I bought a simple D10cm USB fan some time ago. I was surprised at the air flow from this rather cheap high quality fan was so good. At times when the heat is to high. A fan is absolutely necessary.
Since there exist larger diameter fans. From 10,13 to 18 cm. I wonder if they could be used in emergency situations. For field hospital like situations. Where there is no access to reliable electricity. These fans can run on a limited amount of solar power. Rated at 2.5watts 0.5A 5V. I could have 3x18cm USB fans on separate powerbanks. Thats a 54cm fan on battery power.
As a livelihood starter why not assemble a flower growing kit? Then to generate interest and keep customers coming to your store. A modern approach to this would be to make online instructional videos.
This means people can come to your store and ask questions in person.
If there is no internet access in your area. You can still make videos and sell them offline. This using a simple Wifi transfer application from the smartphone or PC to the customers smartphone.
I assume something like this will keep customers coming for the flowers, the offline videos and the possibility for in person questions.
Africa is on the way up in the world. For this positive trend to continue Africa has to lead in finding smart ways to handle conflicts.
Sanctions could be an answer. Definitely not military action which could lead to war. Realizing education is a way forward is equally important as realizing peaceful action is actually pretty sustainable.
I wrote a long time ago about the possibility of running a computer or mobile on a limited amount of solar panel.
Because it works pretty well using the smartphone as a screen for the raspberry pi 2. I thought I give it a go with a small 7watts solar battery charger.
I will try this setup tomorrow. No sun here in Sweden at this time though. Actually I thought the solar panel battery charger was broken. I assumed it would work with LED or cfl lights in the kitchen. It did not. Ok I got 0.25 Volts after placing it near the cfl. Not enough for charging. Which means it wont show up on the smartphone or even light up a light emitting diode. However with natural sunlight it worked just fine.
An easy way to power the pi2 and the phone would be to have two 5000mAh powerbanks. One for solar charging and one for power.
The same idea really but with low power electronics your not so vulnerable of power cuts. So for those with a bad power grid. Why not have a computer like the raspberry pi2 in hand. Then you could continue coding or doing some office work (LibreOffice) on the pi with just two powerbanks and a solar charger.
When I remembered a color that look fluorescent I thought. Could this surface absorb energy. Could there exist an endothermic process . A process that absorbs energy from its surroundings and emits light.
So my guess is that maybe there should exist something new like endothermic fluorescence.
To promote Linux in general or your favorite Linux Distro. Why not create an emoticon series with the mascot or the logo as the star. It does not have to be a logo. Perhaps something that people could relate to like opensource could also work.
My guess is that everything you sense or think can generate feelings. Also since you base a lot of decisions on feelings generated in the brain. I wonder if this decision making enabler can be taken advantage of in computer applications.
So an important application is database search. Like when you google. Where you want to search through a lot of data fast. Then could not this search be enhanced by feelings. Computer feeling based guesses that makes the search much more accurate.
I assume this is possible since the feeling space is limited or rather small. That is. There are probably not a lot of very different feelings. If the computer knows the target feeling you want when you search then it can sort data faster. Much like sorting by color is faster than by object recognition. Also the selection will also be more accurate.
Another application could be the search for more life in the universe by adding a feeling component to the calculations. That is. Clustering the picture of the universe into different feelings.
So my idea is that you can enhance computing tasks by computerized feelings.
One easy way to do this would be to add something like a string of emoticons to your google search.
To maximize the chance of life to exist in the universe I wonder if planets or a system of planets due to their different sizes can adjust its gravity a little? Maybe life works best under certain optimum amounts of gravity. Thats what I’m thinking.
Philosophically. There should exist other instances where you need to use the concept of balance other than driving a segway. I wonder if the EM drive could be such a device.
So if getting thrust from the EM drive is a balancing act. Then you need to take advantage of machine learning to generate it.
Since you input a lot of instances of random reflections of microwaves in the chamber. Maybe noise cancellation should be a feature of the EM drive also.
From the principle of balance and that we use this to be able to walk. I wonder if you could propel a spaceship by climbing or walking in space. This by shifting balance on different space length contractions?
With this you could have two or more synchronized EMdrives working together.
This sounds like something out of science fiction but maybe something can be inspired from this idea.
I wonder if you could just skip the radio, battery and advanced electronics for simple buttons and toys.
The idea is simple. With python its possible to detect the frequency of a note. Maybe machine learning can detect the mechanically generated sound from physical buttons.
The idea is then that you can create controllers or other toys that don’t require electronics or batteries. The generated sound the button then makes (like a whistle or similar) controls what happens on the screen with help of a microphone, a Raspberry Pi and python.
