Joule Thief: LS GhostLight TK Remix 4: Weird Tranny
The RockyHorror weird transistor failure mode. Let’s do the Time Warp again…… ———————————- Parts List: Q1 MPSA18 or 2n2222 – 2n2222 demonstrated here, MPSA18 better for low voltage Q2 2n3055 Resistors 2 ea @ 220K 1/4W Reservoir capacitor 10000uF 16V electrolytic Transformer random from TV set chassis or roll your own on ferrite rod or E-core Weirdness capacitor 1.0 uF poly film LED green here, but bright white preferred (all mine are blown) S1 SPST S2 SPDT center off Diode MUR1560 ultrafast high current —————————- It’s not simply shorted, I tried removing it and shorting the socket pins with jumpers and nothing happened except a blip of light and high current drain. Opinions welcome, as long as they are informed by facts….. In a later video I’ll try to show the low-current behaviour. I am not happy with inline measurements of this system using that LCheepo (tm TKLabs) multimeter, though.
