In this video we will be having a closer look at 8 different products I got from Aliexpress. Aliexpress is famous for featuring the newest products/ICs when it comes to electronics but finding those can be a bit difficult. So I tried finding the hidden Gems not only electronics related but in general what I think could be useful. Let's get started!

Aliexpress takes anywhere between 4 weeks up to 4 months to deliver stuff to my house. i love it, because 2 weeks after i order stuff, i completely forget about it, and then out of nowhere a new package arives every week for about a month (depending on how much you order). it really feels like its christmass

@yuxuanhuang3523 Год назад

I like your attitude. For me the packages should come in three days and if they don't I start getting impatient. But it feels really good to be able to order something you missed for a project and get on with it without waiting for too long.

@Arcygenical Год назад

Absolutely this. Especially after a few drinks, I buy myself the coolest stuff. And I've never had an issue getting a refund on poor quality or broken items.

@hoggif Год назад

The pump seems a sentrifugal pump. They never suck, they only push. You need a line wit no air in it, an u-shape to keep it always primed or a oneway valve to keep air getting into it from the output side (especially when the pump is off) after priming it. Any air in the pump will make it not pump.

@comp0smentis Год назад

lol been sick in bed but I got up so I could read text well enough to write nearly exactly this. This^^^^!! Well said.

@Henning_S. Год назад

Yes, a check valve will definitely work if the the pump is always filled with water, but I think it is a vane pump because you can see the input shaft is offset from the center of the casing. A vane pump is potentially capable of sucking air, but it needs to be made with pretty good precision.

One problem I have with AliExpress is I can't group products together for a smaller shipping fee when buying from the same store. It's always full fee for each item shipped, even when they actually send them together in one package that costs them the price of one of the shipping fees.

@stanneh1978 Год назад

Ask for a refund. take pics of the parcel and request all but one shipping back.

@Slodin 11 месяцев назад

because the shipping fee is part of your items' cost lol...they inflate the shipping fee to lower the product listing price. Seems more attractive on the listing. To them I think it's by weight onto a huge freighter, so it doesn't really matter it's the same price (or close) for them.

I understand the love/hate relationship with aliexpress. I ordered around $80 worth of ICs for a synth I was designing and none of the ICs arrived and on top of that I didn't get my $80 back. You really have to be careful when ordering because you may think you're ordering from a company who you have previously had a good experience ,but in reality is just an unrelated company using the branding of a company with a good reputation. That being said the thing I love about aliexpress is that it's a great place to find aftermarket/obsolete/vintage ICs and very specialized tools/ test sockets/adapters. I found some very nice test sockets that would have been costed an arm and a leg on amazon and some used vintage YM2203 sound generation chips that were completely unavailable on amazon or even digikey.

A lot of people here in Brazil complain that delivery times are very long when ordering from China. However, it hasn't been uncommon for overseas purchases to arrive faster than some bought from local retailers, especially when using private couriers (instead of the Brazilian postal service). The average delivery time from Aliexpress purchases has been around 2-3 weeks (even though some may took waaaay longer), while I've had some local shipments that took over a freaking month to arrive.

Pumps often have a much smaller rating in sucting than they do in pressure. Try using a piece of threaded rod to elongate the shaft of the pump and dip it in your pond. You can than drive the pump with the drill though your rod which should provide enough pressure to pump water. Thats why water reservoirs have the pump at the bottom and it can still deliver up to 20 bar of pressure which means it can lift water up to (theoretically) 200m. No pump however can suck water from 10m as that would require absolute negative presure (-1bar) which also means perfect vacuum.

Der Pumpenwirkungsgrad bei der "Drill Powered Waterpump" dürfte einfach nur extrem schlecht sein. Bei einer Höhe von 1m entsteht (unter Vernachlässigung des Schlauch-Druckverlustes) ein Höhen-Druckverlust von 990 kg/m3 (ca.) * 9,81 m/s2 * 1m, was ca. 9712 Pascal entspricht. Nimmt man den Schlauchquerschnitt bei ca. 5cm an und eine Strömungsgeschwindigkeit von ca. 3 m/s, so ergibt sich ein Volumenstrom von ca. 0,002 m3/s. Die benötigte Stutzenleistung, die an das Fluid übertragen werden muss, wäre dann ja 9712 Pascal * 0,002 m3/s = 19,4 Watt, was die Bohrmaschine ja locker leisten müsste. Denke also dass das Pumpendesign (Laufrad o.ä.) einfach schlecht ist.

Hey guys, tip from someone who does a lot of importing from China, If you're ordering from Ali-Express or other Chinese websites, especially if you're ordering large quantities, is to go through an agent!!!! I seriously cant stress this enough, they offer so many more protections and make it so much easier to order from there.

11:08 and of course, you simply power the hand drill with the output from the generator! Genius!

Hi GreatScott, Nice practical video ! I'm looking for a quality step-down DC-DC converter (accepting possibly 60V on input) and able to sustain continuous 3A use. I bought a lot a such converters (on ebay/ali) and was very disappointed with sturdiness. They were based on the XL6009/XL4015 chips. they were also supposed to self-regulate when overheating but most of the time, I found them lying with the PWM chip burnt... If you have suggestions.... (thanks)

Nice, I buy way too much stuff from aliexpress. It's nice to see a random collection of stuff in action. Look forward to more videos like this. I'd like to see and good water tap generator.

Funny products! Hope you will find more interesting circuits to test and explain the reason why they work or don't work.

I'd love to see some suggestions for a lipo battery charging and protection circuit if you can find any.

I have bought a number of various amplifiers, ranging from 2x3W to 60W. The small BTL a,ps can be powered by a Li-battery and sounds great. I have bought some clocks, but always loose the descriptions how to set them up. 1-, 2- and 4-channel programmable timers have also been used and tested. The best thing I bought was GOPHERT bench supply supplying 0-30V at 5A. Have served me very well for several years now.

there are powerbanks with the additional cables for giving a jump start for your car battery. they seem quite interesting and very handy to have them lying around in your car for multiple purpose!

7:37 - If and when this white plastic breaks, you can make it from metal easily, take bigger lager, put it at angle and spot weld it. 11:47 - Different antennas are for different ranges. That circle thing is also antenna. Try it again in house with wireless internet shut down.