I was wondering what happens to molecules in the air when you accelerate them over a longer period of time.
Philosophically there should exist important inventions for the basic types of motions. So my idea is that we should see what could be done with linear acceleration.
From looking at a turbo air conditioner I was thinking that maybe one could just add acceleration chambers of smaller radius after each other. Like when you swing a weight attached to a thread around your finger.
I wonder if you could create a win win situation for refugees and the open source community. By sponsoring a refugee dedicated programmers coder bounty. I’m thinking this is beneficial for their future. Refugees get paid to learn to code like a pro from real problems.
*Even though the bounty could be solved someone else. I think there should exist more ways to provide aid. Sponsored work that provide a real benefit for the refugee could be one way I think.
I finally got the old midi keyboard M-audio Radium to work with my raspberry pi 2. I’m so glad. It has been in the apartment storage for so long. Now I can do everything on a pi with mobile as the screen. Program a game and make music with a simple midi keyboard and LMMS as the music software.
This is what I love about Linux.
To get it working
I used midisnoop on the pi to verify that the midi keyboard was working. After plugging in the keyboard you can check with ’aconnect -i’ in the terminal and it should show up. I had to do ’sudo apt-get install midisport-firmware’ in the terminal first.
Planning to do a pixelized international karate game. ikPixel.
Eating right is very important. Therefore I wonder if we could as a service unload some of the work done by the family in getting the food on the table. I mean. The list of different food items is pretty big.
We already have food services. Could they also offer something adapted for pregnancy.
Maybe ensuring that the family got these types of food in the needed frequency is as important as having written documentation . Or maybe more important.
Why don’t have a text tv overlay with two languages? With text tv. You know the old technology. We have an option to show subtitles or simply no subtitles. So why not mix for instance Arabic text and Swedish text for our news and morning shows. Together as one connected subtitle.
I think this could be an effective way to learn a new language like Swedish. This because its easier to learn visual text than to remember spoken words. Here you have everything at the same time. No reason to limit the learning experience.
For language learning in general. The will be an important idea if we do this for youtube or other online video.
That is. In youtube we should have the option to show two subtitle languages at same time.
I was looking for a way to program on the phone and I think I found an interesting setup.
What I used was:
A raspberry pi 2
Powerbank (5000mAh battery)
2 USB phone charging cables
Pillow (to lift both the keyboard and phone)
VNC viewer (android app)
USB Tethering (share Internet and connect with the Pi)
PIXEL (raspbian powered os on the raspberry pi)
To start with.
I connected the pi to the smartphone, keyboard and powerbank. You only need a usb charging cable for this. To use the phone as a computer screen you need VNC viewer. To connect you can use Internet sharing by USB. This will make it possible for the vnc viewer on the phone to connect the vnc server on the raspberry pi.
Then when your done. Why not put the phone and the keyboard on a pillow and the setup feels as good as a laptop. Sure the screen is smaller but since VNC has automatic scrolling when moving the mouse it does not matter so much. Just increase the font size. VNC has a built in mouse that works just fine. No need for an external.
I was surprised the setup worked so fine. Since it runs on a powerbank you could charge it with a solar panel.
Voila! And you get yourself a cheap solar mobile Linux PC.
I was wondering how to improve programming on the smartphone. Then I got the idea that maybe its possible to code using a chatbot.
The idea is that by having a conversation with the chatbot. The bot could generate code, answer questions or provide guidance. For instance on error messages the bot could provide additional information given questions from a novice programmer.
We have a lot of programming languages like c++, python and others. But they are not so phone friendly. So why not invent a new programming language adapted for smartphones or feature phones. With their small screens and slow typing keyboard.
The reason could be to teach programming to a bigger part of the world. Those who only have computer that is the phone. To be able to learn a little programming they probably don’t need to write super long code. However I think the knowledge of writing simple text based code could go a long way.
The phone is the most commong computer. We should have a free and open source programming language system on it.
Sometimes my eyes doesn’t focus properly because I am tired. Then it occurred to me. How much is reading and how much is guessing the word correctly. I assume this is an important skill especially for those who have trouble reading. Those with dyslexia for instance. I don’t know the best way to practice the guessing technique but I thought a first try would be to blur the text with different strengths and sizes.
So my idea is that by guessing the blurred text you get better at guessing the words and also at reading the text. Since your not so affected by poor visual quality.
I think this could be made into a teaching app. Guess the sentence of words from a blurred image.
Another idea is to have a ruler. In Linux this is easy. Just create a black bar in GIMP and then display it using the terminal command ’display’. Set the window to always on top for the image of the ruler and you good to go.
