your demonstration of what happens when you turn the fan off and let the elements heat up actually demonstrates why you should never block the back of a hairdryer.

The wire sags because it expands as it heats up! This principle was used for the Sunbeam radiant control toaster.

you should add a light sensor that detects when the motor is spinning and shuts off the heater if the motor stops unexpectedly (like if something is caught in it)

One thing to keep in mind: infrared thermometers do not work accurately on shiny surfaces.

These videos are so enjoyable to watch! :) keep making them

Ah, my Arch nemesis, the Heater Fan! Our battle will be legendary!

A ceramic heater would be good because it has a positive temperature coefficient, meaning its resistance raises as it heats, so it literally cannot get above a certain temperature In fact, this principle is already used in many space heaters

use some sheets of thick black paper to measure the heat, shiny surfaces are hard to measure with laser thermometers or infrared cameras.

Would you happen to be able to use those steel parts to make a turbine that can handle hotter gases than air?

Adding a heatsink might have been able to help radiate the heat from the 12v heating element in the beginning of the video.

7:15 the death spring

what you have created is, at its core, similar to what a central heating air handler does, and demonstrated why it's very important to include multiple redundant limit switches to prevent dead blower motors (or bad capacitors) from inadvertently setting your house on fire

its always a good day when Jamie uploads

thats not how infrared thermometers work. the detection area is conical shaped. at a small distance you can already not measure the temperature of small things. it will take the average of surrounding temperature and the temperature of the part over the whole detection area, the object you are trying to measure needs to fill up the entire detection area (which size depends on how far you are from the object). you can also not measure bare metal since its very reflective in infrared and you will mostly just measure the ambient temperature again. youll need to stick some capton tape on bare metal to be able to measure it. the laser is just a guide. its not actually measuring at just the laser dot. emissivity is also a thing

We need a video showcasing your lego collection!

Next you should make a lego AC! that actually blows good cold air

You've hit on the design of a good space heater. The amount of heat that a heater puts into a room is entirely dependent on the wattage. By increasing the air speed, you put out a lot of warm air instead of a little hot air - and heat the whole room instead of the spot right in front of the heater.

thats really cool I have wanted some of those mettel parts for so long, evey video you make me want to mess with what ever was in the video.

Whats really cool is if you measure the voltage at different points along the heating element you can get different voltages. (commonly known as a voltage divider) infact this is often used to power the fan motor in hair driers/fan heaters and other things so avoid the need for a transformer.

8:30 *Gets a wire hotter than most baking temps close to the upper limit of an oven* "Wow thats hot, I cant even put my hand above it" well yeah because its at baking temp. Either way interesting video, keep up the good work.

damn only 215 comments for such great video?!

Great idea, need this thing in my house on my desk right now ❄

Run the motor off the same power as the heater or at least have a board with a MOSFET to kill the heater voltage when the fan voltage isn't detected. But then you're leaving Lego so the light sensor in the other comment is a better "for fun" idea

6:54 wow that is glowing *bright orange* based on the colour of the wire it could mean that the wire itself is reaching 1000C!

I wonder why this channel does not have 100k you are really good at making interesting videos with legos.

back in canada, theres not much snow left, but it would be cool if you could make the fan powered with an air engine!

Love seeing a video right when it comes out

I enjoyed that, James! Good job!

My father also uses those chompy alligator clips

4:44 Surf shark pry’s eyes, I am so scared for my life!

Instruction unclear, house burned down

this was awesome i have all kinds of useful gadgets that I built for my room and I use them all the time every single day. can you do more experiments with pneumatic engines and power generation making a generator with magnets and magnet wire please? I find those creations to be the coolest things ever

Next video: I made a working Lego jet engine!

Make a Lego wind tunnel with some experiments!! love the vid btw

Just subbed! More builds with the metal technic parts please!

You should try making this but only have it run on Lego battery boxes only

I spy... ...With my clean windshield... ...A fire hazard! **Grabs fire extinguisher**

If u would put the heater behind the fan, it would actually just suck the hot air to the blades and push it towards you, with ur design it blows cold air to the heater and reduces the temps on the coils, so ye

The next most logical step is a Lego marshmallow toaster

As long as you don't exceed ~70-80 °C (158-176°F), the Lego should be fine. Since Lego is made from ABS which starts to soften at around 105°C (221°F), and melts between 190 to 260°C (374 to 500°F).

