| | A Two-into-one Homemade Neon Dimmer |
 | | With my first dimmer lying in smoldering ruin on the bench, there was not much left to do but scrap it out forparts, the most useful being the still good triac, Q1. |
 | | Miscellaneous notes: the triacs used in dimmers seem to be internally insulated from their mounting tabs, allowing them to bedirectly attached to the (grounded) dimmer frame. |
 | | In my dimmer, R1 was 250 ohms, C1 was 0.l uf, C2 (keeps line noise from false-triggering triac Ql) was 0.047 uf, L1 (value unknown, came with dimmer) helps keep switching noise from leaving the dimmer. |
