SOME PROJECTS DONE
[1] Built CNC machines (built whole machines, ... 3 Axis CNC Mill, CNC Plasma with THC, CNC Laser use CO2 and Laser Diode, 3D printer, DTG Printer use MACH3 and GLBR, Marlin)
[2] Built Robot Arm SCARA and 6DOF robot arm
[3][1] Built E-cars (Build whole a car, from chassis, exterior by fiberglass, paint whole a car, interior, design and build damping system for differential system, control all electrical devices (light, horn,...) by micro-controller, send data to LCD by Uart, have speed by hall sensors (pulse), 400 ampere metter for two motor (denoise PWM and read by shunt resistor))
[3][2] Built a instrusment LCD for E-Car (LCD Led-segment 1/4 duty, 1.3 bias -built PCB, write firmware and second version use HMI-USART LCD, write software)
[4] Built some manual machine (Auto Hack Saw, Auto Band Saw, Contact Welding, Hydraulic Lifting system, Furnace Induction)
[5] Built ATM Coin Machine (Build whole a machine for US (7 types of coin), auto detect fake coins, auto sorting coins, have RFID, QR code scanner, have hologram for advertisement application, use LCD 10.1 inch capacitive touch, API with server, build android app)
[6] Built Smart Cup Cleanner (Use UV ray, Negative ion generator, compressed air)
[7] Built Metal detector for conveyor (use principle inductance)
