    need HP calculator

    I've got multiple calculator apps on my phone. And some on my computers. And physical calculators. Sometimes it's nice to not need to swap what's on screen, and instead just swap to a different device. Definitely worth having a good phone app or two (or eight, maybe I have too many) for...

    Minimum reliable SPI clock speed MPC3008 ADC

    That chip uses the SPI clock to generate the sample clock for the ADC. > The MCP3004/3008 A/D converters employ a conventional SAR architecture. With this architecture, a sample is acquired on an internal sample/hold capacitor for 1.5 clock cycles starting on the first rising edge of the serial...

    flame sensor

    Which flame sensor? Link the datasheet, there are too many different types with entirely different operating principles to know anything from just "flame sensor". Likewise for the solenoid. Do you have a circuit diagram? It's difficult to follow what's connected where from your description. The...

    need HP calculator

    There are lots of RPN calculator app or programs. RealCalc on Android, Orpie for Linux/MacOS/BSD CLI, or for a more full-featured GUI application Qalculate is extremely capable (even includes propagation of uncertainty & interval arithmetic).

    New AI Program available

    It's an interesting one. The architecture is also open, this article is a good introduction to it (though it requires knowledge of how other LLM concepts like transformers work, the same author has similar articles on many of those).

    California Dreaming No More

    The area that burned this year hasn't burned in the last few years, so it's hardly "an area that's been burning nearly every year". Unless you mean the entire state of California! Eucalyptus trees are part of the issue. They were imported for several reasons, and invasively spread across...

    allowed file extensions for attachments

    Since .zip is allowed, everything is allowed. Even if it weren't, you can always change file extensions to an allowed value & note what to change them back to in the post (though this is annoying, it proves the futility of allowing only selected file extensions)! As proof, I've attached a random...

    Entering a non-breaking space into a post

    Compose space space is the default sequence for a non-breaking space on MacOS and most Linux distributions. Be sure your compose key is enabled, not all OSes turn that on by default (Windows requires the third-party WinCompose to even use a compose key in the first place).

    subscripts/superscripts

    One types them, using the keyboard and your OS's input method for doing so. E.g. for me on Linux that's a Compose key (where right-control would be), so to type x² I type the sequence x, compose, ^, 2. Windows users are stuck holding alt & memorizing numpad codes, or installing third-party...

    Non-breaking spaces and hyphens

    Type one. I don't what your OS/system is set up for, but for me (NixOS defaults or Windows with WinCompose) it's Compose Space Space for non-breaking space. Not sure what you mean by a non-breaking hyphen. That's not a standard character name in Unicode. Also this is the programming language...

    Wrong subforum. This one is for discussions of the eng-tips.com forum itself.

    How Should I Help My Cousin Succeed With His Ambitious Engineering Project Without Taking Over? (PhD supervisors please pitch in)

    Leading questions are great. If you think something is wrong, ask them to justify why it's correct. Beginners don't know what they don't know, so making them justify the choices involving those unknowns will help them come to their own conclusions while also forcing them to learn about the...

    Spell checker

    Interesting, I only see my browser's default behavior. There is a spell checker plugin for the editor they used, but I don't see any references to it in the JS when searching in the debug console (F12). And I don't have the svc.webspellchecker.net domain blocked.

    subscripts/superscripts

    I don't see an option for it. For some characters there are unicode options: all numerals, plus, minus, parentheses, and some letters: ⁰¹²³⁴⁵⁶⁷⁸⁹⁺⁻⁽⁾ⁿ ₀₁₂₃₄₅₆₇₈₉ₐₑₔₕᵢⱼₖₗₘₙₒₚᵣₛₜᵤᵥₓ We can also just type out LaTeX in code blocks. $\int_{a}^{b}f^{\prime}(x)dx=f(b)-f(a)$ It'd be much nicer if the...
