Introduction
WordClock-1 assembly should be attempted only by experienced builders. Although assembly
is straightforward and not difficult, there are several SMD parts that must be carefully
soldered to the boards. The kit may be returned for a full refund less shipping within 30 days
of purchase, only if assembly has not been started.
Assembly
WARNINGS!
DRILL HOLES IN THE CASE BASE FIRST. USE THE CIRCUIT BOARD AS A TEMPLATE.
DO NOT INSTALL THE HEADERS FOR THE ALPHANUMERIC LEDs. REMOVE THE PINS,
OTHERWISE THE BACKLIGHTING WILL BE BLOCKED.
DO NOT SOLDER THE MICROCONTROLLER DIRECTLY TO THE BOARD, USE
HEADERS.
Case
If you purchased the optional acrylic case, this would be a good time to mark and drill the
holes in the base. It is easiest to use an unpopulated circuit board for this purpose. The
precise distance between holes is 156mm wide by 34.5mm deep.
The board should not be
centered on its base because the LED displays extend beyond the front of the board.
