We've tried PID so far and a really basic one so far. As far as I know PID should be stable but we failed.
Our PID algorythm brought the robot to the finish but it was really unstable. Most of the time the entire robot wasn't even above the line. It was a big mess.
Our basic algorythm worked fine, it was more stable than the PID, but not reliable enough
I have a sharp TV hooked up to a wi-fi IR sensor linked with my google home. Now, it won't obey the command to turn up the volume. Mute, on, off etc work, but volume commands make the Nest speaker increase. It's so fucking annoying as I got this just last month and it was working great.
Are their any work arounds? Would Alexa still work?

Wondering if anyone has had a similar problem with the IR sensor. I have the MK3S+, kit version, built it early August 2021. IR sensor has worked from day 1.
A couple of weeks ago I noticed the sensor stopped working. Took everything apart per Prusa support site, fired it up and the sensor works again. I load the filament and after that it goes back to N/A sensor not available, check connection.
So I took it apart 2 more times, same results. I did check to see if the sensor was responding to any filament being inserted. 2 weeks ago yes, value changed to 1. Today no response, value stays at 0 through all the troubleshooting.
Tonight I spent 2 1/2 hours trying to troubleshoot with Prusa chat. We have checked connections restarted, put filament IN the sensor, and now the agent wants me to check with a multimeter. I don't own one and don't want one. So we hit a wall. I feel like all the steps we took make it pretty clear it's the sensor. But the rep said I had to get a multimeter.
I feel like it's pretty clear the sensor has failed. Nothing else has changed or stopped functioning. The sensor just started failing over time.
Any similar experiences?
I know that there's great variability between models but any data points would be interesting. I'm interested in how much the electronics of missiles, aircraft, ships, AA cost on a unit basis.
I've heard of the F-35's AESA or IRST systems costing about 2-3M$ which surprises me as that would represent merely 2% of the aircraft's cost while being one of its main assets. I'm especially curious to know how much an AWACS radar costs.
Does the processing computer aboard the platform tend to cost more than the sensor?
I noticed that the IR sensor runs constantly on this lenovo laptop I bought. Even after going to Lenovo Vantage and turning off human presence detection, etc. I can still see the IR sensor running constantly. (From my phone camera)
How do I disable it? Please help.
I was wondering if i could use a IR Sensor to detect black on a ipad screen? I know you can use it on black surfaces and what not i just didint know if it would work the same on a digital color.
Thank you!
Hi guys, I have a Lenovo laptop which comes with an IR camera/sensor for windows hello and other features like human presence detection.
I have disabled the human presence feature, disabled the IR camera from settings and haven't setup windows hello on it. It's weird that the IR light is constantly blinking even when using the web or reading a PDF, etc. In short, it's constantly running even when there is no reason for IR to work.
Is this a normal thing on all windows laptops?
PS: I didn't find much help on the Lenovo sub so thought someone from this sub can help me.
It would be really helpful even if someone who uses a different OEM laptop (with IR sensor) can point a camera and check if IR is being emitted on your laptop when browsing or reading PDFs?
The LED on the sensor turns on registering the ball but the input seems to go unrecognized. Any pointers?

I play wt on pc using my console account and at top tier i struggle because i cant use the ir sensor in top tier jets as in there are no options for it at all i only have switch radar/irst but no slave to ir or ir sensor toggle button at all, maybe i missed it but its a handicap i dont like having at top tier air rb
TV is a Sharp Aquos LC-46LE840UN. The problem I specifically want to solve is the aspect ratio, it's locked in stretch and we have to use a remote because the buttons on the TV won't actually change the setting. We ordered a new remote, used new batteries and when I checked the remote with my phone camera, it's working. I took the back off the TV and cleaned the sensor with an air duster, isopropyl alcohol and a microfiber cloth, still no response.
Is there any conceivable workaround to fixing the aspect ratio without getting the IR Sensor replaced?
