I design things for fun and a living. I play with everything from submarines, 3D printers, airplanes, and electronics.

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.

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?

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.

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.

@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.

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.

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.

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.

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.

Using two tools to help me with holding the sheet metal and aligning it for the laser.
The most visible tool is the one from ComMarker itself. Here is the link to that: commarker.com/product/comm...
The second one is an X, Y, Z table that I got from Aliexpress:

My most recent laser 0.2 module gears 0.8mm thick.
ø9.4mm - 45 teeth
ø3.4mm - 15 teeth
I was also able to remove them from the frame and confirmed that they mesh.
I still need to make some minor changes on the process, but custom gears in about 30min.

Good catch! I am wanting to be able to inspect my tiny laser creations like this with features under 0.0027" (0.07mm).

What are people using for lower cost digital microscopes lately? Thinking about getting the TOMLOV TM4K-AF Max. Main use cases are electronics rework and visual inspection of features under 0.001" (.025mm). Willing to spend up to $450 if there are substantially better features.

I went small with the laser. I got the features to 0.008" (.2mm) down to 0.004" (0.1mm) very successfully. From there, I tried to go down to 0.002" (0.05mm). The second picture is the best I could get on my current setup. I might be able to do better with a 70mm lens vs 150mm.

I am excited about this. This is the first engineering part that I have made on my ComMarker 60W MOPA laser. It is about .010" thick, and with deep engraving, it made it through in 3 passes. I am very happy with the result. Now I need to finish my laser enclosure for it.

You should recreate my Resin Printer Workstation. It makes resin printing cleaner and more contained.

I "upcycled" our small, Ikea kitchen table. Originally intended to be a temporary table while we moved, but ended up being around over a decade while our son got older. The legs were fine, but the top was falling apart. Bought a piece of granite and then hand polished the edges.
