Magnavibe PCB (Gauging Interest)

[raulduke]

Hi Guys,

My last batch of PCB designs that I had fabbed included a Magnavibe clone.

This circuit sounds fantastic; its like a subtle, swampy, vibrato tone.

I was wondering if anyone would be interested in one if I ordered a batch?

I would also do a BOM/Build doc. for the PCB's.

I'll be able to give firm pricing later but I imagine it should work out to around £5-7.

The only slightly tricky bit of the build is getting a good LED and LDR combo.

I'll upload some photos of my build (and the PCB) later.

Let me know if you are interested.

Cheers.

I'd be interested in couple - I've built one on vero for myself, and it got "borrowed" by my mate for his rhodes, and never came back

I'd be interested in this, and I trust you have some tips on the choice of LED/LDR?

Yeah sure thing.

I used a superbright blue LED in mine along with this LDR: http://cpc.farnell.com/jsp/search/productdetail.jsp?SKU=RE05271

The FSB thread has also got some useful info on it:

The LED/LDR combo is not mission critical; it will work with pretty much any LED and LDR, its just some tweaking may be required to get maximum 'wobble'

This does sound cool. Any idea what the bottom line would be for us in the U.S. shipped?

Also, do you know the dimensions (width mainly) on the board? The second picture looks a little funny.

Sounds cool, I'd be in too

Good Stuff.

The bottom line I will try and get to will be around £8 (shipped) hopefully. Hopefully I could get it down less.

The PCB measures 1.9" x 1.25" and is designed for PCB mounted pots. Will easily fit in a 1590B.

I used normal pots in the build shown, and stuck the PCB down with twinstick; hence why its not centred.

I think I can get it into in a 1590A. Ergo, I'm in.

+1 for intersted!

[sgmezei]

I am in!

[raulduke]

Ok, some guys on BYOC are in as well.

I'll tot up numbers but I think the order will be around 25 PCB's.

I'll put the order in ASAP.

Cheers Guys!

If the order isn't placed, I'm in for 1.
