By default, the Raspberry Pi is used like a computer, where you need a keyboard, mouse and monitor. Here are some other ways to configure it.
The Raspberry Pi is a wonderful, inexpensive computer useful for hobbyists, classrooms and professionals.
Unfortunately, if you follow most “getting started” guides, the first thing they tell you to do is connect a keyboard, mouse and monitor, which can easily double the cost of your Pi setup.
I remember being at a hackathon where attendees were given Raspberry Pis to hack on. With only their laptops, there was no easy way for them to interact with the little computers. Luckily, Kassandra and I were able to pull together a monitor, keyboard and mouse to help configure each Pi so that users could log into them remotely. That took a while.
I’m sure there were other ways to go about configuring the Pi, but under the time constraints, that’s all we knew. In the hopes of preventing a similar situation, I’ve put together a couple tutorials that talk about how to configure your Pi as a headless computer (“headless” meaning without a keyboard, mouse or monitor). I hope they save some fellow hackers some frustration in the future.
There are a number of ways to configure a Raspberry Pi without needing to connect a monitor, keyboard or mouse. They all have their pros and cons. Most of the time, you need some additional hardware, such as a USB-to-serial converter or an Ethernet cable. In this tutorial, we look at three different ways to create a headless Pi installation:
For me, I usually opt for the serial terminal option, since that seems to always work. I guess the moral of the story is that I should never leave home without a USB-to-serial adapter.
Once you have the Raspberry Pi set up (headless or not), you can configure it to act as a WiFi access point. This will allow you to connect other devices to your Pi, should you want to host a local web site or share drive space. You can even connect the Pi to another network over Ethernet. This will allow you to share internet with the wireless devices and, in effect, have it act as a router.
Do you have any other tips for setting up your Raspberry Pi as a headless device, or fun projects you’ve created using it that did not require a monitor?
