In today's what the heck does Adam do while on vacation adventure. Some FEMM action. Trying to reduce cross talk between two magnetic encoders in a tight space. The results show the difference between the magnets both pointing right, or being anti-aligned.

Please tell me that I am not the only one that goes on Aliexpress just to see what neat things that I had not even considered buying!

Perfect alignment every time. Upgraded my ComMarker B6 with a digital scale to take the guesswork out of defocusing. Use the focus cone to set true zero then dial in exact, perfectly repeatable offsets for color engraving. #LaserEngraving #3DPrinting #ComMarker #MOPA

I wish that there were more details on this boat, though I do have a few other photos, there are not many that I know of that exist.

Calibration complete. The first picture, I was dialing in the settings to make a mark light enough to get a nice distribution. I made an adjustment. I then checked my adjustments as shown in the second picture, and got it dialed in.

Built a focal calibration tool for my ComMarker B6 MOPA laser! 🎯 • Right: Level plane for quick coarse focus. • Left: 5mm sloped ramp with 50 divisions to micro-tune focus down to 0.1mm precision.

Aeroengineer1 @aeroengineer1.bsky.social · 30/07/2026

I wanted to bring some more precision and accuracy to doing color laser engraving with my ComMarker MOPA laser. I got a vertical axis digital scale to be able to calculate deltas more easily.

My son and I have been experimenting with the ComMarker B6 60W MOPA fiber laser today, working on...

And now the third Hesai Lidar is functional. This makes for one Hesai 64 and two 128's.

040

Aeroengineer1 @aeroengineer1.bsky.social · 19/05/2026

I have my second lidar up and running. This is the Hesai Pandar QT128 up and running. I had to use Wireshark to find the IP address of this one, but it is working very nicely.

Here in my local area they have created a fantastic commemorative park and pavilion of the decommissioned USS Cincinnati, a Los Angeles class attack submarine.

040

Aeroengineer1 @aeroengineer1.bsky.social · 30/03/2026

I am now working out a plan to do a LIDAR scan of this submarine outside of the Submarine Force Museum in Connecticut. It will include modifying a fishing reel with a motor to drag the unit along automatically.

Aeroengineer1 @aeroengineer1.bsky.social · 28/03/2026

It is alive! Hesai PandarQT 64 LIDAR viewed through @kitware.bsky.social 's LidarView. I need to start playing with this more to see how I can do some mapping of large structures and what things influence the overall precision/accuracy of the measurement.

Aeroengineer1 @aeroengineer1.bsky.social · 21/03/2026

Anyone have experience with Velodyne Lidar unit repair? I have a VLP32C that I got of ebay. It spins up, my webcam can see the lasers shining on the walls, but it does not communicate over ethernet and there are no activity lights on the ethernet port.

010

Aeroengineer1 @aeroengineer1.bsky.social · 16/03/2026

I may just go with this. It is the right size, I can make it semi surface mountable, good price, and good documentation.

110

Aeroengineer1 @aeroengineer1.bsky.social · 16/03/2026

I can just use this, but I was hoping that there was something more elegant. I see so many that have everything and the kitchen sink, but still want external components.

Aeroengineer1 @aeroengineer1.bsky.social · 16/03/2026

Anyone have a favorite surface mount power module? Requirements: -SMD -No other components required for functionality (no resistors, external caps, filters, etc) -5v, 500-900mA output -12v input

Aeroengineer1 @aeroengineer1.bsky.social · 15/03/2026

Sorry to hear that walking is difficult for you. I am interested in trying to see if anyone might be able to go and look at a boat that is not at the museum but nearby. It is the Kairyu that is near the Naval Training Center. I am particularly interested in locating the Kingston Valve and piping.

Aeroengineer1 @aeroengineer1.bsky.social · 15/03/2026

As for why the Pearl Harbor boat is described as Ha-19, it is because the report that came out just a few weeks later used No. (number) 19 in the report on the boat. www.ibiblio.org/hyperwar/NHC...

Aeroengineer1 @aeroengineer1.bsky.social · 15/03/2026

I have attached pictures with dimensional markings on each picture in US Customary units of Feet and Inches.

Aeroengineer1 @aeroengineer1.bsky.social · 15/03/2026

Sorry, I meant to put Ha-51 for the Guam boat. I have included pictures before its horrendous "restoration".

Aeroengineer1 @aeroengineer1.bsky.social · 15/03/2026

Late reply, but here are pictures of the boat on tour around the US during the war. It was setup such that they could rotate the boat around its long axis for ease of transportation. When on site, they would rotate the boat upright and set up stairs. Viewing windows were cut unto the hull.

Aeroengineer1 @aeroengineer1.bsky.social · 15/03/2026

Here are a few other views of the boats that were in the drydock prior to destruction. You can see a few different configurations of the Type D, as well as a few different configurations of the training boat. There appears to also be at least one Type C in there as well.

I am reprinting a lampshade that I designed almost 8 years ago. This time I printed both pieces in PETG with a 0.8mm nozzle. The first time, the clear was printed in PLA and at 0.4mm. The green PETG was still wet despite drying it, so I will need to reprint it.

Aeroengineer1 @aeroengineer1.bsky.social · 26/01/2026

It is hard to choose just one, but I will put the YF-23 in the mix.

