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).

Are your tree roots well designed?

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.

Crystal oscillator for your digital ICs

Just as a stable voltage source is necessary for any analogue circuit to work properly, a clock is required for any digital circuit to appropriate shift from one state to the next. In this short article, we will look into the design of an oscillator circuit to give your circuit’s MCU or any other digital IC the necessary clock to perform its functions.

Battery types and voltage regulators comparison

Battery and TO220

A device’s power source and power management areĀ one of the most important parts of any electronic product. After all, without a stable voltage source that can supply enough current for the circuit to work properly, there is no life. In the last decade, there has been an exponential increase of electronic products that have a battery embedded into them. So the need of knowing the different battery types so you can select the correct one for your application is required more than ever.

Why you really need a Worst Case Analysis

WCA vector

What is the worst it can happen? It’s a good question to ask when you are taking a decision. So you imagine yourself going through the worst situation caused by the worst decision you can make and decide if you can go through it or not. Or maybe you need more factual data than just a thought experiment, so you go, do it and find out that everything is fine and you were over exaggerating the consequences. But were you?

When you start a new journey, don’t forget your map!

Tube map electronics

No, I am not talking about jumping into the wilderness, visiting an old European city or using Google Maps to get to your destination. Actually, the correct analogy would be more like going to a giant mall and having a map showing where the different shops, staircases and lifts interconnect the different floors. What I am referring to is a very powerful and simple tool which is normally overlooked by more analytical and less visual people, I am talking about our device map or more commonly known as a circuit block diagram.
