A prebuilt loading screen for developers

I built An API/Service that provides developers with loading screen that contain news articles based on locations, fun facts as loading screens, if there is a wait time of a few mins the load screen will keep the user engaged.. and not feel like they are waiting forever for the content to load, the API service would allow the user to add interactive loading screens quickly and will have access to updated content, this can be used for apps and websites..

here is a preview,

magsafe second screen for phone

Idea - a magsafe second screen for a phone. It would be like a folding front cover case, but on the inside of the case would be an OLED screen. And it would be attached via magsafe to the back of the phone, so if you're doing things like ebook reading (or anything really) you get double screenspace

Better than a folding phone because you could completely disconnect the second screen if you want to

a gym chain the does 24/7 on weekends

Planet fitness used to be 24/7, but many locations have started only doing all night Monday through Thursday, closing the other nights. The issue is, many of us are wanting to go at 11pm on Fridays, Saturdays and Sundays, and the inability to do so kinda just begets more not wanting to go...kinda spirals out and makes the whole fitness thing become sour, at least for me it kinda does.

My idea/solution would be a gym chain that focuses on those nights (Friday, Saturday, Sunday nights)

They could do 24/7 Fridays, Saturdays, and Sundays...me and I believe many others would pay for a "full featured gym" with full lockers and big gym floors with dozens of each type of equipment to essentially get the planet fitness members who miss late night workouts on the weekends to join and pay.

This gym could then close earlier Monday through Thursday nights so planet fitness could continue getting the late night people on those nights.

I mean, I'd prefer planet fitness just doing 24/7 for all gyms, or at least more gyms, but if that doesn't seem like it's gonna happen, then I welcome some market competition.

Update / edit - maybe as a way to entice people to work on the weekend nights, this type of gym could be relatively expensive. Like, make it at least 40 dollars a month. That way, it helps with revenue and profit, as well as helps to pay the workers who are taking these late night weekend shifts.

Edit update 2 -

Another idea - maybe planet fitness could pay time and a half or double pay to weekend overnight workers to entice people to take the shifts.

A petition-tracking extension for change.org

I make a lot of change.org petitions usually to save TV shows and they have somewhat worked (as in I've made the petition, the show's gotten renewed, I don't know how direct the causal link is) but as I make more and more it's harder to keep track of ones still active so I'd like to propose (if there isn't something like that already) a browser extension where you can select a petition and just see the signature count go up in some part of your browser window aka not have to keep going to the damn page

Wireless connection solutions for niche applications

I would love to see some application of wireless charging implemented on a larger scale. I.e. instead of running a recessed outlet behind my tv, just have a magnetic wireless power input behind the wall that I can "click" the TV's power input to. Or similarly, an extension cord which utilizes the same concept (this idea came about me trying to plug in a powered coffee table without wires showing or cutting into the rug). Currently, I know similar technology exists on a smaller scale for commercial applications like electronic locks, and consumer applications like phone chargers. I also know this may not be practical in many cases due to issues with arcing, insecure connections, etc. but I still think its got a lot of potential! I also think there is some merit to the safety of this type of technology in that there would be far less mechanical wear to the receptical since nothing would be physically plugging into a wireless outlet.

Lightbulb ID: Two prong male 120v socket from old microscope

Anyone know what kind of bulb this is?

16.5-17mm ID socket with two male prongs. Wired for 120v. Unthreaded press in socket. From an old 1970-1980 microsope.

Thinking bulb should be a small filament bulb with no threads and with female sockets for pins.

Thanks for any help!

Instant window - Invisable roof

This idea will definitely be stolen from me. Like everything else in my life, just remember where you saw it first.

T Platt 4-25-84 Jacksonville, FL USA

Instant Window- A camera on the outside of your house, a projector on the inside of your house. Creating a window that you can see out of, but nobody can see in.

Invisable Roof - same concept. Imagine laying inside on your couch, looking at the sky above, projected on your ceiling.

The Future of Walls Inside our homes - it may be a while before it gets to this, but eventually we will have the option to hit a button, turning our door invisible or walls Invisable through projection. It would take many multiple angled cameras and sensors and Ai, to get image from someone which is close to our door, but it could be done. Probably already has for different scenarios, just not offered to the public for home security yet.

Because people with that kind of money are to busy watching us virtually like the creeps that they are. Looking inside all of our homes using wifi imaging. They havent thought about something this simple.

Strict Parents and jealous spouses will use it to make their entire house Invisable, but I say to those pieces of crap...why did you construct walls in the first place.

An app that is a face that listens to you

I was giving a presentation on zoom for work the other day and thought about how annoying it is to give a presentation when everyone is on mute and has their cameras off, so you do not get any audience feedback. I miss seeing people make eye contact and nod.

I wish there was an app that featured a sound activated face. It would look toward the sound when noise is detected and nod slightly occasionally and when the sound stops. I could put it in front of my computer when I give presentations so it feels like someone is listening.

One dumbphone to end the chat wars for good

In a niche market, there are purpose built dumbphones designed to be simple, focused, and free from "distractions."

