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 […]
A little update Following the past months’ trend I am not posting as often as I wish I could, but the project is alive and well. One of the key functionality I want my ESP32 based project to have is sound. More specifically, I would like it to be a […]
