The KISS-102 Selective Solder machine contains a pot of molten solder which must be regularly cleaned. In the video you can see “dross”, a layer of scum formed from oxides and other debris, being scraped off the surface of the pool of molten solder. This machine is an essential component of Adafruit’s manufacturing line, and one that requires consistent attention. We clean this machine before and after every use to make sure it’s always in top notch soldering condition.
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.
