cheap electronics - 15 electronics projects under $15 - diy electronics - wireless electric toothbrush

Profile I recently released a hub listing some good projects that are interested in electronics that have just started.
If this is you, or if you just want ideas for something fairly simple, usually fun, and sometimes useful, then be sure to take a look at it other than this page.
None of the lists are particularly expensive.
However, if you really don't have a lot of money to spend, then I 've put together a list of items under $15!
While most projects are fairly basic, I wouldn't say that these are items that are suitable for beginners.
15 projects under $15 are hard to give the exact amount for many projects, but I will do my best to provide a reasonable estimate.
To find the items listed, just search the website where they are located: instructures portable guitar amp ~ $10 didn't you always want to put a guitar amp in the bathtub? I know I have.
Well, maybe I didn't think about it before I found this project, though, it's a really cool idea, for some budding musicians, there is a portable guitar amp that could even be used! -
This project is in structure.
At the end of the day, of course, it's actually just a program launcher, though you can modify it to do many different things.
Very sweet looking device, very cheap for doomsday devices!
There is a worrying idea now. -

Chapstick LED flashlight ~ $7 simple design and easy to make.
If you have a reason to hide the torch, then a stick may be the perfect disguise! -

I know it was made with a toothbrush, but I don't recommend putting this animal in your mouth!
Of course, this is not the real purpose, but who says that everything should have a practical purpose? ? -
This project is in structure.
This is probably my favorite item in this list.
Have your own mechanical pet, no, I'm not referring to those stupid high-priced robot toy dogs or something like that.
Of course, this may not change, although you can definitely find a way, but the project has a certain attraction to it, the only word I can think of is "cute ", at least for an electronic project.
Anyway, you will understand what I mean when you look at it. . .
Or you might find it a little weird that I call it cute. ' -

$5-LED pain$15 (
Depending on how much you want to do
Probably the most colorful item on the list.

Coke thief ~ $3 this project will drain the last bit of energy from the battery you think is completely dead!

LED jelly ~ $6-
The $15 "circuit" is basically the LED Throwies circuit, but the purpose of this time is to make jellyfish!

Super capacitor USB Light ~ The $7 super capacitor is a fairly interesting component and worth a look if you are interested in this theory.
This is a very simple app but still cool. -

Vibrobot ~ $10 I think the description on structure best describes this: "An easy way to delight a simple mind. . .
Or a complicated person who needs a break, it's fun for most people ", a simple vibrating motor that takes out of cheap electric toothbrushes and ties them to altids tin, though, I assure you that it will provide you with some form of entertainment, if not. . .
Then do something different with your imagination! -

$4 USB latte what can I say? Maybe, genius? No, not really.
Still very novel!
If you're tired of wasting batteries on cheap latte frothers you got from your distant relatives last Christmas, then this could be your perfect solution!
It is very likely that when you drink coffee, you will be near the USB port, and fortunately, the USB port is actually connected to or integrated into some kind of device that provides power. . .
Like a computer or laptop. . .
If so, you can use this project to power your latte frother! -

LED cubic night light ~ $5 simple but effective!

You may have heard of this fruit clock or potato clock.
The advantage of the fruit clock is that it does not rot. . .
Soon, it looks much better!
Anyway, with this item, you can say goodbye to the traditional battery of the alarm clock and say hello to those bright orange Juicy battery types. . .
Or yellow, green. . .
Maybe the fruit of your choice is red or any color! -

Let Beetlebot ~ For $10 a set to put one at home, your cat might think it's a mouse and go crazy, but I'm sure once you calmly explain to the cat that it's impersonating Belte, it will stop chasing it. -
This project is making a cookie box Amp similar to the last portable guitar Amp ~ $5, just cheaper shell for this project! -
The project is under production.
