About this Gig

Hello and Welcome!

Custom toy electronics require precise signal handling, reliable motor actuation, and compact circuit integration to deliver consistent, responsive control.

I design custom toy circuit boards, joystick interfaces, servo controllers, and embedded systems for interactive toys, robotic toys, RC devices, DIY mechanisms, and electromechanical prototypes.


What I Will Provide:

  • Custom toy PCB design and schematic development
  • Joystick input circuits and analog signal processing
  • Servo motor control and PWM signal generation
  • Microcontroller integration (ESP32, STM32, Arduino)
  • DC motor, actuator, and driver circuit integration
  • Embedded C/C++ firmware development
  • PCB layout, component selection, BOM, and Gerber files


Why Choose Me?

  • Engineering focused, application specific circuit design
  • Reliable signal processing and responsive actuator control
  • Firmware and hardware integration expertise
  • Clear communication and structured technical delivery
