Now if you were to get in a bind and needed to run a car radio tape player off 12 volt power in the house you would need this stuff.
I was in that bind and at the young poor age of 13 I did it. I took a 6 amp 12 volt car battery charger and hooked it up. What the devil is that buzzing noise? ![]() Well it was that dreaded AC ripple I talked about. That buzz was unfiltered DC current the buzz is the polarity swapping 60 times a second. Now how to filter it out. I took a dead cant charge anymore car battery and ran my charger to it. And then to the tape player. This killed out all of the AC ripple and in effect I had a filter as a battery and capacitor which is used for a filter are a lot alike. ![]() Yes I had a lot of crazy stuff in my room growing up. Dried bugs and critter collections pet frogs strange mold experiments and electrical stuff and occasional controlled explosions and fires. ![]() Worth Wiring 4.jpg |
