7 cheapest way to attach your cell phone to a tripod and many other ways to set up anywhere else

youtube

No need to watch other people’s videos since this video covers all! The cheapest and easiest ways for all different situations are covered. No problem even if you don’t have any equipment.

There are 5 Billion mobile phone users in the world. For various reasons, you may sometimes need to place or attach the cell phone to somewhere where there is no obvious mechanism for attaching it. In addition, perhaps you do have regular proper holders or adapters, but since you go to different places with your mobile phone, you may be somewhere where you do not have the access to your usual gear, hence we have provided many different ideas in this video.

I promise some of these ideas cannot be found anywhere else. To make a DIY device, other people may say buy this and buy that, but I always use what I have on hand. So bear with me for the longer video since I will show you various different ways that can then be adapted to suit your own situation and inspire you to create something new.

I have published couple of related videos in the past, here are the links:

15 Ways To Not Smash Your Fingers With a Hammer

youtube

After comprehensive research on this topic including visiting the Hammer Museum in Alaska, we present you with these 15 tips. We systematically analyzed the processes and the components involved. For the first few tips we have invented, I guarantee you have never seen anything like these before.

Because there are many different sizes of nails, people with different hand-eye coordination capabilities, different hardness of surfaces, different construction environments, some of these tips may be more useful than others. You don’t need to master all of the tricks, you just need to identify your own problems and choose the best one or the cheapest one to suit your own situation.

Of course, if you never use a hammer, and always hire someone else to do your repairs and remodeling, you will never smash your fingers. Short of that (or having someone else hold the nail while you wield the hammer:) ) , the more hammers you use, the greater the likelihood of injury, especially when you are tired. Thus a good practice is to always be alert, have consistent execution, and constantly remind yourself about sound posture and correct process. Good luck to your fingers.

The easiest and the cheapest way to purify the room air

youtube

The smoke from California fires caused air purifiers to be sold out at many locations. Today I am going to show you how to use what you have or can probably still get, to the room air clean. Compared with the expensive air purifiers on the market, these DIY air purifiers are equivalent but at a much cheaper price.
Three reasons they are cheaper:
1. if you already own a fan, then you don’t have to buy another fan.
2. when buying filters, you can buy whatever size is most suitable for your fan, or is cheaper
3. unlike air purifiers, the filters as well as fans can be bought cheaply (because both items are high volume commodities).

For example both the fans and the filters can be bought for about $15 each.

Build an easy & free home security system in under 5 minutes

youtube

The first part of this video is about how to quickly build a free basic home security system in under 5 minutes. I have listed many options for you, but you don’t have to choose all of them, work with what you have and is the best for you. It is easy — if you are a cell phone user, you should be able to do it. It is usable as it is, and will be sufficient for most users.

However, it is also possible to add features which will improve it. To help advanced users, I introduce a couple more phone apps to get you started. Through the explanation of how these apps work I explain the basics of internet and the home gateway router. I show the communications between different devices among different networks. Understanding this diagram will help you to debug all parts of your security system.

Since it is easy and does not cost anything, why not give it a try? In my neighborhood, burglaries have been increasing. Some people blame this on California’s Prop 47. California’s Proposition 47 downgraded a variety of “non-serious, nonviolent crimes” that had previously been considered felonies to misdemeanors. A thief may now steal something under $950 on a daily basis and it will never rise to felony status. Without your own security cameras, it’s difficult to catch thieves unless they leave fingerprints. One by one my neighbors started buying security cameras and services. Even if you have already bought some cameras, this can complement them by adding even more cameras. I have covered every single one of my windows, and hope that in addition to providing camera footage of any motion around the house, this will also act as a deterrent to possible thieves.

So get your security cameras ready because the latest is that California will end cash bail next year. When the new law takes effect, thieves without money will no longer need to worry about cash bail because by definition theft is not a violent crime.

How To Make A Free and Accurate Kitchen Scale

youtube

This kitchen scale took me only a few minutes to make. My invention uses a few commonly available materials and tools. It is free and pretty accurate. It is also durable and easy to use. To improve the accuracy, I have provided a few guidelines to help you to understand the usage and find the optimal accuracy for your own situation. Since all the parts used in making it can be used or shared with your other projects (the paint stick can be used as a ruler), it does not require any space to store it. I hope this video can inspire you to invent useful devices with things available to you. This kind of project will also nurture your kids’ creativity and future-proof their skills. If you have any tips, please leave a comment below.

I will also show you how to make another very small scale that is hidden inside your shopping bag. This way you can do comparative shopping discretely. If you don’t have the time or the ability to make the first one, the rubber band scale is easier to make. But it does need more time to re-calibrate especially if you stretch it too much.
