    Speed control of this circuit

    I found this circuit on Pinterest, and most of those are usually inoperable, once made, so I would like to throw it at you more established players, and see what you think. As well if you think it works, can the speed control of the servo also be added to this?? Thanks in advance

    PERF BOARD!!

    Where can I get IC Pitch Perf Boards, PLAIN, no cladding, no Copper! Remember, Im I Canada, but I often order from the States, and Europe. Its getting progressively more difficult to find. Im an old fart, and I love this stuff to build on!!

    Servo Waving!!

    I dont mind using a relay to do the switching, just would prefer a non-contact sensing option, Thanks!

    Servo Waving!!

    Ok, I have a really basic Transistor Servo Circuit, to make the Servo move in a CW and CCW direction. https://www.pololu.com/blog/18/simple-hardware-approach-to-controlling-a-servo -I would really like a circuit that will sense the end stop of the CW direction, and then send the Servo in a CCW...

    Its actually the interfacing of the 4017, and the cd4010that is boggling me

    Pseudo randomness based on this

    2 questions -Is 2r and r the same across all the different op amps of the ics?, with the oscillation frequency controlled byt the various caps and resistors on the inputs? -Are these NPO capacitors or electrolytic??

    Quadcopter based on a smartphone motherboard

    there was already a drone that you slid a cellphone into. It didnt go any further than the prototype stage, as nobody was willing to slide their super expensive cellphone into, and have it fly off into the distance, when they could buy a drone, with the same capabilities, for about 50 bucks. I...

    while I have everyone's attention, can this TL071 be added to the out put of any basic Function Generator(2206, lm324, 8038), to vary the overall output??
