The best thing about the Raspberry Pi is that, besides being an excellent educational device, it can double up as a very capable headless server – now even more so with the increased memory.
Contrary to popular belief, not every server task requires lots of processing power. For example, if you wish to download files and share them with users on the network irrespective of their operating system or device, you don’t need a machine with a multi-core processor. In fact, using an old Linux computer as such a seedbox is a popular way of rescuing discarded hardware.
The only downside of this approach is that it consumes a lot of electricity. Most modern routers have a USB port, and will share the plugged-in device with all computers connected to this router. But what if you have an older router and want to do more than just share files?
With the RPi, you can do all this and a lot more without the costs associated with a traditional computer, and without the restrictions of dedicated devices such as routers.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
