Saw how that worked in Soviet Union. They will all become of low quality in the absence of competition.

Some countries like Russia and Canada are clearly underpopulated, some like India and China are overpopulated, although even within China there are some underpopulated regions. Each country should decide what is the best for them.

Strange, but looks like only one image per post works.

That's a great idea! Although I accidentally bought a big spool of very strong thread at a secondhand store that will last me a lifetime. Well, in case I don't use it as a dental floss... Hey, this is really working out, thanks again for two great ideas at once! And here's how the finished...

Connected the two 200mm fans with mounting tape plus sturdy sewing thread. Each fan has small flat surfaces on two opposite sides and so they hold together very well. Both fans are powered by the shared power regulator (PWM) I described in the previous post. The maximum power is 6 watts and the...

I use these connectors for all my 12v devices - https://www.aliexpress.com/af/5-5-x-2-1mm-dc-connector.html - works as OFF switch very well and helps with portability.

Both these ones have OFF switch, you can turn it off completely: "5A 90W PWM 12V DC Motor Speed Controller Module DC-DC 4.5V-35V Adjustable Speed Regulator Control Governor Switch" - https://www.aliexpress.com/item/1005001621688969.html The larger is 20 khz and smaller is 10khz. I tried both...

I also became a bit addicted to these computer fans and the reason is that I live in a very hot apartment where heat is coming from the ceiling as there are some hot and not well-insulated pipes running through all rooms. I also own a Dodge Caravan converted into a sleeper, so I wanted to use my...

:) Thanks for the tip, I have found this computer fan saga by SternWake: https://vanlivingforum.com/threads/ventilation-fan-vent-thinktank-calling-out-sternwake.9631/#post-87077 He is right about Maxxair being the best choice for high roof vans, but for smaller vehicles it makes sense to use...

It might make sense for some to have several cheap and quiet computer fans that consume very little power, it is absolutely possible to use automotive 12V to run several of them for a very long time. Also, in this post I provided a link to power regulators and grills. DIY fans for those who...

DIY fans for those who like silence(for cheap): I found a very quiet and cheap 140mm 12-volt computer fan on Amazon: https://www.amazon.com/gp/product/B01J4FUU7Y/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1. Also, you can definitely make it practically silent with one of these power...

When I went from Florida back to Canada, I got into the Buffalo snow storm (in December 2022). I was lucky to find a rest stop with 120v power outlet. They did not object that I used it for 2 days :) I had a 1500/700 old and not stinky ceramic heater in my not-insulated Dodge Caravan and it was...

In fact, I'll just hang it over my head or over my feet on a rope (the shape is such that even such simple knot will hold it perfectly). If the rope won't work because of the random rotation, I'll use green foam-coated wire (for gardeners at the dollar store). ... just tried, with above knot...

I ended up ordering this cosmetic gadget https://s.click.aliexpress.com/e/_DmKhAMb - and to my surprise it cools skin very well even with just one nozzle, with 30ml of water for 15 minutes. Obviously with two nozzles the water will run out twice as fast, but I think it is possible to attach a...

I was referring to this model - https://www.amazon.ca/Operated-Powerful-Operation-Personal-Portable/dp/B09CPRL3NH - but the old one I have has 7 blades. This one has three blades and people complain about the noise. By the way, I just found a gizmo that might be good for skin cooling -...

Just a follow-up to my previous message: 1) tested a water spray for hairdressers - not at all comfortable, plus my product from AliExpress was leaking, but even apart from leaking it's not worth buying. A bottle of sanitary alcohol from the dollar store works better. 2) battery-powered...

Very nice! The key to success is strong magnets :cool: I bought some Strong Neodymium Magnets on AliExpress https://www.aliexpress.com/item/1005003897475023.html - and with them you can do wonders, for example to attach large sheets of Reflectix, or silver tarp, (or Mylar with any backing or...

Absolutely agree with these methods. However I can say a good USB or USB rechargeable fan absolutely replaces a 12V fan, for example I have two from OPOLAR which I am very happy with: OPOLAR 10000mAh 8-Inch Rechargeable Battery Operated Clip on Fan, 4 Speeds Fast Air Circulating USB Fan, Sturdy...

By the way, I think that some electric blanket users should also consider USB Heating Pad(s). I use this one https://s.click.aliexpress.com/e/_AKczuh when I have problem with sinusitis, just put it on my forehead with help of sleep mask or headband and sleep all night(well, I also put some thin...
