I'd be interested in this solution as well!

Sorry Uli, Im not planning on starting up any production. But, I can see if I can upload the STL file so you can print it yourself (or get some to print it for you), here on myhanse. Else, just send me your email and Ill send it your way for free. Just make sure that you print it in ABS plastic (as the original).

The buttons I bought on eBay. Here they are:

 

 

I ended up paying £21 for the lot including connectors. I kept the stop button. Else, I just printed the symbols on normal paper and glued a cut-out acrylic (£2) to put in front. I did test it to see if it was waterproof and it held just fine.

The easiest is just to buy a B20 panel from Yanmar, but it cost between £850-£1000!!

Im playing a bit around on a version 2. Which will have a glass cockpit replacing the old odometer using a 5" LCD screen (Im one of the unlucky that have a faulthy enginehour meter). But lets see...

Hi
Thanks for offering the file to get it printed by myself.
Anyway I have the same problems with the engine hour meter.
I also planned to exchange it including some gadgets for the anchor winch. Playing around with a cam to control the chain as it sometimes stuck when getting the anchor up, due to the small chain storage and the location of the winch.
How did you plan to get the hours counting? Ignition on or from the alternator? How will you drive the 5" display, micro controlled or Rasp ?
I would be interested in sharing experience.

Best regards
Uli

Im using Arduino as a controller. Ive made an assembly with a LCD shield. Its a very cheap and fairly easy solution. The timer is a bit tricky as, measuring from power on is easy but power off means there is no time to write it to the eprom. The counter in the old VDO measured from power on and a capacitor held the power long enough to write the hours to the eprom when switched off (the reason for not just overwrite the data on the eprom every minute would be the limited number of rewrite a eprom have).

To avoid including a capacitor, I programmed it such that the counter starts when power is on and the oil and alternator indicator is on (this is always the case when just before starting the motor). And switching the counter off when the state comes back i.e. that the stop button have been pushed. That give me time to write the new data to the eprom on the Arduino, before switching off the power.

I have the same issue with the chain as well. Let me know if you come up with a solution.

Actually, one of the reason for including the 5 glass cockpit (beside looking cool) was that it could include other features. E.g. I was thinking of installing a rev counter to measure the meter of anchor chain put out and displaying it on the display. Loads of other stuff could be included as well. But, big but, all this takes time, sigh.

And sorry for this becoming more of an engineering than sailing thread Confused
