Radio Shack used to publish beginners handbooks for electronics that had all kinds of nifty little circuits in them. I I bet you could do something like that with a few flip flops using the output to the single HDD LED as a strobe. I think I had a couple of those books at home, I'll see if I can find them and make you a copy, they were small maybe 50 pages or so. I'll trade you for some help with a DNS. :-) -----Original Message----- From: Yaron [mailto:jethro at freakzilla.com] Sent: Thursday, July 19, 2001 9:23 AM To: TCLUG Subject: [TCLUG] OT: Electronics Hackers? Hey, Ok, my knowledge off electronics is enough for me to know how to replace LEDs on my machine when they die or are too boring. But that's pretty much it (ie, I can solder somewhat, and I know how to reconnect wires). When I was at The Shack getting new LEDs, I saw one of those LED-Basr things (you know, thing that has 8 LEDs in a row) and I thought, wouldn't it be cool to put that on and geet a Knight Rider thing going when the power was on? Or when the HDD gets accessed? Now, I know enough THEORY to know that you need something that'll take the power in from one LED and, uh, round-robin it between 8 LEDs. I know how to tell DNS to do that, but not real hardware. I know a lot of people on the list are electronics geeks (what's happening with the analog RAM meter, btw?) so I figured I'd ask. Is there like a Beginner's Guide to Hacking Electronics website or something?
