I remember being a child and building a space station (it looked a bit like StarLab so I guess the station in general was on TV or in a book) with a solar array that shape, my parents were a little angry and asked where that shape came from. I didn’t have a clue so I basically just said I liked the symmetry. They told me that’s a "very bad shape and that I have to rebuild it. It ended up being 8-shaped, which was also nice.

I was feeling the same :D.

Boy, because of 500c you made me do all that? I was feeling like the Crimson Fleet treated me nicer here.

Maybe this: https://www.microchip.com/en-us/product/PCI11400 Unfortunately to access the whole datasheet you might have to sign an NDA (and probably have a large company), also designing things with those kinds of interfaces isn’t trivial.

Alternatively maybe this: https://www.renesas.com/us/en/products/interface/usb-switches-hubs/upd720202-usb-30-host-controller It also seems to be locked by an NDA.

They are called soft termination, I’m not sure if that’s available for every component, it came to my attention on ceramic caps. It’s a dedicated feature you can filter components e.g. on Digikey.

I’d say that’s a version of a soft termination capacitor. They are used when there’s risk the board is flexed or exposed to mechanical or thermal shocks to prevent cracks in the capacitor (causing it to fail short).

Not sure if that helps your research. We have an (very expensive "upper 4 digit region" they didn’t tell me exactly) DJI drone (an Matrice 30T if I remember correctly) at work that has the option of operating autonomously with a base-station where it also automatically lands and recharges. The catch is it’s like impossible to operate autonomous UAVs here because of airspace restrictions (that’s why we only have the "manual" version without that base-station thingy). I’m not directly involved in the department that operates the drone so I don’t have more in depth insights but maybe that already helps a little.

Fun fact, our military had to cancel a large and very expensive drone program because the drone (a little larger one tho) couldn’t get certified in European airspace ("Eurohawk" if you want to google that). So I’m not sure how easy it will be to hack something together depending where you are in the world and what restrictions say there.

Mine is the smallest one of a series of these, it has two heating elements inside.

I don’t have it for that long but I didn’t have problems so far, I’m usually only making rather small PCBs tho. I did make some recommended modifications like replacing the paper insulation tape with a kapton tape, proper grounding and flashed another firmware.

I did only use a small hotplate and/or a hotair station, so it seems to be definitely a stepup here 😌.

Maybe you can use this to find more connectors that could match yours: https://connectorbook.com/identification.html?m=NT&n=lo_prof_1r_w2b_conn_1p2 It has a pretty handy identification tool (you can even browse by pictures). It usually suggests quite an amount of connectors but it can guide you in the right direction and you can look at the according datasheets to find out more. By the way the creator of this community made that homepage and a book related to it (or probably the other way round 😅).

I’m currently working on a more complex project that uses double sided assembly (and a weird USB-C connector). To practice these things a little, I ordered some low cost boards to get used to that connector and explore double sided reflow (which seems easier than I expected).

For those who are interested, this is a reference design from framework computer for their expansion card system. It can be programmed with circuitpython or Arduino and utilises a SAMD21 microcontroller.

Oh don’t be afraid it doesn’t go to nowhere :D. I just posted some images how that line continues :).

The train on the left is heading into an (under construction) underground section

There are also some leftovers from a crashed monorail train (no monorails were harmed here, it’s built from regular parts).

On the other end the trains are heading into (modified) winter-village.

In between there are some areas that aren’t built yet but there’s quite some space left. Also I’m a little surprised that shelves hold it up that well :D (they are bolted to a substantial brick wall tho).

I created a little shelf-city over time that is connected with a monorail line.

Say hello to Trixie :). She’s around eight years old and got here as a young kitten after being left in a cardboard box on the side of the road and my ex-girlfriend brought her here. Girlfriend of that time left, Trixie stayed and lives here since then.
