A wristband that calls and texts your family in under 10 seconds the moment a grandparent falls — even with no Wi‑Fi.
Tap each one to see the thinking — so you get the “why,” not just the “what.”
Judges trust what they can see working. So we build the one part that makes people go “wow,” and the rest goes on your poster as the future plan.
The band's SIM is a 2G chip — it can call and text, but can't run WhatsApp (that needs internet). So the alert is a call + text. Bonus: it works even with no Wi‑Fi!
The big live dashboard needs a second computer and Wi‑Fi — more things to go wrong in front of judges. We use the small screen on the hub instead.
One band instead of six = one‑sixth the soldering and one‑sixth the bugs. Get it perfect once, and making more later is the easy part.
Three quick questions. Get them right to earn your Brain Badge.
Tap a part's name to see what it does. Tick it when it arrives.
Awesome ideas — save them for your poster as “where Pehredaar goes next.” Don't build them now.
Stuck, or want to ask for something? Type it — it goes straight to Papa, and he replies right here. 💙
