For a somewhat long running project, I was looking for 8-pin jumper wires, and had even gotten some headers and ribbon cable to see if I could make them myself. However, with the prospect of stripping, crimping and soldering some ~200 pins, it just didn't happen. That's why I was happy to find these pre-made cables from emartee.com. 4-pin and 5-pin wires are common, but except for Alibaba, I've not found 8 pins anywhere. They are available in lengths of 20, 30 and 60 cm. Ordering from emartee was smooth, and delivery from China was less than two weeks. Their prices are maybe slightly higher than what you find elsewhere, except for said 8 pin wires...

Below are just some fun pictures, with the last one hinting at the LED matrix project. More about that later.
