There was a forum crash today which seemed to have been caused by the attachments section of the SQL database. I was able to bring everything back but I have temporarily turned off attachments until I can investigate further. It should be back by tomorrow.

Open Discussion / Water Soluble solder in action
« on: January 21, 2020, 10:15:34 AM »
Finally gave this a try. I picked a white solder mask to test out and purposely grunged it up. Shows before and after with about 15 seconds of warm water and a soft toothbrush. Case closed - my new solder  :) I have some distilled water so I might try that out as well next time.

VFE Projects / Re: Bumblebee Q4 Emitter voltage
« on: January 21, 2020, 08:07:44 AM »
No worries. Okay, that's the base of Q4. So, R26 is connected between V+ and Q4 base which is what creates its bias voltage. A reading of 8v there means you might have actually put in something other than a 1M resistor.

If you look at the trace diagram in the doc you'll see the 1M just below the two .47uF caps that are next to Q4. Double check that resistance. If it is 1M we'll see what else might be happening.

Global Annoucements / Back in town

I spent the last several days in Urbana with my buddy Graham doing more pre-production for the next record. We had a great time and accomplished a lot. The groundwork for a good recording session has been laid! Also, their preferred sportsball team, the KC Chiefs, acquired more points in their competition against the Tennessee Titans, who are boring. They will go on to compete in the SuperSportsBall competition for the first time in 50 years and there was much rejoicing.

There are a few tech help threads and orders for me to catch up on which I will do today as well as start the BOTY voting. I should have a definitive update later this week on the new releases.

Lastly, I took a small pedalboard with an old version of the upcoming Mysterioso and the regular old Dreamtime. The Mysterioso slayed through his Carr Mercury. It is such a toneful overdrive with super smooth lead sounds. I think people are going to like it :)

Are you sure you don't have them labeled backwards? Q4 is the one on the lower half of the PCB and Q5 is at the top.

Then again, you shouldn't be reading 8v on either of those emitters!

FV-1 can't do -2 oct as far as I know. It does an okay -1oct but it gets pretty warbly.

It should say 2n3565. I will correct that typo. The link to the transistor on smallbear is correct.

These voltages look pretty good to me. There some variation but that's not unexpected.

What about your MN3101? Where did those come from?
Do you have a frequency measurement option on your multimeter? It might help if we can verify the range of you clock frequencies across the min and max delay times.

It's not that unusual to hear a bit of clock frequency in the BBD depending on where the clock trimmers are set, but given that there is no delay output at all the problem must reside in either the BBDs or the MN3101.

I was trying to guess what circuit it was based on this afternoon.  My first guess was a 5 knob small clone, but you're one chip short.  Not sure if I want you to tell us or wait for reveal.

Oh, it's no secret. I started with the basic Little Angel design and just piled on some stuff no one has done with it. The main added features are a width control (for adding throb to the LFO), an interesting feedback control (I forget where I pulled this from but maybe it was a flanger design), a blend control for dialing in chorus to vibrato and running the PT2399 at a slightly higher voltage. It all comes together and sounds pretty cool. You can get some really fun "steel drum" type sounds (or maybe weird plate reverb?) out of it at extreme settings. PT2399 chorus is not as lush sounding as a BBD based one but it's a righteous enough effect on its own. It would be interesting to port this design to a BBD version at some point.

General Questions / Re: Wavelord 1P8T from Smallbear NOT continuous
« on: January 11, 2020, 09:11:45 PM »
I should add a note in the build doc about the different switches. I don't want anyone putting artwork with the different waveforms only to have them not line up. In fact, I did this very thing when I first prototyped it (but because I wasn't paying attention)!

It is kinda strange that there are two versions of this rotary. Actually, I think I would prefer the version that stops anyway. I just have a lot of the other kind.

Oh, man. The Florist chorus is sounding like a whole lot of alright. I can't wait for you guys to hear it. I'm going to have to work on some new demo videos.

Audio/Video Demos / How to embed youTube in 2020
« on: January 10, 2020, 06:53:35 PM »
Upgrading the site to https has broken the old youTube plugin so I have installed a different one. It works nearly the same except for the following:
You need to specify a display width otherwise it will show up native which is like 1200px or wider.

To embed youTube do the following:


1) Click on the first icon in the highlighted area shown in the image below. This will produce the following code:
(youtube)(/youtube)
it'll be in hard brackets but I've changed it to show what the test is.

2) Paste the unique identifier of the video. For example, ***https://www.youtube.com/watch?v=dQw4w9WgXcQ is a popular video. dQw4w9WgXcQ is the unique identifier. So, our code would be:
(youtube)dQw4w9WgXcQ(/youtube)

3) Last, you need to specify the width of display. I recommend 640.
(youtube width=640)dQw4w9WgXcQ(/youtube)

Here's what that would look like as an embed:


PS If you rick roll I will instaban you for 5 minutes.

If you select the far right icon in the image below, you can display all the videos in a users channel. Example:



The new icons:

Got these from Amazon. Seem okay although I haven't used one yet. I prefer short toggles but these are good for prototypes, etc. $.60 each is quite right.

Here are some SPDT. Haven't bought these:

« on: January 10, 2020, 09:06:16 AM »
Okay, fixed. The https conversion broke the old plugin so I've installed a new one. The one caveat is you need to specify a width to keep it reasonably sized. I'll do a post that shows exactly how to use the new plugin.
