Ph.D.
Sometimes students or other nice people ask about my Ph.D. thesis. Probably just being polite. Well, here it is.
I earned my Doctor of Philosophy in Aeronautics and Astronautics from Stanford University in 1999
Continue reading “Ph.D.”Dumbo the Autonomous Boat
Dumbo is an autonomous research vessel constructed by students at Cal Maritime. Dumbo carries temperature, salinity, and dissolved oxygen sensors and makes oceanographic observations in the waters off of the Cal Maritime Campus. This work has been supported by the CSU Council on Ocean Affairs, Science & Technology (COAST).
NMEA 0183 Speedometer
I had an email request to find this project from 2010… I updated the code too!
This project takes the pulse from a paddlewheel boat speed sensor and makes an NMEA output on the serial port. It should work with most through-hull speed transducers, and also with windspeed transducers too. The NMEA stream comes from the arduino serial port, so if you have a USB arduino you can hook it up to a laptop easily. If you want to hook it up to another NMEA instrument you’ll need something like a MAX232 chip to take the TTL logic from the serial port pins and convert them to RS-232 (or convert to RS-422 to meet the NMEA specification).
Hello world!
If you’re looking for my old site, sorry it got hacked and had to be put down.
You can email me (mholden at csum dot edu) if you are trying to find something specific.
