The Neon Clock – Part 2

Today, my PCBs arrived, wahoo! Therefore I’ve been able to have a quick go at making my neon clock. I tested it in parts to make sure each section worked before putting it completely together. Unfortunately, my high voltage PNP transistors haven’t arrived yet so I’m currently testing it with TO92 transistors in their place. Testing […]

The Neon Clock

Building a clock really is about as textbook as it gets when it comes to electronics projects – especially on the internet. I however have never build a clock (not intentionally anyway… I wouldn’t count the measily effort of my smartwatch!) so I’ve decided to have a go at one. Instead of doing one of […]

STM32F4 SPI VGA Controller

Well it seems all of my projects recently have been based around my LCD monitor! I think its just because its fun to actually be able to see the outcome of your work as opposed to just seeing a statement change in debug or an LED flash. This isn’t actually an original idea of mine, I […]

STM32F0 RTC using HSE/32 as the timing source

This is only a short post really. With my watch, I’d been trying for AGES to try and get the RTC working with the external crystal. It might seem simple to some but it was certainly not simple to me and ST don’t give an example, unlike most things; in their standard peripheral downloadable pack. I […]

STM32F0 Tutorial 3 – Timers Pt1

On any microcontroller, timers are arguably one of the most useful peripherals, probably along with GPIO. What is a microcontroller without the ability to measure time reasonably accurately?! Timers on the STM32 series of chips are quite complex and will be spread across multiple tutorials, each hopefully demonstrating one useful section of timers. The tutorial […]
