the DR100W conCEPT Project

Welcome to the DR100W conCEPT Project – an electronics project for audio lovers

Watch the video introduction :

the dr100w concept project introduction in my hometown Baguio City, the Philippines

The project is dedicated for :

  • class D power amplifier, hybrid analog + digital tonal processing : EQ + tone control
  • Audio Hardware Starter (AHS) for beginners
  • MCU Programming Starters (MPS)
  • hardware design,  software design to drive the hardware
  • audio theories and practice in real life application
  • modular board integration
  • hardware and software qualification /  verification and optimization
  • design limitation and acceptance
  • a total courseware and shareware <limited to design information & software, as the hardware is not free>
  • a platform to demonstrate the use of Automatic Test Equipment (ATE) in conjunction with the DATE
  •   (DR100W Automatic Test Equipment)  and  AATED  (Arduino Automatic Test Equipment for the DR100W)

Who will use this project?

  • it is designed to my fellow audio hobbyist (limited in the Philippines, for foreign friends, let me know your interest), to learn audio circuit hybrid analog & digital, modular board integration, driven by a micro controller with powerful Human Machine Interface (HMI) with personal design of MMI (Man Machine Interface), demonstration of the process of design idea to finish project, team work, Testing, Reliability and Quality.
  • it is designed for audio lovers who want to discover hybrid analog + digital audio hardware processing .
  • it is design for MCU Programming STARTERs with the legendary and most popular MCU in the world – Intel 8051.
  • for audio tube lovers that want to explore the world of class-D amplifiers
  • for those who feel bored in their current hobby.

The Team

The Project was successfully delivered by the dr100wteam :

  • F. Dandy – Project Manager (OFW)
  • Noli Rafallo -Software  (Embedded Programmer)
  • Romel Emperado – MCU (student at that time)
  • Bryan Randol – Hardware (OFW)
  • Ariel Arello – Test / Quality  (OFW)
  • Anna Chen – Procurement (e-commerce)
