As it came up yesterday – I’ve lost the docmentation for my RS232 Signal refresher. Such a device is needed to refresh signals (from USB-converters or direct TTL implementations) to valid oldstile RS232 signals with 15 V and -15 V using a 9 battery – and yes it’s kind of magic… ;)

So searching for that pice of documentation I could just find some images of that project, that I now postet to flickr and can be found here.

Okay, so I found it out again – I’m such a lazy blogger. So to post something from time to time I’ll start blogging just to blog from here on… ;)
