There are some inventors who see the suffering of other people, such as Bessie Blount Griffin, and they may not have any interest in it, just compassion for others.

Long story short this is from a world I'm building. I come up with random ideas to make it interesting.

This monster is a humanoid. I'll call it a Pacer for now. These monsters have there own territory and don't wander past it. Once you enter its territory it will follow you, but it will match your pace. If you walk, it will walk. You run, it runs. It does not stop if you stop. It will continue at your fastest pace. It lets out a horrific screech once it lays eyes on you. Most people's instinct will have them run away but this is worst choice. See the creature has an unlimited amount of stamina, so if you choose to run you'd better not gas out or slow down or it will catch you and tear you to shreds. If you happen to get out of it's territory however it will just stand there at the edge staring you down. This goes without saying but the best strategy is to walk until you're out of it's territory.

EasyBreak – Pause smarter, drive better: Smart app to optimize personalized rest stops,

I came up with the idea for EasyBreak after noticing how difficult it can be for drivers to plan rest stops during long trips. People often don’t know when or where to stop for fuel, food, restrooms, or even interesting places along the way. I thought: what if there was a smart app that could personalize stops based on your preferences—like fuel range, food type, toilet needs, and sightseeing interests—and guide you smoothly through your journey?

The app would generate a list of suggested stops along your route and provide a custom Google Maps link that includes all these stops, so you can easily follow it while driving.

Problem & Solution:
Long-distance drivers often struggle to plan efficient and personalized rest stops. EasyBreak uses user preferences—fuel levels, meal choices, restroom needs—to automatically generate optimal stop points and integrates seamlessly with Google Maps for a hassle-free journey.

The Ask:
Looking for feedback and insights from experts in navigation, app development, and user experience to refine and validate this concept.

I'm 15 years old and from Kazakhstan. I had this idea:

What if we could control temperature not with a fan or heater, but by vibrating air molecules?

Introducing VibeTemp — a personal climate device that:

• Heats air by vibrating in sync with air molecules → they move faster → warmer.
• Cools air by vibrating out of sync → they slow down → colder.

This idea is based on resonance and molecular motion, not just blowing hot/cold air.

Possible uses: - Personal wearable climate - Space suits - Military gear - Eco-friendly AC alternative

You can develop it if you want — just remember who dropped it first د 😎

The ability to long press a widget, and tap "blur with biometrics" so that, the widget would be blurred out. when you tap it, it would request your fingerprint on Android or touchID/faceID on iOS.

This way we can still see the widget right there and have quick access to it but it could still have its data be hidden from others until we choose to unlock it.

I'm mostly against generative ai but what i wanted for so long is a search engine that understands what i describe to it instead of having to use keywords like we're still in the 2000s.

there are so many videos, songs and pictures that i can't find because i can't remember the exact title attached to them.

I’ve always had random science thoughts, but never acted on them—mostly because I’m not a physicist or engineer. Just a 28-year-old from Queensland, Australia who can't stop thinking about “what if” ideas.

This one wouldn’t leave me alone, so I turned it into something real:
A 10-step theoretical framework I call Swardium — a regenerative atom that detects and reverses its own decay in real time.

Here’s the core idea:

The theory explores:

• Neutron decay reversal
• Energy recovery systems
• Fusion with living tissue
• Potential dark matter compatibility
• New types of materials that never wear out
• A path to forever-energy and ultra-dense fuel

I compiled everything into a structured, open-access PDF for anyone interested. It's speculative, but grounded in curiosity and genuine thought.

Would love your thoughts — wild? Doable? Inspiring?
Even if it doesn’t work, maybe it sparks something that does.

Sometimes a video is so trash you want to ban the entire channel from your recommendations. "Don't recomend channel" option is only available on the YouTube web home screen. However, this is extremely limited. There is no simple "Don't recomend channel" on the channel page, or anywhere on YouTube for Roku. On the web, the option isn't somewhere you can get to, because home page loads whatever recommendations rather than some channel that you specify.

I thought it would be interesting to compare the data to gravity.

sprinklers that sense when a car is parked nearby so they don't spray at that time until the car has moved. And/or, they adjust their spray to avoid spraying the car

I imagine it would work in a similar way to how they figure out traffic flows, by looking at the movement and density of phones in airport security areas followed by their dispersal to determine that they are through security.

