Clear Silcone

Sola Lights

Since this was my first year of boat ownership, I wanted to put lights up for the holiday season. I put them up in mid November and took them down in early January. I used three strings of lights, one at the forestay, and one on each of the backstays.

I have a full canvas cockpit cover, which meant that one of the light string connections could be out of the weather inside the cockpit, but the other connections would be outside.

I ran a single string up the forestay with the plug at the base, dropped into the anchor locker so it wasn’t sitting on the deck. I ran an extension cable from the cockpit over the deck to the anchor locker.

I joined two light strings together and used the main halyard to pull them up the backstays.

Clear RTV Silicone Sealant 66B

I had this tube of silicone sitting around so put a small bit on the flat part of each outside plug before connecting them. It seems to have worked well because it was still intact when I took the lights down, and the lights were still working properly.

After separating the cables, peeling the used silicone away was easy.

I’d done this treatment for the end plug on the forestay that was raised to the top of the mast, the join with the extension cable at the bottom of the forestay, and the joint of the two strings at the top of the backstays.

Govee H5182 Dual Probe Bluetooth Meat Thermometer

Govee H5182

Because I can’t seem to stop playing with the Govee line of Bluetooth thermometers, when this model came on sale for less than $20 I added it to my Amazon cart.

I knew that the Bluetooth protocol would be different purely based on multiple sensors, but I wanted to play with it anyway. With less than a month since I’d previously figured out a device, I was able to figure this one out in less than an hour, though I still don’t know the battery strength indicator in either this or the H5183 I decoded last month. I’ve added the code to my monitoring program https://github.com/wcbonner/GoveeBTTempLogger/  but have not yet published the changes. The existing code is designed around a single temperature, humidity, and battery reading per device. Even the H5183 broke the model slightly because it has two temperatures, current and alarm, and no humidity. I’m rethinking my data storage to be able to be more expandable, while still being backwards compatible as far as the log files, and will publish the new code when I’ve got it working.

This unit has the advantage of a display over the H5183. It can be used without connecting to a phone at all. You can turn it on, set the alarms, and monitor what’s going on. The one thing I did not figure out how to do using the buttons was to change the display from °F to °C, which I wanted to do to simplify debugging. Using the app I was able to update the settings and view the details.

Details from Amazon:

  • Remote Monitoring: With this wireless grill meat thermometer, you can spend less time waiting and more time multitasking within a 230ft Bluetooth range, Pull out your phone and check the meat temperatures of your grill, smoker, and oven at any time
  • Meat Temperature Settings: Govee Home App offers USDA-recommended food temperatures with various doneness levels for foods such as beef, lamb, chicken, pork, turkey, and more, Grill more efficiently, whether you’re a beginner or a professional
  • Smart Alerts: Avoid the risk of overcooking your food, Once your preset temperature is out of range, your meat thermometer will beep and send an instant notification to your phone via the Govee Home App
  • Food Grade Probes: Our food grade 304 stainless steel thermometer probes have an accuracy of ±1.8°F/1°C to reliably monitor the doneness of your food (under 302℉) ,*Please remember not to touch the probes immediately after use
  • Easy to Place: This Bluetooth meat thermometer has a strong magnetic backing and a folding stand to easily set up on the grill, smoker and oven when barbecuing, There is also a large backlight screen to make it easier to read at night

There is also a single probe version of this thermometer. I expect it works similar to this unit, but the price savings made it less interesting to me since I already have the H5183 in my kitchen.

Govee H5074 and VPD data

I was playing with a couple of brand new H5074 devices and realized that the iOS app now includes two new charts, Dew Point, and VPD.

VPD

The new devices report as hardware version 2.00.01 firmware version 1.00.01. My older devices all report hardware version 1.00.01 and firmware version 1.01.00.

The pressure and dew point are available in both the new and old H5074 devices, but not with any of the other units I’ve got connected. (H5177 or H5075)

I’ve not been able to find details on the data. I don’t know if it’s packed into the BLE advertising data, or only available in the connected download data.

Govee H5183 Bluetooth Wireless Meat Thermometer

GVH5183

I recently came across the Govee Meat Thermometer on sale at amazon and decided to give it a try and see if the communication protocol was similar to any of the other Govee thermometers I’ve bought, the H5177, H5075 or H5074.

The Bluetooth communication protocol is different from any of the other devices I’ve got, but after a day of staring at raw data I was able to figure out some of the details and add support to my monitoring program https://github.com/wcbonner/GoveeBTTempLogger/ . The Bluetooth announcements from the device include both the current temperature and the set alarm temperature. I’ve not yet figured out the battery strength data. The phone app displays the battery, so I know it should be available.

