I agree! And especially when its fairly simple to build well, and important in operation, you would think the average quality would be better. My car stereo will often turn up the volume when I'm turning it down, I want to try fixing it with my next design and video

Even Ford car radio had these problems.

There is a part 2 if you want to get geeky on it :)

That's the reason I post, in hopes to inspire. Feel free to reach out if you have questions/troubleshooting the circuit :)

I'm working on my transcript for that exact video! Only 5 transistors, some diodes and resistors.

@@arenotdiy7280 sounds like a miracle to me 😀I am eagerly waiting for its final form. thank you so much for your efforts 🤙

Perhaps! Its always a juggle with ease of design and component coservation. I think simplicity and elegance should be the goal. I plan do go into depth in my next video on the 5 transistor version I mentioned that yeilds the same result, with maybe more accuracy and certainly less current use. I'd love to hear any results your experiments yield!

The 1M resistors are there to limit the current the BJT inverters are always sinking, as long as the encoder isn't being turned. I didn't like the idea of its quiescent current being higher than it needed to, and 1M resistors still let the cmos D-flip flop operate. I have another video planed where I explain the 5 transistor solution, as well as build a "one knob" video game remenicent of space invaders, with just logic and LEDs. Thanks for watching!

I like the idea, it fits my penny-pinching attitude! I think I had better luck with my debounce circuit this way, I'll need to give it a test sometime. Thanks for watching!

Its always special getting to spend time with birds. I started wondering if the CZcams algorithm shuffled this to the bottom of the stack, because cats are not to be demonized (per all the views they get) lol. Thank you for your kind words :)

Haha, those are the hinges, I made them out of some aluminum. That's all I'm going to see now when I look at them

You are totally right! It would be a problem if the encoder was left inbetween indentations long enough that stray voltage could build up on the set pin. It would leave both set and reset high, giving a rising edge on the "clock" output, even though the encoder hadn't been turned. The same goes for the clock pin of the "up/down" flip flop, it should be pulled low with a 1M resistor in theory, because to my knowledge, the 4013 doesn't have an internal pull down resistor. I didn't experience those issues with my experiments however, and with me being the fraction of a penny pincher that I am, and also wanting to simplify the concept as much as possible for its presentation, I chose to omit them. Thanks for watching and pointing that out!

I believe in you! I plan on having DIY kits available for all my projects, this one included. The pcb protoyping is taking longer than I would like, but the first wave should come before the end of the year!

I feel it.. I would really like to do a comprehensive Do It Yourself circuit bending video. Because its all about just making what you have on hand work, which is easier shown than said :) THAT being said, I just popped the backs off of battery powered toys with speakers, found the microchip clock resistor, swapped both with pots, (for pitch bends), passively mixed them, sent it through a pt2399, and powered the blue speaker with a class D amp, pam8403 I think? The solar panels put out 6 volts max, and charge through a tp4056 lithium ion battery charger/discharger, to a 18650 cell. The whole system runs at battery voltage, no step up.

Good day sir, I have a video with a schematic in the discription for the x4 looper I made, czcams.com/video/q-XtoXvElmY/video.html And here is the datasheet for that ic (I know it says 1800, but its the right one) www.google.com/url?sa=t&source=web&rct=j&url=www.nuvoton.com/resource-files/EN_ISD1800_Datasheet_Rev_1.0.pdf&ved=2ahUKEwiE96Cj4sz-AhVqOEQIHTxsDCEQFnoECBoQAQ&usg=AOvVaw3KAG6c4jsjstkMpw0zfmzI Good luck!

Well, it does leak a little when an oscillator turns on, but several well sized caps right next to the 40106 helps keep it out of the audio path, and the important part is the oscillation it actually terminatend in the feedback loop of the Schmitt trigger with the 6 on off buttons.

@@arenotdiy7280 thanx for your quick answer, I will try some different values of caps on my next attempt, hopefully to get hardsync and saw waves with diode in the feedback path working smoother too

Good fun and luck!

Sorry you didn't like it friend :)

@@arenotdiy7280 I wanted to, because I love circuit bending, but I get motion sick ☹️

Good day, I send you a comment on your recent video: czcams.com/video/VPK145Qxuv0/video.html

The top three are noise generators of different style controls, but all based on 40106 ic square waves, and mixing them with a logic gate XOR 4070 to get the metalic harmonics. The bass drum is just a twin-t filter made with lm358 op-amps. Each voice has a resonant filter, although I think that was a little over-kill :)

I might try and make more of these as DIY kits with PCBs, we'll see

@@arenotdiy7280 Yes! DIY kit please!!!!

It's a super basic set-up, the speed/pitch knob is only 20k I think, which may be causing that effect

Do it!!!

Yes :) I'm putting together some PCB's right now for DIY kits, and a X4 Looper is one. My plan is to have them all compatible for custom builds. Thanks for watching!

@@arenotdiy7280 I put in a reset feature to be able to reset the loop among other things for the ISd1820 in a schematic. It's free to use for your project if you're interested.

Should be coming soon. It will be a very broken down series explaining the oscillators to the filter (and some extras!) In great detail, from circuit analysis, to breadboard, to protoboard. I might even make some pcbs

Thank you YT insomnia algo

Thank you! I think I had those knobs from a large Amazon purchase? They're glossy, and have silvering, but They're so small they wouldn't cover the nut on a regular potentiometer. They work great for smd pots though!

Thanks! Keep it up, you'll get there!
