This show is for anyone who is interested to hear and possibly learn from an embedded engineer turn contractor. Theme-wise, it's Embedded electronics with a bias to robotics and humour.

**Warning, this show is essentially Ronald's logbook and just like anyone new to the world of logbooks, the ration between doodles and graph will eventually settle to a nice stable balance. Until then hang on for the ride because this might will be bumpy.

    #3 – How long will it take you to design a line following robot?

    In this episode, Ronald talks about why you should track the time you spend on a project/tasks as well as some of the ways/tools that you could use to track them. Ronald also talks about the plans for the micro robots. Ronald also briefly explains how RTOS work and give an example where you could use it.
    Show Notes

    For a contractor/freelancer, keep track of your time on a project/task is important. it could mean the deference between making or loosing money
    Over estimating the time it takes to complete a project/task could be just a bad as underestimating it
    Project tracking is a pain to do and can slow you down in some cases
    Its hard to estimate a task because of the nature of the job we do. Its not like we have an IKEA instructions for the product that we design
