#372I made a baseball bat that uses explosives to add a bunch of energy to your swing and hit a baseball really far. It uses the explosive blanks normally used to shoot nails into concrete (e.g. ramset). It worked way better than I expected, didn't have a kick, and turned out to be just a really neat thing to look at while sipping a frosty beverage. I also made a video about it if you're interested: https://youtu.be/Puo6…
Is that your favorite project so far? Too many to pick from!
It's definitely my favorite

#373Earlier quoted context omitted.
I have ten year old Sonos gear that still works. The feature I wish the speakers had most? A line in jack so I could use them with something other than apps. That is a kind of future proofing all powered speakers should have.
The Sonos product team had a completely unexplainable aversion to line in jacks, to the point where you almost weren't even allowed to discuss it. I suspect it was a lot of fairly self-interested resume padding for some PM resumes. Nobody there was going to make their next career move as "innovators" shipping a technology that'd been perfected for fortyish years before them.
And here we have the person who knows how to graft one onto the PCB. Is that possible?

As explosive as the bat was, I feel like the most explosive thing you’ll ever make is your YouTube channel. One of very few instant-subs for me.

(I purchased the plans for it, though. It was not my design.)

#377One of my favorite things that I’ve made in terms of utility is a little leather belt holster for my AirPods. I wear it almost every day and enjoy the functionality of it. I made it for the first generation AirPods case, but it still fits the wider AirPods Pro case sideways, so I didn’t have to make a new one for those.

#378A turbo Miata. Not that unique but it was a collection of all the fabrication I did in the last few years. Taught myself how to weld and it was super fun to make things for it.
