      his band in which he plays guitar would have seemed 100% normal in the eighties. I often wonder what his parents look like or listen to. maybe they listened to 60's music in the eighties and then he was born in the 90s, so there's like a lag. or it's a cyclical thing and all styles are bound to come back which is why I'm being subjected to the eighties for the second time (although this guy is totally amazing and funny). there are so many retro bands now. so you can imagine a musical universe that supports all periods simultaneously. but in just a few more decades, assuming one style per decade, it's pretty far out.

    • @LOOKMUMNOCOMPUTER
      @LOOKMUMNOCOMPUTER  6 лет назад +30

      yep like i said in the vid, i will be adding addons to this circuit, this is the core of the module, ill be including optional addons. square wave out + PWM in will be one of the add ons, only requiring another TL072, 10k resistor and a couple of jack sockets. i still need to finnesse, but you can definitely work it out if you look at the CEM3340 datasheet :)

    • @emilcarr7190
      @emilcarr7190 6 лет назад +9

      The add on is pretty simple, a comparator on the triangle out (saw might work too?) and the width is chosen by changing the voltage it's being compared to

    • @LOOKMUMNOCOMPUTER
      @LOOKMUMNOCOMPUTER  6 лет назад +13

      its even easier, check the CEM3340 datasheet, it already has square wave out, i just figured it would be a simple addone with 1 tl072 for input and output

    • @marizuokereke7347
      @marizuokereke7347 6 лет назад +5

      If we are planning to do the add-on's, would it be worth putting a tl074 in now instead of using two tl072's?

    • @LOOKMUMNOCOMPUTER
      @LOOKMUMNOCOMPUTER  6 лет назад +11

      yeah totally. would be an option later on. this just seemed easy for now, but yes. totally. when i do the square-wave one ill plop a tl074 stripboard layout in too

Always say "never", I'm not going modular, I just want an analogue mono synth with as low expense as possible.

    Man, now if you could get a MIDI to CV conversion going, and did everything else in this series, you'd easily have a homebuilt synth cheaper than the ones in stores cost

    If you want to tune this thing i less than 3min without any skill required and have a midi to CV interface and a computer, you can use my VCOTuner application here: github.com/TheSlowGrowth/VCOTuner
    It's basically a little game: Connect it up, then turn thr trimmer until the line of your computer screen is as flat as possible

    I've been waiting so long for a series like this. No knowledge on electronics whatsoever, but with videos like this I'm willing to try. Got yourself another patreon! What tier gets the additional information of the extra features?

    Great video. Like the rest of your video's. Is there a way to play the module using a regular midi synth? Would you be so kind to make a video creating midi to cv module? that would be awesome mate.

    bit of an update. my first attempt was thwarted by needing 072 op amps(of which i have none). i planned to use 2 741(of which i have plenty), but it seemed daft, so i ordered 072. postie just bought them so im off to try again........
