Node Assassin :: NA v1.1.4 |
This version of the Node Assassin hardware implements an 8-bit bus to get the internal port count up high to support 3 channels per node (power button, reset button and power source).
Part List
- 1x Arduino: Duemilanova
- 1x Network Shield: Assembled
- 1x Protoboard: Lab-Easy PADS-4 (or equivalent)
- 3x Optoisolators: LTV-846 (4 circuits/chip)
- 1x Inverter: 74HC540 (8-channel high-power; drives 8x 10mA LED)
- 1x Buffer: 74HC541 (8-channel high-power; drives 8x 10mA LED)
- 1x OR-Gate: 74HC32 (Quad OR Gate)
- 8x Diode: 1N4148 (Diode)
Either:
- 4x Green LEDs (max 10mA)
- 4x Red LEDs (max 10mA)
OR (harder to find)
- 4x Bicolour LEDs: 350-1839-ND (Bicolour Red/Green, 2x1 stack, common cathode, max 10mA/colour)