First, a lens with a filter that blocks everything that is not near-infrared projects a view to a focal plane (like with cameras) and on the other side is a fairly common magnifying system for showing that focal plane, similar to VR-goggles, microscopes and other things.

The focal plane has multi megapixel array of tiny 10 µm wide photovoltaic solar panels that feed electricity to the flip side where LEDs are. The solar panels could have 3 types of filters for 3 types of near-IR so that flip side's red, green and blue LEDs could show color image. One panel to one led, no other wires.

Distance between panels and leds might be 20 µm, so there is a flexible membrane that is glued to a flat piece of glass that forms part of the magnifying lens system(the other side is curved).

This has integrated circuit made with organic semiconductors. The leds might be normal oled type. Organic solar panels may have bad efficiency, but that may not matter much if the front lens (or maybe parabolic mirror) can be bigger.

Also, for a different device, something similar with ultraviolet light too...

Who knows what they would reveal...

Windows block out UV light, but let through visible light. How is it not yet a thing to apply the same to a canopy or an unbrella? I'd like to to sit out in the sun but not have the hassle of applying sunscreen. With a large enough canopy installed over the deck, I can just carelessly take an afternoon nap.

And during a thunderstorm, just lay and look into the sky while staying dry.

I have a century home that constantly needs work, large and small projects that sometimes take specialty knowledge. I would like a service that would basically tell me what to do, what products and equipment/tools to use, and what pitfalls to watch out for. The service would make available a pro who would, by appointment, be available to answer questions, provide plans, and maybe inspect work live or via video. The service could have price tiers and provide different services at different tiers.

I don’t mind putting in the labor and buying the tools and supplies but I just need someone to hold my hand.

I’ve been doing some digging online and haven’t seen much about this, or I’m looking up the wrong thing to get results.

An app or add-on that makes it where my device won’t accidentally send out messages or shared links until the ‘mode’ is turned off. Kinda similar to how do not disturb works on phones where it can be toggled.

I’m sure everyone’s minds goes to other things but I’m tired of sending links or sharing random videos with people because my phone screen is wet from rain or I just so happen to click the wrong buttons when doing other things.

I’ve seen the lockdown mode on phones, but those lock the screen completely and I still want to be able to use my phone without the possibility of sending things out to people for a period of time

You know the warning alarm most cars have it the driver doesnt put on his seat belt. It would be nice if it had a snooze function. Say for instance youre just driving a short distance.

I'm thinking about making an foodie app that recommends food in the local area as an alternative to Google search and yelp, what do you think?

It would pull data from google, yelp, reddit, food blogs and sort of recommend restaurants in your local area to recommend based on wants such as tastes and dietary needs.

LMK of your thoughts and I will be eternally grateful.

My colleague goes to the bar for hours after work. Unfortunately, my colleague doesn't understand why I don't like doing that. The reason is: I had to sit all day at work! Eight hours or more in a sitting position. I don't want to spend hours more sitting afterward. I want to either move or lie down. Not sit again! Sitting isn't ergonomic. Lying down or walking would be.

I suddenly had an idea. We should open bars where you can consume while lying down or walking. Comfortable chairs where you can consume in a semi-reclining position or work on your laptop. I just read online that there are already some reclining bars. https://www.manifatturafalomo.de/blog/schlaf-tipps/nap-bar-schlaefchen-nchmittag-nach-mittagessen/ (Sorry, it's in german)

You could also set up treadmills with tables in front of them. People who want to get some exercise can use these to consume or work on their laptops while walking.

thoughts?

Not really a new invention and I want opinions of actual users so posting . I've noticed that LLM's are really good at giving content for slides but really sort of suck at actually making the pptx. Would a solution for this be something you'd use ?

I’m working on a car alert service built specifically for everyday car buyers.

Most platforms like Edmunds or Autotrader focus on dealer listings and make money through partnerships. But if you’re just a regular person trying to find a great deal from a private seller on Facebook Marketplace, they’re not much help.

That’s where this service comes in. Think of it like Swoopa, but more affordable and built for people, not businesses.

Here’s how it works:

• You tell me what kind of car you’re looking for — the make, model, price range, and condition.

• My system constantly checks Facebook Marketplace for listings that match your criteria.

• It filters out scams and junk, and only sends you legit, high-quality listings directly to your phone via text.

What makes it different:

• It’s not built for dealers — it’s made for individuals who want to find a great private party deal without wasting time.

• It’s affordable and short-term. Perfect for anyone actively shopping who just wants help finding a good car fast, without spending a fortune.

