There are many versions of the symbol for each component in electronics. Below I’ve listed the ones I’m using the most.
You see, I got a drone for Christmas this year.
It was really windy outside that day. However, I was so excited to take it for a spin!
I found a big open space, put my drone down on the ground, and started the take-off.
I only got the drone a couple of meters up into the air before the wind took charge. It blew it further and further away from me until it crashed into a tree and fell onto the ground.
This didn’t stop me though. I started over again.
But the same thing happened. It was impossible to control the drone in the strong wind!
After maybe ten crashes, one of the rotors stopped working!
I hoped it was just a flat battery, but it was not.
Imagine a beautiful summer day. You’re on you way to meet friends for a picnic in the park. But, the park is huge and full of people. Since you don’t know where exactly your friends are, you pick up your phone to call them.
But as you dial the number, the battery on your phone dies…
With this portable USB charger circuit, there’s no need to worry. Just drop by a supermarket nearby and pick up some standard batteries to recharge your phone on-the-go.
Even though you can do a lot with just a soldering iron, getting a few extra tools might things easier.
In this articles I’ll show you what the basic soldering tools are.
My workday is coming to an end here in Australia.
And tomorrow is Christmas Eve.
Now I just need to get those last Christmas presents taken care of.
If you’re like me, waiting until the last minute, how about giving the gift of knowledge this year?
Electronics is not only a fun hobby, it’s knowledge that is useful in the workplace, at schools, and for budding entrepreneurs.
For example: Want to automatically turn on a light when it gets dark? The PNP transistor will make this easy for you.
In my article how transistors work, I explained how a standard NPN transistor works. If you haven’t already, I’d really urge you to read that article first.
If you understand the NPN transistor, it will make it easier to understand the PNP transistor. They work pretty much in the same way, with one major difference: The currents in the PNP transistor flow in the opposite directions of the currents in the NPN transistor.
What do you buy for Christmas for someone who’s interested in electronics? Check out these Christmas gift ideas and get the shopping over with.
Last year I received three boxes with a lot of resistors and capacitors from my family. And I absolutely loved it!
I guess a box of resistors and capacitors isn’t everyone’s cup of tea…
Instead, here are some Christmas gift ideas from me that I think every electronics-interested kid, adult or grandparent would love.
This circuit is easy to build and it’s something you can put to use right away. I built this and hung it in the window, something my girlfriend loved!
The blinking part of the circuit is made up of only 4 components. Then you’ll add as many lights as you want.
There’s some confusion going on when it comes to how to choose a power supply.
So, I thought I’d clear up some doubts, and give you a simple, beginner-friendly way of choosing a power supply.
Let’s start with the basics. A power supply has a voltage and a current specification:
- The voltage is the output voltage from the power supply.
- The current is the maximum current that the power supply can give.
