KACHANG·SIA

OUR SERVICES

We build smart light and automation projects for people who don't code.

Here's the honest pitch: you have an idea — event lights, a sign, a sensor, something that should just work. We design it, write the code, test it, and send you a box with everything inside: the board, the modules, the wiring, the power supply and a guide that assumes you've never done this before. You open the box, follow five connections, and it works.

HOW IT WORKS
01
TELL US THE IDEA

A message on Telegram or email — a photo or even one sentence is enough to start.

02
WE DESIGN & CODE

We work out the wiring and write the firmware. Everything is tested before it leaves us.

03
YOU GET THE FULL PACK

One box: board, modules, wires, connectors, power supply, guide. Nothing else to buy.

04
PLUG IT IN

Follow the diagram — for starter packs it's five connections, no soldering. Then it runs.

05
WE STAY AROUND

Something unclear at 11pm? Message us. A real person who built your project answers.

THE FULL PACK — WHAT'S IN THE BOX

One box, everything inside. The biggest frustration with DIY kits is the fine print — "you'll also need a power supply, some wire, a programmer…". We don't do that. The box is complete, and we tell you so upfront.

WHAT WE BUILD
💡
LIGHT SHOWS

Music-reactive LED strips, patterns and scenes, controlled from a phone or a DMX console. Weddings, parties, shopfronts.

🏠
HOME AUTOMATION

Lights, fans and switches on a schedule or a sensor. No cloud account — it runs on your own WiFi.

🌡️
SENSOR PROJECTS

Temperature, motion or distance sensing with alerts to your phone. Fridges, counters, doorways.

📱
PHONE & WEB CONTROL

Control your build from a simple browser page — your own mini dashboard, nothing to install.

🔌
REPAIRS & FIXES

An existing build misbehaving? We find the fault, fix the wiring or firmware, and send corrected parts.

🚀
CUSTOM BUILDS

If none of the above fits, tell us anyway. If it can run on an ESP8266, we can almost certainly build it.

Most of our projects start the same way: someone with an event, a shopfront or an idea — and no interest in learning to code. They tell us what they want, we build it and pack it, and they set it up in an afternoon. That's the whole business, and we're good at it.

COMMON QUESTIONS
Do I need to know coding?
No — that's the point of the service. We do the coding; you follow a five-connection diagram.
Will I need to buy extra parts?
No. The pack includes everything: board, modules, wires, power and guide. If your project genuinely needs something bigger, we quote it before we start — never after.
What if something doesn't work?
Message us. A builder replies, usually within hours, and if a part is faulty we replace it. Setup help is always free — we don't charge for fixing our own work.
How do I start a custom build?
Message us on Telegram or email cs@kachangsia.com with your idea. You get a plan and a price, with zero obligation.
