Key components

10K resistor - Brown, Black, Orange, Gold = 1 (Brown) 0 (Black) x 10^3 (Orange) +/-5%. Cheatsheet.

105 monolithic capacitor - 10^5 pF = 1,000,000 pF = 1,000 nF = 1uF

BD243 Transistor

Using Eagle - let's draw the schematic.

1. Start with the input connector (we can assume a 12Vdc battery/power source is connected to input).

Use a Sharpie to identify the nodes/components that you traced.
