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.

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.

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.

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.

Supercapacitors are extremly poor filters. They turn from a capacitor into a resistor already at a frequency of 100 Hz. By comparison, electrolytic capacitors suffer this at 100 kHz, tantalum capacitors at 1 MHz, and ceramic capacitors up to 100 MHz. Typical power supply frequency 30-60 kHz (can be up to 500 kHz in case of dc-dc step down converter at end, which all quick charge bricks have). Although consumption jumps that lasts from 5ms to 1s supercaps can smooth out

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.

The voltage shouldn't have dropped at a higher load with the capacitor. That was entirely a problem with your supply or cabling. The only effect an underrated filter capacitor should have is increasing noise at higher loads. Its pretty common for 5V usb power supplies to drop quite a bit even far from their rated current. The only way that supercapacitor box would affect output voltage is if its got a DC/DC converter inside it as well.

I'm from Poland and we were buying A LOT of stuff from AliExpress untill the Vat and dolar went 25% up. At least now the shipping is quite quick - under two weeks

So true, search engine is so broken, sometimes the entire a search result product page is completely devoid of the keywords even though the product exists and has those keywords in the title! So frustrating! Google can find it but the AliExpress search can't!

This was fun and useful. I hope videos like this mitigate the trash problem at least little bit!

we love this kind of video, the jigsaw adapter seems really handy, and the prank generator looks very funny....

Aliexpress is pretty much one of the best suppliers for mechanical keyboard components of all things. Cheaper clone keycap sets, a wide selection of switches, and a lot of half decent board kits for reasonable prices. You can even find proper fully CNC aluminum and wood cases ready for the rest of the components.

Now a days aliexpress is very bad . In Aliexpress standard shipping the courier guys stealing the parcels and updating as delivered. So we don’t get the item and refund After may month this year i lose approximately 100 usd 😢😢😢

Great video, interesting products you've found! BUT: That chainsaw thing looks super dangerous; such a sharp blade and very difficult to control. Definitely a NO NO if you want to keep all your fingers/toes intact!

Great topic for a video. I hope you consider making this a regular event on your channel (every 6-8 weeks maybe?)

One of my favorite thing to buy from aliexpress so far has been these boards for converting old laptop displays to hdmi monitors. Used quite a few of those and they don't cost much.
