I'm thinking about making some bus boards and want to know if anyone has a schematic/parts list. I want to pick the parts up at lunch time but I'm at work and can't open my case up to see what's in them and how they're wired.

i intend to do that as well. the only problem is that i cant find vero board (strip board) here in the states anymore! you basically dont need those leds or anything in the busboard, just need strips that run horizontally behind the busboard. i suppose you could solder wire across all the points on the back of some protoboard but that would be a PITA.

So I'm basically looking at something like this then:

if I understand correctly, no, they don't look like that - it's one continuous trace all the way down. As simple as it comes, and if you get the proper strip board you basically only need to solder the connectors on there and that's it.

right. the extra column on the power headers is superfluous. make sure you have horizontal continuity on every row.

why not just using a stripboard? it is nothing but a buss actually...

BTW i once thought i needed an etched bus board, so here it is:

For those of you searching for vero/strip board in the US, take it from me and abandon hope; strip board (as well as pad-per-hole board) are slim pickings in the US without paying a ludicrous price.

Reichelt has affordable vero board but unfortunately also has ridiculous shipping policies ensconced in archaic procedure. My recommendation is to purchase vero board through JayCar. Here's a link: http://www.jaycar.com.au/productResults.asp?CATID=&SUBCATID=&keywords= veroboard&part=&SPECIAL=&form=KEYWORD&ProdCodeOnly=&Keyword1=&Keyword2 =&pageNumber=&priceMin=&priceMax= There are smaller sizes available, but I recommend purchasing the 95mm x 303mm boards and cutting them in half lengthwise with an exacto knife - easy solution for two bus board strips that can comfortably hold about 12 module connection headers with no awkward cable spans and room to spare for solid chassis mounting and PSU connections. SPBaker also posted a thread discussing some of the options and methods here: http://www.muffwiggler.com/forum/viewtopic.php?t=1406 , although I would recommend a star grounding/distribution method rather than daisy chaining.

JayCar has a minimum order for overseas shipping but it's only $25 AUD I believe, which can be easily covered by purchasing a couple vero boards and the headers to solder into them. For about $30 USD and a touch of DIY you can build the rough equivalent of 4 Doepfer busboards using this method.

www.futurlec.com is good & cheap for stripboard (though orders take a little while to arrive -- just use the standard shipping rate)

(though, strangely, their website isn't working for me right now???)

I'd often recommend putting V+ and V- LEDs in just for testings sake - it takes 30seconds and can really help with troubleshooting!

the mouser part #:
854-ST3U
854-ST6U
but be warned. expensive!

So for building a pseudo-star-distributed system it would be rather difficult to connect each dist. board directly to the PSU terminals - would the approach be to do a tightly clustered "distribution board for the distribution boards" ?
