Dual-Screen Smartphone

I’ve always wanted a dedicated keyboard. A great solution is to have a second screen that is always-on for notifications, weather reports if it will rain, messages, news ticker, a game controller, a fingerprint scanner, emojis and so on.

A second screen dedicated to these will save battery and you don’t have to unlock your phone while cooking or anything else.

A Simple Electric Motor

This took me days to figure out what’s wrong. Although I got it from the Internet on how to make this, and there are step-by-step instructions, I just couldn’t figure it out. Luckily, after searching, I found a video that explains for this to work, you need the coil to have only one side exposed in a vertical manner. You just have to sandpaper one side of the coil at both ends, touching the electric current from the battery.

Here is a picture:

Here is a video demo:

For this to work:

  • You have to have a strong magnet.
  • An Alkaline 9 volt Battery.

GLASS BOTTLES

How I wish that they use glass bottles again instead of plastic pet bottles. Glass bottles can be reused by dipping them in antiseptic solution and it is clean again, while pet bottles are just thrown and piled up in landfills that cause pollution on seas, riverbeds, poison the soil, kill wildlife and damage the ecosystem. If you’re going to recycle plastic, you’ll need expensive equipment and costs are high. While glass bottles are more cost-effective and have longevity.

Reuse is better than recycle.

Silent Remote Controlled Doorbell

What if you don’t want to be disturbed by the loud sound emanating from the doorbell? Isn’t it cool to have a device that instead of sound it uses light to tell there’s someone at the door while you’re busy in your room?

I have invented a remote-controlled doorbell that lights up when your
spouse or children can activate when they arrive. By using radio
signals, you can turn the light on or off.

Here is a video demo:

What I did was bought a cheap remote-controlled car toy, and instead
turning on the motors, I attached it to a breadboard with resistors and
an LED. So, every time I press the remote, it will light on, and depress
to turn the light off.

Here are sample pictures:

However simple it may seem, it needs a lot more than this. It needs
encrypted signals like on your phones to make it secure. And, it needs
to have a smaller scale for convenience and portability like a keychain.

 

Suggestions I could make is to have a companion app that sends you
SMS, or notifications. But, this may cost extra and defeat its purpose.

 

Anyway, I hope you liked it and please share this website with others because it gives me the motivation to invent more! Thank You!

Electric Fan, Exhaust Fan with Remote

I am currently studying electronics and had an idea that you can reverse the rotation of an electric motor that can be used for a wide variety of purposes. For example, an electric fan’s motor rotation can rotate clockwise AND counter-clockwise without any mechanical but pure electronics. By reversing the polarity of an electric charge, the motor will rotate in a reversed motion. Practically, this can be applied in electric fans and serving also as an exhaust fan.

Another idea is to use a remote control to the fan, for the customer’s convenience’s sake. Funny, because this is used primarily on children’s toys like remote-controlled cars or RCs.

Here is a render of the electric/ exhaust fan with remote control:

Electric Fan with Remote and Reverse Feature (2)

 

Note: I used 3D Rota-aire design as basis.

I have to point out from the render that the rotation of the grills is different from the rotation of the electric motor.

Thank you!

 

 

 

 

 

 

 

Internet Traffic vs Road Traffic

Actually, it’s just the same!

We all know that there are times when the Internet is slow and there are times it is fast (like 12 in the morning). But, when you send a message on Christmas Day, they will receive it on New Year’s Eve. Yes, I’m quite exaggerating but this is the reality.

Therefore, to solve the traffic problem, you must schedule it since it is basically a timing problem.

For instance, after a busy intersection, the cars speed up until the next intersection. Since there are no stops in between, they all stack up on the next traffic stop. Then, there’s your bumper to bumper traffic.

To solve this, you must put more stops in between like putting traffic lights, or traffic police.

Now, back to the Internet. Well, the best way is to observe first what time is fastest and when it is the slowest. Hopefully, your friends and relatives will receive your greetings on Christmas Day.

Digging Ditches to Direct the Flow of Flood Water

I was watching Puffin Rock on Netflix (because I am studying cartoon animation) episode entitled, “Pond Life,” when I noticed a situation when Oona dug a ditch from the pond to save the tadpoles in a puddle.
Hhhmm, I wonder if we could dig ditches beside roads that lead to the sea, we could keep the roads from flooding and let rescue efforts be more effective and faster.

Here is an example I got from Google images:

digging ditches alongside roads

However funny it may seem, it is an elegant solution on putting bridges across ditches when sidewalks are non-existent. Our country doesn’t even have decent sidewalks and when you are going to dig ditches, then it may be a problem since there are stores alongside roads.

Maybe, it depends on designing these things but it seems simple, cost-effective and easy enough than other options.

 

 

 

Replaceable 9-Volt Battery LED Light Science Project

LED lights and lamps you buy have rechargeable batteries inside, and I must say that it’s a pain to replace them. After how many charging cycles and even though it still works, you just throw the whole lamp away and causing so much waste of resources. So, why not use the LED lamp that lasts using a changeable battery you buy almost everywhere?

I bought a cheap LED flashlight that works great and replaced the rechargeable battery with a 9-volt Eveready battery. Simple enough.

I hope this would help manufacturers design a rechargeable battery that can be replaced easily and make even more affordable.

Harnessing Radio Waves For Electricity

Radio waves are also electricity didn’t you notice? Waves that travel on air to your phones or AM/FM radios by capturing it to an antenna. So, by creating a smaller “radio” transmitter for your home, you can also wireless charge your devices.

A UK firm has also discovered this and developed this idea using multi-band antennas to capture different “radio stations,” to increase the electricity harvested, for low-energy IoT (Internet of Things).

Click here: http://www.telegraph.co.uk/technology/news/11901430/How-energy-harvested-from-disused-radio-waves-could-power-the-smart-home-of-the-future.html

This is exciting times since by this you can wonder how this technology could change our lives by using “free” electricity. Just as Nikola Tesla (the inventor) has envisioned. It’s like that movie where Doctor Octavius wants to harness the energy of the man-made sun to provide cheap electricity for the whole world. Not a lofty goal but perhaps a crazy one (haha).

 

 

Smartphone That Lasts

I don’t need to play games because I am an adult. I just need a phone that lasts for days on a single charge for email, messaging, voice calls, and essential backups, etc. So, I’ve been reading and studying about electronics, since smartphones are electronic devices, and found out that for the battery to last longer, you must have these specs:

Single-core Processor

Today, we have octa-cores already for faster processing. But, we do
not need this for office work. Multi-core CPUs only drain so much battery that is usually used for gaming.

Lesser Screen Pixels

We don’t need more pixels. I mean, my ordinary phone works and looks great without having a ridiculous amount of pixels because this too can drain a lot of battery.

Cooling System (temperature)

The temperature could also affect processor speed. Having a better cooling system makes the CPU run with higher voltage without destroying the phone.

Big Battery Capacity

I don’t care about a chunky-looking smartphone. What I need is a bigger battery for more capacity.

Newer, More Efficient Operating System (OS)

Upgrading to a new OS fixes bugs that slow down your phone. Newer versions mean faster, more reliable, and with the new Android, lesser bloatware and more of the essentials.

To sum it up, a single-core processor, lesser pushing pixels, a design-focused cooling system, a bigger battery, and a more efficient Android without bloatware, makes a phone that is easier to get our jobs done.
