At work we have a lab setup, complete with serial console access to a variety of appliances. This console access was provided through an old console server, which was FULL of problems. The biggest thing was just a lack of connectivity. Since moving, we have replaced those old console servers and denied access to the lab to most peoiple, so this setup has been rendered unnecessary. But I have an old IP Appliance sitting at home, which I have been wanting to tinker with, and it has a serial console connector, and the computer I have set up does not. So now I am revisiting the RasPi Serial Client to get it going at home, and serve as a bit of a console server (even though there is only 1 serial connection). Read on to see how I went about accomplishing this.

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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
The linked article even states that the raspberry pi costs $35, so exactly how to the additional required parts cost $0.
