It's an arc welder. 🧰
With the LED probes being the arc weldings probes and then using the lamp/ground point at the end to represent the piece of metal getting welded. ⚡💥
It will give a "Solution Error" after several pulse cycles in a row. The likely culprits are the four capacitors dumping into each of the two LEDs which then dump into the lamp through the NO button trigger. It's not so much a build flaw as much as a chain reaction that makes the simulator say "Duh...." 😏
Something about recursive logic simulators don't like, almost like asking them to go high speed down a Möbius track to resolution ⚖️
Comments always appreciated 👽
