==== Cooking ====

Changed to an old Optimus 155 paraffin cooker.  Spares/repair parts are here: http://fogas.se/produkter/
==== Instrumentation ====

Things I'd like to have are: 

=== A battery monitor ===

[[http://www.societyofrobots.com/member_tutorials/node/101|DW2438 based monitor]]\\

[[http://www.coolcomponents.co.uk/catalog/product_info.php?cPath=36_61&products_id=474|Hall-effect sensor chip]]

This one is a wind speed & current sensor for a wind generator, but has aspects useful for battery/power monitoring:\\  [[http://openenergymonitor.org/emon/node/135|Wind generator speed sensor]]
=== Wind & Depth Sensor ===

I bought the Garmin GMI10/GWS10/DST800 NMEA 2000 bundle.  Wind/temp/barometer/depth/water temp are done.

=== NMEA 2000 Bus ===

NMEA 2000 is based on the CAN bus spec, at 250khz transmission rate.  Sparkfun has CAN bus Arduino shields, which I've ordered and will attempt to reverse engineer the NMEA 2000 messages with.  The bus contains two wires for power, and two for serial data.  It's terminated with 120 ohm resistors, so it should look like 60 ohms to a meter.  More info:

[[http://www.can-cia.de/index.php?id=496|J1939 message format notes from the CiA]]\\

== Stealing Power from NMEA 2000 ==

I have a couple of NMEA 2000 instruments now, but my plotter is older and not NMEA 2000 capable.  That makes cabling the old stuff still a little painful- however, not if one powers known to be low-powered devices off the NMEA 2000 bus by using a field-installable male connector with only power connections wired.  I tested with my 3005c plotter, old NMEA 0183 17HVS antenna, and don't see any issue with this arrangement.  If there's an issue with the device, like there could be with a 2000 device, you can always disconnect it to isolate it from the bus.

Normal NMEA 2000 connectors: can't remember the part number

==== Bronze ====

Bronze equipment from Spartan in the U.S.  They have a bronze chain-cover, bronze bow-roller, and an awesome "mid-rail" chock that has a cleat in the center (just realized we can't do the mid-rail chock because the genoa car track is over the center of the rail): \\
