Case Study – Custom electronics Development

  • Service Category: Custom Electronics Development
  • Customer: Mr Barry from Australia
Customer wanted a device which could help in switching an oven ON/OFF using a timer which can be set via buttons or knob. Customer asked us to initially develop the firmware for the device. We then collaborated with the Client through a prototyping phasewith development of board design and component selection. After a successful tuning andtesting phase with the prototype, we rationalized the final design to a 2-board solution with surface mount components.

  1. Circuit Development of the device
  2. Firmware Development for the controller
  3. Prototype design
  4. PCB Designing of the final developed circuit
  Technical Aspects:
  • Controller Architecture: AVR
  • EMI/EMC compatible PCB designs
  • AC device triggering with Relay
  • Low current consumption
  • THD & SMD Components
  • Operated Voltage: 5V
  • Followed design standards
  Development Process which was followed:  
  1. The client shared his requirements via email and our engineers discussed every detail of the client’s needs and made a requirements document.
  2. Once everything was finalized and budget was approved,TechShlokstarted building the device with basic modules.
  3. After the development was done, we sent a working video to the client, to which he suggested some minor changes.
  4. After the modifications,an updated video was sent for final confirmation.
  5. The client was technical and built a bread-board test circuit to test everything at his end.
  6. TechShloksupported with configuration advice and other technical aspects while the client was trying everything at his end.
  7. Once everything lookedfine,the client provided board dimensions to fit the intended casing, and asked us to make a 3-board PCB design based on these using Through-Hole components. You can find one of the dimension images below.
  8. In collaboration with the Client we finalized the required components required for the PCB designallowing for the correct component footprints.
  9. After TechShlokdesigned thePCB, it was sent for fabrication by the client. On receipt the client installed the components and after everything was tested, it was working as per the requirements.
  10. The client decided that this was a great prototype, and that improvements could be made for the next phase by reducing the design from 3boards to 2, this new design would require a move to many Surface Mount components in the new design.
  11. TechShlok worked with the client in re-developing the solution, identifying revised component requirements and new PCB designs
  12. The final design was successfully delivered, and the client has now built several units that are operating as per the initial design brief.
    The client sent us this feedback:   “It has been a real pleasure working with you and your team in developing these timers, what started off as a simple design concept, ended up being a very professional and attractive solution. You guys were always happy to go that extra mile in getting things working, so a big thank you to all.”
