- 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.
- Circuit Development of the device
- Firmware Development for the controller
- Prototype design
- PCB Designing of the final developed circuit
- 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
- The client shared his requirements via email and our engineers discussed every detail of the client’s needs and made a requirements document.
- Once everything was finalized and budget was approved,TechShlokstarted building the device with basic modules.
- After the development was done, we sent a working video to the client, to which he suggested some minor changes.
- After the modifications,an updated video was sent for final confirmation.
- The client was technical and built a bread-board test circuit to test everything at his end.
- TechShloksupported with configuration advice and other technical aspects while the client was trying everything at his end.
- 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.
- In collaboration with the Client we finalized the required components required for the PCB designallowing for the correct component footprints.
- 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.
- 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.
- TechShlok worked with the client in re-developing the solution, identifying revised component requirements and new PCB designs
- 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.”