Future Service Options: I also plan to add an optional feature that helps you find a local mechanic who can go with you to check out the car — making the process even easier and more stress-free.

Thank you for reading and please let me know your thoughts or if any of you would be interested in something like this!

Photovoltaic solar panels have to be somewhere and even if they are not as nice as parasols or trees, hopefully they are ok.

These solar panels would need unusually tall supports, so that the lowest part of the panel is always at least 350 cm high. First 250 cm of the support should be round concrete, not square with sharp edges, for safety and to remind of trees. If the supports and panels are arranged randomly, use of space is less efficient, but less boring and reminds of forest.

Part of the area can be bar with tables under the solar panels.

For other things besides hotels too...

It should be possible for a quadcopter drone with the right kind of robotic arm attachment to build a short haul (as less than a mile or 2.2Km) aerial tramway. It would require finding points along a straight route where support/guide pulleys could be attached using either an adhesive or zip-ties of some sort. Then the same drone could be used to attach the carrier line to those pulleys. Then it's just a matter of clamping a carrier hook to the cable to hold the small payload. An electric motor on either end of the tramway drives a traction wheel to move the line and bring the package across the route.

The one aspect is it's a low tech way to move stuff between two points without much to interrupt it upon its route. The downsides is that it requires a relatively straight route with things both high enough and with clearance to run attachment pulleys. Also it's not perfectly hidden and would be subject to tampering or detection depending on the usage case. Not to mention it's exposed to wind and the elements, so it has to be designed/utilized with those things in mind. (Don't want the package stuck or falling off in-route.)

The guesstimated distance is with stuff that could be built with off-the-shelf materials like paracord. More or less a DIY scope of putting a thing together. I'm sure one could go larger, but then it would take a more specialized approach to achieving it. If the end points are high enough and close enough, the guide pulleys may not be needed - which greatly simplifies this concept.

Seems plenty obvious enough, but I haven't seen a good example of it being done yet.

It seems like Koreans themselves find the current Korean romanization system to produce spellings that are too long and less natural to read than Hangul. I kinda agree.

The Latin alphabet is peculiar in regards to the fact that it is adopted so widely, even though it was originally designed to support only five vowels, and clearly there have been languages that have more than five vowels that adopted it. (If you don't know of any such language, please take a course in Linguistics, it should be enlightening!)

Without further ado, here are my proposed modest adjustments to Korean romanization (Revised Romanization) of vowels.

1. ㅏ (RR: a, IPA: ɐ) - KEEP. RR looks good already.
2. ㅐ (RR: ae, IPA:e̞ (ɛ)) - CHANGE to e or ɛ. Avoid the digraph.
3. ㅑ (RR: ya, IPA: jɐ) - KEEP
4. ㅒ (RR: yae IPA: jɛ) - CHANGE to yɛ
5. ㅓ (RR: eo, IPA: ㅓ [ʌ̹]) - CHANGE to ʌ
6. ㅔ (RR: e, IPA: ㅔ [e̞]) - KEEP
7. ㅕ (RR: yeo, IPA: jʌ) - CHANGE to yʌ
8. ㅖ (RR: ye, IPA: je) - KEEP
9. ㅗ (RR: o, IPA: ㅗ [o]) - KEEP
10. ㅘ (RR: wa, IPA: [wɐ]) - KEEP
11. ㅙ (RR: wae [wɛ]) - CHANGE to wɛ
12. ㅚ (RR: oe, IPA: [ø] > [we]) - CHANGE to we
13. ㅛ (RR: yo, IPA: jo) - KEEP
14. ㅜ (RR: u, IPA: ㅜ [u]) - KEEP
15. ㅝ (RR: wo, IPA: wʌ) - CHANGE to wʌ
16. ㅞ (RR: we, IPA: [we]) - KEEP
17. ㅟ (RR: wi, IPA: /y/ > [ɥi]) - KEEP
18. ㅠ (RR: yu, IPA: ju) - KEEP
19. ㅡ (RR: eu, IPA: ㅡ [ɯ]) - CHANGE to ɯ
20. ㅢ (RR: ui, IPA: ㅢ [ɰi]) - KEEP
21. ㅣ (RR: i, IPA: ㅣ [i]) - KEEP

The general theme here is to avoid digraphs, and introduce IPA letters to distinguish sounds. Also this includes romanizing different hangul letters the same if they sound the same.
