Ep. 100 - First Off-Shore Passage; Halifax to St. Johns The Digital Mermaid 2024-09-23 | I was invited to crew for an old friend from Halifax to St. John's (Conception Bay) earlier this summer. It was a much needed, extremely lovely trip, and I knew I wanted to save it for episode 100. This is my personal favourite video so far.

It's been a slog, but holy moly have I ever learned a lot. ^_^We use MCP4725 12-bit DACs to send voltages to the controller, and a TI ULN2003a Darlington transistor array to flip the switches going to the controller.

Ep. 83 - A Hard Day, With Good People The Digital Mermaid 2023-11-17 | This was the hardest day on the trip home... I lost cooling, the engine overheated, and I crashed into rocks trying to turn to the tow path. I worried about blocking the canal, so I called a "securite", and the USCG called out police and fire. In the end, it all worked out, but it was the lowest point I've hit since I started this project.In the end, though, I am grateful this all happened. It was a test of my commitment, sure, but far more, it underlined and highlighted how many wonderful and good people there are out there.

Ep. 79 - Mast Down, Breakdown! The Digital Mermaid 2023-10-16 | This is a long one, folks! This is the second (of four!) breakdowns on the trip home. This one was really tricky to sort out, and we covered pretty much the _entire_ fuel system on the boat. I wanted to share the whole process in the off chance it might help someone else down the road.In the end, it appears that some gunk clogged the pickup tube, some of it got through the filter and into the Yanmar's fuel pump, blocked it. This built up pressure, and the primer bulb popped. Got my first (and hopefully last, for a loooong time!) tow to a marina.

Can I Charge LFP Off An Alternator, Cheaply? - Renogy DC-DC 40A Charger (Ep. 62) The Digital Mermaid 2023-05-03 | I need to charge my LFP house bank from my alternator for the trip home, but I don't want to spend a small fortune on a Wakespeed WS500. Can I use the Renogy DCC1212-40 DC-to-DC Battery Charger? In this video, I try to figure out how to use the charger. In a future video, we'll install it on the boat and see if it works.

The Lost* Art of Cable Lacing - A Non-Expert Tutorial The Digital Mermaid 2023-04-12 | This is an attempt at a tutorial video, from someone who is NOT an expert. ^_^Years ago, I taught myself how to do cable lacing, an old technique of managing cables. I saw a NASA guide on it, and if it was good enough for NASA, well then my nerd-heart had to try! The plan is to eventually lace all the cable harnesses on the boat, so this was my excuse to shake the cobwebs off and pick the lace back up. I hope some find it interesting, and maybe even a little useful!patreon.com/TheDigitalMermaidLinks:* NASA - standards.nasa.gov/standard/nasa/nasa-std-87394* Techlace - techflex.com/lacing-tape/braided-polyester-dacron-lacing-tape* Aeroelectric - http://www.aeroelectric.com/articles/cable_lace/cable_lace.htmlChannels that have Helped Me;* @ProjectBrupeg * @BillCarlson (Project Lightening)* @OffGridGarageAustralia* @LadyKSailing * @AcornToArabella 0:00 - House-Keeping0:32 - A Request For Feedback1:38 - What is Cable Lacing?2:42 - NASA, But Different4:08 - I am NOT an Expert4:51 - Avoiding Knots, Liberating Cables6:09 - Starting Lock Stitch8:04 - The Running Stitch10:37 - Winding a Bobbin11:41 - Extending the Running Stitch12:49 - Closing Lock Stitch
285 Ah Gel to 1120 Ah LiFePO4! (Ep. 60) The Digital Mermaid 2023-04-09 | After a while working with diesel, we're back to electrics! In this video, we convert the 280Ah LFP 48v battery into 2x 560Ah 12v batteries, for a total of 1,120Ah! That should be enough to get Mermaid's Rest home with some creature comforts!patreon.com/TheDigitalMermaidLady K Sailing Discord Server:* discord.gg/MEVaWbTSKkChannels that have Helped Me;* @ProjectBrupeg * @BillCarlson (Project Lightening)* @OffGridGarageAustralia * @LadyKSailing * @AcornToArabella 0:00 - Intro and Tasks1:09 - New Plans; Trip Route2:19 - New Plans; Propulsion Batteries6:08 - New Plans; 12.8v Batteries, 2P4S9:38 - A Bus Bar Experiment!10:42 - Planning the 2P4S Battery Boxes15:46 - Amperage and Wire Gauge16:51 - 2P4S Bench Assembly20:42 - Back to Building the Boxes22:16 - Renogy 40A DC/DC Charger Plans25:50 - Fridge Failure and Possible Repair26:50 - Assembling The Batteries in the Boxes30:19 - Nuts!
