Anyone know where I can get a used @HesaiTech 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? Perhaps @Ascii211 might have a lead?

Ok I actually have some fun and great ideas to play with lidar odometry for 3d mapping of data points. These devices will allow mapping of large objects that could not be done with my smaller 3d scanners. I plan on using this with Robot Operating System

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"...

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.

@ubermeisters @MisterHW I now need to make a base, make an adaptor for the geared lense positioning system to the lift arm, and design an enclosure/attachment for the Raspberry Pi and camera wiring.

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

I am really happy with the results so far. This week I need to start designing a stand for this.

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.

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.

Some views from the cabin we went to this week. It was a blast to be away and a little closer to nature.

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.

Feel free to reach out if you do projects like this at home.

The second is that I am always looking our for people that do the same sort of tinkering at home. I have come to learn that I am a bit unique in this aspect. Finding and connecting with others that do the same helps create a larger group of connected, self-guided learners.

As an aside, I post these updates with two purposes. The first is to show people that there is a lot of exploring that can be done at home. Through this exploring there is a lot of learning that can directly be translated back into application in the workplace.

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.

Well it seems that I am just going to have to bite the bullet and get one tonight.

It helps if I put the correct picture in

I want to try the lens before I buy one.

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.

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.
