    Need some help finding direction for a new project

    Yes, acconeer will likely do it. They also offer lenses, which will change field of view & range: as field of view narrows, range increases, as more power into smaller beam. They need programming and the result is as data of course, you still need to get the answer out somehow, eg a controller...

    Large Currents vs Small Currents

    Maybe work backwards. Look up the ones of interest. Note the currents they list as absolute maximum and whether the description is "high current" or not.

    Need some help finding direction for a new project

    If the bin is narrow, includes vibration, or otherwise self-levels the top of the feed, then measuring to any point on the surface will give an estimate. Standard level sensor in air, often for water are ultrasonic and radar. If your level is distinct, a standard laser distance measurement...

    Need some help finding direction for a new project

    A simple mechanical solution seems a really good option. . An alternative way would be maybe a level sensor, either permanantly mounted on the top, pointing downward, or on a selfie-stick. There are lots of level-sensors for water & similar. Depending on your feed and geometry, such a sensor...

    Large Currents vs Small Currents

    It depends on the context. . For one cracker, three slices of cheese is a lot. If I sell cheese professionally, wholesale, 50kg is a smal amount of cheese. . With some degrees, there is a distinction high current = power electronics or power engineering/distribution, and low current = analog...

    BJT vs MOSFET for logic gates help

    Interestingly, https://en.wikipedia.org/wiki/MOSFET#Circuit_symbols shows Which seems to talley with what Harald Kapp was saying.

    Looking for Collaborators!

    As varied as mechanical engineering is, so are specialisations in electrical/electronics. Might want to specify what sort of skills you are looking for, . For example; sensors IOT, communications/wireless, cloud services Machine vision Multi-spectral or hyper spectral AI Power electronics...

    BJT vs MOSFET for logic gates help

    Go for it. The megaprocessor has quite a number of registers when you get down to it. Might want to read up on "RISC" designs to get an idea of how small you can go. . Why 8-bit? Have used 4-bit processors in the past. Can be just as much fun. . BTW: Instruction set width does not have to match...

    Help to identify IC

    https://www.worldwayelec.com/search?k=CN19076N lists it, seemingly without information. http://www.chesscomputeruk.com/html/fidelity_spare_parts.html Lists it in on a page called "Fidelity Spare Parts" in a table called introduced by These spare parts were purchased from Peter Roberts, who...

    BJT vs MOSFET for logic gates help

    I've seen three conventions. Electronics (Most ocmmon): Power, often positive, at the top, ground, or negative at the bottom. A sense of up is higher potential. Signal flow, usually left to right. Physics texts: Power supply potential is left to right, (Battery at the top) Signal flow, well...

    BJT vs MOSFET for logic gates help

    Like you said, each input is connected to high or low, never floating. You can arrange this any way that suits. . Normally it would be driven from some other output, such as an oscillator or similar. Another example would be a digital output sensor. Internal circuitry derives a digital...

    BJT vs MOSFET for logic gates help

    I'm not sure that we are all on the same page. I, at least, am having some trouble working out what's intended. . Certainly didn't follow ratstar's explanation, sorry. . On your diagram when the switch is open there is no bias on the gate. So, the gate capacitance is charged when the switch is...

    Gpu and high power requirements.

    I'm not sure what you're looking for, but if there are capacitances, even stray ones, to be charged and discarged, then the faster you go, the more energy you'll need. . You seem to be considering massively parallel: Have you looked into quantum computing?

    voltage divider with load question and guess

    Seems that a pipelined FPGA might also get the performance you seek. :)

    voltage divider with load question and guess

    Perseverence is good. :) . I'm intrigued with the analgoue computer concept/aim/goal. . When people say analogue and digital, or even analog and digital, they usually mean something like digital: discrete time, (sampled) and discrete values (quantised, and represented as bits) analogue...

    voltage divider with load question and guess

    Seems he might have been a little hit and miss with the design in this example and experiments as variations from it. Not sure further anaylsis of this one will help him. . Seems as if he is striving for something that is not yet present in the circuit.

    voltage divider with load question and guess

    Sure, you can make an oscillator with a storage capacitor and something that conducts when it hits a voltage threshold and stays conducting, for example till the current drops below a threshold. (so it resets to charge again) It's that second bit that makes for the oscillation rather than just...

    voltage divider with load question and guess

    So, I came into this one late, just checking; It's DC, right? What colour is the LED? This changes the voltage across it. The LED and resistors conduct current, so they fix the voltages at different places in the circuit. After any initial transient, the capacitor charges up to a voltage...

    voltage divider with load question and guess

    Have you tried circuit simulators? There are a range of simulators based on SPICE that tend to work well, in both transient and DC analysis. Generally if you can't be bothered doing the study to solve circuits, these will give you an answer very close to what you'd expect to happen. I think if...
