Honestly, at 66, that sounds like a dream come true.

Last post by peAk - Today at 02:40:16 AMI am not sure what circuit streams you are talking about but I did just watch that Beach Boys thingie. It was cool but mostly because of Chris Cron.
Nothing against Josh or Rhett, but Chris stole the show by far.

Build Reports / Re: Baron of Arizona flanger #...
Last post by blackhatboojum - May 17, 2024, 02:39:14 PMI recently revisited this build, and played around with different voltage regulators. Here are the results in case anyone might be interested.
Pedal at 12v with a 9v regulator: Brian mentions in the build docs that this configuration can be used but, hasn't been tested. I've now tested it and I can say... it doesn't work. It ticks, more accurately, thumps like crazy.
Pedal at 12v with a 6v regulator:
Works, doesn't tick, but results are not desirable. There is a significant increase in volume when engaged. This is to be expected since the op amps are getting more voltage but, the bbd is not receiving a voltage benefit in terms of headroom. It's still being regulated to only 6 volts. The extra volt also changes the clock speed quite dramatically. Stock voltages gives me speeds of 40kHz to 530kHz with a sweep of the manual knob. The extra volt causes the speed to jump up to 830mHz with the manual knob maxed. At that speed, it sounds really warbly and off putting to my ears. It's no longer a flanger and more of a seasick chorus sound.
Pedal 9v with a 6v regulator:
Very similar to being run at 12v but, without the volume boost. Again, not very desirable to me. That boost in clock speed just doesn't work for this circuit. There's probably a resistor in the clock network that could be changed out to bring the speed down to a more suitable range but, I don't see the point. That extra volt doesn't really help the bbd in terms of headroom from what I can tell so why bother. 9v with a 5v regulator seems to be the sweet spot for this circuit.

Last post by Pish - May 17, 2024, 07:26:42 AMAm I right in saying that the inverse here is same as reverse?
So not much change between no feedback (at full resistance) and 2 but better smoother control for the rest of the range?

General Questions / Re: Soldering iron suggestions...
Last post by jwin615 - May 17, 2024, 02:13:59 AMHad a aoyue 936(the older, bigger one) for 15ish years. It has no bells and whistles but works fine. Takes 90-120 seconds to get to full heat but maintains really well.
Auto off is a good function to have though and would recommend it in any new purchase scenario. I like the S7 tip. Only use genuine Hakko tips. Never had a knockoff T18 that was half the weight of a Hakko.

Last post by jimilee - May 17, 2024, 01:06:02 AMSounds like a part was subbed, BUT the C10 will give you a little more control than the A10.
