In the case of an apocalyptic event, and you don’t have an amplifier because Immortan Joe took all the amplifiers, then you need to know how to build yourself an amplifier!
In this Instructable, I’ll guide you through the process of constructing an amplifier from scrap components, and show you where you can salvage the material you need.
This amplifier can be powered by a 9V battery or DC power, and the size of it makes it a wonderful travel amp.
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.
