This week, Hackaday’s Elliot Williams and Kristina Panos joined forces to bring you the latest news, mystery sound, and of course, a big bunch of hacks from the previous week.
In Hackaday news, the One Hertz Challenge ticks on. You have until Tuesday, August 19th to show us what you’ve got, so head over to Hackaday.IO and get started now! In other news, we’ve just wrapped the call for Supercon proposals, so you can probably expect to see tickets for sale fairly soon.
On What’s That Sound, Kristina actually got this one with some prodding. Congratulations to [Alex] who knew exactly what it was and wins a limited edition Hackaday Podcast t-shirt!
After that, it’s on to the hacks and such, beginning with a ridiculously fast Benchy. We take a look at a bunch of awesome 3D prints a PEZ blaster and a cowbell that rings true. Then we explore chisanbop, which is not actually K-Pop for toddlers, as well as a couple of clocks. Finally, we talk a bit about dithering before taking a look at the top tech of 1985 as shown in Back to the Future (1985).
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!

- Kristina’s Picks:
New math was about using math education as an excuse for indoctrinating a way of thinking. There’s a book, “Why Johnny Can’t Add: The Failure of the New Math” (Morris Kline, 1973)
It was trying to teach independent abstract thinking instead of math, as a panic response to the apparent scientific lead of the Soviet Union, to children who were still at the age of learning how to follow instructions rather than thinking in abstract terms. It was based on the hope that if you throw the children straight into the deep end of the pool, they’d learn to swim better – but then not even the teachers knew enough high math to teach the material, so it all devolved into drilling these new concepts out of the textbooks like they were drilling 1+1 before and not only did it fail to teach independent abstract thinking, it failed at teaching elementary math.
Thanks! I totally missed out on the New Math when it came and went.
