Real-world applications of phase cancellation of waves can crop up in some odd places, like your car muffler. For an example of how waves can cancel each other out, look no further than the specialized echo chamber designed to cancel out sound in your exhaust system. Link.
Have an old hard drive that no longer works? As long as it still spins up chances are you could build a clock out of your old hard drive! You will need some electronic knowledge, some common electronic components and a bit of patients. The clock that is produced isn’t exactly practical since most hard drives (especially older ones) are too loud for a clock that is to operate 24 hours a day. Thanks Doug! Link.
Whether you’re having a groundbreaking celebration for the construction of your new subterranean evil lair, or throwing a 5 year-old a birthday party, an erupting volcano cake is always the perfect pastry choice. Here’s how to make one… Link.
This is an intermediate to advanced project for someone who wants to make cool sounds. It makes a great first synth project but is interesting enough for the seasoned synth person too. When I first designed the synth I made some very lame oscillators for it and I wasn’t happy with them so I put the same basic ramp oscillators that are in my big synth and I’m glad I did. Link.
Don’t throw out those dusty 5″ floppy discs with your beta tapes and eight-tracks just when they’ve acquired real collector clout. Instead, follow Anthony Georgis’s example and use the sturdy black covers to protect updated technology. Slice the edge off with a paper cutter, and slip in your hot-off-the-burner CD... Link.
Here’s a really detailed site documenting the construction of a Lego PC, start to finish. My favorite part about this is that all the switches and lights are Lego based…Link.
The Jack Kirby Museum opened yesterday on what would have been Kirby’s 88th birthday. While just an online museum at this point, it promises to be a great resource for learning about the life and contributions Jack “The King” Kirby made to comic book culture. Largely under-credited for his role in co-creating many of Marvel’s characters during the Silver Age of comics, his career spanned over 50 years. [via] Link.
