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

Ronald Sousa — Fri, 07 Oct 2016 05:39:30 +0000

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
PERT charts– Program evaluation and review technique
Gantt chart
Ronald went to Embedded Systems Conference 2009. Here’s where I first meet Jack Ganssle but I doubthe remembers Ronald
Should Manager have the same discipline as the people they are managing?
The assumption that your manager makes isn’t necessary same assumption that you are

mention that we have plans to test out machine learning. Possibly neural network

#2 – Running a contract business is hard

Ronald Sousa — Thu, 29 Sep 2016 06:43:56 +0000

In this episode Ronald talks about some of the common issues you could run into when running a contract business.

Show Notes

Keep your running cost low
Do you really need to pay for an office. I only had a small table when I first started out!.
How contract work won’t necessary give you the freedom to work on your own project
Don’t underestimate the time you spend chasing invoices, new client and general paper work
Some people automatically assume that you are well off or rich just because you have your company. Yeah right
Make sure that you really do your math/research when calculating your rates
Don’t forget to make a backup plan and be ready to excuted if things don’t work out. Can you survive without an income stream for three or four month?
be ready for when not if your client don’t pay you
Some bridges are made to burn

naming things is hard!
In this episode, Ronald @opticalworm introduces himself and what this podcast may or may not be.
He also talks about how naming things can be difficult including code variables and how your naming habits can bite you back. He ends the show by talking about the company robotics project.

Show Notes

Ronald starts by first apologising for not knowing exactly what the show is about and his random nature when explaining stuff
Also Mentions that he won’t be teaching you how to push electrons with firmware in this show
Highlights that even those he’s not cutout to be a traditional teacher his good at teaching you as an apprentice
Mention that his one of the embedded instructor at contextualelectronics.com and what he does in there
Here are some of the awesome podcasts mentioned on the show.
List the places that you might have seen Ronald
Ronald’s 3rd year university robot project testing the LED status.
talks about how naming things are especial code variables
the names code variables can in some cases give away the author. There’s no hiding from Wipe!
Points out an issue you may have with javascript when creating and naming global variables inside functions
