Integza is a great YouTube channel.

Integza is hilarious! In some of his older videos (before having real sponsors) he would create fake sponsored segments. Those were the best!

I'm very excited that he's got a metal 3d printing sponsor or whatever. He's been massively held back by not being able to make metal parts. He did the dyson blower in plastic basically the same part in this video. It may become less rediculous with him constantly burning up plastic but that could have gotten old. I'm hoping / betting he won't be held back by his inability to design parts that won't melt metal.

I enjoy this guy's MacGyver style, but I think he'd get a lot further with his projects if he invested some of his time and youtube money into a small machine shop and requisite skills.

If you're into homemade jet engines, check out Igor Negoda's channel (Игорь Негода) It's in Russian but the autotranslated subtitles are usually comprehensible: https://www.youtube.com/watch?v=dYFYZ-g7fzA

That Russian one goes beyond the jet engine and he actually builds a plane around it and flies it too. Highly recommended.

grogenaut2• 3 years ago

I don't think he has the space or the money for it. I'm hoping his workign with a metal 3d printing company will be an equivaletn.

He doesn't have the money for it.

There's a 20-25 year old video of a Slavic-speaker test firing either a ducted fan or microturbine with an afterburner complete with adjustable iris. Fuel consumption was insane, 250 mL or more per second. I haven't seen any hobby afterburners with fuel injection, iris control, and water injection.

Jet engine or just a blowtorch? Didn't seem like it had much thrust at all.

I mean, I clicked, but that title is not accurate =)

In jets, the compressor is usually powered by a turbine, but there's no turbine here at all. Most of the thrust is coming from the electrically powered compressor. Would've been interesting if he had been able to measure how much additional power the flaming gas added.

It can still be a 'jet engine' like a motorjet which is basically a reciprocating engine spinning a compressor.

or just link directly to the video https://www.youtube.com/watch?v=1zSU2kLLXQY don’t need the hackaday fluff

I always cringe at videos like this where they use no safety equipment… waving his mini jet engine (which is really a blow torch) on a stick inches from his face with no protection seems like a terrible idea.

This is Integza, someone who has a wild amount of experience developing hobbyist jet engines.

Apropos of nothing, back in 2016, I laughed at the idea of spending $500 on a hairdryer. Fast-forward two years and I bought the Airwrap in 2018 (which was even pricier but it also curls and styles) and then got the regular hair dryer too. I’ve also bought the hair dryer for my mom and the Airwrap for my sister.

Anyway, it’s absolutely worth the money for anyone who has long hair (tho my husband likes it too, as does my dad) and I love it. (Just be aware you can’t use the US version internationally or vice versa b/c of voltage stuff)

Not sure how it is as a jet engine but it’s a great hair dryer and also frankly, as a high quality heat gun.

Gerard02• 3 years ago

Could you please elaborate what it does "better"? I just bought one for my partner since she wanted it but I don't understand what the advantage is!?

filmgirlcw2• 3 years ago

Very nice of you to get it for your partner, I hope she's enjoying it!

It’s significantly faster, and not just a little bit, at least twice as fast. When you have long hair, that matters both for time and for precision when trying to achieve a certain style. It also matters because you don’t want to spend a ton of time with super high heat on your hair because that causes damage. The Dyson dries fast and is hot, but is not as hot as some dryers, which is good for preventing heat damage. I have long hair and being able to cut my blow dry time in half is a huge boon to just my daily routine. The Airwrap, which is a separate product (but has a dryer attachment that acts like a mini version of the regular dryer), dries and curls your hair, which genuinely is a huge achievement because I don’t have to use a separate curling iron. I just start to curl while my hair is still damp and it’ll set and dry my hair appropriately. It won’t replace a curling iron or rollers in all scenarios, but it’s incredibly nice.

Beyond speed, you’re also getting a very even output of air at whatever temperature you’re choosing. This also helps with making things smooth, getting rid of flyaways, getting more volume. There is a flyaways attachment that uses the Coanda effect to keep hair looking smooth that mimics the effect you get if you pay for a blowout at Dry Bar or something. It’s also well designed and hugh quality (attachments attach with magnets and it’s light enough to use in your hand but doesn’t feel like it’s made of junk).

I bought the Airwrap first but got the regular dryer when there was a sale and I had a Dyson owners 20% off coupon. I’ve found myself using the dryer almost every day, whereas I use the Airwrap a few times a week.

Like, yeah, I’m not arguing that everyone needs to invest in a $430 hair dryer (what it costs now, the Airwrap is like $600 if you get it with all the attachments) but just like there is a difference in a $500 laptop and a $4000 laptop, it’s just a higher end/more premium tool. Like, it’s similar to a KitchenAid standing mixer. If you just buy a normal $50 mixer or whatever, you’ll be able to beat your egg whites and mix your stuff just fine. But once you use the KitchenAid, you suddenly realize that there is a better way to do it that is more powerful and efficient. If it’s worth the money comes down to the individual and your budget.

Does he evaluate the achieved thrust? I suspect it to be lower than a conventional jet engine, though I can't qualify that suspicion.

anaganisk• 3 years ago

Look at CFM rise engines, they're essentially turbo fans with huge bypass ratios than conventional jet engines.

aVe did a great teardown[0] of a Dyson hairdryer. He was contemptuous in the beginning because of the ridiculous price, but totally nerded out over the motor.
