I planned a long, productive day, but it appeared a very short, However some things was done. Interior Cabin sole Cabin sole floor demolishing started. leftovers of water damaged plywood removed from the front cabin. My younger son helped a lot. Main cabin and galley left to do. We found the original Teak&holy floor was just decorative, it was 1/4" thick or even thinner. <<picture will update later>> I am looking for options to make PVC flooring, likely I will do it with rigid locking planks, like laminate floor, but PVC Cabin table  Checked how it fits the slipping place  to be set as sleeping platform.   It is nice, is not? However when I made it I  did "little improvement", I mare corners radius the same and make exact 90 degrees corner. Now I know  I had to make it EXACT as original one. I appeared it does not fit to place as it should to be a part of sleeping platform. It has a 1/2" gap and holding ribs are about 3/4, so, it will not sit tig...

Engine instruments I have designed Engine monitoring module. It is based on Opensource SensESP project . More details  about open source project here: https://signalk.org/SensESP/pages/getting_started/ https://github.com/SignalK/SensESP   I have bought relatively cheap 4000 RPM tachometer with M16 sensor on AliExpress, for  my 2MQ20 engine, however it appeared, that sensor signal is not strong enough enough to get it work stably on RPM >1200.  https://www.aliexpress.us/item/3256807066465803.html At any case I planned to make engine monitor module and connect sensor to it, and then to tachometer. What I had to do - add signal amplifier/filter circuit to monitor module to feed physical instrument with strong enough signal. My engine monitor board design:    What features implemented on the board? Sensor - Starter battery Voltage Sensor - Alternator output Voltage  Sensor - Throttle position (potentiometer input) Sensor - Fuel Tank "1" level (ADC input...
