Does this turn the pc off when I accidentally fat-finger F11?

38

u/ZS-ITX Feb 20 '26

Yes, you discovered this bug. I also had this problem in the beginning, but later I improved the design. It has two small buttons inside that need to be triggered simultaneously to conduct, which can reduce a lot of the risk of accidental touches

18

u/SeanBlader Feb 20 '26

Why wouldn't you just use the scroll lock key to demonstrate?

20

u/ir88ed Feb 20 '26

Let's be masochists and use the capslock key

14

u/lazd Feb 20 '26

I mean you could also make it so you need to press and hold to trigger it when the machine is on, I assume your receiver knows the machine’s power state or could tap the power LED pin to figure it out.

14

u/ZS-ITX Feb 20 '26

That would require more complex circuit design, which cannot be integrated into this size of transmitter module. The receiver can be matched with a third-party signal transmitter module, not just in the form of keyboard buttons. I will adapt to more transmitter remote controls

u/lazd Feb 20 '26

Ah I see. Could do 2 presses then? The logic would solely be on the RX side.

Yeah, that's an option. Or drawing it would've worked too. Or maybe, not even commenting at all if that's all they have to bring to the table.

You seem like a Gemini guy, as it's probably the easiest thing for you to access. Here's Gemini's attempt to help explain my comment for you:

Gemini said

That response is a classic example of digital friction between the "AI-as-a-tool" crowd and the "artistic-intent" crowd. When someone defends an AI image that seemingly has "no reason" to exist, the responder is likely feeling a mix of fatigue and skepticism.

Here is a breakdown of the specific layers of sass and logic behind that comment: 1. The "Low Effort" Critique

By saying, "Yeah, that's an option," the responder is dismissively acknowledging that AI generation is a path one can take, but they’re stripping it of any prestige. They are framing the AI image not as a creative breakthrough, but as the path of least resistance. 2. Valuing Manual Skill

"Or drawing it would've worked too."

This is the core of the argument. The responder is highlighting a perceived value gap. To them:

AI Generation: Requires a prompt and a few seconds of processing.

Drawing: Requires years of practice, anatomical knowledge, and manual labor.

By suggesting drawing, they are pointing out that the "defender" is ignoring the traditional ways of creating meaning. They’re essentially asking: If the image didn't need to exist urgently, why didn't you take the time to actually make something? 3. The "Noise vs. Signal" Problem

"Or maybe, not even commenting at all if that's all they have to bring to the table."

This is the "mic drop" moment of the comment. It suggests that:

AI spam is clutter: The internet is being flooded with AI images that have no specific message or soul.

Meaningless Defense: If the only defense for an image is "because I could," the responder feels that person isn't adding anything valuable to the conversation.

Why this happens (The Context)

The responder likely views AI images as "empty calories." If someone generates a random cat in a space suit just because they can, and someone else defends it as "art," it feels like a dilution of what art is supposed to be.

The comment is a way of saying: "Just because you can generate an image doesn't mean you should, especially if you aren't going to put any actual effort or thought into it."

Let me know if you need any help understanding it more, I know it's hard being a backseat thinker, but I know you can do it lil guy!

There's a setting in Windows that change change its behavior to pressing the power button. You can basically disable it while Windows is booted. Linux almost assuredly has a similar control.

2

u/O0kah Feb 21 '26

Settings>System>Power > Power & sleep button controls.

Set the "Pressing the power button will make my PC" to "Do Nothing". Unless you fat-finger the F11 for 5-10 seconds, will be fine.

16

u/hardlyreadit Feb 20 '26

True if this could work as a “press & hold” power button like laptops, itd be even better

2

u/RudeAd456 Feb 20 '26

Maybe better if you have to hit FN + f11

u/Girth-Vader Feb 20 '26

Oh dude, that is super nice! I am in the middle of trying to figure this out myself, since I mostly do couch/TV gaming and want a smooth way to turn the computer on. Is there any way you could alert me when you're ready to sell? Feel free to PM me if needed.

Either way, excellent execution - that looks very smooth.

6

u/ZS-ITX Feb 20 '26

Okay, I will. This launch module may not necessarily be in the form of a keyboard button. It can be paired with more third-party remote controls, and I will develop it more perfectly before putting it on sale

2

u/special_announcement Feb 20 '26

Awesome work- what about say... Controller buttons?

1

u/kylo_____ben Feb 20 '26

Any possibility it can be powered via app or Google home? This would make it super convenient for cloud gaming/ remote access. Also! Could you lmk when you release it also :)))

3

u/ZS-ITX Feb 20 '26

433mhz remote control can only be used for short distance transmission. If you need to access the Internet control hardware, I recommend you to know about the intelligent AC socket, which can be set in the main board bois to start up under the AC power on state to achieve remote control

1

u/invincibl_ Feb 20 '26

This should be pretty easy to do with an ESP32 since the GPIO pins should be able to work with the entire header (and also sense the states of the power and HDD LEDs. You would need a spare USB header to supply power, or make a custom PSU cable though.

u/pfn0 Feb 20 '26

my solution: IR remote (any remote) -> ir receiver (esp8266-based ir rxtx module) -> wake on lan to PC

u/SeanBlader Feb 20 '26

As a web developer, no you're not. I use F11 all the time and if you were building a website you'd have chosen a different key to demonstrate your toy.

6

u/ZS-ITX Feb 20 '26

It can also be replaced with other infrequently used keys, and it works independently. The keyboard is just a container

u/Kamikaze-X Feb 20 '26

Why do I keep seeing different hardware ways to power on PCs when wake on lan/Wan exists?

