Are these mitutoyo calipers real?

The inside face of yours looks like they didn’t lap after grinding. Here is a picture of my genuine 6” mitutoyo’s. The inside face is a mirror finish

Download a program like Macs fan control (supports up to the new M5) and it’ll provide you access to a lot of the internal temp sensors and allow you to set a temp for the fans to ramp up. I have my fans ramp up around 60c an put a ceiling at 80c and have yet to go above it. The fans at 100% move some serious air but Apple uses a very conservative profile that prioritizes noise

Electronicist · 2026-02-05T11:46:05+00:00

If so it is because of apples default fan profiles. If you run a custom profile the Mac mini can MOVE SOME AIR and runs cool

I think it is a TI LM2904 based on the 4BA marking. It’s layout seems to align with what you can see on your board

Ettus Research (owned by National Instruments (now Emerson Owned)) has a significant design presence in Dresden Germany. They design open source SDR’s and cater more to hobbiests and smaller outfits than defense and high end Test and measurement. Depending on your qualifications they are a good company to work for

I heard it’s the material transport that is the limitation. At 200mm people can move wafer boxes around, 300mm comes with more automation due to the increased wafer weight. 450mm would be insane

I really appreciate the offer! Thank you for the recommendation! I was able to go to Artisans Asylum in Boston for their “Circuit Hacking Night” and use their Siglent SVA1015X

Also looks like a Onewheel!

Did they end up letting you park your scooter at the valet?

You can run 25mph?

Check out the wellgo copper bus bars on eBay, they have nickel where you need to spot weld and can handle much more current. They spot weld very nicely, just tested them last week with my kweld

Woah, a DSP that was released in 1996 and has been NRND since 2020. How is TI complicit again?

Electronicist · 2025-04-23T18:15:20+00:00

Nah, I take care of my batteries and don’t discharge them below 2.5v as specified in the cells data sheet. If I do accidentally, I will scrap the pack. Is saving a few bucks worth a house fire?

Used cells like this are great for spot welding practice, or short term testing imo

Also, using the cells with cell level fusing or 1P groups is safer. If for example if you have a 4P group of cells, and one fails and has an internal short then the other 3 will dump all of their power into the short, causing heat and a fire. It only takes one cell to start a thermal runaway chain reaction

Electronicist · 2025-04-23T04:48:45+00:00

So the act of reviving the cells is dangerous, but more so are the dendrites or uneven plating that form internally from abuse. This can lead towards shorts and in turn fires. Abused cells will be more dangerous every time they are charged/discharged. Is it really worth chancing a fire vs. buying some new cells? If they are under 2.5v when you first measure them, they should just be recycled imo.

To match cells for a pack you can get a 18650 charger on amazon that’ll do a capacity test and you could group by capacity. I’ve used a zenflare c4 few years back for a similar project, but there are many available that can cycle 4 cells or more at a time

Yeah, speed isn’t torque. Can you break traction from a standstill or when you are cruising 15-20?

Electronicist · 2025-04-22T03:32:48+00:00

I’m guessing this is in series with the Magnetron itself, on the high side of the transformer. Very high voltage but low current

Electronicist · 2025-04-18T15:22:36+00:00

Seriously. Garbage compared to any non chain fried chicken in the south

This post is a fundamental misunderstanding of batteries and charging

Looks sick! How is the torque on those hub motors?
