    Re: Detecting A Bullet

    Tech is not usually the best answer for downrange systems. It's easy to damage anything on the far side of the trigger, so it's best to stick with Cheap/Easy.

    I do what you're talking about frequently, for 5.7x28 practice. I buy the electric yellow day-glow paper, stack it, and cut it to a size that will patch my targets' impact marks. Even a pellet gun hit shows up instantly on that stuff.

    Bonus: I save money by closing up my groups.

      I bought an Arduino configured audio sensor that lets you adjust the ambient sound threshold then anything that exceeds the ambient sound will trigger a pin at 5 volts. It works well and might suit the application. The only thing it won't be able to do is determine which target from multiple targets was actually hit, but that's not a big deal really since visual inspection will be enough in this application.

      I'll report back when I test it, but that might be a while.

        Yet another Samsung QLED Boot Loop
        by Takeatry
        Samsung QLED QN50Q — purchased 2022 started experiencing a delay in the picture coming on in the morning less than 2 years later. Did not know the term boot loop at that time. As the loop delay ran into a few minutes did all the recommended troubleshooting, soft and hard reset, changing cables and outlet locations, no help. As the delay increased contacted Samsung tech group and allow them remote access the tv. Tech was moving too fast to see exactly what he was doing but this ultimately it was also no help. Lived with the delay until it stretched out over 6 hours. Pulled of off the back cover...

        Samsung UE49MU6105K - boot loop, horizontal lines
        by blaster_
        Less than a year out of warranty, samsung UE49MU6105K craps out, they've got this designed obsolescence down to an exact science of self destruct when out of warranty...

        Screen started to show horizontal lines and ghosted image at the bottom, then turned off by itself. Did software update, to no avail of the line problem, and got a boot loop after some minutes of watching TV. This boot loop will turn on the backlights for some seconds the sound comes on, the image will turn dark very fast and then it reboots again. Pressing power button will not put it on standby. Disconnecting...

        Lenovo Legion 5 (15ITH6H) kind of boot loop but not sure
        by Stefano Crivellari
        Hi, I wonder if anyone can help me fix my Lenovo Legion 5 (15ITH6H) laptop. Basically, after a windows update the computer would not boot anymore. When powering on the laptop the screen has no backlight and nothing would show up, using an external monitor did not help. However, the laptop would still spin up the fans and turn on the keyboard backlight. The keyboard backlight intensity function key would work and the power button led and the charging led are also working. I've tried every possible combination of key press and power button hold down time but did not change anything. At this point...

        HP gaming 15-0013dx quanta G3HA no video, screen polarize on and off loop
        by ferah831208
        I have an HP gaming 15-0013dx laptop , motherboard quanta G3HA with AMD Ryzen 5 cpu and Nvidia discrete grsphics card. The laptop turns on and u can see the screen polarizing on and off in a loop but no video signal. All voltages are ok measured and stable (I checked all with oscilloscope). This schematics don't have power sequence but I'm using a similar sequence from another laptop with AMD CPU and I get all to the point CPU must release apu_pwrok and apu_rst#, this signal comes valid only for the period of time the screen is polarized and they disappear and same loop behaviour (active/inactive)....

        Samsung un82ru88000f - Boot loop sort of but can correct with taping of LVDS ribbon
        by NolesFan
        Hello all... TV started boot looping. Opened the back panel and tried to isolate the problem. Just PSB no boot loop. PSB and MB no boot loop. Plug in the LVDS from panel to MB and boot looping starts up. It doesnt matter of order that I plug the LVDS ribbons back in, only 1 and no boot loop but as soon as 2nd one plugs in boot looping. I then noticed a flicker on the screen when I was closing the clip on the harness to the LVDS. Shut the lights off so I can see better, and I noticed as i slowly close it, I will get a picture, but as soon as it clips in, I lose picture and booting happens. So I...
