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 […]
It’s been a month since the last update. Check out the previous post for the complete history of this project! Being a hobbyist sometimes mean you don’t have as much time to sink in your projects as you would like to, but you have to live with it. Nonetheless, there […]
I have been talking about VFDs for a long time now, mainly how to power them. I now have my PCBs for 12 IV-25 tubes ready and soldered! The big display You have to imagine this panel upright, 6 of them side by side. That will give a total area […]
Today we are reviewing the PCBs made by JLCPCB. JLCPCB is one of the bigger Shenzhen based PCB manufacturers out there. Although questionable, they claim to get over 8000 orders per day. More recently they got a lot of community support by partnering up with EasyEDA; but they also made […]
