Optimize the Energy Consumption of your Electronic Device

Energy consumption is an important parameter that not only concerns sustainability. It is true that by optimizing the use of energy on the device, less energy will be required to perform its function, therefore more efficient, but also by performing this optimization you will have an overall better product.  Continue Reading “Optimize the Energy Consumption of your Electronic Device”

WindAid is also Electronics

This post was originally published on the WindAid blog. The article can be found here

Back in the summer of 2014, I had one of the best experiences of my life (sounds cheesy and the start of a teenage girl movie doesn’t it?). I was just finishing university and graduating with an electronics engineering bachelor degree at the University of Plymouth and before getting hooked into a 9-5 job I was looking to have an experience where I could combine three different factors Continue Reading “WindAid is also Electronics”

Wind turbines with Twitter accounts

Wind Turbines with Twitter accounts? Unconventional perhaps, but it’s a zero service cost option I was able to implement that allows WindAid Institute, a Peruvian Non Governmental Organisation (NGO) to receive notifications from their wind turbine systems in rural Peru. The open source remote monitor project (or ReMona) was born out of a need to:

  • Receiving system alerts, such as battery level being critically low.
  • Wanting Live data to track system usage and turbine performance anywhere in the world.

PCB Technology 101

Most of us have come across PCB and FPCB in our day to day usage of electronic devices. However, few of us have ever taken time to think about how PCBs and PCBA are made. So we keep wondering how the PCBs that drive our appliances including computers and microwaves are actually made. In this article, we delve into what PCBs are, the materials used in making them, the cost and the process of manufacturing them. Continue Reading “PCB Technology 101”

Virtual Coffee with a Firmware Engineer

firmware

Nowadays, most electronic devices out there require some form of intelligence or decision making. Sometimes very talented electronic engineers can make this using purely analogue and digital electronics together and substantially reduce the costs of the project. However, it is more than common to find that almost all electronic products have a microcontroller inside. These little computers introduce the possibility of measuring analogue signals so they can be processed, enable communication between peripherals, and execute a code taking into account the inputs of your system, just to name a few things. Continue Reading “Virtual Coffee with a Firmware Engineer”

DIY Telematics Box

Lately, there has been a rise in dashcams sold worldwide to protect the driver’s insurance claims. Most of the time, these have been sufficient. I recently bought my first car and had to drive about an hour on the motorway to my first job. Being a new driver, I had my car fitted with a black box (telematics box) to monitor my driving. A few years later, I bought my second car, but I didn’t have a telematics box installed. Given the driving styles I have seen from various individuals on my commute to and from work, I felt a dashcam alone would not be sufficient, and I really wanted to have something that could monitor my driving in the event of some idiot thought they were on the set of the next Fast & Furious. So I made my own! Continue Reading “DIY Telematics Box”

Dissection of a Successful HW Product Crowdfunding Experience

gecho_ks

One of the main challenges that HW startups face is the issue of financing the project. Fortunately, in the last years, a range of different alternatives has risen allowing many companies to take that initial jump and pay for development and manufacturing costs. One of the most popular ways to finance a project nowadays without involving banks and investors is through crowdfunding. What the backers get in return can either be a percentage of ownership of the company or a special edition product (sometimes even both). Continue Reading “Dissection of a Successful HW Product Crowdfunding Experience”

The Powertree: Calculating Power Consumption

powertree2

A tree can be long, tall with vibrant green leaves and mandarins because it has strong roots and a system that can deliver its nutrients effectively without overloading or bottlenecks.

The simple structure is that a stronger entity supports a smaller one and then repeats itself. The energy to make a leaf grow will be less than the one used for growing a branch (or so I think so as I am not a biologist). And as we can assume, a branch is capable of supporting a certain amount of leaves and fruits and of delivering the nutrients and water from the roots. I think I have never seen a healthy tree with a branch with too many leaves and fruits to the point of damaging the rest of the tree because of overweight or the energy demand of the leaves and fruits is too much.
