Looking forward to the QFG boards, as well the others that will hopefully follow. I could gauge from the amount of info that Randal heaped on me along with answers to my simple questions, that he was SUPER ambitious; overflowing with ideas and enthusiasm. It would be lovely to see some more folks willing to shell out to supply us all with quality boards of great designs we may not otherwise have access to.
I really hope that the lovely EM that I have come to depend on in the last year or so can maintain the cooperative spirit which so many of us enjoy. Bill was well within bounds to ask for a formal declaration of what is up with the boards, Randal has offered up plenty of info in return. Lots of snark can be implied or imagined in our flat impersonal type, very rarely is it worth getting too bent out of shape about. I will live another week without my boards, two im not sure....

Having read Randal's explanation, I too feel the need to clarify.
My main complaint in this entire thread was that of communication.
When the call for pre-orders came out i responded to Randal in a PM. I had not seen his munged email address and wanted to be included in the pre-order list. He responded to me in a PM as well, and indicated that he would let me know when the actual ordering and payment could be done.
I waited....and did not hear anything...waited...etc.
Finally when Bill spoke up about the lack of communication to customers, I stepped up my communication to Randal via his email address.
I felt left out in the cold, and uninformed. I believe that Bill's intent was spot on. We needed to hear more from the vendor. I was not so much concerned that there would be a wait for the board(s). I was concerned about the seeming lack of communication. I did order a board from Randal very recently, which shows faith in his ability to deliver.
I believe that this is an opportunity for many of us to learn how to improve the process. I made a mistake in communication, as did Randal. Lets learn from this, improve our ways and go on to better and more musical things.
I look forward to receiving my board, and building another of Thomas' wonders. |

They're here! In fine geen and gold plated RoHs form...
Electroless nickel gold plating on all pads. 2-1/2 oz. copper. RoHs rated substrate.
See pics of the THD107A board front and rear on the first page of this thread. (up now.)
Pots shown here are: Alpha, Bourns, bourns/Omeg, and panasonic/alps
Or You can use a 3pin .100 header instead at each pot location.
trimpots can be inline or "triangle" style.
The row of large holes allows BIG capacitors to fit for really slow cycling.
Or smaller ones. Or two in series. etc. There are three timing capacitor locations to be used with an SPDT switch, which has a 3Pin header location on the board. (Just to the left of the large row of pads.)
More later. I'm glad they're here. I do have some extra's
Thank you all for your patience and kindness.
Randal

Thank you Scott! As for heavy, this one wasn't too bad The next box will be the heavy one! But Yes, this one carried all the weight, so to speak! P.S. Keep an eye on your mailbox.
mono-poly wrote: | Great news Randaleem! Did you get any other boards to? |
Thank you Mono! No, just the QFG's in this shipment. As previously mentioned, the plan was/is to have the add-ons two weeks after these. I will be seeking orders until Wed. for the PWMx4 and 2164 quad VCA PCB's which have been designed to work with this module. (I'll post more about them in a new DIY thread soon.)
Then on Wednesday I will tell the board house which already has the excellon and gerber files (AND a CLEAR understanding of the timeframe!) how many to build. These will arrive two weeks or less from Wednesday. So I'm promising them by the end of this month. And this time they WILL be here by then. (excl. Acts of God, war, etc, blahblah blah)
EdisonRex wrote: | Hooray! They certainly look great! |
Thank you EdisonRex! It's been a long time coming. Still quite a bit to do!
Thank you all again for your patience, understanding and words of support during these last several weeks!
BTW, I'm working to have panels available for the QFG's if there is interest at a 15-25USD price range for Euro to Frac to MOTM to Dotcom (from least to most expensive in that order. Euro is least expensive to make, then Frac and MOTM, and finally Dotcom is most expensive.) Let me know if this would fit your needs, and I'll see what I can put together.

