What Is the Raspberry Pi?
No, it’s not a tasty dessert. The Raspberry Pi is the smallest, cheapest, most fun computer you can own. Tech Talker explains more about the raspberry Pi.
In the past few months, many of you have sent me questions about the Raspberry Pi. So in today’s episode, that’s exactly what I’ll be covering – the amazing Raspberry Pi! No, I’m not referring to a delicious desert, rather a miniature computer that is about the size of a credit card. You’re probably thinking, how the heck can a computer be that tiny, or for that matter what would you even do with a computer that small?
Let’s find out!

What Is the Raspberry Pi?
The Raspberry Pi was created with the goal of education in mind. This ultra-tiny computer was designed to be small and cheap so that schools could easily afford them in order to teach students about computers in the classroom. This is great for two reasons, the first is that it provides extremely cheap access to a computer, and second it is a great tool for learning more about computers (student or not)!
So how cheap are we talking exactly? Well, there are two versions of the Raspberry Pi, the model A is $25 and the model B is $35. This price point makes it pretty easily available to students, hobbyists, and even yours truly!
Let’s talk about what the Raspberry Pi has on it. In the model B, you get an HDMI out, RCA video out, 2 USB ports, an SD card slot, a head phone jack, and an Ethernet port. The board itself has half a gigabyte of RAM and an onboard ARM processor.
The model A has all of the same features of the model B minus one of the USB plugs, the Ethernet port, and half of the RAM.
No matter how you look at it though, it gives you quite a bit of equipment to work with for not being much bigger than a credit card!
How Does the Raspberry Pi Work?
Here’s how it works: An SD card inserted into the slot on the board acts as the hard drive for the Raspberry Pi. It is powered by USB and the video output can be hooked up to a traditional RCA TV set, a more modern monitor, or even a TV using the HDMI port. This gives you all of the basic abilities of a normal computer. It also has an extremely low power consumption of about 3 watts. To put this power consumption in perspective, you could run over 30 Raspberry Pi’s in place of a standard light bulb!
So far we’ve covered what the Raspberry Pi is and what features it comes with. But what can you actually do with such a little computer?
The answer is a ton! Some of my favorite projects are creating wireless home speakers, a media center for my TV, and even a personal web server! These projects are driven by the free operating system you can download for the Raspberry Pi called Raspbian. This operating system is a lightweight version of Linux that is optimized for this low powered device.
Each of these projects requires some work to set up, but they’re a perfect way to get your feet wet with computer programming and operation.
The last thing I want to mention about the Raspberry Pi is the community. This is probably the greatest feature of the Raspberry Pi, but probably one of the least talked about. The community that uses the Raspberry Pi is the most helpful one that I have seen across the tech spectrum. One of the perks of the educational aspect of this device is that every project someone does with it is extremely well documented with step-by-step instructions and often includes pictures. The forums for the community span many counties and every level of expertise.
With that, here are your Quick and Dirty Tips for getting to know Raspberry Pi:
The Raspberry Pi is an inexpensive and miniature computer.
It was developed as an educational tool, and has been made available to everyone, no matter your computer expertise (or lack thereof).
The Raspberry Pi is a versatile computer that can be made into just about anything.
If you’ve been wanting an inexpensive way to get into programming and DIY tech projects, this is an awesome place to start!
