LED Robot Soldering Kit, Solder Included - Free-running Oscillator Project (Beginner Skill Level) which are small electronic resistors

which are small electronic resistors made out of metals that conduct electricity within a certain range and become more conductive the warmer they get

This "A" model features additional wave tracking

Edges are beveled to reduce snagging

but the additional wave tracking

The PSU's internal memory can store up to four sets of front-panel settings for future recall
