Creating jumper leads from ethernet cables - connect multiple components












2















I've bought some crimpers and a dupont connection kit and I'm planning on reusing some old cat5 ethernet cables I have.



Is it reasonable to connect two devices to the RPi via the 8 wires in the cat5 cable? For example connecting four jumpers to 4 GPIO pins on the RPi connecting to one device and the other four cables in the cat 5 cable to four other jumpers on the RPi connected to a second device?



This is attractive because it keeps the wiring (that will be visible) reasonably tidy but I'm not sure if this approach is technically appropriate.

          Lots of folks do that.



          You may need to add some small capacitors on long cable runs to reduce and RF interference that a long unshielded cable can pick up.

          Restoring from pg_dump with foreign key constraints

          5 2 In restoring a database from a pg_dump , a number of errors are being generated and the whole table is subsequently being ignored. An example: ERROR: insert or update on table "channelproducts" violates foreign key constraint "fk_rails_dfaae373a5" DETAIL: Key (channel_id)=(1) is not present in table "channels". Interestingly enough, I've noted that all these instances are popping up because of the sequence of loading. channels is after channelproducts both alphabetically and in the file and thus I can understand why postgres complains about having to create a child without a parent. caveat: the foreign key is being generated automatically by rails 4.2: I could remove the problem at the source but that still does not really solve the problem... version: PostgreSQL
