Update in the bean household: my wife has been sent back to WFH for the next two weeks at minimum. They gave the option to employees to do this or stay in the office. Not sure what this means for the company's future. Also, some counties in Tenn. have decided to start the school year as online but they haven't made a decision in Sumner county yet.

So, everyone is back at home again for now. In unrelated news, I am available for adoption to a good home. Require minimal feeding and watering and only occasional bathroom breaks.

On the OG circuit, the delay pot goes to digital ground of the PT2399. This is supposed to be connected to analog ground of the PT2399 internally via a 10R resistor. But, often people run into it just not working that way. So, jumpering the two pins together usually fixes the problem.

Now, that may have nothing to do with your repeat problem. That could be a dodgy pot or something wrong in the circuitry of the feedback path such as a short to ground, bad solder joint etc.

As far as modulation the first suggestion may fix that. It's also possible to get a delay to modulate on its own by simply handling the circuit board, believe it or not. I've seen this a few times with analog delays. If you shake it around a bit the delay pot wiggles a bit and causes the repeats to change pitch slightly like you hear in modulation.

Okey doke, Tappy is out now. I believe I should be able to do a little video of the Tappy + Glasshole in action tomorrow.

Geez, I thought I had been building a lot lately then here's you, haha. These are great. And, that shucup is choice!

I was going to say that as well - no reason you couldn't ask someone to burn a v.2 for you since I don't think they are available for purchase any longer. I'd offer but I don't think I have the appropriate PIC in my supplies.

The diode pairs with the lowest forward voltage are the ones that get clipped. So, even with LEDs in parallel with 1n914 or BAT41, their influence on the actual clipping is negligible in those selections. It's just a bit or trickery to use an SPDT to get the three selections instead of something like an On/On/On DPDT.

VFE Projects / Re: Mini mu zener value
« on: July 06, 2020, 09:23:17 PM »
Did you mean 16v? That's the one most of them use. The VFE site has the power listed as 9-15v

The TC7662B has a maximum operational voltage of 15v. So, if you have a well regulated 15v supply and plan on using that then a 16v Zener is appropriate. If you only plan on ever using a 9v supply, then a 12v is sufficient enough.

I put an 18v on there before reading this. Will that work or do I need to go ahead and change it?

Using an 18v zener will not protect the chip against over-voltage should you plug in an 18v adapter. However, if you are generally careful and only ever use 9v then you probably do not need to replace it. It's just a question on how much you trust yourself :)

I will update the switching doc to include the correct zener value for the MiniMu.

Here's the Tappy with the optional faceplate. I have most of the documentation done so I do think it will be out tomorrow.

Forgot to add it. I'll do it in just a bit?. Thanks for the heads up.

Totally agree, I just trim mine up about every 6 months.
Before the pandemic, I used to get a haircut every 5-6 weeks.   ;D
Wow man. Thatís so often. I may have had mine trimmed 5 or six times in the last 5 years.

Not to play the 1-up game but I haven't had a haircut in 25 years probably. These days I just shave it all off every couple of months.
Back in the early 90's I had long curly locks and was a marginally handsome bastid. I've become peaceful with the ugliness of middle-age!

Not compatible at all, I'm afraid.

VFE Projects / Re: White Horse, IC1D pin assignment reversed?
« on: July 05, 2020, 07:14:57 PM »
Yeah, the right side of that diagram is wrong. The inverted input and output pins are always adjacent.

You are correct - the WhiteHorse inverts phase at its output. It's set up this way because of the way the Blend control is designed to mix the clean and compressed signals.

« on: July 05, 2020, 10:01:08 AM »
For whatever reason, some customers are still attempting to place international orders. Every time this happens, I eat the 3% Paypal transaction fee when I refund and cancel the order. So, I'm going to have to be a bit of a jerk from here on out and keep that 3% on any further instances. There is sufficient notice on the Store page saying international orders are suspended so it's hard to believe people aren't seeing it.