There’s an orange button on one side to turn the unit on. Hold for three seconds. It will beep indicating it’s on. The LED will start flashing green, and the device will periodically send Bluetooth announcements including the temperature and alarm temperature. If you connect to the device with the phone app, the LED will switch to flashing blue, indicating that it’s in a connected state. While the device is in a connected state, it doesn’t not send out announcements. To return it to standard mode, simply exit back to the top level of the app. The app will still alarm when the probe gets to set temperature. Holding the button for three seconds when it’s on will turn it off, with beeps to confirm the change.

A nice feature of this device is that it has a magnet built in, enough to hold the device to the front of a metal oven.

Details from the Amazon listing:

  • Useful Smart Alerts: If temperatures fall out of your preset range, an alarm will sound, and you will get a phone alerts notification via the Govee Home app. The probe measuring range is 0° to 300°C /32° to 572°F. Note: press and hold the orange button for 3 seconds to power on.
  • Convenient Remote Monitoring: Tired of waiting near a hot grill, With a 230ft/70m smart Bluetooth wireless control range(no obstructions), you are free to relax and check your temperatures on your smartphone at a glance. Remember to remove the protective tip before use.
  • Performance Review: Detailed temperature data and easy-to-read charts are generated within 2 hours. (Charts can’t be stored/downloaded) Perfect for a quick review or an in-depth analysis of temperature performance. Improve your cooking and temperature with calibration at ±5°C.
  • Temperature Made Easy: 28 temperature recommendations for 14 types of foods take the hassle out of cooking. Ideal for both beginner cooks and pro chefs.
  • Practical Features: Temperature switching between Fahrenheit and Celcius. (The default unit is Fahrenheit) Mute alarm function and countdown timer on the Govee Home app. The magnetic back can easily be attached to the refrigerator, oven or grill, or any other metal surface. Note: Please keep the meat thermometer unit safe from heat sources and very hot surfaces to protect its internal batteries and exterior shell.

AlaskaAir Safety Placard

I’ve always liked looking at the safety placards when I fly. I’ve only been on two trips during 2021, and the current version in the Alaska Airlines 737 struck me as particularly funny.

During Flight

The character is just so hip. He’s got tattoos, a Sub Pop t-shirt, converse shoes, drinking coffee and reading a book.

Oxygen

The oxygen deployment demonstration shows that it’s cool for dads to be taking their daughters on airplanes. It’s also implying that kids like airplanes and are more likely to be engrossed in a toy airplane than whatever is causing the masks to be deployed.

Prior to taxi, takeoff, and landing

There are so many things to love about this picture. The guy standing has a puffy coat. The woman has a laptop covered in stickers. The other woman is carrying a Starbucks coffee. The follicaly challenged man is wearing cuffed trousers and boots. Everyone pictured is narrow and fit looking. The amount of knee room between the seats compared to a real airplane just seems cruel.

Lewmar Wired Windlass Remote

When I purchased my sailboat one of the items that came up on the survey was that the windlass control was missing it’s button covers. Recently when I was preparing to drop my anchor, the controller would allow the anchor to be lowered, but not to raise it. The buttons had finally failed.

I searched around online to find a replacement. I found several places with the exact model controller for over $150. Looking at the Lewmar site, I was able to find a newer remote, and when I searched for it’s model number was able to find it available for significantly less than the original. It appeared to have a similar plug, and claimed to be universal.

Lewmar Wired Windlass Remote – 66940002
Lewmar Wired Windlass Remote – 66940002

I was pleased to find that the three conductor plug on the new model mates directly with the old socket. That meant that I simply had to plug the new remote into the existing socket on my boat, and store the socket that came with the new remote with the rest of my spare parts.

The new remote is definitely an improvement, being smaller and properly water resistant.

Details from Lewmar:

Raspberry Pi GPSD with Pepwave MAX Transit

I’ve been wanting to do some GPS data programming with the Raspberry Pi that’s on my boat. The Pi is connected to the NMEA 2000 network, and so should be able to retrieve GPS coordinates from either my chartplotter or my AIS unit when they are powered on, but it should also be able to get the GPS data from my Max Transit cellular gateway device.

It turns out that configuring gpsd to retrieve the data from the max transit was fairly easy. I edited the file /etc/default/gpsd to include the internal address and port of my router and restarted gpsd and now the Pi has the correct location.

/etc/default/gpsd

The devices section was initially empty. I added tcp://192.168.50.1:60660 between the pair of double quotes. After that, I was able to run gpsmon with no parameters and it connects to the local machine and reports the gps statistics.

gpsmon

I’d verified that I can read the device directly over the network with the command gpsmon 192.168.50.1:60660 but I wanted to be able to write my programs without needing to know where the gps was located.

