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.

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.

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 @ComMarker113902 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.

Forced upgrade to Win11 on my main box. Not a Windows basher, but really don't like the @Windows 11 workflow. There are some nice features, but they are more than offset by the forced lack of customization. Going to try StartAllBack to add back the custom features.

Note that when I said hand polished, I meant, I held an electric polisher and put about 3 hours into polishing the edges (and adding a small bevel at the top) and then followed all of that with a hand buffing of the edge to seal it.

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.

Anyone wanting a LSM6DSV16X breakout board, I recommend direct from ST Micro vs @sparkfun. It is cheaper, and comes with 2 other sensors. It also took me 2 orders of incorrectly shipped parts before I gave up and found the direct option from STM.

Finally able to get @ST_World MEMS Studio up and running. I am planing on using the LSM6DSV16X Accelerometer and the LPS28DFW waterproof pressure sensor for my current RC submarine effort. This tool will allow me to refine the sensor register settings and then import to my code.

Sorry for the double post. I am doing a test for what time to post things.

I am also going to add blank-off panels to the left and right of the Wash & Cure station to give it a more finished look. I also am going to add a 3D printed cord management system in the back to manage the cords better.

I made a workstation for my @anycubic3dprint printers and Wash & Cure station. The Wash & Cure station pulls out so you reduce dripping on the floor when moving models from the printer to wash. There is a power strip on the back and I will add one to the front for support tools.

I had a steering bushing break on my lawn tractor. I decided to have a bit of fun and do a 3D scan and then convert that into a 3D cad model. Tomorrow I will print it, install it, and then mow the lawn.

I would also be interested in an MP6570 and 6541, but I was having such a pain just getting the brushed components that I gave up on trying for these :).

Do you know anyone that has all 4 items at list price? I was trying to get a few samples of the parts, but it did not like the email that I use for my hobby business. I understand if this is not possible, but the answer is always no if you do not ask.

New hobby project. Doing some sensing and motor control stuff.

I print a glider today on my @BambulabGlobal H2D. It is printed from ASA. I am going to try ASA Aero next as well as making it in a larger scale. It flew well.
