    I want to know all of the maths concerning this scissor mechanism!

    so I've been through the maths and it doesn't work out the way I wanted - but not going to give up! I'm going to build it and see if it might work how I imagined!

    cheap cnc milling machine not controlled by computer

    saw this wanted something like it but a bit more sturdy

    cheap cnc milling machine not controlled by computer

    Hi guys it's me birthday :) anyone know of a cheapish cnc miller that can be controlled by a keypad or buttons rather than a computer, for metal? thanks

    possible to make hackrf like device with esp32 arduino??

    nice suggestion Mr Bertus!

    possible to make hackrf like device with esp32 arduino??

    to start with it would be nice to tune into am fm and longwave radio and the to hear walkies taxis stuff like that

    Where to start/post project to do with my grandson

    get solder with rosin flux core aswell makes life easier to solder!

    possible to make hackrf like device with esp32 arduino??

    ok well I won't start this one till I've finished the light board! your comment of not finnishing projects has spurred me on! I'll get it done soon!

    possible to make hackrf like device with esp32 arduino??

    I'm going to finish the light board - and it sounds like this one can't be a project because of the word "hack"!. Starting back up on the wheel project got another wheel (heavier) and stuck the magnets and bought a kilo of square structural parts for stability (lego technics) strarting that one...

    possible to make hackrf like device with esp32 arduino??

    Hello people is it possible to create something similar to hackrf protopack 2 with and arduino esp32 I already have a few and also have this screen...

    I want to know all of the maths concerning this scissor mechanism!

    so I've had a radical idea does anyone know of a mechanism the keeps the flat part flat as the lever rotates clockwise around the circle (pivot)if you can't understand the drawing just ask my idea is to have a shiftable weight that sits on the flat part and when lifting up the weight would be...

    going to work through it again

    I want to know all of the maths concerning this scissor mechanism!

    I want to relate this 0.15m/s to the rad/s of the cam! I think it's just pi rad/s sorry for the stupidity I don't know what I was thinking 1 revolution in 2 seconds!

    I want to know all of the maths concerning this scissor mechanism!

    look at this site https://www.omnicalculator.com/physics/gear-ratio and scroll down to input speed this will be 2pi from the flywheel output speed is where the cam speed should go the output torque is what will be Fh * smaller radius of the cam then it will give the required torque from the...

    I want to know all of the maths concerning this scissor mechanism!

    the equal and opposite force of 11.3097N keeps it still or at a constant speed so this tells me that the cam has to be moving at a constant speed how do I work it out?? thanks this force at the cam is Hf = 1.6964N

    I want to know all of the maths concerning this scissor mechanism!

    v = (0.95 * 0.3) / (0.95 * 2) = 0.15m/s a = v / (0.05 * 2) = 1.5m/s^2 add up accelerations 9.80665m/s^2 + 1.5m/s^2 = 11.30665m/^2 F = ma 1.1528kg * 11.30665m/s^2 = F of 13.0343N to accelerate in the 5% of the 2 secs and for the remainder of the time 11.3097N so the accelerating force at the...

    I want to know all of the maths concerning this scissor mechanism!

    do I accelerate the weight above the scissor and relay it back through the scissor to Fh
