Moistly: The journey from (Arduino) idea to product

Last week, we started selling Moistly, a simple device that helps you remind to water your plants, when it senses that the soil is getting dry.

How to run an Arduino (clone) on (AA) batteries for over a year – Part 2

A short while ago, I wrote a blog post about running an Arduino on batteries. That post was well received and got many upvotes, likes, tweets and comments (Thanks everyone!). That post discussed among other things getting rid of energy suckers, low-quiescent current regulators and the use of sleep-mode. This post will discuss how to […]

How to connect an Arduino to the Internet for 10$

I quickly found out however that this wasn’t going to be easy: A battery would only last for a few days, before it would be gone. Browsing around the internet, I learned about the fantastic work of Jean Claude […]

How to build a 5$ Arduino (clone)

If you are like me and build projects with Arduino, you must have felt the frustration with ripping your project apart, because you wanted to build something else with that Arduino. I have had the same issue many times, so I decided to find a way to solve this once and for all. Hence, how […]

How to go from (Arduino) prototype to (selling) product

While reading Arduino and DIY hardware forums, I noticed that quite a few people have questions about moving from an Arduino prototype to a (selling) product. Since I have done this a few times and have learned a lot during the years, I decided to share what I think is the best (quickest, cheapest and […]
