Here's one of the things I've been working on lately - it's an Analog delay that I'm calling the R2Dlay. Started as a customer's custom order, now it's turning into a short run.
Pretty pleased with myself. Sounds glorious. Check it out.

(No, those aren't really MN3005's - they're Fakes that actually are MN3008s)

Very nice. I'm in.
Just finished building the Standard and Wazi boost, will try and post build reports this weekend as the wife has friends over so more time in the man cave.
That's a whole lotta chips. Impressive.
It says "may the force be with you!" That's all I needed to hear man, all I needed to hear!
What kind of delay time would we be looking at with four MN3008s? This just looks so sweet...
Woo! tasty! 8)

Same as 2 MN3005's. The whole idea behind this thing is for it to be like the DM-2/Aquaboy sort of sound, but double the delay time, and running at +15V not 9V.
Thanks guys.

Nice work Jacob!!
Looks great Jacob! ;)
I'm really interested in a MN3008 layout! Would you so a demo of this baby?
Reminds of a silly rap lyric I heard on the radio: "I should call my first child Bar... because I'm raising it"
Nice :D

I might do a quick iPhone one...

I would buy a board if one were available. hint hint.
What ever happened to this one Jacob? Did you get a chance to demo it?
Still working on it. I have a working board, and it's sounding pretty good. I have an enclosure and finally got my graphics printed up. It'll be posted soon.
I also found a guy with an O-Scope who will let me borrow, so I have to figure out how to bias using a scope.

Ah, nice! Looking forward to hearing it in action.

Drop me an e-mail if you need to :)
My goodness.
What I would *love* is to see a 4x BL3208 delay project (running at 9v, of course). It would be a Memory Toy Carbon Copy killer.
Nice work, bro. That's very impressive.
Maybe you could share the difference between an MN3008 and a BL3208? I think the filtering on this is adequate for the MN3008s, but I don't know if the BL3208's need to be treated differently.
Jacob
The Belling (BL) chips are the small 8-pin DIP package version of the MN3208. They are otherwise just like the MN version (same voltage requirements, etc). And they sound *way* better than the V3205.
So you can get decent delay time with a smaller footprint (and better tone to boot).
I think you could adapt your existing circuit the BL chips very easily. The pin connections are different, and you can drop the charge pump and all that. But the foundation of the circuit is there.
I'd buy several of those if they existed. I'm too damn lazy to draw up the circuit. ;D
I don't think Smallbear actually carry the 8-Pin DIP version of the 3208 anymore, which is annoying... probably would if asked though. They still have the 14-Pin DIP version though so you wouldn't even need to change the layout very much.
Yeah it's pretty simple to adapt the circuit, swap the power connections on the BBDs & Clock, adjust the compander resistors, done.
You could keep the charge pump if you really wanted for higher headroom filtering but it's not entirely necessary, people were happy with 9V DM-2s for years. Plus without that you have extra room for modulation if you wanted it.
Possibly add a shunt zener regulator, not sure if the 3208s react differently to 3205s regards S/N vs voltage etc. would need to check out the data sheet.
I think Mammoth has the small DIP. I can email Blake and ask.
You can also get the small version (BL3208A) on ebay for pretty cheap.
Cool, just expressing interest. So just out of curiosity, what would happen if I used 4 3005's (not that I have 4), would that increase the max delay time to 1.2s?
I love me some delay candy!!!!

It would, MN3101 isn't the best to drive that many BBDs but I think that'd be safe.
I've been a babbling moron just setting the trim on phasers, the MXR Flanger clone and the Electric Mistress. I'd need to be hospitalized after setting up that puppy! Nice work!
It's like getting your eyes examined with my phaser exploits. This one or this one? OK at fast speed: this one or this one. Now slow: this one or this one? AUGGHGHGHG!!!!!
Awesome work Jacob! I'd be in for a pcb if you do a run!

Totally with you on this. I've done with MN300n based delays. The ABDLX is my last (built, rocked, not boxed as yet). But I'll definitely do a BL3028 based one.

I was searching on BL3208 and came across this.. thought it looked interesting.. to say the least.

Looks like a "echo unit" for CB radios. lol
Dude! That layout is beastly. :o Nicely done...
