Wouldn't steel wool catch fire when exposed to an electric current? It might be useful to indicate there was still some charge in the capacitors, though

- Scoundreller 5y agoThat was my worry. The resistance might be too high and get too heated. The nail avoids that issue. In a power supply, you'd also have to worry about shorting and shocking other ICs with steel wool, but not with a big capacitor.
