We built a GIANT Bat Signal that actually WORKS!

Our bat signal has come A LONG way since my first laser based one in 2016! Check it out! https://youtu.be/5z7AkWxCtoc

To people that just look at the batsignal from the outside it might seem kinda lame, since they think all you did was use some big light and put a shape in front of it but we underdtand the work that went into this and how difficult it is to create what you have, amazing job.

The fact that the kid understood how the liquid cooling system worked completely blew my mind

Imagine what people just chilling outside felt when they saw an actual Batman symbol in the sky

20:44 the thing on the phone screen🥶🥶

It's nice to see a group of people working on a project that we don't typically see.

I suspect you are not getting a crisp image because of doubling up the lens. Your large lens seems to have too long of a focal length for the tube length, hence the leds being in focus rather than the image. Get that same size lens with half the focal length and you won't need the two part lens messiness. An internal aperture can increase sharpness further if needed. It also doesn't help that your light source is so far from a point. Put it further back and it will work better. I would recommend a commercial led stadium light rather than diy. You can get a 250k lumen stadium light for around $1,200 which is what I would use if I made another one myself.

The efforts you guys are giving for your projects is just awesome

If you do a future version, maybe have an adjustable structure to extend and retract the bat symbol immediately without needing to remove each time,

I feel like you guy can teach anyone technology-related science. As well as inspire someone to break the boundaries between fiction and reality on a grand scale. Hats off to you guys.

After seeing the real life batsignal, I can say that nolan's batsignal was pretty accurate and looks real

20:30 a german video???

As a former lighting guy for events this is quite common using a “LEKO” or source four fixture using GOBOs, metal or glass images. For best results you need a flat surface perpendicular to the light source. Nice project though!👍🏽💪🏽

Wow, that kid is super smart! I'm sure he has an amazing future ahead of him, he would be a great engineer for sure!

Making bat signals is all fun and games until Batman shows up and demands to know why you're wasting his time

28:19 the kid is impressive 😅😅

This guy can make anything from "movie magic " to real life like that's crazy

Dude that light refraction explanation while showing us the actuall light travelling using smoke is definitely better than any illustrations you can see in science text book

I love how much fun everyone was having with this project and each other, the Hacksmith just seems like such an awesome place to make dreams a reality

12:25 i like the joker just creeping in the background
