Have you given any consideration to using things like WS2812B LED strips? Could then adjust the colour through the pulse and completely controllable via arduino.

If interested I shall share some work I did with them earlier in the year.

For this last idea, or in general terms? In any case, I didn't even think on them  so I'll read about it. Thanks!

EDIT: Ok, I've read a bit and they seem easy to use, will get some.

Just in general terms. They are really easy to use and would be perfect for the scrolling light.

I used them to create "stars" for a friend who was making a dress with a "stars" theme. We put them into the dress so they randomly lit up a random number of lights for a random amount of time behind the fabric. 300 LEDs being driven from a  Nano Arduino clone. Arduino is powered from a 9V battery and the two strings of LEDs from 2x USB power bricks

3D printed the Boba Fett rangefinder to continue working on the display. As you can see, it fits inside of what should be the perspex block. Will probably use a small Li-ion battery to power everything because 4 wires are a bit too much.

Finally received my strip of WS2812 LEDs for testing. They're cheap, apparently easy to use and offer tons of possibilities. Thanks for the suggestion!

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

Lion, I would love to know how you did the rangefinder display, do you have any info or tutorials on how it works? I know a bit about using arduino, but stuff like your rangefinder display is new to me.

How good are you at coding?

I use and OLED display (128x64 pixels resolution, I2C protocol) and an Arduino Pro Mini.

For programming, the Adafruit SSD1306 library (I think). Download, read examples and read how the library works internally. Then find some tutorials on your language. And read how to use LCAssistant. There are basically a bunch of commands to learn if you use Adafruit's library.

The thing is, Arduino's memory is really low. You'll need to be creative to  make everything fit and work.

Something like this you mean?  :P
Sorry for the aweful quality, was the only way I could get the camera to "see" the LEDs.

Exactly something like that :P
I actually ordered up my LED strip the other day after posting it to do this very endevour

That ammo counter is awesome! Exactly like something I hope to do. Want to customize sounds too and put in a blaster noise and reload charge.

Hi Lion!
I have the same 4 pin display and an arduino nano clone. Can you send me the code for the tramp please?

 :o

Im totally jealous about your skills. The Rangefinder LCD Display is totally awesome and give
your Kit a special detail, everybody is searching for.

If you gonna start to sale kind of this, give me a hint =)

IF I ever have a kit hahaha. I'm just too lazy for the path I chose (pepakura helmet).
In the last months I worked on a display that I'm very proud of, like 10 times better than the RangeFinder. Designed it for an MMCC member, hope we can finish it soon and show it to you all.
And it doesn't require that much of skill. Just knowing the basics of Arduino, hours in MS Paint drawing pixels (for real) and then transfer it to a more or less optimized program. The hardest part is to be creative enough to mix many different parts in one program (charts, bar graphs, drawings, etc) working at the same time.

I'd really like to have more time to sell/trade this for other cosplay pieces, but my job and main hobbies consume a ton of time.
