    Arrived back in town to find my boards waiting for me on the kitchen table; nice :)

    As for sourcing components, I don't have any of them (this is going to be my first real electronics project) so suggestions on where to get some of the more exotic components would be appreciated.

    I notice that digikey isn't the one-stop shop for this one's BOM.

    If someone wants to do organize the BOM, I'm in. :)

    sorry, not organize the BOM, organize a GB... though in searching through a bunch of stes like Digikey and Farnell, it doesn't look like a GB would be worth ith

    Info for Brits:

    Everything is available through either RS components or Farnell UK with the exception of the LT1230. Linear Tech have this part but shipping to the UK is rather expensive for cheap guys like myself. Digikey have an SOIC package and an "Aries" SOIC to DIP adaptor is available from Farnell for about £7.

    I'm having a hard time finding the polystyrene capacitors in the US. Neither Mouser and Digikey have these in stock.

    Can another type of film cap be substituted for polystryrene in this application?

    Hello Gray5596,

    You can use others good capacitors like polypropylene or mica.
    I recommend first polypropylene which are excellent and reasonably priced.
    If you need a better temperature stability of the output frequency, Mica type will be the best, but they are very expensive.
    Regards.

    And's i'm happy for those have receive their circuit boards. :)
    I will post soon a new diy project to build a LNA/RMS meter box,
    allowing to measure noise level down to microvolt.

    Frex.

    LCR polystyrene caps listed in BOM are available at Newark (i.e. 47 pF part no 97K0243)

    rest of the world: Farnell

    thanks for the info.. interesting new project is going on there.. are you also making new ADC boards available?

    regards

    Valeriano,

    For the ADC board, i can organize a group-buy but i'm not shure that enough DIYers would be interested. It's a 4 layers PCB, the price (including worldwide shipping) would be about 40 each if at least 5 PCB are ordered.
    If enough people ask me (by PM), i would open wiki page for a PCB group buy.
    Regards.

    Frex
