Interesting gadgets for less than $5 [2. part]

Due to the great interest in the article in which I presented several interesting gadgets that cost less than $ 5, I decided to compile another list.

Note:  all the products I listed below can be purchased on various sites, but I posted links to Aliexpress because I have bought a lot there and have the most experience.

Detailed instructions on how to buy all these products can be found in THIS article, and if you have any doubts or questions, you can write in the comments.

1. FM transmitter for mobile

A small device that plugs into the 3.5mm headphone jack in the phone and you can broadcast any song from the phone via radio waves. Then, another device that captures radio waves can listen to what you play. So, this device turns your phone into a mini radio station. But since it is forbidden to broadcast a radio signal without permission, choose a free frequency. They are a little more expensive than $ 5 but are often at a good discount so they can be found for $ 2-3.

2. NFC tag

Today, more and more smart devices have active NFC, but often, ie. rarely, NFC tags come with the device. They are the size of a postage stamp and are quite cheap. They can easily be used to write information and use it in various ways. I haven't really seen NFC tags in our stores, but they are really cheap.

3. Google Cardboard

Google Cardboard is a phone holder with special prescription lenses that create a sense of virtual reality, something like the Oculus rift just when you use the phone. You can read more about what Google Cardboard is on the Internet, and you can buy it on the Aliexpress site for a few dollars.

4. USB Bluetooth Music Receiver

Turn any speakers into Bluetooth speakers! Play songs from your phone (or other Bluetooth devices) and listen to music on the speaker at the other end of the room. If your speaker does not have a USB, you can connect it with a regular 3.5mm Jack cable but you need a USB power supply for the Receiver.

5. Play music from your phone on a tape deck

This cassette works by plugging a 3.5mm jack into the headphone jack on a device, e.g. phone, and inserting the tape itself into the device that reads the tape. Play music, press Play on your device and that's it! Great addition if your car radio only supports cassettes.

6. Shooting shutter (for smartphones)

Anyone involved in photography is sure to use a trigger to take a photo from a distance. A very useful thing. For just a few dollars you can buy a trigger for smartphones, so you can take group pictures with the rear camera with a simple click of a button.
