i got a CRT monitor from my work's recycling cage! i'd like to turn it into a helmet with a working led matrix display. not sure what LEDs to get though.. i want it to be low-resolution, so the LEDs can be diffused to the size of coins. maybe i should use a series of horizontal LED strips so i can see through the spaces between? maybe with cloudy plastic strips over the LED strips to diffuse them?
The LED matrix will be made of horizontal 60 LED/meter ws2812b strips. The pixels will be 16.67mm away, and the strips are 10mm wide, so I'll be able to see through up to 40% of the screen. I'll input commands using a mini keyboard strapped to my arm.
I'm using a Circuit Playground Express microcontroller because it's what I have on hand.
another issue: sometimes a data pin connection will stop working right due to poor electrical contact with my lazy strip connectors (i think?), garbling all the strips after it until i wiggle the connector a little. unfortunately, the poor connection sometimes results in violent strobing, so i need to prevent this so i don't give anyone a seizure.
so, i think i need to solder all the strips. this will take about 60 solder joints and i've never soldered before. i guess it's time to learn!
i found a foam setup that fits my head pretty well, but this plexiglass panel feels heavier than i was imagining. i think i'll have to add a counterweight in the back and endure some neck strain. next time i'll use something lighter, maybe thinner plexiglass or some other plastic sheet. i should still be able to wear it long enough to impress people
my CRT helmet is all wired up and wearable! i put a water bottle in the back as a counterweight. the visibility and one-way mirror effect are both pretty good.
still don't know what to wear with it. might just go with a boring grey outfit? i'll try at least making a necklace out of a Mini Gender Changer adapter. looking forward to impressing people with this
i replaced the plexiglass with a thinner pane made of polycarbonate! it's flexible, so i bent it to be convex so it fits the shell better and looks more realistic. it's also lighter than the plexiglass, so the helmet is way easier on my back now!
this video no longer reflects reality for two reasons: i have since cleaned my room, and accidentally broken my mirror
here's a showcase of some of the animations!
wow, i woke up to 100 notifications! you all really like my tv head
here's more info about it if you're interested https://rose.systems/tv_head/
@vivianrose this is cool as heck and I’m glad you posted this latest video, bc none of the older ones would load. Great job, and it seems like you learned a lot too!
@vivianrose okay, I've just come across this just now and these are INCREDIBLE, I've always wanted to do some form of display on my own CRT head! Great work!
I absolutely love the ones that are gravity/tilt controlled, those are subtle but they really work well :)
@Tama23 thank you!! i love how it turned out. i'm actually helping my friend Eleanor make one of her own so i'm hoping we can go out and impress people together before i graduate!
let me know if you make a display for yours and want some advice. the one for Eleanor is gonna innovate some features. We plan to align the strips diagonally to give her a denser resolution, and we got a bluetooth-capable microcontroller so she can control it from her phone (because she wants to type Chinese text)
@vivianrose ye i just saw, me really likey
I should make one too, I have an arduino laying around and finding a CRT shouldn't be hard
