In my search for different sequencers, Dave Brown pointed me to his CVS
project and a sequencer program he wrote.



http://modularsynthesis.com/cvs/cvs.htm



He provides the PCB Express file free to get boards made, but they are
pricey for very small quantities; about $258.00 for two boards with solder
mask and silk screen. About $99.00 for 2 boards without solder mask or silk
screen.



8 boards with solder mask and silk screen costs about $306, or about $38.00
a board.



If anyone is interested in Dave's project, I wouldn't mind coordinating a
buy. I'm not wanting to make money on the deal so I would just need cost of
the board, postage, the cost of an envelope/small box, and maybe 50 cents
extra for a soda :)



Let me know off list...

Julian, on the SDIY list, has offered to make panels as well. If you
hesitate because of no panel, you can contact me and I can put you in touch
with Julian.

If we can get a group buy going, I'll throw my hat in the ring for two. 

Scott Deyo (Bridechamber) has also talked about making panels for this project.

Hi David,

Yes, I do and I apologize for the delay.  I've been having a very hectic work week and have just been putting off making the payment.  I'll do it in a little bit. 

Cheers,
Eric

Only last night i was going through the pcb stack that i am yet to build and came to the CVS boards...

For myself, i am going to cut Dave's design -

http://www.modularsynthesis.com/cvs/DJB-CVS_front.jpg

I may possibly alter it to take the other type of panel mount DIN sockets, but i may just cut it as-is.

If anyone else is interested, i can cut them a panel too. Its of course easier if they are all the same, but it doesnt make a lot of difference, providing the metal needed isnt different for each one.

There's more details on the panel service here, if anyones interested -

http://www.thebeast.co.uk/cnc/

Thanks, Julian

Julian

I would be interested in the panel with either plug.

Using this file as a basis -


http://www.modularsynthesis.com/cvs/DJB-CVS_7-9-06.fpd



I have just priced up the panel, and it comes to GBP £58 (inc eu taxes, ex delivery)

This is about a 40% saving on shaeffers post-tax price.


These can be made in 1-off's (or more) whenever. I keep standard 5u format widths in stock all the time.

Julian

Julian

That is OK by me. When would you like payment.
I will be away all of September so if possible, delivery should be after that. I am in no rush for the panel at the moment. Let me know payment details as well. I am located

St Kilda 3182
Victoria
Australia

Hi Tibor,

Payment can be via bank transfer in sterling or euro (only realy any good for EU customers) or by google checkout (3.4/4.4% surcharge applies)


I could have a panel completed for you tommorow, however...

It might possibly be worth asking Dave for comment if he considers the panel design to be perfect, or if there have been any considerations that have cropped up in use?

Julian

Julian

I am happy with the original design. What is the final cost inc shipping to

14/1 St Kilda Rd
St Kilda 3182
Victoria
Australia

Do you accept paypal at all as this would be easier for me. If not, can I have your banking details.

Regards
Tibor

Hi Tibor,

So as to save the rest of the group, ill mail you the specifics privatly, although when the panel is done, ill post up a picture (or a link to a picture) of it here for the rest of the group to see.

Thank you,
Julian

>...when the panel is done, ill post up a picture (or a link to a picture) of it here for the rest of the group to see.

As promised, ive just finished Tibor's panel, and uploaded a photo here -

http://www.thebeast.co.uk/cnc/cvs.jpg

Thank you,
Julian

Nice panel work.

It looks like the panel is setup for the Ext I/O connector I chose which was a mini-Din. There isn't a lot of retention force to keep the plug inserted into the jack. There are threads on that jack so there must be a plug somewhere that will connect and screw in. I've been unable to find one. It works but could be better.

At the time I did my panel I chose Piher potentiometers because there were 16 on the panel and they were relatively inexpensive. They work fine but note if you use some other potentiometer the hole diameter is probably wrong. They use a 7 mm hole. Also note each shaft has to be cut off which is easy since they are plastic. I used RadioShack 274-415 since they were much less than the Tyco knobs.

I ended up masking and painting the edge around the LCD. It sure would be nice if someone could find a bezel that would work.

The biggest issue in building this panel is there is no PCB for the 11 LEDs. This is just waiting for someone to join in and lay one out and figure out a mounting scheme.

Nice to see some activity on this and hopefully there will be some more programs to share.

Assuming a threadded plug cant be found, may it be a good idea to swap the connector to somthing else - possibly even another D port?

This'ld be good for me, as milling the recessed plug, as specified in your .fpd file was tedious.

Changing the hole dia is no problem (if anyone else needs panels)

> I ended up masking and painting the edge around the LCD. It sure would be nice if someone could find a bezel that would work.

There is stuff used for engraving to colour very fine cuts black.
It works by oxidising and colouring freshly cut surfaces, so you can apply it to a natrural anodised panel, and itll only blacken the broken surface.

Anyhow, ive been considering getting some of this, but holding back, as its nasty carcenogenic stuff. If i do throw caution to the wind, it may be usefull for that kind of work.

> The biggest issue in building this panel is there is no PCB for the 11 LEDs. This is just waiting for someone to join in and lay one out and figure out a mounting scheme.

Even a pcb without mounting would help. The simple friction across 11 leds may be enough - but then again, this may be negated by the extra weight of the board hanging off the back?

I normally hate using adhesives as theyre generally no good, and, from a service perspective, are a very bad idea, however this may be an area where they are usefull?

Or possibly, two of the LCD mounting screws could be used on one side, and two more added on the other, to hold a LED pcb?


My machine can do pcbs also. Its no good for big runs, but for small quantities of simple boards, it may be worth considering.

That recessed connector would be a pain. I avoided DIN or D-Subs to keep other cables and plugs from accidentally being connected since there is power on that connector. I thought about using a 4 pin DIN like the Mouser 16HR654 connector. That size would be a little tight but would still fit in the layout.

The mini-Din isn't bad, there just isn't much retention force so you can accidentally knock the plug out of the connector. And ... they are very tiny to solder.
