I can use a 4 port passive hub to program SSCs right? I would like a dedicated bench SSC programmer/tester. Also, anything inherently wrong with scavenging an old laptop PS to power it? I have one that is 2A @ 12V and another is 4A @ 12.6V. I would prefer to be able to power a full string for testing, is the extra .6V an issue? Another other ideas appreciated. Thanks.
