Brian Hughes will be towing Harold, a K-350 Psub from Maryland. Brian's boat, Harold, is a two man K-350 boat so will be available to take passengers for the science objectives along with Gamma. Jon Wallace has agreed tentatively to be the Surface Operation Coordinator (SOC) for the Expedition. Sean Steveson is coming to help with dive/rescue support. If you have changes to the roster, please update them in the roster file in the Dropbox folder. At this point the FLBS research boat will tender Gamma, and Josef Crepeau's boat will tender the R300.

Brian Hughes will be towing Harold, a K-350 Psub from Maryland. Brian's boat, Harold, is a two man K-350 boat so will be available to take passengers for the science objectives along with Gamma. Jon Wallace has agreed tentatively to be the Surface Operation Coordinator (SOC) for the Expedition. Sean Steveson is coming to help with dive/rescue support. >>> >>> If you have changes to the roster, please update them in the roster file in the Dropbox folder. At this point the FLBS research boat will tender Gamma, and Josef Crepeau's boat will tender the R300. We still need to identify a tender vessel for Harold. >>> >>> Best regards and a happy new year to all >>> >>> Cliff Redus >>> >>> Great works are performed not by strength but by perseverance.

Use these instructions to get it working: https://www.electric-skateboard.builders/t/vesc-monitor-android-app/20888 It uses a cheap "HM-10" bluetooth module, like this one: https://www.ebay.com.au/itm/AU-2Pcs-BLE-Bluetooth-4-0-HM-10-AT-09-CC2540-CC2541-Wireless-Transceiver-Module/153251503984?hash=item23ae805f70:rk:1:pf:0 See how you go and I can help with troubleshooting if needed. The Metr/Perimetr apps which go with the expensive dongle are excellent and the dongle well worth the $$$ for testing. You can change the VESC configuration/settings and even do firmware updates apparently (I am running custom firmware) via bluetooth this way - saves a heap of messing about opening housings, etc. Cheers, Steve (the Aussie one) On Tue, Jan 1, 2019 at 9:42 AM Alan via Personal_Submersibles < personal_submersibles at psubs.org> wrote: > Jon, > thanks, it is using a 10K NTC thermistor but the power to it runs through a > small pcb in the motor that is also used by the hall sensors.

I managed to get one of my 3 bluetooth modules up & running & sending data from the Vesc to my phone. I can see motor temperature but Can't see Vesc temperature. Above mot. there is max! The max temperature is similar to the motor temperature; is this a record of the max temperature the motor has gotten to, or default because I haven't put in any settings yet, or is the max meant to be the Vesc temperature? Also there is a little drop down at the top ( in picture "esc monitor now") that I can't seem to get rid of & are not sure of it's meaning. There seems to be a vibration happening, again this may be an alarm because I haven't put in any settings. Have attached a couple of screen shots. Any thoughts would be appreciated thanks.

Very fast & foam temporarily caught on fire a number of times. I got it in the ball park with the hot wire then used a wire brush & a rough grade sand paper to finish. If you use the wire too hot the polystyrene surface gets a plastic sheen that makes it harder to work with the brush & sandpaper. I once made a 1/4 size polystyrene ambulance mainly using an electric chainsaw. With the chainsaw you need an area to contain it as it is really messy.

Are you saying to bend (form) the aluminum flashing to the shape I want the styrofoam and then draw a hot wire along it to set the cut in the styrofoam? The flashing must have to be rotated after each pass with the hot wire from 9 o'clock over the top to 3 o'clock to get the proper shape and radius for the mold so how do you rotate the flashing plus the flashing has to pivot on a predetermined axis dependent of what shape you want so you would have to somehow remove the styrofoam without the hot wire to attach the formed flashing to the pivot points on both ends of the styrofoam block?

Many years ago, I drove over the US border on a dive trip, having already mixed gas in several cylinders I was traveling with. Customs officers made me drain them all and spin the valves off so they could take a look inside to ensure I wasn't smuggling drugs or something. Maybe I look shady? Anyway, it was several hundred dollars worth of heliox. I'd rather not repeat the experience. Much better to partial-pressure mix and air top with an on-site compressor, if the option is available.