You could have connected the source current INSIDE of the risers so that they wouldn't be exposed to hot nicrome wire.

This is really cool, nice video

7:59 i was amazed at how orange the nichrome got also, 0:14 Can you please tell me the link for that heating rectangle thing to i am interested in electrical stuff or anything that has to deal with electricity.

Hey! Awesome video! I was just wondering, do you have dc?

Your thermometer doesn't show "correct" (they are correct, but for different emissivity) temperatures because you have wrong emissivity setting. Your thermometer has emissivity set to ε = 0.95, which is too high. Aluminium (which is the material of the heating module casing, I guess) has ε = 0.1 - 0.2 and stainless steel has ε = 0.35. Nichrome has about 0.87, which is why you are getting more accurate readings, but I guarantee you, that the steel bolt didn't have 33 °C. But it was pretty cool and interesting video nonetheless, keep them coming.

Never regretted subscribing

Where do you get the resources for this.

Add some sort of heat sink 0:46 0:49 0:47 0:49

How did you get the blades

Remember: if you melt plastic do it in a very well ventilated area. The fumes are very bad for you

It could work much better if you put the heater in the back of the fan

ngl those filters for surfshark sound alot like ublock origin

if you positioned the element lower, so the fan blows the hot air without cooling the coils, would it be more effective?

make an atomatick marsmellow toaster that toast them perfectly

Very underrated channel

My intrusive thoughts want me to touch the funni glow wire

love it

I literally just turned on my fan space heater and then this video was released.

The video is very interesting but a bit dangerous

WHERE DO YOU GET THE RUBBER NIPPLE THINGIES. HOW DID YOU GET THOSE. I NEED THAT

From the title i thought this was gonna be about HEAT shells (High Explosive Anti Tank)

2:49 HAHA, Rubber...

When the ribbon microphone?

Now make a collag cooling fan Air conditioner

Hey, your last vid (on chilling drinks) has comments disabled. I suspect this is a mistake somewhere as you did ask for comments in it. Just wanted to warn you in case you don't know.

Hawaiian people would love this

yesssssss

Where can I buy this multimeter?

Why didnt you buy a few of those heating elements and put heatsinks on them? Wouldn't that be a lot safer?

Bro you just made a lightbulb

I think that you might get away with using plastic instead of steel because the fan will cool the wires down.

I’m actually trying to do the same thing like you did but with a battery that I can also take anywhere with me it’s supposed to be like a little heater because we’re gonna be going on a camping trip and I need to be prepared so I’m building a backpack that is a little work bench and it’s actually going pretty good but the problem with it it needs a heater because when we go on a camping trip I will need to bring a tent and it’s gonna be really cold so I need to find a way to build a little heater box inside the backpack I do have a bunch of aluminum cans laying around in my room. I thought they were conductive but when I saw your video about using his legal with the special legal parts, and he said aluminum that reminds me of a aluminum can but I just need your help. Trying to find a way to find a battery that’s powerful nothing easy to charge so I can make a heater. I do have a radio that I can connect by using it as battery but I don’t wanna break it. I want to find a power source on an able to charge the radio while supplying power to the whole back that I’m creating so wish me luck.

new sub plus a complement i wish i looked like you

Nice

Советую вам приобрести тепловизор для более точного отслеживания температурных зон. Если совершить правильный выбор в приобретении, то вы не пожалеете.

electroboom of lego

I'm a pretty powerful Lego fan myself.

Can you make a electric motor with lego?

7:08 you make light

You just made a lightbulb

The house burner 9000

pfft cute

Unbelievable how he's just goofing around and accidentally makes something really useful

Any chance the apartment no longer smells like burnt fake lego? 😉 I hope your landlord isnt watching this video 😄

Wot is that word

E aqui no brasil um calor do carai😂😅

5 ohms is not a lot its alot only for a wire

This video was HOT, just unbelievably HOT.

Just use an overloaded laptop battery

ay

There is no comments on your previous video

Hi

You made a fan to heat things up? Why would you want something so weird and useless?

?

Let’s hope not

Eww metric....whats the real temperature?

Please get a pop filter for your microphone. Please.

Bro remade the lightbulb 💀

I swear burning Plastics toxic
