you go about that ? portable DIY power station or a long cable running mains from an inverter back to the house ( safety issues ), or use e-bike batteries, charge at the solar and then carry them when needed to an inverter indoors ?

You connected a higher dc voltage to the IP2368 pro module causing it to burn.By default the max input voltage is 16.8volts. Resistors need to be replaced to adjust for higher input voltage.

[@AnOrangeECat]

I own one of those black box spot welders, recently welded a 7S2P battery pack with it on the lowest setting with normal nickel strips. Strange that yours didn't have heatshrink tubes that covered the copper handles though, because it was listed on the Chinese instructions to not contact both together.

[@nerdytech7287]

you need sustained consistent toque from wind make the charge controller work. it will slow down as it will ramp in more amp out to battery and try to keep the blades spinning at low consistent speed regardless of the speed of the wind. faster wind low rpm lots of amps in to battery. slow winds same rpm but less amps. but controller slowly ramps that in to minimise damage to turbine and itself. you should only get very little if at all power if you are trying to hand spin them no matter how fast you spin them. attach it to a Moter and you can test it. .

[@ericblenner-hassett3945]

I am surprised that the first item did not end it's life as the base of a Tesla Coil. The design is that of most bases of tesla coils and with your new enamel wire dispenser, you just need to use up a roll of toilet paper to get the cardboard as the base for the secondary winding. Depending on the polarity of the coil, you could " cheat " by having the secondary contact the center of the base coil that looks to be an exposed trace. Thank you for looking at these products, you may want to look into the cheap ceiling fans that are under $30USD as some of them are able to be converted into actually working generators.

It's not the 100W that ruins the IP2368 Mini, it's the fact that you connect it to a battery pack with a voltage of 18V. According to the product description, it can only be connected to a battery pack with a maximum voltage of 4.4V. You should read the product description carefully first.
