Build time estimate

Thanks for your comments. Regarding the build time, I was hoping to gather that sort of information from the first builders so I can add this information to the assembly guide. I can build the 18 channels on a weekend. But that's solid work of 8...10 hours per day. I've actually done it and felt a b...

Assembly Guide Sneak Preview

I've made quite some progress over the weekend with the assembly guide. A number of Sections are still missing but I wanted to give you a chance to take a sneak preview so that you get an idea about the scope of this project. I suggest you take a look at the Sections about the "Vocoder Build Sequenc...

Preliminary Bundle Pricing

A Bundle Request Form is now available . Once I have the final panel pricing, I'll update the content. What you see in there is already a very good price indicator for the discounted run. Select the options you need for your vocoder and the total price will adjust accordingly. This weekend I will up...

Will there be other bundling options? I already have IC sockets and tempcos, and I just purchased some reliable LM3916 just for this project. Yeah, I think I can do that. I don’t mind having some LM3916 left over. I can tailor the need on the sockets and the tempcos. BTW, how do you define „reliabl...

I've tested three of them and they are working well. :nana: Based on all the feedback I've received, I'm now preparing some bundling options: First off, there will front panel options : reces...

Apart from the new power supply, I've made also progress on the assembly guide. I think that one's about 30% done. Since I haven't yet received my package with a handful of LM3916 from China, I've ordered enough from the UK for the first 12 wigglers who are going to sign up for the discounted PCB ru...

Progress has been a bit slow lately but there's been progress nonetheless. I've designed a new power supply to give wigglers an alternative and avoid running mains power through the enclosure. It's a solution based on a DC/DC converter using an external tabletop transformer, such as the GST60A12-P1J...

Hello Do you have the 12 first builders ? IF not i could be interrested, i have build several Vocoder (Elektor, L1, MFOS, Okita, and JH ) Thanks for your interest. I have more than 12 wigglers showing strong interest but I haven't announced pricing yet. A few things need to get sorted before I can ...

Tobb, thanks for the idea to use these rack washers. Bear in mind though, they'll take up a lot of space. At least enough to cover the scales. The spacing from channel to channel is 17 mm.

tobb the only one fitting at the base at Thonk's are called "small tall". But they are only offered as D type. The one found at Farnell is simply to wide at the base.

Hi Modulart_JP , your input is worth more than 2¥. the pots you are suggesting seem to fit but do you know of knobs that fit as well and are not wider at the base than the Davies knobs (13 mm)? If there is a viable alternative, I will certainly look into it in more detail. In fact, if there were kno...

UPDATE: I just went through yan6's Mouser project , compared it against the BOM, made a couple of minor updates and additions. This list now covers all IC's (except the LM3916), transistors, diodes, LEDs, all capacitors and resistors (except the tempcos) and the trimmers. Thanks again, yan6 , for d...

yan6 , thanks a lot for spending the time preparing this Mouser basket. This is really cool. I've ordered 10 of the LM3916 from a sell in Hongkong on ebay and have yet to receive them. They were sent on August 17 but I have no tracking number, so I don't really know when they will arrive. If it tur...

Hey glubsch , the resistors in the BOM appear to be around 3.5mm in length. Can you confirm that is what is needed? Is 1/8W ok where 1/4W is not specified? Thanks! Take a look at the PDF shown in the first post, page 2, the section about resistors: yes, the intent is to use ~3.1 mm resistors for ea...

Love your techno beats and electronic music, particularly considering it's all analog. Just listened to your various techno music and JaMMy's Reset Rotation while working on the construction manual.

To allow a discounted pre-run I plan to stick to the following bundle: PCBs + panel (recessed pots) + custom socket . There are a number of reasons that I prefer to do it that way and it sums up to simplicity and manageability. Things may change after the pre-run, but I'd be really happy if you dec...

It appears the general consensus here is not to have the cavity/recess on the pots. Maybe this project could be offered also as PCB only, that way we can design and fabricate our own panels to suit.

I assumed that the mono pots are from the same series. Even if they are not, The stereo pots need to line up with the other pots and the jacks.

LedtroiD, I have a series of the T18 shown in your picture on the right in mono. For the reasons mentioned in my previous post, they won‘t work for the bundle I am planning to sell (PCBs + front panel).

From the pictures I've seen, you can see them only when the knobs are removed. paterursus , thanks for pointing this out. Tobb , just look at my web page where I've posted two pictures at a fairly steep angle and rejudge. With the cavities shown, there's about one millimeter space between the knob ...
