[sdiy] Here's a link WAS: RE: Working PCB and module Tellun-867/OScope combo

[David Ingebretsen]

OK, so I have a preliminary link up. Just a couple of photos so far.

I'll add links to the project files soon.

Thanks to Scott Juskiw, Dave Brown, the guys at IBF who make Target 3000!,
PCB-Pool, and Schaffer.

Top label is Bulgarian and translates to OScope / A440 Hz
The bottom is DJB/Tellun in Cyrillic.

The scope is showing the A440 reference signal. You can't tell, especially
from the still but the LED's are showing a slowly rotating beat between two
VCO's which are very closely tuned. The left led is off, the top is dim, and
the right and bottom are bright.

Yes, if you look close, my soldering iron hit the input coupling switch,
sigh...

Not quite a Bill and Will or DJB project build page, but I'm working on it.
(My snack section will be a shot of a warm Mountain Dew bottle of dubious
age I'm afraid.)

Scott's documentation is great. I was very pleased and impressed.

There is also a shot of my Gabotronics scope module.

I highly recommend Gabriel's site:

www.gabotronics.com

I like the Gabotronics scope better, but I love the combonation module best,
I think.

Thanks everyone for the quick on and off list feedback.

I need to get my own web page working better anyway, I'll just bite the
bullet tomorrow and load them up there and will post a link. If the effort
utterly fails, I'll take someone's offer/suggestion and get them posted
somewhere else.

This is the Tellun-867 module. Dave Brown's A440 Hz reference, and a
headphone amp and beat indicator bundled with a "tiny scope" (see the
earlier thread) from:

I've got a FracRack .fpd file, as well as the PCB art with corrected silk
screen and will try to get my site functional and the images, 

It's my first PCB (in 30 years...) and I'm pretty pleased. Aside from a
couple of minor silk screen errors, it all seems to work great. Very cool
little module. Thank you Scott and Dave.

David

I believe posts with images get bounced.

I'm up for a bit, if you e-mail it to me I will post it to my webspace  
and post a link.
