--- Quote from: RandyT on November 04, 2022, 11:56:53 am ---I'm seeing an oddity, possibly related to the angle compensation code. If I pan the screen quickly and repeatedly to the left and right , I see the blob pattern in the preview window tilting clockwise when moving left and counter-clockwise when moving to the right, even though I am being very careful not to tilt the gun. This incorrectly perceived tilt by the software seems to trigger the tilt compensation, which then gets confused and seems to place the cursor randomly on the screen as the motion continues and the software seems to become more confused. The interesting thing is that this does not occur when doing the same thing slowly. As long as I don't exceed a certain, somewhat slow speed, the pattern stays dead straight and the cursor stays where it should. I do not expect that this is linked to Bluetooth or system speed issues, as I can crank up the inputs per second cutoff to 120, which makes the cursor move extremely smoothly, but with no change in this odd behavior. I should also note that distance does not seem to make a difference. Fusselkroete, is it possible to add an option to disable the tilt compensation code entirely? While this may not be the root cause of the issue, it seems like the lower speed at which it operates causes error to compound, leading to the cursor ending up momentarily in places it shouldn't. --- End quote --- Yes it has an adjust time for 0.6-1s when tilting for the 4 LED Tracker-Plugin. No one realy had a problem with it and it was documented on the instructable website. https://www.instructables.com/Wii-Remote-As-Lightgun-With-Iron-Sight-Accuracy/ << Look Features :D The inputs per seconds has nothing todo with the position recognition code at all. Inputs per second cutoff is only the option how much the connector plugin sends data in a second to the apis/vjoy or something else. Look here : https://geekonarium.de/en/lightgun-lichtknarre-about-the-plugin-system/ Its also labeled, that this dialog is a connector plugin configuration for the vjoy or mouse connector plugin. So you can say it always recognize with the most speed as possible. --- Quote from: RandyT on November 04, 2022, 11:56:53 am ---I'm also seeing an occasional, but also rare, minor offsetting of the cursor. Usually, just going off the edge of the screen and coming back will correct it, or it will sometimes just manage to fix itself. No idea as to what might be causing this one. It almost feels as if the cursor ends up "stuck" in a small offset and then eventually frees itself. --- End quote --- This sounds like a reflection problem or some sort. :O maybe play around with the IR sensitivity setting. --- Quote from: RandyT on November 04, 2022, 11:56:53 am ---And as long as I'm asking for stuff, I'd also like to see a troubleshooting feature added. Namely, a basic, full-screen preview. It would be handy for larger screens to be able to double-click the preview window to bring it to full-screen so it's easier to see what is happening at longer distances from the screen. The code seems already to be present for this, so I wouldn't expect that it would be too difficult to add and it would be a nice feature. --- End quote --- There is a troubleshooting guide on the website. read this first please. https://geekonarium.de/en/lichtknarre-lightgun-wii-4-led-tracker-plugin/#troubleshooting --- Quote from: RandyT on November 04, 2022, 11:56:53 am ---One final oddity I found. In the 3. Default Gun calibration mode, I was only able to shoot one of the blue squares. It would progress to the next screen, but it would no longer register a button press to proceed. If I used the mouse to exit the mode, the trigger would again function normally. This seems like a bug, unless I am doing something wrong here. I did as the screen stated, having only two of the proper color dots on the screen, but could not get past the screen no matter what I did. The 2. default LED-calibration was no problem at all. --- End quote --- Why you want to shoot the blue squares? Do you speak about 4 LED Tracker or 2 LED Tracker? In the calibration mode you should put the IRs cycles in the squares. But i think they are green. And the describtion explains that on the same screen. Maybe thats why your cursor jumps from time to time without tilting or screen reflections. --- Quote from: RandyT on November 04, 2022, 11:56:53 am ---Edit: Whoops, forgot one. I also noticed that through some currently unknown combination of events, the blue dots in the preview window disappear, and only re-appear when less than 4 are present. Whenever there should be 4 dots displayed, it shows only the numbers and no dots. A re-boot of the software will fix this temporarily, so it appears to be a bug of some sort. --- End quote --- Hmm can you make a video of this please? When the software has no focus than there should be no update in the preview. |

