The 208 Hub - available now

Author The 208 Hub - available now
papz
Here's my new hub to plug 3 cards side-by-side to a 208 or Easel.
Or even up to 6 thanks the rear edge connector of the ToolBox series cards.

    3mm thick 4-layer PCB for best stability and rigidity
    M/F stackable gold plated banana plugs to access the panel banana sockets used for mounting
    Gold plated transfer card
    Easy plug and play design
    Jumpers to use the 208/Easel's +/- 15V rails or the optional +/-15V PSU powered from DC 12V (the Cincon external block) to relieve the 208/Easel's own PSU if more than 3 cards are used together
    Should work with any existing card or expander


PCB sets for original 70s 208, 208p, 208r and for 208e (BEMI/Buchla USA) are available now on http://www.portabellabz.be/hub.html

Price is 160€ shipped for the PCB set (not a mounted hub, no other parts included).
Manufacturing costs of this 4 layer thick PCB with blind vias are over 4 times the ones of a common PCB.

5 edge connectors : $6.60 + shipping on ebay
8 banana plugs : £12.75 + shipping on ebay

Will there be a black version of this as well?
BooleanYulian
Fantastic.. I love it.. I am interested in the the BEMI version as well !!

Thank you !
papz
Thanks cool

I could do a black version but
- full pre-payment will be needed
- I'm not sure the PCB panel of the black Easel is rigid enough to ensure stable mounting
- I know no black LW-N28A2G edge connector that fits the Hub's eyelets (thin lugs are needed)

Is it possible to get one for only 2 cards?
papz
You could buy a Hub and cut it between the second and third connectors. It should work in theory but I don't recommend it, the internal traces (it's a 4 layer PCB) are very thin and close to each other, this might cause unwanted shorts.

For 2 cards, I'd rather use the BEMI doubler or the ToolBox / BOB's rear edge connector.

The Hub works as is with 2 cards though... You're not obliged to use 3, and maybe you'll want to use 3 some day. hihi
