Dynamic LED Smart Jersey PROTOTYPE

What You Actually Need (No Extras, No BS)
You need one working jersey prototype that proves the concept.
That’s it.
The prototype must:
Physically feel like a normal jersey
Comfortable
Flexible
Washable (or at least water-resistant with removable electronics)
No bulky or intrusive hardware
Light up with programmable light patterns
LED array (numbers, logo, panels, or pixel zones)
Multiple patterns (static, pulse, wave, chase, etc.)
Bright enough for stadium visibility, but not rigid or hot
Connect to a phone
Bluetooth (BLE is fine)
Phone can:
Turn jersey on/off
Select light patterns
Adjust brightness / color
Your internal team handles the app — freelancer only needs:
Firmware
Bluetooth protocol / commands
Documentation for your app team
What You Do NOT Need From the Freelancer
This is critical to state explicitly.
❌ No app UI
❌ No backend
❌ No AI
❌ No cloud
❌ No stadium mesh
❌ No mass-production tooling
❌ No marketing fluff
Just:
Hardware + firmware + physical jersey integration
Freelancer Scope (This Is the Job)
1. Hardware Design
They must design:
Small rigid PCB (not flexible)
LED driver + microcontroller
BLE module
Battery management
Magnetic charging contacts (sealed)
On-board power button (or magnetic reed switch)
Key constraints
Fully sealed electronics (silicone or TPU encapsulation)
Sweat + wash resistant
Low profile, lightweight
Battery sized for 2–4 hours active runtime
2. LED System
LED type: addressable RGB (WS2812 / SK6812 or equivalent)
LED layout:
Numbers
Logo
Or pixel zones sewn/laminated into jersey
Wiring routed safely and flex-relieved
Replaceable or serviceable if possible
3. Jersey + Textile Integration
They must:
Select appropriate jersey fabric
Integrate LEDs without stiffness
Hide wiring
Design mounting location for electronics module
Ensure comfort + breathability
This can be:
Sewn channels
Laminated layers
Removable electronics pouch
4. Firmware (Critical)
They must deliver:
Stable BLE firmware
Command set like:
SET_PATTERN
SET_COLOR
SET_BRIGHTNESS
POWER_ON / OFF
Documentation so your team plugs it into your app
No fancy UI — just rock-solid firmware
5. Deliverables (Non-Negotiable)
You want these in writing:
Physical
1 fully working jersey prototype
1 spare electronics module (if possible)
Engineering
PCB design files
BOM
Firmware source code
BLE protocol documentation
Assembly instructions
Testing
Battery runtime estimate
Heat output
Wash / water resistance notes
What Kind of Freelancer You’re Actually Looking For
Not “maker-space hobbyist.”
You want:
Wearable electronics engineer
Experience with:
LED wearables
BLE devices
Textile integration
Consumer electronics prototyping
Good keywords:
“Wearable electronics”
“BLE firmware”
“LED textiles”
“Smart clothing prototype”
Timeline Reality (Reasonable)
Design: 2–3 weeks
Hardware build: 2–3 weeks
Integration + testing: 2 weeks
Total: ~6–8 weeks for a legit prototype
Budget Reality (So You Don’t Get Garbage)
$5-$10k is the real range for someone competent
Under that → expect fragile, flaky, or half-working
Over that → they’re trying to build a product, not a prototype
