I decided to make a cable interface for input and output of the Raspberry Pi (GPIO) for connect to Protoboard.
The GPIO connector has 26 pins. I found in my scrap, flat cable with 26 pins but one pin closed in the connector, ie with 25 pins.
I saw in the description of the GPIO pins that is ground pin .
So it will not be missed, because there are other ground pins on GPIO. Then I will make a hole in the cable connector in order to connect the GPIO.
I used a few bars of pins (easy to find). I crumpled the tips of the bar with smaller pins and then soldered the two bars - see the photos.

It was very good. Although not tested.
Remember that the interface uses levels of 3.3 V.
So do not plug in circuits that use 5V!

Re: Flat cable GPIO for Protoboard
I've been trying to create one of these myself, but with a smaller footprint.. Though, I may end-up making this version myself.. The hard part, is finding a source for PC board that is plated through.. Radioshack no-longer has anything other than single-sided..

Re: Flat cable GPIO for Protoboard
I know that making stuff is often fun - I do it myself a lot, but sometimes it's easier to just buy something - especially if not 100% confident in your own design/solder abilitys...
I have one of their original "cobbler" boards, the the latest "T" one is looking like it might slip into my next order: https://www.adafruit.com/products/1105
(Although I understand getting stuff into Brazil is somewhat problematic at times though!)

Re: Flat cable GPIO for Protoboard
seems to be a selection of breakout boards here: http://www.hobbytronics.co.uk/raspberry-pi
i've never seen a direct ribbon cable to breadboard pins adaptor though.
i generally just use male-to-female header leads for prototyping.
