Little Shop of Physics has built a miniature plasma cutter using a pencil lead together with 4 x 9 volt batteries and a couple of clips allowing you to cut through aluminium foil.
Learn more about how to create your very own plasma cutter and how it can be used to cut thin metal foil using a mechanical lead pencil, Watch the video below.
Parts required to make your own include :
– 4 x 9 V battery
– 2 x Clip leads
– 1 x 5 mm pencil lead
– Aluminium foil
– Box or tub
– Rubber band
This demonstration is only for the experienced! Little Shop of Physics took several precautions to do this demonstration safely. Don’t try this yourself unless you understand and appreciate the difficulties and the dangers.
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.
