I have the ASUS PN50 and I'm just wondering if anyone here knows how to set up the IR on this thing. I have all the W10 drivers installed (Human Interface devices - ITECIR and Microsoft Home Infrared Transceiver), I have tried Eventghost and all its plugins, but nothing seems to work. Please help!

I have a Logitech Harmony Hub and would like to turn on my PC using either Bluetooth (preferred) or IR. Is that possible? Does anyone know how to get it working? In the past, I think I could wake from 100% off, but I might need to go into standby or hibernate to do it with Win11. I've setup my PC to connect to the Harmony Hub using Bluetooth: Logitech Harmony is installed and has my PC setup as a device. I can even control Windows using the remote over Bluetooth: I also have one of these old Philips OVU4003/00 IR Transmitter device that I used to use to turn on my PC with Harmony about 10 years ago. I haven't had it setup for a while though. It shows up as an eHome Infrared Receiver (USBCIR) device: My motherboard is an X570 ITX board from ASRock configured for UEFI. Is it possible to turn on my PC using either Bluetooth or IR with Harmony?

I thought this post might be worth making because I've seen a lot of hardware reviewers using thermal (i.e. IR) cameras to check external temperatures (most recently in the "Backplates cool your videocard" LTT video, but I've seen a lot of other websites do it as well). I want to make it clear that I'm not writing this post to attack LTT or anybody else, but instead I'm doing it to offer a bit of knowledge to the handful of people out there who might actually be interested. So rather than doing real work, I'm going to give a mini IR camera physics lesson on an internet forum instead. IR cameras don't have a way of directly measuring the temperature of objects in the way that a thermometer does. Instead, they measure the amount of thermal radiation coming from a surface (IR wavelengths in this case), and then use that intensity to calculate a temperature using what's known as the Stefan-Boltzmann Law. The equation looks like this: T = (I/(e*A*s))1/4 where T is the temperature, I is the intensity of the IR radiation entering the camera, e is the emissivity of the surface you're pointing the camera at, A is the area of that surface, and s is just a constant which we can ignore here. The important thing to note here is that there are other variables which go into this calculation, namely e and A. Now, the most important one, and the one I'm going to focus on is the emissivity e. Emissivity is a property which varies from one material to another, and is essentially a measure of how well a given material behaves like an ideal black body (i.e., how good the material is at radiating IR). It can range from 0 to 1, where 1 is the equivalent of an ideal black body, and 0 means that the object doesn't radiate any IR radiation at all. Most thermal cameras (including the FLIR ones that I think most tech reviewers use) assume that the emissivity is 0.9 or so. This means that if the object you're pointing the camera at actually has an emissivity of 0.9, then the temperature that the camera shows on-screen will be accurate. However, there are plenty of materials which do NOT have an emissivity of around 0.9. Metals would be the most relevant example. Metals tend to have very low emissivities (often less than 0.1). So what happens if we try to measure the temperature of, say, a copper surface with our camera? The emissivity of copper is around 0.05 (varies a bit depending on smoothness of the surface), but our camera is assuming that the emissivity is 0.9, which is WAY too high. This means that the temperature that the camera calculates will be considerably lower than the true temperature (see the equation above). Metals have another problem, and that is that they are also good at reflecting IR wavelengths. This means that when you point your camera at that piece of copper, some of the IR radiation that it's measuring is actually coming from somewhere else in the room and simply reflecting off of the copper surface and into the camera. These two different phenomena combine to make it look like the piece of copper is colder than its surroundings, when in reality everything is the same temperature. This is exactly what happened in the IR images shown in LTT’s “Backplates cool your videocard” video. In the images it looks like the copper region is much colder than the surrounding backplate, when in reality it was probably as hot or hotter. So there are a few conclusions that we can make here. First, one should take a grain of salt if exact temperatures are measured using a thermal camera. If the emissivity that the camera assumes is different than the emissivity of the object you’re measuring, then the temperature given by the camera will be incorrect. Second, we CAN compare relative temperatures between different regions, if we do it carefully. This can be done by putting a piece of non-shiny tape on each of the surfaces that you’re trying to compare. The tape will equalize to the same temperature of whatever it’s attached to, and because you have the same tape on both surfaces (e.g., a piece of copper and a piece of plastic), the emissivities will also be the same (because now it's the tape radiating in both cases) and the temperatures of the two objects will be directly comparable. You can even take this a step further if you want to get accurate temperatures. If your camera allows you to manually set the emissivity of what you’re looking at (many FLIR cameras do), you can determine the emissivity of the tape you’re using by putting some tape on a surface, measuring its temperature with a normal thermometer, and then adjusting the emissivity in the camera’s settings until the onscreen temperature matches the true temperature. Once you know the emissivity of your tape, you can then use that emissivity in your camera’s settings to accurately measure the temperature of anything that you put the tape on in the future.

