Flexible PCB Design

Tan is an exceptional freelancer with the eye for great PCB designs. There was a little communication issue in terms of english language with him but if you can make that 2% adjustment then it's worth it. He is better than most of the US and Indian guys I regularly hire and I plan to hire him again very soon

Portable speaker

VINC

Developing 200W, 300W, 500W, 600W, 1000W high power wireless speakers with Karaoke included. Using AC 220V/110V, 12V lythyum battery power. Material of the crate is industrial plywood, good wood. Connect to computer/phone/DVD via Bluetooth, 3.5mm Jack.

Monitor and monitor the lighting system

VINC-NAMVIET

Lighting: LED lights can be changed through 0-10V or DALI communication. Introduction: Lighting system for street lights, neighborhoods, residential areas, industrial parks, resorts... - In each place there is a central cabinet to turn on/off/down the light output automatically or manually via LTE. - Each cabinet controls from 40 to 100 LED posts via LORA communication. - At each lamp post, there is positioning via GPS/GLONASS. Uses: -- Know where the problem is to fix .... Not enough to write!
