Per BOM, pre-installed parts are on main board along with 102 of these caps. The rest (566) are on boards with no pre-installed parts. If someone has access to a laser cutter to make solder masks, and a reflow oven, that should make quick work of this.

Meanwhile, I asked Roman is this is just a BOM oversight. If all of these need to be manually installed, his production cost for completed units is going to balloon.
Tony I asked Roman this direct same question and his response was that if it does not say pre-installed, then you need to order it and install it. He was very clear on the need to install the SMD caps in the build. I am looking for his actual response right now.......Steve

From Roman Filippov via FB: All populated parts are indicated in a bom, you only need to solder smt 0.1uf capacitors and one soic8 chip on a output board, it's easy job for anyone

This could be troublesome for some newcomers. That's an enormous amount of smd for anyone (including veterans)... especially without proper tooling.

I'm researching now how to convert my old toaster oven to perform reflow.
This means nothing to me... Oh, Vienna!

I agree, but due to the size of the project, it will be a fine challenge for many even with experience. This will be one hell of a DIY for someone who has done little to no DIY in the past......Steve

on the plus side, any DIYer who does successfully install that many SMT caps will certainly qualify as an 'SDIY SMT Guru' :hail:

from our view, the question will be how many thru-hole SDIY people might actually decide they prefer SMT once they're used to it?

Well if we lack smt soldering chops now, we won't afterward. To be honest, if I had the choice between 668 smt or through hole caps, I'd take the smt.

Once you get the hang of SMT its not bad at all, but it takes a bit of practice. I am glad I have built 3 O&Cs I really EFFED up the first one, but I figured it out and they have over 70 SMT parts to solder.......Steve

The Deckards Dream website needs to be updated. In the FAQ section of the website, it states “The kit ships with all SMD parts preinstalled and only requires through-hole soldering, meaning even beginners should be able to build this project.”

Yes why the change from "only requires through-hole soldering" to "requires soldering 600 SMDs"? How did that come about?

A Very good question!
That’s not funny to solder more than 600 SMT caps.

Before I built my O&C and crOwBX I bought a handful of SMD practice boards on eBay for next to nothing. The quality of the boards is somewhere between terrible and quasi-acceptable but they do the trick in terms of getting your feet wet re: SMD and practicing your technique. Now I fear not the surface mount component.

SynthCube Delivers!!!!!!!!!!!!!!!!

Post by needspeed » Thu Oct 05, 2017 7:12 pm

SynthCube delivered today with very few back-ordered parts so just for poops and grins take a look at Deckards Dream's guts!!!!!!!

It is going to take a long time to inventory this :eek:

I remember having read the text under the DIY kit I ordered. And it clearly stated at that time already that the bypass capacitors would be SMT 0805 (a reasonable choice and size for DIY soldering in my opinion). The amount wasn't clear there though. But already the preliminary BOM contained well over 600 SMT capacitors... So while I get that this might be astonishing to some when reading only this particular entry in the FAQ we have to see that the question right under it already steps down to only the SMT chips that are presoldered...

It's a large project and if each and every chip has two bypass capacitors (one for each power rail) and there are around 25 chips per voice card alone (as seen on the voice cards on the instagram account)... this adds up quickly...

0805 soldering

Looks pretty straight forward...

The confusion comes from reading the FAQ section which clearly states all through hole components, so the site is not consistent. Therefore the angst being expressed by some folks which is understandable......Steve

Much rather than solder 600 through hole caps.

after a short review (2hours) of the Mouser BOM:

there´re a many positions with a pricebreak by ordering the next pricebreak like 100x 1nF c0g capacitors intead of 46 of them.
