3D Printed Lever for AirPax Circuit Breakers
This is a very specific project, but I’m writing about it anyway in case someone has the same problem. I own an old boat, with an old switch panel that has old circuit breakers. Needless to say these particular breakers are … Continue reading
Cheap Temperature Gauge for a Boat Engine
Here is a good idea I saw for cheaply monitoring engine temperatures. If your boat engine has ever overheated (like mine has) you will be a little paranoid about watching the temperature. I found some cheap digital thermostats on eBay and … Continue reading
Building a NMEA 0183 Wind Instrument
UPDATED 09/08/2016. Following on from the last project, where I broadcast NMEA GPS data to iSailor, I wanted to send wind measurements as well. The mast in my Westsail 32 was out, and it was a perfect time to put a … Continue reading

Getting NMEA GPS data in iSailor
If you have been using the iPad app ‘iSailor‘ for navigation (as I have), you may have seen the option to unlock NMEA positioning support. NMEA-0183 is a standard protocol used to communication marine information such as depth, speed, position etc. Most … Continue reading
Building a JGRO CNC Router
To enable further projects, I decided a while ago that building a CNC router would be a great idea. This would allow me to cut wooden bits for projects and engrave circuit boards. I decided on the tried and tested … Continue reading
GPS Sailing Data
Having recently purchased a Hobie 14-ft catamaran, I have been having fun out on the water, but also wondering how fast I’ve been going. To give myself some idea, I decided to make my own instruments using an Arduino, LCD … Continue reading
Robot Prototyping 101
Over the past few years, the back of my mind has been thinking about a small, quick, camera robot I could drive around. Recently, with the help of a 3D printer I was finally able to print a chassis and … Continue reading
3D Printed Phone Holder
I decided to try my hand at designing and 3D printing a phone holder using Solidworks. Two prongs on the back allow me to attach it to a car’s AC vent, and the thread on one side allows it to … Continue reading

MIDI Keyboard Visualiser
A while back I bought some cheap, multi-colour LED modules on ebay. I’m not sure what they were designed to be used for, as each time power was applied they cycled through different colour combinations. The modules had an AT89C2051 microcontroller on … Continue reading

Let’s Go Sailing Automaton
Being inspired by these AMAZING DESIGNS by Wanda Sowry, I decided to design my own automaton with a sailing theme. My first version was a failure. It was overly complicated and had too many gears. So I wrote it off as … Continue reading
