I made this diagram years ago and posted it on the Cruising Forum. The problem there is that it simply is too hard to find and it gets lost, so I’m posting it here instead. The goal of all my diagrams is to be a reference and this is
We have been testing different halyard setups for our roller furling jib for more than 10 years. Our preference is to use a two part halyard, i.e. a permanent part and a second part that is only used during hoisting and lowering the jib. The rendering above shows a
The past week we have been planning projects for this summer. Besides finishing the ceilings, hull lining and replacing our jib furler and forestays, we also want to make modifications to our cabin soles and our pilothouse. These modifications are difficult, requiring probably weeks of making patterns and templates for
This morning I received the JLPCB shipment from Fedex. They look fantastic, better than anything I made before and they are cheaper than anything I made before, even my DIY PCBs. Below some more pictures incl. screenshots of the production timeline and shipping progress. You can see that they did
I found good maps made by Michael Ferragamo, https://ferragamo.gumroad.com showing the actual landfall positions of all hurricanes in recorded history on. The above one is for the whole Atlantic basin, below is another one for the US East coast. From what I understand, meteorologists expect a somewhat
Above an impression of the finished PCB design for the main controller module. About half the board is taken by the ESP32 module with POE Ethernet port; the other half has two relays and an optocoupler to interface with the Remote Battery Switch, another relay to interface with the active
I finished the design for the controller board. It uses the Waveshare ESP32-S3-ETH module with the POE power over ethernet module. This module has an Ethernet port that will be available on the outside for connecting it to our network switch. The POE converts to 5V power and the module
My reason to use the ATtiny85V microcontroller is that it has a power-down sleep mode where it consumes as little as 1 µA, which equals zero for any practical purposes. The reason for consuming anything at all is that we can wake it up by changing the state of an
Last year I designed BMS v2 and built a prototype that worked great. I continued to design the circuit boards, finished that and then never actually ordered them… because I didn’t like the large size and mass of cabling. What I liked about the design is that it uses
We have now been using Wireguard VPN’s between our Spectrum Cable Internet in Florida and our KPN Internet service in the Netherlands for a couple of weeks so I think we can come to some conclusions. We use these in several ways, let’s start with the simple ones:
I previously called these gadgets a scam or at least a barely allowed trick and I did receive some feedback on that, asking if a company like Victron really is selling a scam product so let me put this into context with this post: I call these gadgets scams or
You can buy a LIM for $1000-$2000, which is a great deal for a hospital operating room but a bit stiff for a sailboat where nobody dies when AC power is disrupted. A couple remarks before diving in: the diagram above is conceptual, not an actual schematic, which requires
