All connected
6 key parts, one program, and your phone
What it is
One pitch-side hub with goal cameras, a heading pod and two e-paper boards, with one club app.
What it does
Who it's for
Youth football clubs that train and play on their own pitch.
How the parts connect
Every part, what links it to the brain, and how the data reaches your phone. A solid line is a cable; a dashed line is a radio link.
The program
const clock = new MatchClock(); // kick-off, pauses, half-time
const bins = new SinBinEngine({ periodMin: league.sinBinMin });
const quarters = new QuarterEngine({ rule: league.quarterRule });
mqtt.on('board/+/key', (k) => bins.handle(k, clock.now())); // HOME / AWAY presses
mqtt.on('coach/+/lineup', (l) => quarters.lock(l, clock.quarter()));
hailo.on('shot', (s) => clips.save({ ...s, minute: clock.minute(), down: bins.active() }));
setInterval(() => {
mqtt.publish('board/sinbin/screen', bins.screen(clock.now()));
mqtt.publish('board/quarter/screen', quarters.screen());
}, 10_000);To your phone
Coach tablet; referee and parent phones
One screen for each job GoalSide does.
ShotsAt Tuesday training the U14s shoot at goal. The post cameras log each shot zone, result and speed, with a clip for the coach.
Header countBefore a heading drill, each player taps a wristband on the pod. The ring shows how many headers they have left this week.
Sin binOn match day the referee sends AWAY #7 to the sin bin and taps AWAY at the restart. The halfway board counts down his time.
QuartersCoaches send each quarter lineup. Before Q4 the board shows who has played least, so everyone gets their turn.
App screens with sample data. The interface is in development.
| Shot | Top left, goal, 71 km/h (±10%), clip c_412 | Each shot |
|---|---|---|
| Headers | Sam (U14): 7 of 10 this week | Each heading turn |
| Sin bin | AWAY #7: 3:40 left | Every 10 s while a player is out |
| Quarters | #4 and #11 must start Q4 | Each quarter |
| Match goal clip | 31:40, AWAY down to 10 | Each goal |
Players are first names or shirt numbers only. Clips go to parents only after the club approves. Sin-bin and quarter records stay with the club and the referee's report.

From the product lab · ideation phase
It does the job of SmartGoal (GoalCam shot stats), the HeadCount heading pod, and the SinBin board and QuarterBoard from OffsideFlag, with one hub, one access point, one match clock and one app. Separately they cost $4,366 + $150/month; GoalSide is $3,790 + $150/month (target).
No. It is a timing and records aid. The referee keeps the official time, decides when a sin-binned player may return and enforces substitutions.
No. It counts headers against the FA training guidance for each age and shows how many are left. It makes no medical or safety claim.
They stay in OffsideFlag. They belong to the referee, not the club, so they were left out of GoalSide.
Coaches on the pitch. Parents only after the club approves. Players are named by first name or shirt number.
No. It is a concept in design. The CAD and fit checks are done, but it has not been built or tested. We are not taking orders, reservations or deposits.
