I finally finished my Table Tennis Scoreboard: I thought this would be a good place to show it off. The display itself can be mounted to a wall, a tripod, or just sit on a tabletop. It can be battery or wall-powered. The 7-segment numbers are pretty bright, and should be suitable for any indoor environment unless it is completely flooded with light. The buttons are wireless, and can be mounted under the table tennis table (ideally right in the center of each side). They run off a coin cell and the battery should lasts about 5+ years. My set is 2 years old now, and still going strong. I documented in great detail how to build one: https://www.instructables.com/id/Table-Tennis-Scoreboard/" rel="nofollow - https://www.instructables.com/id/Table-Tennis-Scoreboard/ I also have a lot more photos and info on my website: http://rapidwhale.com/scoreboard.php" rel="nofollow - http://rapidwhale.com/scoreboard.php Thanks for checkin' it out. -Josh!

Awesome! Does it automatically swap the scores (and colors) when changing sides after each game? If so, can this be bypassed in case we decide to stay put? Also, can it be programmed for best out of 5-games and 7-games? How about games to 21? Anyway, great job !!! . |

Nicely done! It will be great if the front casing is black / dark. Because display numbers and scores will look contrast and clear. Whether the pointer arrow will automatically move to the opposite position when serve over? ------------- TB ZLC + T05 + O7E Link Feedbacks To Me : http://mytabletennis.net/forum/feedback-antsj00_topic84038_post1041973.html?KW=" rel="nofollow - Feedbacks |

This is the only non-option (as currently programmed) of all your other questions. I decided to apply official table tennis rules to the code, such that after each game you switch sides, and at the match-point game (or whatever you call the absolute last possible game) you switch sides at the approximate half-way point throughout the game. These rules exist such that both players get equal play time on either side of the table. Thanks for diggin' it. -Josh!

I actually built one in black, and funny enough, it was actually harder to read. On white, the score was easier to read, and is of better contrast and brightness than in photographs. On account of it being very hard to simulate the same brightness/contrast in a photo (even with a lot of photoshop work). The reason the white ended up being the better choice is because it is of a more similar color to the textured semi-clear acrylic that makes up each of the segments in the 7-segment displays. The only color choice better than white would have been a slightly off-white grey, which unfortunately isn't a readily available acrylic color-choice for me. So white it was. |

Obviously, your product is superior and most every club would want one. I just wanted to present an alternative to a small club with small budget. ------------- Hntr Fl / 4H & BH Xiom Sigma Pro 2 2.0 Yinhe T-2 / 4H Xiom Sig Pro 2 2.0 BH Xiom Omega IV Elite Max Gam DC / 4H DHS Hurricane 8 39deg 2.1 BH GD CC LP OX HARDBAT / Hock 3 ply / Frenshp Dr Evil OX |
