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 […]

STM32F0 – Software capacitive touch

Capacitive touch is “rad”. By utilizing one of the simplest physical characteristics of an object – charge storage, one is able to measure the presence of a grounded object including touch and pressure. There are a couple of capacitive touch libraries that I’ve seen around but many require dedicated hardware, for example the TSC peripheral […]

SDRAM + VGA + FPGA = SPI Addressable graphics card!

Having already written an SDRAM based VGA controller, I’ve finally got round to writing a simple SPI module that allows my STM32F0 discovery board to write to the SDRAM during blanking. In the video above, I hadn’t implemented a “busy” pin so my STM32F0 was spamming pixels regardless of whether there was blanking or not. […]

Swarmbots Update 1

So unfortunately, I’m still waiting on my batteries to arrive meaning I have to make do with some extra Li-Pos I happen to have lying around (…as you do). I gave a demonstration to one of my lecturers – soon to be my project supervisor over the summer, and he showed an interest in a minimal […]

Swarmbots – Initial build and testing

Today, my Swarmbot PCBs arrived! I’ve put one of the robots together to get a feel for where everything would go and what it would look like so its not too pretty but it seems to be functional and I’ve got the robot working autonomously in obstacle avoidance mode using the front IR sensor. Build […]

SwarmBots – The intro

Robots! Who doesn’t like robots… I’ve never to day done any projects in robots now while I find them cool, the reasoning for which is they’re generally pretty expensive. Therefore, I’ve decided to try and design the smallest most functional micro robot that I can. One of my main aims was to be able to […]

STM32F0 Simple Boost Converter

Having changed my degree title from Electronic engineering to Electrical and Electronic engineering, means that I have to take some power modules. While I don’t find mass power transfer particularly inspiring (HVDC links, the grid and power networks blah blah blah), I find small power conversions pretty interesting, the low power stuff that enables us […]

STM32F0 – High sample rate ADC usage

My current university project is based around non destructive evaluation using ultrasonics. I’ve been delegated the task of trying to design a suitably cheap (cheap being my speciality 😉 ) low end ultrasonic evaluating system. This involves designing the high voltage supply, the output driver, a high speed amplifier system AND the whole digital domain […]

STM32F0 Software UART

Well it certainly has been a long time since I last posted! This however is something I’ve been wanting to try and implement for a long time, I just haven’t got round to it as of yet. So what is it you ask? How about: The ability to use UART on any pin with edge […]