Two main features of this minimalist phone are calling and texting. However, problem: texting sucks, so we can take a page from Apple's playbook and have texting traffic be automatically redirected via a proprietary network over the internet rather than being stuck on cellular networks' SMS or RCS service. The main distinction from Apple would be that iMessage is not available on Android (about half the population of phone users depending on your country). Cellular connectivity would be an option at purchase in order to enter the market for non-cellular devices as well (think iPod touch).

The chat app would be paired with a dumbphone as its only option. However it would be made available on iPhone's and Android's app stores. Because people with this limited phone do not have an alternative, social groups in theory would be incentivized to use this chat app by process of elimination, giving this app an advantage over other chat apps.

Idea of a drone design( subject:peregrine falcon )

I am 16 and have an idea of a drone design but no idea how to execute it . I while traveling saw birds especially eagles and saw that they barely flap there wings and Use their body pattern to glide in air . And I wonder what will happen if we infuse a drones feature in a body shape of peregrine falcon . Specifically peregrine falcon because it is tge fastest bird with the best aerodynamics. So my idea is that we take the body of peregrine falcon Use plastic or lighter substance to make the body Then on the wings part Use two powerful thrusters for Example 12 kilowatt hall thruster ( I don't know any thing about these thrusters I just Google the most powerful electric thrusters) Now mounting these powerful thrusters on the wings the peregrine falcon will float and go higher up in the air Approx 3500 feet cause that's where peregrine falcon fly . Now when the drone will reach the required height the thrusters will change its direction from below to side and then the drone will use the physics of the birds flight and will glide at great speed and the thrusters will further increase the speed. The place where the birds eyes will be there can be two compact and yet powerful camera for an instance the s24 ultra's camera (as this is the most powerful camera I know which is compact)and in the place of the beak of the falcon drone micro sensors can be planted which can gather resource full information This drone if flew at a great height can gather huge information and even may predict weather of small area, it can be also be used for cloud seeding a small area,this bird drone can also capture great takes and shots from a bird eye view as a very powerful camera is installed in it. (Now pls don't judge me for giving this idea I am 16 and just observed the birds and came up with this idea. I just want more information on this topic from u fellow reddit users and tech enthusiasts. Pls enlighten me with ur information if I am wrong by anything and identify all the possible errors . If somebody likes this idea I thank u for reading this ) thank u

Let me tell the online ad-bots when I've made a purchase.

Now that I bought a bed frame it's not helping anyone that literally every ad I'm being served is for more bed frames. And no, I didn't go with that one brand, it's way overpriced.

If ads are going to be inescapable, let's at least have them be relevant.

Precast concrete elements with special features: echo reduction shapes, attachment points and rods, steel mirror, shelf

Wavy profile to reduce echos. Better acoustics. May improve sound proofing too. Shape sizes are roughly same size as wavelength of the sound waves. May have some fractal shapes on multiple scales for multiple frequencies, resembling a koch-curve. Avoid 90 degree angles.

Steel grids, rods and hooks for attaching things, in walls and ceiling, welded to normal steel rebar that is inside the concrete. For example, for curtains, paintings, lamps and acoustic soft panels.

While ( stainless ) steel mirrors are not the best, they work for something. Welded to rebar. Makes wall stronger.

Mold needs to have special shapes on at least 1 side. Combining wavy profile to hooks and other sticking out steel is tricky but can be managed.

One way to make uneven mold is to hit steel with a sledgehammer multiple times on random spots. That way it is wavy on 2 dimensions. Mold that is wavy on 1 dimension only gives stronger elements but echo reduction is less.

Shelf for rocks and stones, for acoustics and looks. Or for books etc.

For a special room: element with a small hole that can turn a room to camera obscura for natural projection optics.

Ventilation hatches / windows on or near 4 corners.

Hexagonal elements.

Octagonal elements that leave square gaps, maybe for car parking space walls or maybe gaps filled with windows.

A digital mind-mapping/brainstorming tool that looks like a yarn/thumbtacks/photos/scrawled-notes conspiracy theorist's corkboard

Mind-mapping/brainstorming tools tend to be sterile flowchart representations and don't lend themselves well to creative exercises. The title idea at least takes the blandness away.

FWIW, this idea came to me because I want to plan a novel and the usual tools turn me away for my purposes.

I think motorists need to communicate with each other better. So should all vehicles come standard with front and rear-facing megaphones so we can have vehicle-to-vehicle conversations?

If someone is hogging a lane when I'm running late to an appointment, I'd like to key the mic and tell the motorist in front of me:

"Hey bro, I have to be at an appointment very soon so may you please scoot aside so I can pass?"

If someone is tailgating me, I'd like to tell them through my rear megaphone:

"You're following kinda close. Are you in a hurry? Do you need me to scoot aside to let you pass?"

Has anyone else thought to put megaphones in vehicles already? Why hasn't this happened yet?

Would you use a gadget to test if your charging cable is good quality

Hi everyone! 👋

I wanted to share an idea my team and I have been working on and get your feedback.

We all know how frustrating it can be to deal with bad charging cables—they don’t charge fast enough or just don’t perform as expected. To address this, we’re considering designing a small, affordable gadget that could help you identify whether your current cable (or one you’re about to buy) is good quality.

