The skin depth, along with your knowledge of the dimensions of the part, will determine if it is possible to use the Impedance boundary condition or the Transition boundary condition. Lately I was wondering what other things are useful for building logic gates other than transistors.\nabla \times \left( \mu_r^īefore you even begin your modeling in COMSOL Multiphysics, you should compute or have some rough estimate of the skin depth of all of the materials you are modeling. OSaucey, or two 8 bit and addressing or some 4 bit What's pros of registers over shift registers?Īrchivist so, if I'm misuring 400V (3 digits on screen) with +-(1.2%+10), I get an error range of (-4.8-10=-14.8v) to (+4.8+10=+14.8V), am I right?Īrchivist: Are you talking about parallel input registers right? Wouldn't I need 16 pins on the MCU to write to it? Seems like a man was chopped to small pieces in the apartment im moving toīrick: i just need to add a linear reg and all should be fine Seems a shift register is the number suggested 74xx IC I see here. Password2, it works fine, and i trust my son to turn it the fuck up Is it some static fault the switches makes?īrick: and the volume control does not work don't want to hear th video games from other rooms of the house. Password2, the source is on circuitboards so i resisted post-amplifier, i know it's not the most elegant. Idk why tolerance for dmm works like that Thanks Triffid_Hunter what equation finds the dB? Well 10 of the smallest count on the screen I'm using it to control SS lines in an SPI system and they are active low Why do yuo want the IC to revert to high? Gotta do a full FMEA on the whole system too.Įven still (if its magnetic field power supply saturation) Yeah, they're not allowed to share power or signal lines per the rules (IE, particular power supply noise / the like) I'd suggest actually using two different kinds of potentiometers The rules? ah yes, for a throttle application that definitely makes sense If pedal travel/position differs by more than 10%, the car has to shut down. We have to use at least two encoders/potentiometers and compare them. Now i just have to figure out how to couple 2 of them to the same motion. Oh man I should have checked Octopart tooĪnd they're absolute. (not just chips, all kinds of parts too!) You can find some of those for about $23 USD Why don't they put that into monoprice HDMI cables Immune to external magnetic stray fields how Ya they got different types, linear and ring I am loading that webpage with "HALL" preset on my speakers It uses strange hall effect sensors and multipole magnet strips. So i made my own using some 3d printed parts and those hall effect doodads My complain with industrial rotaries is they were bloody expensive Very good for bulk cable (CAT6, HDMI, etc) a nintendo 3ds, probably cause of rough travel Trying to remember the last thing i owned that died under warranty. You get 2^14 pulses or ticks per 1/16 of the wheelįor every pole pair there is a resolution of 2^14, those encoder wheels have 16 pole pairsĪll of my monoprice stuff is failing these past 12 months I used them with a ring encoder for a resolution of 262,144 steps per rotation How does it know that 87% is actually 100%? :P Wetmelon: my car's TPS goes from 8% to 87% Some industrial automation stuff might have suitable sensors drive it like it's a chainsaw: wide open or idle. 20% tolerance, plus temp sensitive, plus wiring losses, plus. I have a dual potentiometer right now, but lots of variation in that. Isn't that 250 times worse than your last comment? Why does it need a throttle position sensor Inertial sensor for a throttle pedal also sounds like a oscillator waiting to happen It's not random, there are ways but not simple or generally applicable ones Yeah but they drift like a mofo, unless you buy a friggin' LRG Genewitch: but drift makes gyros pretty useless for encoder applications I was right! it was the diodes :3 the powersupply from abit ago Wouldn't you want the encoder to spin faster to have higher resolutionĪnd gears mean backlash, so it's not that simple Use gears to make a bigger diameter thingy spin slower, and have enough physical space for the encoder to read the edge of the bigger diamater thingy but I don't want to make a friggin' planetary for a throttle pedal lol Where do I find high quality, high resolution encoders? Like 400 + ppr, ruggedized (IP65+)
