It's a hot one at both microphones, as Elliot Williams and Kristina Panos wilt in the heat with ice lollies and freezer packs. But still, we persevered long enough to make a podcast.

In Hackaday news, Supercon is on! It's going down in Pasadena, California, but the talks will be somewhere slightly larger, with a courtyard instead of an alley. Get your talk proposals in now! In other Hackaday news, we still have our Frikkin' Lasers Contest going on until Thursday, July 23rd.

Interestingly enough, we got a comment on an older article from none other than [Michael J. Van de Graaff], whose grandfather invented the Van de Graff generator and was "quite upset" when plans for a DIY version appeared in Scientific American. And finally, Google Earth's desktop client is being discontinued, but you can still travel the globe on your phone, or in your PC's browser.

Not only do we have another triple mailbag this week, we have another failed attempt at guessing the Sound by Kristina. However, [Alexander] knew that it was CD-ROM drive a-spinnin'. Speaking of What's That Sound, be sure to let us know your ideas for the new prize.

That sounds like a lot of preamble, but we quickly get to a full slate of hacks, a couple of which are pretty retro in retrospect. Check out the links below if you want to follow along, and as always, tell us what you think about this episode in the comments!
