- * circuit - Random electronic components floating around
- *
- * version 1.4
- *
- * Since version 1.1: added to-220 transistor, added fuse
- * Since version 1.2: random display digits, LED improvements (flickering)
- * Since version 1.3: ICs look better, font textures, improved normals to
- * eliminate segmenting on curved surfaces, speedups
- * Since version 1.4: Added RCA connector, 3.5mm connector, slide switch,
- * surface mount, to-92 markings. Fixed ~5min crash.
- * Better LED illumination. Other minor changes.