Garmin vívoactive® 3 and raceQs sailing tactics app

Garmin vivoactive 3

I purchased a Garmin Vivoactive watch to be able to run the raceQs sailing tactics racing watch app. I’ve actually purchased two of these watches. I purchased the first in early 2020 when I saw it on sale for around $120 on a discount site. I used a little bit with the RaceQs app https://raceqs.com/smart-watch/ before the COVID-19 Pandemic shut down all sailboat racing, and then used the watch more for its built in GPS bike tracking and walk tracking features during the summer. Towards the end of the summer when I was getting back into sailboat racing, I was wearing the watch on my right hand and managed to knock the strap loose while tying fenders to the lifeline. The watch bounced once on the deck before going overboard. It took me a few months before I saw another deal online that convinced me to buy a second watch.

Fitbit Charge 3

I have a long data history with Fitbit, and currently wear a Charge 3. It’s similar to the newer Charge 4, but without the GPS tracking features. I like the smaller profile on my wrist of the fitbit, and have been wearing it or something similar 24 hours a day for the last five years. The larger size of the Garmin makes it harder to convince myself to switch to away from the Fitbit for my general data tracking, when though I’ve learned that when I don’t use the GPS features of the Garmin it has similar battery life to the Fitbit. I like the always on watch face of the Garmin, especially after I picked an analog style watch face.

Garmin Titanium Watch Face

I like using the RaceQs app on the watch while sailing, especially with the more recent editions features of automatically uploading race data to the website. I have some issues, that I mainly believe are because of the touchscreen abilities with the garmin watch. I believe that the app would be much better served on a watch with an array of buttons surrounding the watch face. The pictures of the app on its website appear to show a button centric watch.

The way I use the watch for sailing is that I wait till I’m on the boat, preparing for a start. Then I start the raceQ app on the watch, wait for it to get a GPS fix and go to the timer setting. Then I configure the timer for the appropriate countdown to my start and start the countdown. Then I explicitly press and hold the crown button until I can press the lock icon, locking the touchscreen. I’ve found that if I don’t lock the touchscreen, inadvertent touches will change what’s displayed on the screen, and cause the app to change modes. I do my best not to touch the app until after my race has completed.

Sometimes I notice the app is on a page that asks if I want to exit, with a check (✔) or cross (❌) option. I’ve found that the best option is to not enter anything until after the race has completed.

I wish that the raceq screen displayed GPS time on all screens, including the screen asking if I wanted to exit the app. There are plenty of times that I’ve been hiking on the rail and the skipper wants the exact time recorded for when we’ve crossed the finish line. with the watch locked, there’s no way to get the time on the watch quickly.

The app automatically calculates tacking angles to the mark after one set of windward/leeward marks have been rounded, which seems nice, but in my position on the boat, isn’t as important to me as the start timer, or the real time of finish.

I don’t know if there’s a way of creating screen shots of the watch display similar to what’s on a phone. It would be nice for describing after the fact what was going on, but with the limited storage and buttons on the phone, don’t expect there’s a way of doing so.

B&G Zeus™ 3S 9 Memory Card Update

In my previous post I was not able to use the 32GB memory card, while the 16GB memory card worked.

Lexar 32GB Flash Card Properties

I’m happy to report that after explicitly formatting the card as FAT32, my chartplotter was able to read and write the card correctly.

I don’t know the underlying platform the chartplotter is built on, but with flash card sizes regularly increasing, I’d hope that B&G introduce support for the exFAT filesystem in the future. https://fossbytes.com/linux-5-7-microsofts-exfat-driver-code/ has a nice description of the inclusion of exFAT in Linux.

B&G Zeus™ 3S 9 Vessel Message Alarm

Vessel message from: 541064663

This is a feature that I’m still trying to understand. I believe it is an AIS message, and possibly a distress message, but have not been able to figure out what it means. I get the same result whether I push Show or Close, in that the alarm dialog closes and no cursor is selected.

Garmin AIS 300

I have a GARMIN AIS™ 300 Blackbox Receiver connected to my NMEA 2k network, and assume that it generated the message on the local network and the B&G is just displaying it. Because I don’t have an AIS transmitter, I don’t believe it’s a directed message to me. I’m not broadcasting any ID, and my radio isn’t hooked to the GPS, so isn’t configured to be able to broadcast distress signals. (One more item in my to-do-list)

The only annoyance I have with this type of message has been when I left the instruments running while i was away from the boat and returned to find the alarm beeping and a similar message displayed. I don’t like that the beeping may have been annoying my neighbors for days.
