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 […]
My nixie clock power supply died. It was one of these cheaply built Chinese modules so it doesn’t come off too much as a surprise. Looking at how to replace it, I realize there is a dire need for a better high voltage design out there. Most the kits seem […]
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 […]
In my previous post I was talking about the TAS5733L, an audio amplifier from Texas Instruments that should be compatible with the ESP32 and its implementation of the I2S protocol. I wanted to verify that compatibility before I embed the chip in a bigger design so I built a breakout […]