One advantage is that you could "flip" the templates & get an exact copy on the ballast tank on the opposite side. I am thinking you could cut the templates out of thin sheets of board scaled up from sections from your cad program & glue them to the ends of the foam. Some polystyrene suppliers have the ability to cut the standard block to your design which saves you a lot of work. My local firm is limited to cutting it in 2 dimensions, but it is a good start.

(It might take a couple of pieces), depending on the lenght of your arc. Two sets will need yo be made. Then either barge cement the arc to each end of your foam block, or hold in place with screws. Then draw the hot wire against the form. On large pieces, this process best works with two people, or a large bow wire cutter where you can feel the wire agsinst the form as you pull the wire through the foam.

Don't understand. Are you saying to bend (form) the aluminum flashing to the shape I want the styrofoam and then draw a hot wire along it to set the cut in the styrofoam? The flashing must have to be rotated after each pass with the hot wire from 9 o'clock over the top to 3 o'clock to get the proper shape and radius for the mold so how do you rotate the flashing plus the flashing has to pivot on a predetermined axis dependent of what shape you want so you would have to somehow remove the styrofoam without the hot wire to attach the formed flashing to the pivot points on both ends of the styrofoam block? >> Rick >> >> >>> On Sat, Jan 5, 2019 at 8:39 PM David Colombo via Personal_Submersibles wrote: >>> Hi Rick, use aluminum flashing that you buy from the hardware store as the form cut to shape on both ends of the foam block.

As I am ready to purchase them, What would you recommend ? I was planning on placing them on the inside and outside of the thru hull plates as a redundant seal, so I would be looking at needing 52 of M20x1.5 As I am having a difficult time sourcing them here in California, would you be interested in being a source supplier?

You're boosting 12 VDC to 24 VDC with some sort of DC-DC converter? What is your 12 V source? The boat battery? Engine running may actually be better in that scenario, because the battery should be charging at higher than nominal voltage. Once you shut the engine off, you're relying entirely on the chemical potential of the battery, which could fall below nominal quickly if it's nearing the end of it's useful service life. Check the voltage with a multimeter, both upstream and downstream of the converter. If that is the culprit, the best way forward is probably to replace the engine alternator with one which outputs 24 Volts, use two 12V batteries in series, and eliminate the converter.

I commented before on this that if you are hearing the signal clearly but very quiet in the sub that it could be a problem with the amplification in the sub's unit. With underwater coms do they become distorted or quiet or both at the edge of their range? If distortion is a factor then it would indicate that the amplification in the sub's unit is the problem.

Photo shows 48V battery pack in battery box, with an oil compensator, speed controller in plastic box & red servo tester ( speed input ) on top of it. The servo tester is wired to the speed controller & turns the pot input into a 2.4ghz signal. I knew this would be the weak link as it was a cheap unit that I had previously had trouble with. Possibly the loose pin connection in to it. I had trouble from the start & swapped to my backup which was a radio control transmitter & receiver. I was running the brushless motor on sensorless mode. This means the commutation is sequenced based on position feedback from the motors back emf. This wasn't working well on high speeds & was jumpy or stopping completely as it lost it's sequence. All my motors (11) have hall sensors for sensored control but I had problems setting that up in the computer program so ran without it as I wanted to get on the water. The speed controller operates on both so the "not so good" sensorless control is a back up if a sensor fails. Speed controller temperature got up to 75C, it has an over temperature function that backs off the power at 80C, so I stopped to let it cool. I did have heat sinks glued to the top of my battery box to mount the controller on, but when I set up at the beach I found I couldn't reach that position as the wires weren't long enough :( . Highly recommend that any motor controllers have good heat sinks or are heat sinked to the hull as it will increase their life or save them from failing. Was followed by a small stingray for a while so am thinking the motor may put out an attractive vibration to them! The thrust was good & I am intending to have 4 horizontal thrusters, so should speed along. A few things to work on before my next outing.

I had read that the top of the propellor blade should be at least 12" below the surface & this seemed to be about right. I will lift it up a bit & see how it goes next time. I am wanting to mount the horizontal thrusters as high as possible to keep them as far away from the sea bed as possible when I'm on the bottom. Getting them at the right height may take some in depth calculations of weight & buoyancy.

