- Mount smaller components first; largest last.
- For polarized components (e.g., LEDs, ICs, tantalum
capacitors, etc.), the convention is the negative lead goes
in the square hole.
- LEDs: shorter lead is negative. This goes in the square
hole.
- Capacitors. Usually the + lead is marked. This would go
in the round hole.
- ICs. Pin one (the notch) goes in the square hole.
- PNP transistors are 2N3906.
- NPN transistor is 2N2222.
- For the 5v regulator (labeled 78L05), a LM2931Z-5.0 will also
work.
- PWR LED is red, PGM LED is yellow, SER LED is bi-color
red/green (looks clear).
- Resistor packs are non-polarized (doesn't matter which way
they go), but don't mix up the 1K (labeled 103) and the 10K
(labeled 104). Make sure to use the isolated (pack of 5) and not
the common-lead (pack of 9) type. The isolated type is usually
labeled with a "V".
- For the power adapter, you MUST use a 12v, 500 mA, center
negative, DC adapter. A popular model of this sort is the Panasonic
KXA11. If you use a different adapter, the programming voltage on the
PIC might be too high and cause damage!