Hi, I want to use my old Samsung Galaxy Note 10.1 as my Spotify control device. So I thought to myself, is there any way that the IR blaster could receive data from an IR remote (an ODROID one)? Best regards Ondřej Pekárek

OK, so i have this great idea for a way to control my room. I have a harry potter remote control wand (Link at the bottom) and i want to try and use it to control my philips hue lights. My idea is beucase the wand works with IR i point the wand at the Logitech harmony hub and it blasts out a singal to the philips hue bridge and thus my lights turn on. Is this a crazy idea or would it work Harry Potter Wand (https://www.amazon.com/dp/B00FXMDRZK/ref=asc_df_B00FXMDRZK5193336/?tag=hyprod-20&creative=395033&creativeASIN=B00FXMDRZK&linkCode=df0&hvadid=194024095585&hvpos=1o1&hvnetw=g&hvrand=5782725677349068604&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9012089&hvtargid=pla-314762759648)

Having issues with my Arduino Uno. I am trying to hook up a 2pin ir led and receiver and have them actually work. Any ideas?

So I am currently setting up a DIY home security system, I have a phone in the lounge room and I want it to have night vision. I have a LOT of questions -what happens if you don’t take out the ir filter in the phones camera -if you do take it out, will videos look the same during the day or washed -what is the difference in the night vision between the filter being in or taken out -how many ir leds will you need to light up a room full of inferred about 15m from the camera -does shining ir light onto objects during the day affect the look of videos in the day (washed, normal, blurry) -is there a way to get around ir light bouncing of glass -are other cameras going to be affected at day or night? -how do you know if your phone has a ir filter in the first place? Thank you for any help

Hi all, I have a NAD T753 (I know, kinda old), and IR control no longer works. I know the remote works fine, since I still use it for controlling my TV and Xbox. I know the back of the NAD system has an "IR in" port, so here are my questions. Would just plugging in a new receiver (something like this) maybe fix the problem? Does just plugging that in have a chance at solving my problem? If so, are all receivers created equal? Does this remote operate on a different frequency and I have to get a special receiver? I'm not very well versed in this, so any help would be greatly appreciated. Thanks!

Hi, Just got the Android 8.0 update on my Sony KDL55W800C and wanting to utilize the new voice control feature similar to the Nvidia Shield. Would buying a newer Sony IR remote RM-FTX300A be backwards compatible and work? Cheers.

So going to run HDMI in the wall to get a Tivo where cable boxes cannot go. I know this is made but I can't find it on Amazon. What would happen is when in the other room I press a button on the remote. Then it sends it to a sender and sends the IR and then the remote work. Where can I find this?

Hello, I just kind of finished my watercooled pc build and want to know which rgb remote controlled led strips are most popular and reliable(also cheap). And please add links for europe Thanks!

I have a Logitech Harmony 600 and was wondering where could find a receiver to use this with my pc? I mean I have a K 400 wireless keyboard I us on occasion to pause movies and stuff but is there internal IR receivers or usb? I know sounds kind of dumb me not knowing but I hadn't ventured into the home theater/ media center arena. But sense I've started using the keyboard for ps3 it made me wonder about pc and my remote.

I play a lot of Arma and have decided to get myself a trackir. I was all ready to make my purchase on naturalpoint's website until I got to the shipping method and these were my choices: 60$ for shipping a what 2 pound product?!?! Why air mail anyways... I have tried extreme gaming devices website (Canadian approved dealer or whatever) but they are charging almost 200$ for the trackir + pro clip and you have to phone to inquire about it or whatever... Anyone who has one of these that lives in canada / out of states did you pay so much for shipping? Is there a better location to buy? I want one of these buy I can't bring myself to pay over 25% to shipping costs on such a small product. Thanks for your help