When running engines in either mode, the engine output shaft may be connected to propulsor shafting directly for maximum efficiency, or as is more typical, directly connects to electrical generator(s). The AC power output of the generator(s) is then rectified to DC and used to charge the batteries, or to power the DC electric motor(s) that drive the propulsor shafting, or both, depending on operational requirements. When submerging, the engines are stopped, the air induction shafting is closed and mast(s) retracted, and the batteries alone power the electric motor(s) on the propulsor shaft(s). This pure electric mode of operation is near silent. Diesel-electric boats are quieter than nuke boats when running submerged for that reason, absent a number of elaborate and very expensive mitigation measures. Power from the batteries is also drawn off for vessel system and hotel loads, so when the available battery power is low, the sub needs to surface in a safe place, or ascend to snorting depth in a safe-enough place, and run the engines to recharge the batteries. That's it in a nutshell. Sean ??????? Original Message ???????

The motors were run backwards by the diesels and generated the electrical power to recharge the batteries. Is this still the case in modern diesel-electric submarines, or are alternators now used to recharge the batteries?

I hope to use electric valves. The varible ballast is a worm drive 100# weight internal under my battery area. The external mbt will all be molded fiberglass shapped around the ribs between the pressure hull and exoskeleton, with the exoskeleton being one side of the tanks.

I am planing to have both forward and aft tanks on each side, so you just saved me two valves. I like the idea to be able adjust for and aft, since they are different shapes and volumes. I am also planning to have the side tanks on the larger volume to be made up of 4 chambers that would prevent sloshing except in each 12" wide section.

I have assumed a front pilot weight of 200lbs in my design. For increased weight above the 200 I have a system simular to the snoopy with the trawler floats that I can add. For lesser weight I have a rack design to recieve dumbell type weights that would be added under the pilot seat that can be easily adjusted for different passengers. In addition to the internal trim weight, which is a sliding rail system. I have also decided to reserve one mbt located at the cg line to be controlled independent of the other mbt for the additional control if I need it.

The only problem about using a MBT near the CG as a VBT is that it is soft with an open flood port.? As such, it would be like a scuba divers BCD and require tweaking as you change depth.? I think better to used your added dumbbell weights at CG as your primary variable ballast and keep all the MBT flooded when diving then you don't have to correct for decreasing buoyancy with depth. Have you calculated your Reserve of Buoyancy (ROB) for the boat assuming you use all the MBT for freeboard?? Should be pretty good.

I had deliberated on the worm drive for trim but in the end bought a 36V corrosion resistant water blaster pump to adjust trim & ballast. This would have been good in your case as you could have replaced your passenger with a flexible bag that you could pump water in & out of.

Introducing Ping and upcoming events! View this email in your browser Newsletter - January 29, 2019 Hi friends! Happy 2019! We hope everyone's year is off to a smooth start! We have lotsss of new products in store for this cycle around the sun, including one that many have been eagerly anticipating. We also have some news on a few upcoming events and a video to share about curiosity in robots. The New Ping Sonar Altimeter and Echosounder The new Ping Sonar is a multipurpose single-beam echosounder. It can be used as an altimeter for ROVs and AUVs, for bathymetry work aboard a USV, as an obstacle avoidance sonar, and more. The Ping combines a compact form factor and 300 meter depth rating with an open source user interface and development libraries to create a powerful new tool for marine robotics! Read more... First Ever Open House! As many of you know, the Oceanology Americas show is taking place at the end of next month (25-27 February) down in San Diego, California. Since it's so close, we are taking the opportunity to host our first official Open House! Our location is about 120 miles or a two hour drive from San Diego. If you will be in town that week, we would be thrilled if you could join us! Address: 2740 California St., Torrance, CA 90503 Date: 28 February 2019 Time: 12-4PM We plan to have ROV demos, Crushinator demos, Water Linked demos, tours, food and drinks, order pickups, and lots of socializing! Please RVSP by 8 February! RSVP! More New Products BLUART USB to Serial and RS485 Adapter The BLUART USB to Serial and RS485 Adapter is a tiny circuit board capable of interfacing with devices using serial UART or RS485 communications protocol and converting the signal into USB for connecting to a computer or Raspberry Pi. It works great with the Ping Sonar and we recommend it for getting started! Micro-USB to USB-A Cables These little cables are great for connecting small things to other small things inside small spaces. We're releasing a left angle cable (used on the BlueROV2) and a straight cable. Updated BlueROV2 Components The new Stainless Steel Ballast Weight is a drop in replacement for the original lead weight. We've also repackaged the Moisture Indicating Silica Gel so they come prepackaged in 6 individual bags. All new ROVs will come with these upgrades! What if robots became curious? ? Researchers at Woods Hole Oceanographic Institution believe they can be! Their goal is to train robots (like the BlueROV2!) to be able to search and spot the strange and the beautiful, so the next time they see something unexpected, they follow it. Check out the full video. Upcoming Events Oceanology International Americas 2019 This year we're exhibiting with our friends Water Linked in booth J31. Since it's so close, we'll have lots of our humans in attendance! Ocean Business We're looking forward to our return to Southampton, UK this spring for Ocean Business 19. Come visit us at booth V13!

