Hardware Development
I m a subscriber to ST s regular email newsletter and though most of it isn t interesting to me I did notice that in one of the recent editions they were promoting their wireless range of STM32-based MCUs. As a big fan of the STM32 this caught my eye and co-incided with some ideas that were spinning [ ]
In my previous article I documented the design and build process of my USB microphone based around an STM32F446 MCU. If you haven t already read it then it s probably worth catching up now before reading the rest of this article so that you have the necessary context. The problem I ve been using the microphone for [ ]
Here in the UK the new reality of working in the IT business over the past year has been that we re all at home working remotely over virtual desktop connections and for someone engaged in software development this is a setup that works well. Having to commute 90 minutes each way into London every day [ ]
I ve been an avid user of ST s F0 series ever since it was launched. The 48MHz Cortex M0 is almost always the perfect MCU for every project that I tend to build and it s so easy to program and debug that, for me, it s the default answer to which MCU should I use for this [ ]
I like big, high resolution monitors. The bigger the better. I can t understand how so many young developers and engineers seem to be content to peer into the tiny screens on their Macbooks that offer only a few visible lines of code in perhaps two simultaneous columns, with any web-based reference material in a window [ ]
Seven segment LEDs are an extremely cost effective way to add a large, bright and very readable numeric display to your project. Displays similar to the one pictured above can be had for as little as 50 cents each on ebay in the common heights of 0.56 , 0.36 and 0.28 . You can choose anywhere between [ ]
In a previous article I described the design and build of a temperature sensor board based around a high precision LTC2986 part from Linear Technology. The project was successful so you may be wondering why I m bothering to design another board when the LTC2986 probably cannot be bettered by any other fully integrated part on [ ]
My previous article documented how I designed and built a PCB that hosted three relays and a triac that could be mounted inside a PC case and connected up via the USB bus for host control using simple commands. The relays and triacs board That board is of course the output part of the system, [ ]
In my previous article I discussed how I intended to convert an old PC into a controller that I could use to automate the temperature control required to ferment and conditional beer. If you haven t already read that introduction then I d encourage you to do that so you know what it is that I m trying [ ]
Not a lot of people know this, but I brew my own beer as a hobby; and I m not talking about the murky coloured astringent tasting dodgy brews of yesteryear. The beer I brew is probably best described as craft ale. I do the whole process, much like a brewery would. I design recipes, crush [ ]
