01 — The Problem

Every house with kids and screens runs the same losing fight.

Software lockdowns don't fix it. The iPad just goes dark, the meltdown starts, and the timer that decided it all is hidden on a parent's phone.

Kids can't see time, so they can't trust it — an abstract "45:00" means nothing to a six-year-old. And every single time, a parent has to be the one who says no. The whole system makes Mom and Dad the bad cop. We're done playing that role.

02 — The Insight

Stop fighting the device. Change the psychology.

Totem removes the screen-time limits from the iPad entirely and puts an objective, physical referee on the counter. The control app lives only on a parent's phone — to add time, never to lock.

Baseline + Bonus

Kids start each day with a guaranteed floor of time — no anxiety, no working just to reach normal. Everything above that is a bonus they earn. Chores stop being a tax and become an opportunity.

Tip Jar & Bounty Board

Catch them being good? Tap +5 — it lands instantly. Want structured chores? Post a bounty as a contract; they finish, you approve, the time banks.

The Pavlovian Payout

The instant time is added, the Totem throws a party: rainbow pulse, victory sound, and the light visibly filling back up. Real-world contributions, gamified.

03 — Meet the Totem

A digital hourglass you can hold.

14:32

A sleek vertical tower of 360° light that drains from top to bottom like sand in an hourglass — so even a toddler gets it.

The cube base shows exact minutes:seconds on all four faces, readable from any angle. It glows green, turns yellow under 15 minutes, then red under 5.

It lifts off a magnetic charging dock with a satisfying snap, so a kid can carry their time to the couch like a totem of what they've earned. When it hits bottom, the Totem says time's up — not you.

04 — Why I Need You

I'll build the brains. You make it real.

Honest version: I can build the software in my sleep — the React dashboard, the Cloudflare backend, the behavioral logic. That's my wheelhouse.

What I can't do alone is turn this into a kid-proof, consumer-grade appliance instead of a wire-tangled breadboard. That's the maker challenge — and between the four of you, there's more than enough engineering firepower to absolutely nail it.

LukeSoftware & Behavior
The React/Vite PWA, the Cloudflare backend, the baseline+bonus logic, and keeping every kid's state in sync. I own the whole software side.
The CrewHardware & Mechanical
Will, Brian, and James bring the mechanical-engineering muscle; Matt brings hands-on build rigor and keeps the project organized and on-track. Together you own the tower end-to-end — structure, power, dock, displays, enclosure.

The Elegant Engineering Puzzles

The Lever Problem

A tall rigid tube on a small cube is one giant lever — knock it off a coffee table and the stress lands right at the neck. Needs a central spine (aluminum or carbon rod) and an impact-resistant PETG base the boys can't snap.

The Magnetic Dock

It has to lift off and snap back like MagSafe. Spring-loaded pogo pins, magnetic alignment rings, and a LiPo/BMS charging circuit packed into a tight cube base.

The 4-Screen Hub

Four I2C displays in one small cube so time reads from every angle — without wire spaghetti. Single screen for the prototype; a custom PCB once it's proven.

The Power Budget

NeoPixels + Wi-Fi are hungry. An 18650 LiPo in the base (doubles as ballast against tipping) plus aggressive power management so it survives an hour off the dock.

05 — The Full Stack

Clean software. Tactile hardware.

My End · Software

React + Vite PWA — parent dashboard saved to the home screen; giant +5/+10/+30 buttons + Bounty Board.
Cloudflare Workers + Pages — backend API and the source of truth; broadcasts remaining time to the device.
KV Storage — per-kid state management.
Home Assistant webhook — fires the victory sound through the Echo Show, keeping the tower lean.

The Build · Hardware (BOM)

ESP32 — Wi-Fi MCU, the brain; pulls state from the network.
WS2812B NeoPixels — the 360° light tube.
4× I2C OLED displays — the cube-base timer faces.
18650 LiPo + BMS — portable power and base ballast.
Magnetic pogo pins + rings — the snap-on charging dock.
Central spine — aluminum/carbon rod for structural load.
PETG + TPU / Silk PLA — structure + diffuser tube, printed on the Centauri Carbon.
06 — The Build Plan

Weekend sprints. We don't boil the ocean.

Bench Test · Validation

ESP32 + one LED + one screen. Prove the Cloudflare handshake — state passes from app to device and back.

Full Integration

Wire the full NeoPixel strip and feedback to the MCU. The drain animation and the "fill-up" come alive.

Physics & Power

Map the LiPo/BMS and the magnetic pogo dock. Test real off-dock battery life.

Structure & Enclosure

Model and print the spine, PETG frame, and diffuser. Integrate the hardware; drop-test it.

Mobile Tower & Polish

18650, pogo rings, base screen, and the full magnetic docking station. Deploy it on the counter.

Phase 2 — The 4-Screen Flex: multiplex all four cube faces once the single-screen prototype is solid.

That's the pitch: high impact, a clean stack, genuine engineering puzzles, and something the kids will actually love. Tell me you're in and I'll have ESP32s on the bench by next weekend.

So — which puzzle do you want first: the dock, the spine, or the screens?
