| Amplifer Wattage Question Here are a couple a simple-to-built LED audio output meter schematics. Easily fast enough to register peaks. They're limited to 10 power levels, and won't give you fine measurements though. (http://freecircuitdiagram.com/2008/09/13/audio-power-met... | |
| Why Rhodium? Some may consider Rhodium an, "excellent" conductor of electricity, but- to what are they comparing it? Silver's conductivity is 106, Gold's- 65 and platinum is 15 on the Electrical Conductivity chart(copper is considered the reference at 100). Rh... | |
