One of the downsides of a delay based vibrato is a tiny lag. Like a 15th/20th of a second. It doesn't really bother me, but it might bother some.

I couldn't get the depth I wanted with a lagless phase shift circuit. Especially at the slower end.

Just a couple of transistors. I based that section of the uC->delay chip modulation from this:

The couple of transistors and passives did fine. (with a few tweaks)

That's really cool, I'll have to look more closely at it when I get home.

Either that's pretty amazing, great work!

Man, that last page was great. Especially Laowiz and cloudscapes!

That vibrato sounds amazing. Like just musical and weird enough.

My latest is a pretty straight-forward V3 OCD clone on vero. I couldn't easily source 16mm 500k pots here, so both the gain and volume knobs are only 100k. This actually makes the range on the knobs much more usable in my opinion. Getting the right volume level on my real OCD was always a bit touchy, and I never had the gain cranked way up anyways. That said, I feel like 250k for gain would have been ideal, but that another value that's harder to get in 16mm here...

I finally fucking did it. I've successfully soldered and programmed a STM32. I was rewarded with a fully working Braids!!!!!

what? just tqfp 48? pshhhhhhh.




goood job

Is that for the Zellersasn? I saw the 4MS Spectral Multiband Resonator uses those honking big ARM chips, but I actually have a method now for doing these things that seems to be foolproof for me so I can do it all now!

No more complaining about TSSOP packages for me

oh that's great.

ya it is for 856 and beyond hopefully.

nice work on the tiny passives

Thanks!

They're really easy to do with the tackdown method. Out of curiosity, how do you solder on the ARM processor?

What works best for me is to liquid flux the board, place the chip, and then put a dab of solder on the tip of my iron and tack down from left to right. Like:

1 2 3 4

basically i try to line it up on the pads using a microscope. then i do one corner and then align again. then do a second pin in the opposite corner. make sure it is aligned. after that it is pretty easy, i do what i think you are saying after that. if there are bridges i just use solder braid to remove the bridge.

so its more liek pin 1, pin (Number of pins)/2 , pin 3, 4, 5 etc

the bigger ones are a hassle because i dont have a tool that can hold it like tweezers that big etc and i drink way too much coffee.

I admire your courage in routing a billion address traces to that RAM

Yea that's how I start it out. Then I just do pin 1, and then pull it out, go to pin 2, etc. It's a very smooth motion once I get in a rhythm. Visually, it would look like a hill I guess? I do need to look into a better microscope to line these pins up. For now I just use a magnification headset that does the trick but can get a little hairy.

I just do this on my own time so I'm drinking beer instead of coffee .

ya nice.

i have a binocular microscope that i used for the last several years and it is pretty good, but my neck gets sore from using it for long periods so i recently bought a (cheaper) digital microscope and just plug it into big monitor. Visually it is not as nice as the real microscope, the colors are a bit shite and there is no depth perception but you can just sit back, its easier on the posture. and it takes up less desk space so that is nice too.ill try to post a picture later.

yes next board = bga ram though. no more pussying about. >:|

Just got this Meatball style enclosure in the mail. It's a beauty and now need to figure out a good solution for etching steel. Also need to figure what I'm going to put in it!

I have been using gun stock dye on steal. Mask, then dye, then acetone. It is not etched, but looks cool and if you use a sponge you can make it look gnarly

This enclosure was done with dye:
