This is an incredible build by YouTuber BrendaEM. Even if you don’t watch the entire explanation of the electronics and circuits encased inside the cabinet, the first few minutes are a joy to hear BrendaEM describe the amount of parts upcyclced to assemble this thing. From an oscilloscope knob to reclaimed whiteboard and plywood from a nearby community center, to the speakers themselves (otherwise left on a friend’s porch for two years!). This shows what is possible with all those spare parts you have laying around – set yourself a goal and get makin’! And if you do stick around to watch the entire video which includes an explanation of the back panel electronics you will likely pick up a few pointers and tips should you want to build something similar yourself!
This is a look at my homemade 50 Watt (25-Watt by 2-channel) guitar amplifier. It is LiFePO5 battery-powered. It runs for hours at levels loud enough to overcome traffic noise, and then some.
Many of the amplifier case parts were reused materials. The amp has given 2 years of harsh service.
Warning: you should only attempt building such an amplifier if you have good electrical/electronics practices, are quite familiar with lithium-based (LiFePO2) rechargeable battery safety, and have used the right battery for the right application, use a battery manager, have installed fuse(es), and provide for proper cooling. If you build such and amplifier, you do so at your own risk.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