It runs off 5.5V & draws 100milliamps so not very high powered. As it's in development I will email them & see if they intend to increase the range! At least it has a depth rating, which is something I have had difficulty in finding with boat depth sounders. As it is it could be good value for collision avoidance.

I tried several times to find info on transducers. I talked with people involved in developing boat based sonar systems over here, who inquired with the transducer manufacturers in Europe. They didn't know the depth rating. A few thoughts are "will the signal need any calibration shooting through fibreglass", & will any flexing of the fibreglass under pressure effect the signal. Be good if you could test it against a sonar on your support boat. Another thought is "are all transducers the same".

Alan Hi Alan, Thank you for the email and your interest in our new Ping echosounder! We are planning to make a longer range echosounder in the future, but we don't yet have an official timeline. Is there a specific range you are looking for? The following specifications were important in our current design and had an impact on the maximum range: 5 V input voltage and low power consumption 30 deg. beam width for effective obstacle avoidance Small and light weight 115 kHz frequency to reduce interference from the typical 50 kHz and 200 kHz boat echosounders Thanks again for your interest in our products and I look forward to hearing back from you.

As an altimeter, range outweighs input voltage or power consumption.? I would suggest 12vdc input voltage and range of 300m would cover 99% of PSUB applications.? Output should be serial. However, I think they are pushing this as obstacle avoidance and altimeter capability is just "free" information that comes with that technology.? The price of a commercial depth finder like Humminbird HDR650 with 600 foot range is only $120(US) so if altimeter is the goal instead of sonar imaging, they may not be able to compete from a pricing perspective. Having said that, it does look like the "ping viewer" would interface with a Raspberry Pi, which in my case for example, means I could add it as a separate display window in my SCM interface.

The first is in surface transects.? It is nice to see the depth under the boat and particularly when you get near the dive site.? For this case the max depth is associated with the max depth capability of the Psub.? With a sounder, you can have a NOP that calls for never doing a surface transect over a bottom that is deeper than the design depth of the boat.? This assures that if the boat goes negative in an uncontrolled descent for any reason, the boat would hit bottom within the design parameters of the boat.???The second is when you are in the water column out of visual contact with the surface and the bottom and want to know how quickly the bottom is coming up on a decent.? Having a display of altitude is very comforting when diving under these conditions.? So to me knowing the depth during a surface transect is the more difficult measurement and would set the maximum depth requirement.? So something on the order of 200m would cover the vast majority of psubs.??

Thank you for the email and your interest in our new Ping echosounder! We are planning to make a longer range echosounder in the future, but we don't yet have an official timeline. Is there a specific range you are looking for? The following specifications were important in our current design and had an impact on the maximum range: - 5 V input voltage and low power consumption - 30 deg. beam width for effective obstacle avoidance - Small and light weight - 115 kHz frequency to reduce interference from the typical 50 kHz and 200 kHz boat echosounders Thanks again for your interest in our products and I look forward to hearing back from you.?

I am going off the idea as I had a quick search & found a low end fish finder & transducer for US$96-. It has a 500ft range. https://www.marine-deals.co.nz/lowrance-hook2-4x-fishfinder-with-bullet-transducer By using a transducer that can shoot through a hull, it would be able to shoot through a fibreglass pressure resistant housing as Hank is about to do.