For the record, I've read everything on the website like 10 times :) --- Quote from: Fusselkroete on November 04, 2022, 03:06:05 pm ---So you can say it always recognize with the most speed as possible. --- End quote --- Ok, that's good to know. I took this to mean the speed in which it was polling the Wii controller over Bluetooth. In any event, it doesn't seem to be the cause of the issue I am seeing. --- Quote ---This sounds like a reflection problem or some sort. :O maybe play around with the IR sensitivity setting. --- End quote --- That was my first thought as well. However, I would expect reflections to manifest themselves as a constant, as they would always be present. This doesn't behave that way. Most of the time, the cursor is where it should be. Only occasionally do I see this offset and it eventually goes away. IR sensitivity settings do not seem to affect more than the distance at which I can see the blob pattern in the preview with no flickering. That's why I requested a full-screen mode for the preview window for testing purposes. It's difficult to see what information the program is acting upon in that small window when you are 3 meters from the screen :). --- Quote ---There is a troubleshooting guide on the website. read this first please. https://geekonarium.de/en/lichtknarre-lightgun-wii-4-led-tracker-plugin/#troubleshooting --- End quote --- I've read it a few times. Nothing on there explains tilting of the blob pattern when moving laterally at fast speeds :). As I stated, if I slow down movements, everything tracks nearly perfectly without the software thinking the gun is tilting. But past a certain speed of movement, it does it nearly every time. Even with all 4 LEDs visible and being tracked by the camera. --- Quote ---Why you want to shoot the blue squares? Do you speak about 4 LED Tracker or 2 LED Tracker?

I should have written: "One final oddity I found. In the Default Offset Calibration Wizard, I was only able to shoot one of the blue squares. It would progress to the next screen, but it would no longer register a button press to proceed. If I used the mouse to exit the mode, the trigger would again function normally. This seems like a bug, unless I am doing something wrong here. I did as the screen stated, having only two of the proper color dots on the screen, but could not get past the screen no matter what I did. The 3. default gun-calibration was no problem at all." That doesn't mean I'm not doing something wrong. Just trying to follow the instructions as written on the screen. However, in this case, it instructs to shoot the blue dot, and there are "blue dots" moving all over the screen. :lol But, there is a small blue square, so I assume it means that one. If I shoot at that square, it gives me an offset of about -1.6% and then moves the square to the right. At this point, the program stops accepting button input from the controller and it does this every time, no exceptions. The only way to proceed at this point is to use the mouse to click on the "close" button, aborting the wizard. --- Quote ---When the software has no focus than there should be no update in the preview. --- End quote --- It does it regardless of program focus. Also, I usually have the box checked for showing the preview even when the program does not have focus. |

I've always thought P=VI, which in this case comes out to 1.26w = 1.8v x 700ma, --- End quote --- sorry, i misunderstood... that led is in a package typically used for 3 watt LED's... luminal power output =/= actual power consumption https://www.pcboard.ca/3-watt-led-bead-infrared |

The 3 watts comes from the maximum amount of power the package can dissipate before damage begins to occur. Regardless, these ratings are hard to decipher. Even at the link you provided, the same "3-watt" package shows a red LED producing 80-90 lumens (the measure of visible output) while the white version of the same LED puts out 140-150 lumens. The catch with IR is humans can't see it, and because those ratings are weighted based on the sensitivity of the human eye to those wavelengths , I assume they fall back to the amount of power actually being used to emit photons at those wavelengths (as opposed to heat). If that's the case, the IR version are only using a little over 1/10th of that 3-watt rating for IR light. But I'm not an LED pro, so I could be wrong about that last part :) |

Fusselkroete, don't let the criticisms cover up how grateful we are for this program. I bought these guns a decade ago to add to my arcade cabinet. Finally they are accurate enough to use them. Thank you. :notworthy: |
