hey lion, I'm wanting to do a environmental pack that has different sensors like temperature and stuff that's gets displayed somehow, would Arduino and these displays work for that project?? thanks for any help!

If at first you don't succeed, try a bigger gun!

Yes, of course. But if you need to use multiple displays, you'll need each of those to have different addresses to send stuff to the propper one. I have yet to try that. Also, memory on the Arduino is another critical factor. Each drawing you want to display consumes a lot.

Aliens Colonial Marine M41A pulse rifle SFX and light board.
One switch is for the trigger, and the other is for the inserted ammo box (that's why it need to be held down).
Althought not Star Wars related, learning how to work with LED's, segment displays and sound boards is always interesting for all blaster projects.

Been a while since I last posted. Honestly, I got bored of the whole "bondo, sanding, you didn't get to fix it, repeat" and quitted working on my helmet. So in the spare-time I got on my job, I been learning a bit of Arduino coding. The idea is to make an app that controls everything on my hypothetical helmet from one of my gauntlets.
For that I'm using Bluetooth serial communication (big battery eater I guess) between my Android phone and an Arduino IDE compatible board (ESP32).

I know there aren't canon references of interior helmet lights, but it's a nice exercise to practice and I think it's cool la Samus Aran helmet.
The app features a colour selector for the lights, brightness level and different animations (fixed colour, breathing effect and rainbow cycling).
The other feature is displaying videos, hardcoded testing, have yet to make it load them from a folder.

My ideas for the future:
-Servo rangefinder control.
-Setting up helmet fans.
-Controlling an OLED display like the ones I've posted before.
-Change everything to Bluetooth 4.0 (Bluetooth Low Energy/LE) for battery saving.

Glad to see you like them :)

With a bar like that you could do something like


[Green]
[Green]
[Green]
[Green]
[Yellow]
[Yellow]
[Yellow]
[Red]
[Red]


Then as you click the "trigger" every X clicks turns off a light (top to bottom) to simulate an energy pack depleting. Then with a secondary button (perhaps at the bottom of the stock) it refills as if reloaded.

This has been on my list of things to try, and I really should order some more LEDs.... hmm I think I know what my next project will be come payday
could use magnets that transfer the power and signal to removable magazines with LEDs to do the count down for like a blaster?

Sure, why not. Thing like this exists afterall:


Another (cheaper) option would be using magnets for positioning, but having normal contacts pressed against each other.

I want to share with you something that I made long ago but never remembered to post. If you like my stuff, I might consider doing comissions.

It's a gauntlet display for an U-Wing mando pilot.
There's a button to open/close the wings.
The display doesn't follow a fixed sequence, but uses randomly generated numbers instead.
Upper left simulates readings of the hyperdrive.
Upper-center is the ship designation (UT-60D) in mandalorian.
Mid-lef, the beskar diamond shows the shields level.
Bottom-left 2 "leds" show which side door is opened (this ship has repeating blasters on both sides).
Mid-right is for the overload of the cannons (designation KX7).

Periodically, the Arduino "rolls a die" to check if it's time to simulate a firefight. During combats, wings open (and sometimes doors) and Arduino keeps rolling dices to simulate impacts and lower the shields. Also the heating level on the KX7 cannons change independently.
After combat, shields regenerate and cannons cool down.

Hey! Would you be willing to sell the code, and any additional programming so I could buy the components and build my own?

I return a year later to the Android/Arduino project, covid got me some time to tinker. If you already saw the previous posts, you could skip the first demos.
What's new:
-Fan control. Concept works, final version will requiere some test & trials with hardware (fans, buck converters, etc).
-Servo control. 0, 90 and 180 degrees. Can control (not pictured) up to two servos, separately or at the same time.

Upcoming: Some servo parameter configuration, as each one is different.

Have  you ever thought "Ok, that chest display is nice but I don't want to buy one for each animation"?
Well I did, and that's why this project started a while ago, and these past days I had some time to work on it again.

Please excuse the potato quality. I'm working 12h shifts in another country and that leaves me a good amount of time to program. That's also the reason you don't see 7 segment displays, 'cause I didn't feel like packing too much electronic stuff into the airplane.

So, to summarize: It's an Arduino with a micro SD slot where you put a file with the animation sequence in a file called sequence.ini.
To help everyone customizing the sequence of their choice I also made a simple Windows program that lets you toggle on/off the different elements, generates the sequence and then exports it to the .ini file.

Next step is making it with real 7 segment displays, then designing the electronic boards and finally, production.

I also made some extra progress on the Arduino/Android app: Now I'm able to input servo's specs and define to which degrees the rear, up and front buttons will move the servos.

A quick onde-day build to learn how to use fonts with displays. It eats a great amount of an Arduino's memory, no wonder why MandoPuter uses more powerful boards.
A colored 1.15" display (pre-Beskar gauntlet) or 1.3" (Beskar gauntlet) would look better, but this was dirt cheap (under 20$).

And in other news, I finished designing the board for the customizable Fett Chest display and is now in production. Will post updates in a few weeks.
