A while back, you may remember that I had to put together an RS-232 level shifter for my NSLU2’s serial console. It’s been working reliably so far, despite hanging loose as a bare piece of stripboard dangling from the other end of the cable that comes out of the NSLU2.<\/p>\n
When I was in Maplin the other day, I spotted a suitably sized little black box and bought it on the offchance that it would nicely fit my level shifter. I set about cutting a hole big enough for the 9-pin D connector, and a small hole for the NSLU2 cable. At first I tried using a rotary multitool as I had seen someone demonstrating in YouTube, but it was very smelly and not particularly effective, so I finished the job much more easily with a sharp scalpel. The same went for cutting the stripboard down to size.<\/p>\n
The project took some gentle encouragement to squeeze into place, but once in place it held so solidly that my initial plan of fixing it into place with a glue gun was no longer necessary.<\/p>\n
After putting the screws on and enjoying the new neat and tidy (ish) black box which is now in place of the fragile-looking stripboard, I fired up the PC and made sure that the level shifter still worked. It did.<\/p>\n
This box is nothing special, but this is the first time that I can remember bothering to enclose a piece of electronics that I have built.<\/p>\n","protected":false},"excerpt":{"rendered":"
