Covid-19: Biosensors, BioFETs and Labs-on-a-Chip

Crucial to monitoring and forecasting the spread of a virus during a pandemic is the acquisition of accurate infection data. Traditional manual laboratory techniques have proved to be inadequate during Covid-19. Can new technology help?

Catching a Bus: Prototyping a wireless robot with MikroElektronika Click Boards

The penultimate part of my series on serial communication: Catching a Bus. The subject is a practical project which uses UART, I2C and SPI serial busses to link various OTS modules together, forming the ‘brains’ of a wireless/autonomous mobile robot.

Catching a Bus: Basic Serial Communication Part 4, I2C

Most modern peripheral device chips, such as sensors and motor drivers, communicate with a controller via a serial data bus. Microcontrollers usually support one or more of four basic types: UART, SPI and I2C. How do they work and which to choose?

Covid-19: Testing, Testing

In the middle of a pandemic and no one has any idea how many people are infected and how fast it’s spread. Modern epidemic forecasting seems to be about as accurate as nineteenth century weather forecasting, but why?

On Whiskers and Dendrites

Many early electronic components had a short lifetime. The cause was identified and fixed, but then the ‘fix’ was banned for health and safety reasons. What happened to the forecast electronic apocalypse?

Build a ‘real’ Mars rover

Most ‘hobby’ mobile robots on the market are usually of the 2-, 4-, or 6-wheeled variety with no suspension or steering systems. Changes in direction are achieved by varying wheel-speeds – so-called skid or tank steering. Not this one.

How big is your Electronic Tech’s Carbon Footprint?

Everyone knows that gaseous emissions from fossil-fuel burning to bovine flatulence are the cause of global warming, right? Indeed they are, but less obvious causes of a high carbon footprint are becoming apparent. And your ‘Tech’ may be involved.

Clicker 2, FORTHdsPIC and more Bare-Metal

The porting of my FORTHdsPIC code to the fast version of the Microchip dsPIC33 digital signal controller has demonstrated – once again – that bare-metal coding is not for the easily frustrated!
