Whitterm-220 Clever Serial Terminal

21/12/18 UPDATE: Hello to Hack a Day readers. This project was shared when I did it but re-posted recently. It is 2.5 years old and there are many things I would do differently. I am considering work on a IO board specific to the project (RS232 driver, GPIO break-out, proper RX/TX LED buffers and potentially […]

Garmin Quarter Turn iPhone Mount

I frequently find┬ámyself navigating ’round on my bike, juggling Google Maps precariously in one hand. I don’t appreciate the bulky handlebar phone mounts about so thought I’d make┬ásomething to neatly integrate with the Garmin Quarter Turn mount…

Noise Crayon – Noise Amplitude to Light Spectrum Converter

Continuing on from my Ambient Noise Level Indicator, I wanted to create an enclosure and make it stand-alone – not requiring a computer to do the processing. I ended up with a little device that converts noise amplitude to the light spectrum: Noise Crayon. The Ambient Noise Level Indicator used the MCU serial host Processing […]

Ambient Noise Level Indicator

As part of my work at MACH Acoustics – understanding how internal ambient noise levels affect different environments – I was inspired to create an indicator that shows when noise becomes higher than the base level. Some solutions already exist but they are pricey (because they used calibrated sound level meters), and not very engaging. […]

Long-Range Coastal Autonomous Underwater Vehicle (AUV)

The second semester of the third year of my Mechanical Engineering degree was a group design project. My group of six was tasked with the design of a coastal autonomous underwater vehicle (AUV). I was assigned design of the gliding sub-system (a long-range AUV it had to optimise energy use) and was also the business […]

HDD Clock

With a cupboard full of old hard drives and some spare time, I recently set about making a persistence of vision clock. Using the platter of a hard disk, a slot is cut to allow backlighting to be emit. When the disk is spinning at 5400rpm+ and backlight constant, the disk appears opaque, as the […]
