Word clocks use natural language to display the time. They’ve been in vogue in the last 20 years or so, as low-cost digital technology makes them particularly cost effective and easy to build for the average maker. The hardware and software is a solved problem, so presentation is everything. Luckily, [watsaig]’s effort does not disappoint.
The build began with a timeframe of just seven days — a narrow window given [watsaig]’s lack of experience with lasercutting and woodworking. Not content to let that get in the way, it was time to get to work. Wood was sourced from Amazon and designs laid out, before lasercutting began in earnest.
[watsaig] decided to fill all of the letters with epoxy to achieve a flat finished surface that also served as diffuser for the LEDs. To avoid using an unsightly stencil font, the centers (the cut out portion) of letters like O, A, and R had to be placed by hand. Unfortunately his turned out quite badly. When using a squeegee method to work epoxy into the letters, the inserts tended to shift, ruining the face plate.
Undeterred, the clock face was recreated from scratch, and it was determined that a pipette was a far more suitable tool, allowing the letters to be filled with epoxy without unduly disturbing the letter inserts. The final result is visually attractive, finished with a wonderful stain and giving a pleasing glow thanks the careful attention to diffusion and masking. The hidden Happy Birthday message may have been lost in the rush, but it’s the thought that counts, after all.
