Is it important that the resistors in this circuit are 1/2 watt (except the 1 watt one)? I only have 1/4 watt - I know I can double up, but want to know if it is necessary? Thanks! |

Even if all the 6.3V were across the 560 Ohm resistor, the dissipation would be about 80 milliwatts so don't worry about it. 1/8 Watt resistors would even be okay. |

I think someone somewhere got their Ohm's Law calculations wrong for the 1K resistor too... it should be 1mW not 1W! |
