All my PCBs
I’ve designed PCBs for projects like the constant current load, real-time room occupancy system, PCBs to solve my own needs like making ac-dc power supplies, microcontroller boards etc. For conducting a workshop at my college; I designed an ATmega microcontroller board.
It all started with the RoboCon PCB designing workshop in my first year of engineering. We designed a blinky board which blinked 2 LEDs in sequence. It gave me a basic idea of PCB designing and I was on my way to designing more complex PCB’s.
Using this newly learned technique I went on to design and build my own DC power supplies which I still use to this day.
Next, I designed a micro-controller board very similar to an Arduino. I did this as it was more cost effective and I’d have another board that I could use in my projects.
Next, I designed the constant current load board which would be the most challenging design to date. The PCB was too complex and impractical to build by hand so I decided it was worth to get it professionally manufactured. I designed the board in Eagle and got it manufactured from PCBway (PCB prototyping company based out of China).
Constant Current Load
Next, I designed the ATmega board for the “Introduction to Embedded Systems Design, Embedded C Programming, PCB Designing and Soldering” workshop that we conducted in college. We assembled and distributed 10 boards for the workshop.
The last board that I have designed so far is for the real-time room occupancy system. It is the smallest board I have ever designed with the most component density. I have used small SMD packages like TQFP and SOT which have a very small lead spacing are quite challenging to solder by hand.
Room Occupancy Sensor
Needless to say, I still have a lot to learn in the domain of PCB designing and I am only just getting started and the journey has been satisfying so far…..
