    The Stripe is Negative

    On a 1N400x diode, the stripe = the cathode. Cathode = negative Anode = positive The striped end = negative http://www.laserpointerforums.com/forums/YaBB.pl?num=1217284580 It seems to me all the graphics that represent a diode in that thread are backwards!

    Radio Shack light to frequency converter

    I was rifling thru the drawers at RS today, and I saw one of these: http://www.radioshack.com/product/index.jsp?productId=3004020 I wonder if it could be used somehow in a DIY laser power meter? Interesting!

    Forward Voltage Characteristics of 1N400x Diodes

    I was reading the DIY Driver thread, and some other threads about building a test load, etc. today at work - and I knew I had various 1N400x diodes at home in my bug box. So, I did a bit of quick research, and I found out:  for our purposes, it doesn't matter if it's a 1N4001 or a 1N4007 -- for...

    Burning:  PHR-803T blu-ray vs LG 20x red

    OK I've built two nice compact lasers so far, with the Viclight 3-AAA host & heatsink from Jayrob. They work great, I'm really happy with them. I'm using Dr. Lava's FlexDrive v3 for both of them. Blu-ray is running at 150mA. Red is running at 420mA. The blu-ray lights matches INSTANTLY, the...

    Polyphasic Sleep

    This is an absolutely fascinating read - I've got so many hobbies, so much tinkering around, so much stuff I wanna do. Eating, sleeping, etc. at times seem like such an inconvenience that interrupts whatever I'm into at the moment. This seems like a very intriguing way to go...

    Pink Floyd on PBS

    I've been watching WGVU (Grand Rapids, MI) PBS this evening while I did some tinkering work, and they've been running a fund raiser and some old steam engine train locomotive stuff all night - but they just switched to a Pink Floyd concert... Holy crap!  There are some awesome laser effects in...

    The origins of 'Senkat diode'?

    It seems like 'Senkat diode' and 'Sony 16x diode' are used interchangeably around here. What does Senkat mean?

    Have you used a PC-based Oscilloscope?

    I'm going to buy a scope.  It's time I owned one. Do a search on eBay for 'oscilloscope' and look at the pc-based ones, like the DSO-2150. Having only used Tektronix and HP 'real' scopes in the past, a PC-based one seems very intriguing to me - not to mention affordable. Do any of you have...
