ExoSynk is a virtual electronics lab for students, makers, teachers and engineers. The Circuit Editor runs DC and transient simulation (Modified Nodal Analysis), lights LEDs, burns them out, and lets you probe with a multimeter and an oscilloscope. It is being relaunched step by step: the Circuit Editor and Signal are open now; the 3D Editor, public repositories, tutorials and ordering come back one at a time.
Questions, bug reports and ideas. Every Signal post tagged #exosynk shows up here, and posts from here also appear in the Signal feed.
