     Good luck on yours, Poorness! Looking forward to seeing your video on it.

     Been looking forward to this since you mentioned it was coming a while back. Don't know how I missed it, but I did. Thank you, thank you, thank you for these. I have a pretty good understanding of this stuff now, thanks to you and a few others here. You rock, Brian!

    Heck yea! Post it here too? Happy building :)

    I got all the parts on hand... I'll be building one... video coming soon. :-)

    Got it. I think I was reading the negative (-) as a 1. Ha ha... but still... I didn't discern 1 and 8 are connected from the schematic. I totally see it now though. You're right about the numbers being close together. I am going to try this.

    1 connects to 8, as with most LM386 circuits, but only 2 & 4 go to ground, yes 3 is In & 5 is Out, only 6 goes to 9 Volts & yes 7 is not used? The numbers are a little close to each other in the schematic though?

    Right, they're connected to each other. I explained that weird. Sorry. Let me try again... on the schematic it looks like 1, 2, 4, & 8 all go to ground. 3 to audio in. 1 & 6 to 9V. 5 is the audio output path. 7 is open.

    However, the stripboard layout shows 1 and 8 connected together instead of to ground... unless I'm reading it wrong. Just clarifying which one is correct. Sorry for the weird explanation.

    In the schematic Pin 7 isn’t connected to the circuit, so it’s just hanging? Pins 1/8 are connected together through the uncut copper trace, but you can leave them open for more of a less distorted boost effect?

    Hey Brian. Looking a little deeper at this. On the schematic... the only open IC pin you show is pin 7. However on the stripboard layout it looks like 1, 7, and 8 are all open. Is that an oversight or am I reading it wrong?

    This is awesome BiranQ! Very detailed. I've not used a LM386 yet. I may need to try this.
