Assembly:
If you purchased our kit, refer to the parts list and make sure you have all of the components you need to build the kit.
Click here for Parts List.

Assembly can be done by personal choice, but you may find it easier to build in vertical height order by installing the shorter components first, followed by the taller ones.   Kits are shippied with presoldered surface mount parts, and cleaned free of any flux residue.

Install all resistors.  Some resistors colors may look 'off'.   If in doubt, use an ohm meter to verify the value before soldering it in place.

Install the diode and shorter capacitors, observing polarity. The square pad is the banded end of the diode. Small capacitors are identified as follows: "474 = .47 uF, "124" = 0.12uF, in other words the first two digits are the value and the third digit is the number of zeroes you add to determine the value.

Then install the LED (short lead to the square hole).

Then install the transistors (flat to flat on silkscreen).  Install the 6-position DIP switch.  See photo for DIP switch package orientation.  The word "ON" goes towards the DB25 connector.

Next - install the voltage regulator IC.

Install the larger capacitiors. The + of the electrolytic capacitors go into the square holes. The metalized film capacitors can be installed either way.

Next - install and the three pin and two pin headers, followed by the DB25F.
