As of today idyl.io is officially upgraded to a brand new dedicated server. It’s a pretty beefy Xeon with 32GB of RAM and dedicated bandwidth. This is also why you might have had some issues accessing the website while I was ironing out the last problems. Setting up SSL certificates […]

A new page has been created in the lessons section, talking in depth about the ubiquitous linear regulator. If you wish to jump right in, the page can be reached at https://idyl.io/electronics/power/linear-regulator/ You will learn: How linear regulators are built How to take in consideration the “drop out” value of […]

This post is now outdated: the Power Supply project is now complete and available for sale on Tindie. Link to the Tindie Page Link to the complete write up of the project ORIGINAL POST BELOW: My nixie clock power supply died. It was one of these cheaply built Chinese modules […]

The rotary encoder is a great user input device with a satisfying tactile feedback. A lot of user interfaces are slowly transitioning towards button-less devices, but when in need of a physical system, I always love to use encoders. However if you have ever worked with one, you know they […]

A few weeks back I posted about the TAS5733L; a promising all-in-one I2S codec coupled with a DSP and a class D amplifier. Unfortunately; I could never make it work. Luckily this is not really a problem anymore since Texas Instruments recently released a younger, more powerful brother called the […]

Today we are reviewing the PCBs made by PCBWay. PCBWay is part of the big PCB manufacturers in Shenzhen; and is lately aggressively targeting the maker and hobbyist market. The market might be pretty small, but it is driven by a very vocal community and it looks like PCBWay doesn’t […]

After publishing a review of the STM32 “Blue Pill”; there was only one thing left to do: how to program it with Arduino of course! You will find the complete tutorial by accessing the menu, under Arduino; or simply by clicking on the link below. Enjoy! Access the tutorial  

Arduino has been traditionally dominated by Microchip-Atmel chips. The Uno uses a 8 bit AVR, and the newer boards have a 32 bit SAMD21 ARM core. Enters a new alternative, code name “blue pill”; and it’s fantastic! What is the STM32 Blue Pill? The STM32 “Blue Pill” is a development […]

A new “Electronics” section is now available from the menu! Electronics are everywhere. Now, they’re even in your fridge and having your toaster connected to the internet through a small chip is only a matter of time, if not done already. What’s more: electronics of today are different than what […]
