In one of my previous projects I built a masthead wind sensor using an Arduino to process the signals and output a NMEA string. Next I wanted to make an instrument on the boat to display the information. I found … Continue reading
It’s taken a while, but I finally have my JGRO CNC machine built and running. I spent a bit of time investigating a lot of ground noise on my stepper drivers. I’m using three Gecko G251 stepper drivers for the … Continue reading
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
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
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
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