Great news Randal, looking forward to some building.
I might be into the euro panel, any chance you could post a design? Does the price include engraved or screen-printed graphics? Also when do you think you'll have your site up and running - is that where the building details etc will be logged or do the boards come with a full set of instructions? |

Hello Usine Karate!
And I'm looking forward to seeing the results!
Quote: | I might be into the euro panel, any chance you could post a design? Does the price include engraved or screen-printed graphics? |
Here's a wide and narrow prelim Frac panel. The Euro simply moves the title and attributions to accomodate the different mounting screw placement. The wide one is fully tricked out, the narrow has minimal features to save space. Each has the LEDs laid out such that they will chase a circle. Different disciplines orient the 360 differently, but I think the version shown on the narrow panel makes the most sense for use ihere? The large panel has no markings near the LED's. It just cluttered things up IMO. There are at present no pot graduations. I'm open to comments on that? FWIW The black circles are a bit larger than Blacet style REAN knobs. Certainly something like the Davies 1900-H will fit. Blue circles representing jacks are BLacet size as well.
I'll post a Euro version with cliff sockets and the changed mounting and labeling soon. And an MOTM and Dotcom version.
The wide version here is Kitchen Sinked, to use Scott's terminology, and requires an attenuverter be built on a daughterboard. I've two daughterboards nearly completed for this module; each will eventually be available as pro style PCB along the lines of John Loffink's pot chiclets, but the single sided PCB for each will be presented soon as fully DIY capable press-n-peel. They're a bit like smaller versions of the universal boards by Tellun, bit not quite the same having a few unique features. After all those Tellun boards already do a good job at what they do! No need to duplicate them! I think you'll like what the daughterboards I'm doing bring to the table. (And they'll be useful on many modules, not just those produced by me. Yes, hints galore )
The panels will be engraved and/or screen printed depending upon the success of the offer. I have facilities to do both. I also have a couple gallons of the carbide black polane paint Paul used on the old MOTM panels, but it's near the end of its life, so I'm not sure if it'll work for any MOTM panels. Euro and Frac will be anodised clear and black, respectively. Dotcom will likely be anodised black as well, but paint may be used instead. We'll have to see how it plays out. If volume is low, it might make more sense to simply engrave or screen a dotcom/MOTM blank. But the Euro and Frac will be done in-house. The point is to help those for whom frnt panels are the stopping point to getting modules built.
Recent thereads suggest that htis myay be fairly widespread. Shaeffer are nice, but IMO too expensive. I think we can do better.
Quote: | Also when do you think you'll have your site up and running - is that where the building details etc will be logged or do the boards come with a full set of instructions? |
Well, I've been saying it will "shortly" after the QFG's ship, so that means pretty soon! Sometime this coming week. Build docs will be spread betweeen the site DIY reference area (for things common to all kinds of DIY building, like part selection, planning, etc.) and a module specific PDF as has become the norm. I have to admit, I'm a little intimidated by some of the simply awesome work done by others which has preceded me. But I think you'll be able to get these built successfully at any rate. I'm doing final tweaking of these and will release them in time to coincide with your receopt of the PCB's I'll get the parts list doc up soon. You won't go wrong using the original that Scott and Thomas posted if you're using 15V. The additional parts are nearly all covered by the MPK's which most of you chose to purchase anyways. This is not a complicated module.
More soon, but please know that this is not the only important task I have before me right now. I'm giving it as high a priority as I can; but it may take a few days to get all the docs up. (I welcome comments about the panels, but they're not as high a priority as the PCB's right now, to be sure!)
Kind regards, Randal

Curious, are you using my method of porting front panel designer over to cnc files from the tutorial? If so I want props! *wink* |