Aeroengineer1 @aeroengineer1.bsky.social · 04/01/2026

What can you do for ~$3 in filament? Custom print a shelf to hold your NAS, Router, and Doorbell Base Station. Over Christmas break, I was able to clean up all of our wireless networking space such that it is a much cleaner installation and in a better location for speed and space utilization.

Am I the only one that uses drawing to maintain focus during classes or talks? I find it helps me to focus on what is being said while being able to ignore other outside distractions. This was my latest sketch of my Santa hat and an ornament on a wood floor.

Aeroengineer1 @aeroengineer1.bsky.social · 27/12/2025

If you are interested, here is the basic assessment that I did that brought me to this conclusion. The numbers are not perfect, but I do believe that it shows that there is at least one side that has either a missing or displaced door in relation to the other side.

010

Aeroengineer1 @aeroengineer1.bsky.social · 26/12/2025

After looking at the pictures, it appears that the most forward tube on each side is staggered, not side by side. This would also help understand the door to door spacing on each side not being closer. Here is what my crude top down estimate is for the configuration.

Continuing with my concept development for an RC 1:72 @BMT_Defence SSGT submarine. I have found a clean path for wiring as well as making the fins and propulsor shroud separable. The only compromise is using externally visible fasteners for the shroud.

080

Aeroengineer1 @aeroengineer1.bsky.social · 28/11/2025

Today's efforts. BMT Defense SSGT concept had a rotor between structural components. Challenging for a 1:72 model! Needs to be: -Structural -Separable for assy and maintenance -Pass wires for control -Water tight Not a trivial task. Grey bar 1" x 5" (25.4mm x 127mm) for scale

020

Aeroengineer1 @aeroengineer1.bsky.social · 28/11/2025

Had fun over the last few days laying out a hull plane installation for an RC model of the BMT SSGT concept from a while back. I have three different models that will all need an installation like this. I find PowerPoint is a great tool for quick layout.

Sometimes it is the small things. I was able to design cup and handheld scanner holders for forklifts for some friends. Here is the latest batch for them. About 18hr and 750g of ABS for two sets.

070

Aeroengineer1 @aeroengineer1.bsky.social · 27/09/2025

Anyone know where I can get a used Hesai connection box and cable for the QT128 devices that I just got off ebay? Conversely, anyone know of a good Automotive Ethernet (1000BASE-T) to standard ethernet converter for a good price?

110

Aeroengineer1 @aeroengineer1.bsky.social · 27/09/2025

When I go ebay sniping I win... 3 for 3. Now lets hope that one of the three is serviceable. What am I going to do with three lidar units you might ask...? Well that is a great question. In the words of the wise Tevye, "I don't know"...

Aeroengineer1 @aeroengineer1.bsky.social · 23/09/2025

I am back on the microscope project. First up, putting the mount ring on the lens adaptor. It was ~ø1mm too big & needed a hole for the lens release button. 3D printed a shim & used my 60W fiber laser to cut through the ~5mm thick AL to expose the lens release button.

060

Aeroengineer1 @aeroengineer1.bsky.social · 23/09/2025

@hackadayofficial.bsky.social the hackaday.social site has not been working for me for a while now. I am not sure of the best way to report things being down except through a different social media site.

Aeroengineer1 @aeroengineer1.bsky.social · 25/08/2025

This weekend parts came in for the microscope build. Reusing a motorized lift that was a replacement part for my laser that did not end up being used. Coupled to a geared lens positioning system. Then attached to a mount ring. @ubermeisters.bsky.social @gregsaunier.bsky.social

Aeroengineer1 @aeroengineer1.bsky.social · 24/08/2025

Mine is still where I want it, but it has gone to the point that it is hidden before for me.

Initial test shots. iPhone 8 as the test subject. The iPhone screen has a 326ppi resolution. The lens was approx 6" (150mm) away from the screen when taking the picture.

Aeroengineer1 @aeroengineer1.bsky.social · 17/08/2025

Working to get my Canon 100mm Macro lens working with the Pinefeat adaptor. So far so good. I have gotten through the calibration, now to get that into the file so that autofocus can work.

Aeroengineer1 @aeroengineer1.bsky.social · 14/08/2025

Can't say that I have seen this before. Upload much faster than download. Down is supposed to be a Mb connection, but something is up.

This time under the microscope is a brass gear. It is ø9.4mm, 0.2mod, 45 tooth gear. Each tooth is about 0.4mm tall. In this method, I used a cleaning pass to remove oxides off the surface. That produced a very interesting stippling effect around the cut.

Aeroengineer1 @aeroengineer1.bsky.social · 10/08/2025

Helps if I put the correct picture in

Aeroengineer1 @aeroengineer1.bsky.social · 10/08/2025

Any of my Cincy friends have a Canon EF 100mm f/2.8 Macro USM lens that I could borrow? Will be used indoors under very controlled conditions. I want to see how it will work as a digital microscope lens when paired with a Pinefeat adaptor to the RasPi High Quality Camera sensor.

Aeroengineer1 @aeroengineer1.bsky.social · 05/08/2025

New digital microscope came today. First look is at a tiny encoder that I cut on my laser. The windows are .0027" (.07mm) nominal sized. Some things that immediately jump out are the surface oxides and potential remelted. This view gives me ideas on future process improvements.
