incandescent light flicker hacks

there are 2 hacks with incandescent lights that make flickering effect. may be usefull for some haloween stuff here is the most basic description. if you build it be carefull in fire safety - some stuff may overheat and blast / catch fire. use non flammable boxes if needed. starters and diodes may explode if connected incorrectly - always protect your eyes do not do any of the hacks with CFLs - they are for incandescents only. they may work with LED lights depending on other components in the ciruit and the amount of current (if there are capacitor / induction / electronics / transformer in the LED circuit then dont do it) hack 1 - slow flicker (i saw it somewhere on instructables before) connect the incan in series with fluorescent lamp starter (the neon discharge type) you may connect 2 starters in series. i'd expect longer outages this way. if they dont light (not enough voltage) then use the starters designed for 2 x 18 W fluorescents. warnings dont connect the starter (or series of 2 or more starters) directly across the ac source. the starters will blow immediately and may explode. check that in any possible path through the starters there is an incan light dont connect stuff in parallel unless you really know what you do. lights connected in parallel take the sum of the currents they take on their own - anything more than 1 light is too much for a starter (or any amount of starters in series - each gets all the current) part 2 - fast 50 Hz flicker connect the lamp in series with an 1N4007 diode. the diode blocks 1/2 of the ac wave and makes some light flicker. seen best in low watt lamps with thinner filament (with less thermal capacity) diode may be used together with starter to combine the effects this hack is used widely in heating appliances that have 2 heat settings. in the lower one they are connected thru a diode
