The clock uses a Trinket microcontroller board to keep track of the time and to send step signals to a StepStick that drives a NEMA 17 stepper motor. All of the design files are available here for anyone who wants to build one of these neat clocks. The 3D printed parts were designed by himself. Since the minute hand rotates 12 times for every one revolution of the hour hand, the gear ratio can easily be calculated. As the hour hand turns, the gear system rotates, the last gear of which is connected to the minute hand. It works because of a gear system hidden behind the thick hour hand. decided to take the minute hand and move it out to the tip of the hour hand. In a typical mechanical hand clock the minute and hour hands rotate around the same axis. has done something that is so simple, we are surprised it isn’t more common. Some make it easy to tell the time, others are more cryptic. It hopefully won’t be too long before we start seeing more of these low-cost word clock designs!Ĭontinue reading “Can You Read Me The Time?” → Posted in 3d Printer hacks, clock hacks, LED Hacks Tagged 2019 Hackaday Prize, 3D printed clock, word clock

As a low-cost solution, while there is still some amount of light diffused, it’s definitely better than without the separator.Īlmost all of the files used for building the small word clock are available on ’s project page, including the software and design files.
To tackle the light scattered internally in the PCB’s FR4 material, a separator is used to contain the light.

The time tracking is fairly simple, using a DS1302 serial real time clock chip – it even charges a super capacitor to keep time after power is removed! By skipping or not skipping cycles, this allows the display to look brighter or dimmer. For scanning the matrix, the software uses an interrupt that draws the current column of LEDs and updates the display image before incrementing to the next column. Using a pin map assigned to the I/O for the rows and columns of the array, the software toggles the states of the pins as a switch statement.
It’s a pretty understandable solution for keeping the design simple, and the letters all fit onto the design so well!

Rather than making a larger array of letters, had the clock describe the time down to five-minute intervals then add asterisks for the full time. One design challenge for the letter matrix was fitting all possible minutes into the array. In order to block light between adjacent letters, the 3D-printed light box comes into play. The bottom side uses the same design principle with a square shape that overlaps the letter. The design places the letters on the top stop and restricts layers to keep the solder mask and copper from obstructing the light. The design uses a home-brewed PCB design that runs off 5 V via USB. In fact, they were inspired by all of the existing DIY word clock designs using anything from off-the-shelf LED arrays, transparency masks and WS2812s. Unlike a similar project made by, which uses an 8 x 8 LED matrix with an inkjet printed overlay, this small word clock uses a 3D-printed light box to achieve its letter matrix. Typically, the solution is just to use a digital timepiece, but has opted to make a small word clock that you can carry with you wherever you go to remind you of the time in the English language. If you’re like the average clock user, you’ve probably gotten annoyed at reading analog clocks before.
