Lichtknarre: Unmodified Wii remote as a sight accurate Lightgun using 2/4 LEDs

I was kind of hoping we could get it to a point to where off the shelf leds could be used without much fuss. Right now, with these dead led stories it sounds like they are still fussy.

Mamehooker already supports wiimotes. Depending upon his communication method they can potentially work independently of each other without interference. It's a generic HID write if I remember correctly.

Buying them from Amazon (provided they are also shipped from Amazon) is about as "off the shelf" as it gets nowadays :) Don't let the LED comments spook you. It's just the typical Chinese goods saga where shoddy QC is the order of the day. You can use any IR LEDs you want to, if these give you the jitters. You can even take the Nintendo route and use little clusters with a lower performance LED and just point them in slightly different directions from one another. These were just a good selection because they are relatively cheap, powerful, have wide viewing angles (which seem to match the datasheet) and are in a small and attractive case. They also need only a simple wire connection, with no PCB or heatsink if used properly. There are others which are similar, but more money, and which may also have better QC...or they could be exactly the same and you just end up paying more. It's always a crap shoot with Chinese stuff, but it's not like there's much of a choice :)

If you don't like soldering, you could probably also just buy a pre-made IR LED set with wires intended for a different light gun, so long as the wires are long enough for the screen size and the layout required. It seems like the same camera module is used in those other guns, so if it works for them, it will work for the Wii remote.

You are probably correct about Mamehooker just working with the remotes. As long as there's no low-level shenanigans, an HID device should just act on commands from whatever is talking to it. It deserves a try if you already have something which works to identify the active process and relays recoil or rumble information. It'll probably just work.

BadMouth:
I was wondering when Howard would show up. ;D

$3 with heatsink from AliExpress, but you only get one spare: https://www.aliexpress.us/item/2255800909434686.html?gatewayAdapt=glo2usa&_randl_shipto=US
Step down voltage and current regulator like the one I'm using can be had for about the same price. Long wait for shipping, but add some 18 gauge wire and a random wall wart and you can play along.
(assuming you already have a wii controller and bluetooth)

There is an official setup on the Lichtnarre website which uses heatsinks and separate lenses, but I wanted something smaller and cheaper.
I thought about using those heatsinks and cutting one side off to get the LED closer to the screen, but have too many other things going on at the moment.
I am happy with the way mine are set up now, but haven't had time to finish setting up the guns or put many hours on the LEDs.

Howard_Casto:
I'll throw a couple batches of those leds in my cart, thanks. In regard to positioning the leds, couldn't we do that with a simple graphics displayed on the screen with guide lines? I'm sorry I arrived late on this one, but I have several questions.....

Can the leds be powered via USB or do they draw too much current?

What's a good bluetooth adapter to use? The last one I bought came over on the mayflower so my data on the subject is probably outdated at this point.

What about lenses? You mentioned the wide-angle lens but I'm wondering how we can improve upon that. I have a 3d printer, so if we can find a reliable, readily available and inexpensive lens with something to attach with (like some threads) I would be willing to work on adapters. It seems like one for the standard wiimote, one for the zapper, one for the sega gun shell and one for the capcom gun shell would do it.

I remember at some point a third party was working on wireless nunchucks that piggybacked the I2C data stream and used it to inject their own data. Did anything become of that? I reason I ask is instead of hacking up wiimotes to add solenoids/ect. maybe we could hook a avr to the I2c port and read the led and rumble data and control solenoids/motors/ect. that way. I'm not sure what the best route is in regard to that, but I'm just throwing ideas out there.

Hate to be "that guy" but you should probably take a few minutes to read the thread from the beginning. There's a lot of "back and forth" there, but also the answers to most of your questions, as well as a little app I wrote which seems to work in helping to position LEDs. I've used it twice so far and haven't had any position issues. YMMV :)