Must say I prefer the wider and fully featured euro version better. I have quite a bit of doepfer and it can seem squished at times, mainly on the HP. I tend to make panels wider than necessary and spread pots out that way to give myself a bit of room. Also I make first panels out of 3mm MDF as it is free for me and I have the facility to cut it to 0.1mm accuracy if necessary. My plan is to upgrade gradually to aluminium when I get the chance (money), with no delay in making sounds - at 3U the flexibility (bounciness) of MDF has never been a problem. Randal, if you are aiming at having the facility to make panels for not only your designs but others (for example, mine) a la schaeffer that would be great - not sure if you are though?
In my view the high cost of euro cases is likely a big reason that modules tend to be 'squeezed' on their horizontal axis, if this cost can be reduced (eg making diy cases out of wood etc.) there is no reason to look at each module like MOTM, only it is on it's side - if you get what I mean
Fonik has made some nice looking, spacious euro modules, simple things like varying how the pots are arranged yet keeping to a standard spacing enables easy 'at a glance' module recognition. The number of times I can't find the VCA etc. on my modular is stupid (especially having built and layed out the thing!)
Also I think some kind of marks around the pot would be good for accurate setting up of patches, even without numbers, though I can't help thinking that the layouts as they are have a clean 'laboratory' elegance and it is possible that the lack of scales contributes to that?!
Already,
Usine |

Hi all,
First, to answer Loss's question, YES, there are more THD107A QFG PCB's available.
Most of your previously ordered QFG boards have been shipped. Here are the Schematics and BOM to go with them. Also I've included an enlarged Component ID REF /placement diagram, which unfortunately is a little less crisp than the original due to its being backplotted from the original Silkscreen Gerbers with limited software to do the translating.
In the build document (posting soon) there is a list of component locations by x,y coordinates. I used Thomas's original part reference numbering, and I've read here that some of you prefer component numbering that is associated to the PCB instead of the schematic. Since that's not possible without changing the original part numbering, I hope the X,Y component location info will be of some use.
I believe the Schematics to be an accurate reflection of the THD107A PCB, but they were drawn after the board, and so are not linked directly to its creation. So I'll appreciate hearing of any mistakes you may find. It's been checked and re-checked, but I just want to give a heads up that the board itself was created from Thomas's original schem and hand routed, rather than being electronically linked to this schematic.
I'll add that doing a BOM with full part ordering info for an unknown variety of builders is MUCh harder than I originally thought it would be for such a simple board! I tried to pick the less expensive options, but I think in the future I'll just spec the parts fully and leave the part numbers to someone else! As it is, I've included a list of URLs at the bottom of the BOM to help with some part decisions I simply can't make for you, without knowing more about your format and ultimate use.
Kind regards, Randal

And of course somehow the physical act of posting reminds the mind of what it left off!
I set up an independent dirty GND for the LED's. So there's a link which goes between two pads I labeled R00 on the PCB Lower right and page two of the schem (Also lower right, how about that! ) if you choose not to maintain separate GNDs. The R00 link joins the two PCB GNDs at one point, physically near the return to the main supply. Without it you'll need to connect to your system's dirty GND or the LEDs won't!
Anyways, I accidentally left it (R00) off the BOM. I've been putting a "zero-ohm" resistor (single black band) in the package for each board so you don't need to order it. And a clipped resistor lead would do as well If I didn't include the z0R. But if you were wondering what the DG and R00 were about, now you know!

Randal, these look great, but would you also mind knocking up BOM's for suppliers in other countries other than the USA? Mouser aren't very understanding for those outside the USA.

I might add it would be a full time job unto itself. I purposely left such information out of the Klee build doc.
Other than it being a lot of work, if you list all the American suppliers and part numbers, it becomes American-centric, if you list all of the European suppliers and part numbers, it becomes Euro-centric. What about the Australian and Pac-Rim builders? The Antarctic builders?
That, and I plain don't know all the juicy supply houses anywhere but here. I figure a DIY project is being built by DIYers, and they know better where to get their parts than I do. If anything, listing something at Mouser may just put the blinders on relative newbies and they might end up paying more for something that might have been easily available down the street. If there are questions, people know where/whom to ask.
Cheerios,
Scott _________________ My Site |