The device would indicate cable quality through a simple three-state LED system:

  1. BLUE: Supports fast charging.
  2. GREEN: Good quality, but doesn’t support fast charging.
  3. RED: Poor quality, not worth using.

It’s designed to be small enough to attach to your keys and priced affordably (around $5) to make it accessible for everyone.

Questions for you:

  • Do you know of any existing solution as small and simple as this?
  • Would you be interested in buying a gadget like this?
  • Do you think this solves a problem you or others often face?
  • Are there any additional features you think could make this more useful?

I’d love to hear your thoughts—whether they’re positive or critical! 😊

Suicide as a Marker of an Intolerable Society

I seriously have to wonder, why anyone one earth would make the choice to leave? To escape their pain? To escape from the retarded apes who have no capability of understanding the pain any particular person is feeling?

I have to wonder why I choose to stick around… maybe I have too much pride to give up. Maybe I imagine… that it would feel quite good for my flavor of pain to be understood by the population, once and for all…

Why do people choose to kill themselves, I have to wonder? Are their brains defective? Are the signals communicating isolation, a bastardization of soul… too strong? Is this a sign of sickness, I wonder?

I would be as bold to say that it is the world that is insane. A world that rejects nature, as inferior to ascension beyond it.

We were not made for this world. We created a world greatly divorced from what we were designed for. But, I suppose it is nice that we can help people who take on immense physical illness, of no fault of their own, but an accident in genetics…

In order to achieve true world happiness, I reckon that we must approach are our true nature, to the fullest extent possible. We don’t have millions of years to become accustomed to this abomination to our nature. We are taking steps to reduce our own self-destruction. The final step must be the closest approximation to nature that we can tolerate. At least, that is what seems most intuitive to me.

$3 LED bulb lasts 60 years. However, this article is from 2009. 15 years later, why aren't they everywhere? Did a modern kind of Phoebe's Cartel prevent them from getting sold in stores?

[New $3 LED Bulb Lasts 60 Years - Clean Technica - 2009](https://cleantechnica.com/2009/01/29/new-3-led-bulb-lasts-60-years/)

In 2024, why aren't $3 60-year bulbs sold in every hardware store?

Did a modern type of Phoebus Cartel suppress that world-changing lighting innovation to protect their profits?

Next thing you know, a Big Pharma cartel is also suppressing cures for all sorts of diseases because marginally-effective medicines we need longer make better profits than cure-once medicines.

A real-life Pokedex! I think it's been talked about before but never seen anything

Has anyone heard of an app that is similar to a Pokedex for Australian animals or just animals in general? I've seen a few that you can just add observations to a list but it would be cool to have it more pokedex style. I'm not sure how this would even look/function but i'd love to be able to scan/take photos of animals while hiking and add them to my list. Or even if it's popular animals from certain locations like if I went to the mountains in a certain place and theres a list of popular animals you have to try and find etc. Hope that makes sense!

Edit: I'm aware of iNaturalist. I was more hoping for a fun version with extras like - points or badges/challenges for finding rare animals etc.

IoT plugs/bulbs/switches should use powerline networking for communication.

They're all already connected to the mains. You'll just need a hub and merely installing a smart plug/bulb/switch will integrate it into a physical network. No weird power on/off pattern > bluetooth > connect to smart devices temporary wifi network > select appropriate network and password etc.

Here’s an idea, especially for those of you who are in the medical profession. Find out why an increasing amount of mature adults are putting faith in conspiracy theories.

Key check breathalyzer for liquor establishments.

It would work like this. You get a small locker for your keys, there would have to be a computer system that may be scanned your ID then assigned the locker. Then if you want your keys back out you put in some money, a sterile breathalyzer mouthpiece is dispensed and you have to blow under legal limit to get your keys back.

I'm sure there are probably situations that make this impractical. But as someone who serves liquor, then watches their customers walk to their car, man I wish there were more preventative measures.

Meal box supermarkets

This possibly exists somewhere to some extent, but I've never seen or heard about it:

A supermarket that basically only sells meal boxes, like the ones you can subscribe to get delivered. Isles devided by cuisine or maybe food preferences like vegetarian etc. one isle for breakfast boxes maybe.

Everything comes prepackaged with exactly the items you need for the meal (maybe except basics like oil which could be sold separately in another isle for when you run out).

A lot of supermarkets have easy-meal kits with premade stuff that just needs a mix, but would be nice to be able to buy a box for when you want to do the cooking, but can't be bothered to find a recipe, write a shopping list and walk through a supermarket 2-3 times because you can't find that one item. And also nice for singles/people who are too busy to go through several meals before the next box arrives. And you'd avoid that packet of ginger which always rots because who the f eats so much ginger?!

Why aren't there any mainstream news channels on Twitch?

Everyone knows that cable news is a dying medium, most zoomers and millennials just get all their news from social media or news apps. So why don't media like CNN, Fox, MSNBC livestream their TV news channels on Twitch? They're already posting clips from them onto YouTube, this seems like the obvious next step if they want to stay relevant.
