[sdiy] PARTKITS for Jürgen Haible designs - 1 - String Filter

[Tobias Schilly]

Hi fellow DIYers,

it is quite obvious that Jürgens projects are very popular, and it is very much likely that this will still be true in future. As many of you, especially those of you not living in Germany, very often run into trouble sourcing special parts for Jürgens designs, I decided, encouraged by Jürgen himself, to provide complete part kits for his projects.

Information on the specific projects can be found on Jürgens site: http://home.debitel.net/user/jhaible/hj.html or on electro-music.com: http://electro-music.com/forum/index.php?f=159

Originally i intended to start with the Scanner project, but hey, why not the String Filter?
As Jürgen is already shipping the PCBs for the filter this obviously is a cold start, and i canŽt completely rule out the possibility that improvments have to be done at one point or the other. ThatŽs why i see this as some kind of test run, and would like it to be understood as such.

Nevertheless, the kits will of course be complete and of high quality. I will also try to get my coordination right and send the parts immediately after I received payment. 

About the kits:

Of course the kits contain all parts included in Jürgens BOM (well, kinda sure, right?) I will consult Jürgen about the parts I choose for the kits, i.e. I will provide Jürgen a partkit for the production run board he always builts before shipping the pcbs to ensure functionality.

If selected parts are required I will provide 2 options: either a kit that contains parts with tight tolerances, or a kit with selected parts, which will obviously be a bit more expensive.
The same principle applies for alternative assemly options (see Tau board -> either CA3046/86 or more expensive SSM2210/LM394).

When talking about costs: the kit price is orientated on what one would have to spend if he would buy the parts in the correct quantities needed for the project (e.g. parts ordered at Reichelt, Banzai, Digikey, Mouser etc).

The kits are not meant to be low-cost grab-bag, they are more like a good opportunity to get a complete, high quality parts kit for a moderate price without much effort. I think this absolutly meets with the qualitiy of Jürgens projects.

Ingredients:

- Metal film resistors
- Tempcos: PT146 from Precision Resistors
- Machined pins sockets
- Electrolytic caps: Panasonic FC series
- Foil caps: depending on value Panasonic Polypropylene (2% tolerance), Panasonic Stacked Metal Fil (5%) or Xicon Greenies (5%)
- Ceramic caps: NPO/C0G if possible, X7R otherwise
- Styroflex/polystyrene if required
- Semis: no ebay junk. I get my semis only at Segor and Banzai, in special cases directly from the manufacturer (like SSM2210...)
- All parts are seperatly packed in labeled plastic bags
- board connectors with attached cables, open on one side

IŽm still not sure if I should also offer extra pot and jack kits, as this is extremly depending on personal taste and requirements. Input on this is very much appreciated!!!

All of that means for the String Filter:

Kit: 120 € / 190 US$

Shipping: small parcel via DHL
in Germany: 5 € / 8 US$, insured 8 € / 13 US$
Europe: 8 € / 13 US$
Rest of the world: 14 € / 22 US$

Insured shipping outside of germany is of course possible, but expensive, and therefor iŽd ask you to contact me that we can figure something out.

Payment: within Germany and Europe I prefer bank transfer, Paypal otherwise.

To find out how much interest in those kits exists please reply to this mail. I plan to proceed to the next step and ask for binding orders in 1 week from now on, if there is enough interest. And then: letŽs go! 

Please also fell free to ask any questions and give me any suggestions, cause please remember: this is a quite rapid start...

IŽm really curious about your input.

Best wishes,

Tobias.
