There’s plenty of obscure sports in the world. Many of them could benefit from bespoke equipment like scoring displays, but are too obscure to support commercial efforts in this regard. Radio controlled glider competitions fit into just this category. This led a man named [Mickey] to develop what he calls Mickey’s Big Timer, to aid in the running of such events.
Glider events run outdoors in full sunlight, so the system uses big bright LED matrix displays to show its timing information. The system, built around the STM32 Discovery platform, uses several of the microcontroller boards to drive several displays as well as the main controller which handles timing. It also packs in an audio system for issuing instructions to competitors. It can also display pilot names as well as instructions such as when competitors should land at the end of a heat.
Some code is available on Github for those interested in how it all works. Word around the RC forums has it that [Mickey] built several systems, some of which ended up as far afield as New Zealand where they helped run many successful glider contests over the years.
We’ve seen plenty of scoreboard projects over the years; a little portable one could be useful for adding some spice to your pickup neighbourhood games. Video after the break.

It’s that time of year in both hemispheres — time to get outside and play before it gets unbearably hot (or cold). No matter what your game, don’t keep score in your head or with piles of rocks — make yourself a portable, fold-able scoreboard like [LordGuilly] did and be on the bleeding edge of display technology. It’s really more roll-able than fold-able, which is awesome because you get to unfurl it like a boss.
All you need is a place to hang it up and you’re good to go. This thing runs on a beefy 10,000 mAH USB power bank, and [LordGuilly] says that it’s easy to read even on really sunny days. As you may have guessed, those are WS2812 strips and they are set into rectangular PVC bars. The bars are set equidistant from each other in a frame made from modified version of cable tracks — plastic chain links for cable management.
Good looks aside, we especially like that there are two controller options here. If you want to assign a dedicated scorekeeper, there’s a handled version that uses an STM32 blue pill and is wired to the display. But if you’re short on people, use the ESP8266 version and update the score with the accompanying app. Check out the demo after the break so you can see it in action.
We’ve seen a few scoreboards over the years, including this beauty that’s meant for indoor games.

Minigolf is a fun, simple pastime that has the benefit of taking up much less space than the classical game it is inspired by. [gcall1979] had built himself a small game for the lounge room, but found keeping score to be a tedious exercise. Of course, that was nothing that couldn’t be solved with some electronics!
The game consists of a skeeball-type minigolf course, where the score is determined by the hole the player puts the ball through. To track this, each hole is fitted with an IR break-beam sensor that triggers when a ball passes through. Vinyl siding is used to guide the balls going through the holes to ensure the sensor is triggered consistently. The sensors are read by an Arduino Mega, which is also responsible for flashing LEDs and updating the score throughout the game on the included 7-segment displays.
It’s a basic hack, but one that makes the game far more of a self-contained experience. No more fumbling with pencils and paper means it’s easier to focus on dominating the competition on the (miniature) green. Of course, those with dreams of the driving range might consider this recreation of the famous Floating 14th Hole!
Foosball, also known as table football, is a classic game from the 1920s that is completely devoid of the bells and whistles of modern gaming. Players control stoic little figures with the most simplistic of input devices in order to move a tiny ball to and fro on the playing field. So naturally, somebody thought they should add a Raspberry Pi to it and drag the whole thing kicking and screaming into the 21st century.
The team at [Matmi] spend a good portion of their down time huddled over a foosball table, but they found the experience was significantly less exciting for the spectators than the players. To add a little more pomp to their sessions they added a flashy display that not only shows the current score, but makes individual scores a bit more exciting by showing some celebratory confetti.
Micro switches mounted in the ball return tubes of the table allow the Raspberry Pi to know who scored and when. This information is picked up by the web-based scoreboard written in Vue.js and served out by nginx. The actual scoreboard is being displayed by a laptop that’s connected to the Pi over Wi-Fi.
If the software setup seems a bit convoluted, it’s because the project itself was something of a learning experience for HTML5 and web programming in general. Further updates are planned to streamline the system a bit to make it more self-contained, as well as adding more features to the scoreboard such as tournaments and randomized matches.
Interestingly, we’ve seen quite a few foosball hacks over the years. It seems these tables are somewhat ubiquitous in offices and hackerspaces. From turning it into an online-enabled experience to building an AI table you can play against, there’s plenty of ways to inject some new life into this nearly 100-year-old game.

The game of cricket boggles most Americans in the same way our football perplexes the rest of the world. We won’t even pretend to understand what a “wicket” or an “over” is, but apparently it’s important enough to keep track of that so an English cricket club decided to build their own electronic scoreboard for their – pitch? Field? Help us out here.
This scoreboard build was undertaken by what team member [Ian] refers to as some “middle-aged blokes from Gloucestershire” with no previous electronics experience. That’s tough enough to deal with, but add to it virtually no budget, a huge physical size for the board, exposure to the elements, and a publicly visible project where failure would be embarrassingly obvious, and this was indeed an intimidating project to even consider. Yet despite the handicaps, they came up with a great rig, with a laser-cut acrylic cover for a professional look. A Raspberry Pi runs the LED segments and allows WiFi connections from a laptop or phone in the stands. They’ve even recently upgraded to solar power for the system.
And we’ll toot our own horn here, since this build was inspired at least in part by a Hackaday post. The builders have a long list of other links that inspired or instructed them, and we think that says something powerful about the hacker community that we’ve all been building – a group with no previous experience manages a major build with the guidance of seasoned hackers. That’s something to feel good about.
There’s a great game of capture-the-flag that takes place every year at HITCON. This isn’t your childhood neighborhood’s capture-the-flag in the woods with real flags, though. In this game the flags are on secured servers and it’s the other team’s mission to break into the servers in whatever way they can to capture the flag. This year, though, the creators of the game devised a new scoreboard for keeping track of the game: a lightsaber.
In this particular game, each team has a server that they have to defend. At the same time, each team attempts to gain access to the other’s server. This project uses a lightsaber stand that turns the lightsabers into scoreboards for the competition at the 2015 Hacks In Taiwan Conference. It uses a cheap OpenWRT Linux Wi-Fi/Ethernet development board, LinkIt Smart 7688 which communicates with a server. Whenever a point is scored, the lightsaber illuminates and a sound effect is played. The lightsabers themselves are sourced from a Taiwanese lightsabersmith and are impressive pieces of technology on their own. As a bonus the teams will get to take them home with them.
While we doubt that this is more forced product integration advertisement from Disney, it certainly fits in with the theme of the game. Capture-the-flag contests like this are great ways to learn about cyber security and how to defend your own equipment from real-world attacks. There are other games going on all around the world if you’re looking to get in on the action.

[Kratz] is working on a WiFi controlled scoreboard, but before building the full-scale version, he thought it would be wise to test out the multiplexing technique for the display. The experiment worked, but unless this scoreboard is for a foosball table, he still has a lot of work ahead of him.
The design of this prototype display is pretty simple, with just two ‘595 shift registers feeding bits to the display. Sixteen NPN transistors are being used to sink and source current to the display. It’s a relatively simple circuit, allowing [Kratz] to fit nine seven-segment displays on a small board with only six wires – ground, two V+ for the logic and LEDs, clock, data, and latch – going to the microcontroller.
There were a few snags in the design; the data is clocked in on a rising edge, but an extra falling edge was required before latching. [Kratz] can’t figure out the reason for this, and it might just be a timing issue.
