Quoted from KenH:
make a 'pass thru' type connector using some stripboard, resistor SIPs, and connectors/headers, like this
That is exactly my prototype. (I'll try to post pics this weekend).
Sadly, my project (the $30 plug-n-play-no solder at all-solution) has not moved much. I can't find PCB production low enough to reduce the cost to a reasonable amount (e.g. I was hoping for under $20 in fab+headers, pins, SIP resistors for 3 boards + wire + solder) meaning about a $30 sale price once you factor in my time to design, order, solder, ship. Unfortunately all quotes I'm getting are hugely above that, giving a $40 cost of goods alone for the 3 boards each machine would need; and no one is gonna pay $50 for a solution. Especially considering the prototype was done with about $6 in core parts (resistors, SIP headers + pins), but about 2 hours of bending wire, cutting, fine soldering, etc...
I'm still looking to see if I can find a more reasonable PCB fab'er for these things to get them done yet for a $30 sale price per machine.
Quoted from Hellfire:
seriously $30-$100 for a board? lol you can get a 100x restistors for like $1.50 shipped to your door lol.
I agree $30 seems like a lot. But how many people
a) can solder successfully (no damage)
b) can solder to oxidized metal and make it stick
c) want to spend a couple hours soldering to 60 some sockets
d) want to 'damage' their otherwise original hardware (yeah that's an issue for some)
and would rather have a plug-n-play solution that doesn't require more than disconnecting 4 cables and reconnecting with boards between in under 5 minutes. Nope, it's not for everyone, just like the $100 replacement lamp boards aren't for everyone; but given the requests in this thread seems like such a product is wanted.
Now if only I or the other person working on similar could find a way to cheaply fab the fiberglass+copper; it could come to reality.
