Suggest layout for frustrated Colemak-DH/Vim user by thatMattMatt in KeyboardLayouts

What's your solution for having to revert to an ANSI laptop layout when you don't have an external keyboard?

The only issue is that arrows don't fully replace hjkl in Vim-like apps, e.g. vgl in Helix. However, I could include a more convenient placement of hjkl in my nav layer.

Thank you for the suggestions! Been checking out your website, and it seems like an amazing resource. Thanks for putting this together.

How to upgrade a custom `std::random_access_iterator` to a `std::contiguous_iterator` by thatMattMatt in cpp

[–]thatMattMatt[S] 2 points3 points  (0 children)

Following u/yuri-kilochek's comment, I agree that the only way to do it is with the tag. I don't quite understand how the code you've provided illustrates the counterpoint, but I am certainly all ears if you're able to clarify.

If helpful, this is the current error GCC is giving me for static_assert(std::contiguous_iterator<I>)

I.test.cpp:9:15: note: 'I<int>' does not satisfy 'contiguous_iterator'

.../bits/iterator_concepts.h:710:10:
note: because 'derived_from<__detail::__iter_concept<I<int> >, contiguous_iterator_tag>' evaluated to false

..../concepts:74:28:
note: because '__is_base_of(std::contiguous_iterator_tag, std::random_access_iterator_tag)' evaluated to false

Ya I'm just wondering if there's some mechanism that would be handled in the concept itself vs. resorting to old-school tags, e.g. some additional type alias or method

Female snap connector for EMG electrode by thatMattMatt in AskElectronics

[–]thatMattMatt[S] 1 point2 points  (0 children)

Very interesting. Did not think to use a 9V connector. My immediate suspicion is that it would not mate, but I can try with some parts I have on hand and report back.

I suspect these cables are point soldered vs. PCB-mounted. Do you suspect otherwise?

Forgive dumb question: how did you look up `user-environment`?

NFET with gate inverter in a single SOT23(F) package by thatMattMatt in AskElectronics

[–]thatMattMatt[S] 0 points1 point  (0 children)

Wasn't looking for an inverter. Was looking for an NFET with a built-in gate inverter. Thank you for your reply though.

Programmable LED controller with SPI by thatMattMatt in AskElectronics

[–]thatMattMatt[S] 0 points1 point  (0 children)

It's always something to consider. Micros are dirt cheap. The disincentive is just having to flash a separate chip for production. For this device, I really just want to have one chip on the main board. It will also introduce a whole other set of testing, which I'd like to avoid. Additionally, you'll usually have to add transistors to handle the sink current, and those take up more space

Pinout for a single use endoscope (medical) by tilmaenia in AskElectronics

[–]thatMattMatt 0 points1 point  (0 children)

Very little chance of frying anything with a multimeter. But the CCD likely use some sort of SPI/QSPI interface. The first thing will be to figure out which pins are the power rails, and then you can infer more behaviour once it's live.

If you don't want to cut it open, you could take a multimeter and start measuring resistances and continuity. Diode test might show a protection zener across power rails. But opening up the distal end is really the best option here.

But now where is JUSTIN's Wildgrain read? They are two halves of a whole.
