Naughty FRDM-KL25Z Likes Being Touched

More fun getting to know the FRDM-KL25Z Cortex-M0+ development board. This time I wanted to learn about interfacing an HD44780 compatible text LCD. At first, I wasted a day trying to use one of mbed's popular TextLCD libraries. Whatever I tried, it wouldn't work. Eventually I thought I might have broken the LCD in antiquity. …

Odroid C1+ PSU Boards

    I have assembled the first seven of ten DC-DC boards for a work project using as many Odroid C1+ SBCs. As you might know the Odroid C1+ demands a 5VDC power supply, and whilst this is true, my project also requires 12VDC and to be driven by a single laptop style PSU. As …

“Murphy’s Law” Strikes Again

What happens when one buys themselves a new toy, or in this case two new toys? Something else happens to put a spoiler on things. That's good ol' Murphy for you...the git!
