Introduction
WordClock-3 assembly should be attempted only by experienced builders. Although assembly
is straightforward and not difficult for experienced kit builders, there are several surface mount
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 attempted.
IV-17 TUBES ARE NOT INCLUDED IN THIS KIT.
Assembly
WARNINGS!
DRILL HOLES IN THE CASE BASE FIRST. USE THE CIRCUIT BOARD AS A TEMPLATE.
DO NOT SOLDER THE MICROCONTROLLER DIRECTLY TO THE BOARD, USE
HEADERS.
USE A GOOD QUALITY, UL LISTED, 12V POWER SUPPLY.
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 205mm wide by 68mm deep.
