The schematic and board files are available here.ġ6 PNP transistors (2N5401) are used for driving (supplying current to) the LED columns. J1, J2, J3 - Use any ONE of these three locations for Power In connector (USB-b) The following parts are not provided (they are not required):Ĭ11, C12 - 22nF (not used if X1 is a resonator, USED if X1 is a Crystal) Try not to damage traces in the process, otherwise you will need to replace them with wires (a bit ugly, but still functional).
Use a solder sucker or, even better (cleaner, easier), de-soldering braid, to remove the solder and pull the piece gingerly while applying heat. Check (I use a magnifier glass) that the solder does not short neighboring parts. If it doesn't look good, try re-heating the joint until the plated-through-hole sucks up the solder. On the front, you should see that the solder came all the way trough the board. On the back, the solder should be shiny and make a volcano shape, as opposed to a dome shape. After each step, evaluate the solder joints from the front and back of the board. Make it a goal that you will not have to de-solder in the course of making this clock.
While de-soldering is possible, it is troublesome and time consuming and risky. Double and triple check that the part is in the correct place with the correct orientation (where applicable). If this is your first project in a while, here is a quick refresher on soldering. If it is, we'd suggest getting a cheap learn-to-solder kit to get started. We assume that this is NOT your first soldering project. This protects the parts from scratching and smudging. Leave the paper on the front cover and front frame until final assembly. You will have this clock for years to come (and hand it down to your grandchildren!) so there are no worries if it takes you an extra day or week to build it.ģ. Enjoy the build process and take a break when you feel fatigued. We've captured all of the mistakes and blunders made in creating and building the prototypes and tried to foresee problems you may have.Ģ. It could save you hours of rework and much consternation. I know, they always say that, but heed the advice this time.
Read through and understand the entire set of instructions before you get started. soldering, browse through this list of tips:ġ. at 25cm x 25 cm, big enough to hang on a wall, yet small enough to stand on a desk. current functionality also includes alarm (with the on-board buzzer), time and date setting from buttons features a matrix of 16 x 8, individually addressable LEDs, which also allows the display of patterns/bitmaps/digits/scrolling text uses the extremely accurate, temperature compensated, DS3231 real time clock chip, with backup battery Arduino (ATmega328) compatible, hackable/programmable using the Arduino IDE Here are a few characteristics and "specs": You will end up with a beautiful and solid word clock, as shown in the photo below.
#Diy word clock how to
This instructable shows how to assemble the C3Jr kit. This kit is the result of countless hours of design, engineering, prototyping and programming by the talented Wyolum team (which also brought you ClockTHREE, the only multi-color word clock).
#Diy word clock professional
What makes it stand out among the DIY word clocks is, beside the professional look, its engineering: its dabble-free approach requires no more drilling holes for the LEDs, no more scissor-cutting cardboard to separate blocks of letters, no more soldering cables and terminals in the air.Ĭ3Jr comes as a kit that includes a large PCB, electronic components, a set of high intensity diffused LEDs and mechanical parts (back and front plates, baffles etc).
