Re: Looking for small, affordable printer for on the boat

For $40, likely not...they probably dont have sunlight readible screens either.

But I just ordered an HP Omni 10.8" Windows 8.1 tablet with Office for $245 on Amazon. It will run OpenCPN and...

Re: Arduino / Raspberry Pi based instrumentation?

Pi is ARM chipset. I believe it *CAN* run OpenCPN, but you're going to have to modify it and recompile it. Even if it does run it, it'll be poor performance since the Pi is only a 700mhz chip (not...

Re: Arduino / Raspberry Pi based instrumentation?

You're right about more work than planned.

Your idea is intriguing. I'm concerned about "inferring" resistance levels though. I mean, where do I correlate the values to to determine true...

Re: Arduino / Raspberry Pi based instrumentation?

You know you're right. But I dont have the pi hardwired. It goes through a 12v -5v brick...or through a usb hub which takes in 12v. Just wanted the 12v to be steady.

Re: Arduino / Raspberry Pi based instrumentation?

Well - I think I figured out why the data isn't flowing for NMEA. Tore the whole aft cabin apart to get to the Raymarine NMEA interface box. After plugging the pi directly into the box (you should...

2 - sensor should send the data not to the helm, but utilizing arduino to the raspberry pi

Re: Arduino / Raspberry Pi based instrumentation?

The Maretron units are pure N2k. Just saying that if Maretron is able to take analog senders from Yanmar and convert to a digital signal....we should be able to do the same.

Re: Arduino / Raspberry Pi based instrumentation?

Is there any impact to having the oil pressure be "teed" or on a hose further away from the engine block itself? Or does it even out across the entirety of the measurement surface?

Re: Arduino / Raspberry Pi based instrumentation?

Whoops! Looks like you're right about the senders being limit. Here is an example of what someone did to "tee" in a coolant temp gauge.

Re: Miami to Bimini

Re: 1981 - Catalina 30' or Sabre 30'?

Sabre is definitely still in business...they just make powerboats and no more sailboats. The Catalina 30 is out of production too...and has been for over a decade now.