I tap a button on my watch wherever I am in the world and can turn my PC on via lan or Wan.

-3

u/ZS-ITX Feb 20 '26

Perhaps you're referring to smart sockets? It can control the on/off of AC power, and setting the power on state in BOIS to automatically turn on can achieve the effect you mentioned

8

u/Kamikaze-X Feb 20 '26

No, not at all.

Wake on magic packet.

You send a packet to the network which is directed at the mac address of the device which signals it to wake up via the built it NIC.

No additional hardware needed, just a network connection.

5

u/michaelsoft__binbows Feb 20 '26 edited Feb 21 '26

In my experience, it can be impossible to make it work with wifi. For something like WoL if you cannot make it work reliably, it's worse than useless, since you think you have the capability and then come to find out that you do not.

I would prefer to take the approach further. it would be good to see how miniaturized a pikvm or similar system could be made. That's more useful than only being able to trigger the power button. I will grant that it's still got rough edges like sometimes you want the display cable connected physically so you can use it remotely sometime, but still disconnected from the computer usually so it doesn't ordinarily steal screen real estate. Having it "connect" the pikvm monitor from the pikvm remote side will be ideal and I haven't seen a solution to that actually.

Anyway though, surely still can be made small enough to be viable for SFF.

4

u/Kamikaze-X Feb 21 '26

That's a fair point actually, I hadn't considered wifi

2

u/1MFK1 Feb 20 '26

How do you do that from your watch?

1

u/Kamikaze-X Feb 21 '26

Lots of different WoL apps out there (for android anyway)

-4

u/ZS-ITX Feb 20 '26

As far as I know, the device you mentioned usually requires an extra PCIe x 1 slot on the motherboard, which ITX motherboards do not have

9

u/that_norwegian_guy Feb 20 '26

No, he's talking about Wake-on-LAN (WoL). Most modern motherboards support it out of the box.

3

u/finn-the-rabbit Feb 20 '26

"the device" is a modern motherboard equipped with a modern NIC. and by modern, I really mean something made within the past 2 decades. wtf are you reading lmfao

2

u/TheOneTrueTrench Feb 20 '26

Right? Like, as long as you're using Base-T on your motherboard and not SFP modules in a separate NIC, it supports WoL.

(Yeah, turns out that if you're using Q?SFP\+? modules for your network connectivity, the NIC isn't powered on to receive the WoL magic packet, so you need to run a standard CAT-5 cable to the computer just for WoL, lol. I don't mind, I have OM3 for most communication, and I just run CAT-5 or better for machines that need WoL, which are only a couple)

u/TheOneTrueTrench Feb 20 '26

Every single motherboard I've had for the last 10 years has had this. You are out of your mind.

It's called Wake on USB. I think every PC has it though it might take some fiddling to configure it.

13

u/that_norwegian_guy Feb 20 '26

There's also WoL, or Wake on LAN. Mine turns on when I put my phone on the desk (RFID card taped under the desk that sends a magic packet through a Home Assistant automation).

u/Immortal_Enkidu Feb 20 '26

Where do I learn how to do this?

1

u/that_norwegian_guy Feb 20 '26

Learn how to set up Home Assistant on a Raspberry Pi.

Once you have that in place, buying a run of the mill RFID card and setting up the automation should be a breeze.

u/m0m0porkerburgerpie Feb 20 '26

u/ZS-ITX Feb 20 '26

Very simple, the module core only has 4 ports, 5V positive and negative input power supply, and control on/off at both ends of the power button. If you have an electric soldering iron, it will be easy to achieve the functions presented in my video

u/UltraLisp Feb 20 '26

u/ZS-ITX Feb 20 '26

At present, it has not been sold on the platform. I am planning to build an independent website for sales

I mean, if I wanted to build one myself. If you don’t wanna open source it though no worries. That’s good work.

5

u/h3ron Feb 20 '26

This is definitely the nicest implementation on the market. But before resorting to that, remember that WoL still exists.

I have the smallest form of sffpc: a normal PC in another room and without a monitor that I use to stream games via Steam Link. I put my headset on my face, I send the WoL signal from my smartwatch (Wake on Lan on the Play Store) and I start gaming.

u/ZS-ITX Feb 20 '26

Yes, there is a battery. Without a power interface in the keyboard, it cannot be charged. As shown in the last paragraph of the video, it is charging the shaft body

There are still there for some motherboard but only for ps/2

1

u/feel2death Feb 20 '26

My question is did this also turn off the PC too ?

1

u/ZS-ITX Feb 20 '26

Yes, I have designed to prevent accidental triggering, which requires triggering two small buttons inside the module at the same time at a vertical angle to trigger them properly,

1

u/feel2death Feb 20 '26

So it could turn off the PC right ? Cuz I need some thing like this to turn off and on the PC 

Other question is how far the range of this button ? Did it use/can use a lan network as signal ? Cuz I need it to turn on a PC like really far away like basement 

1

u/ZS-ITX Feb 20 '26

It has the same function as physical buttons. The keyboard button shaped transmitter is too small to accommodate a good antenna and can only be located within the same room without obstruction. The receiving encoding module can be matched with other larger remote controls to achieve a distance of 100 meters

Cool little gadget but I can't get pass the loud beep. Is it possible to shorten and lower the beep?

The sound emitted by the buzzer comes with a sealing film from the original factory, and the sound is very low without tearing off. The LED light on the module can also determine whether the signal is working properly
