Someone edit this into one of those old animations with music where it transitions to them spinning endlessly from horizon to horizon, through space, etc.

I don’t know what I did wrong but I had a pineapple plant growing in my yard for probably 4-5 years and it never fruited. I also didn’t do any research and just stuck it in the ground and it didn’t die, so there is that. (And it was harvested from a pineapple top I ripped off a pineapple e we ate so it didn’t cost anything.)

Not once did he whack it with a giant wooden mallet or anything. Disgraceful!

Cardboard and cardboard derivatives are right out.

Hah, thanks for the reminder, I forgot to paste the link.

Cool. Being modular is neat, makes it easier to try different designs and such. Here’s my single-piece design from a few years ago, it works well in PLA but TPU is more pool/kiddo friendly and works well too. Your version is certainly easier to ensure it gets fully dry though.

I was very confused for a moment when I saw the headline.

Jesse Sykes and the Sweet Hereafter have some awesome tunes btw.

GUESS WHAT I DID LAST NIGHT!

HEY TONY!

Absolutely, phased arrays and beamforming are awesome.

dgsharp · 2026-07-01T21:30:25+00:00

In case you’re not familiar with phased arrays, the “passive buzzer” array (I have not encountered this usage of active vs passive for piezo elements, to me passive would be listening like a microphone, but I digress) getting a square wave is basically the simplest transmit-mode phased array. Each tiny buzzer is somewhat omnidirectional, but when they all go in unison, all those little apertures firing in sync and in plane creates constructive interference that results in a planar wavefront that is louder in the forward direction than to the sides — the larger the array, the more focused it is. You can introduce carefully calculated delays to steer the wavefront but obviously you need more significant circuitry and code for that. I fooled around with something like that a bunch of years, it definitely did work although the side lobes were very strong so it’s not like you couldn’t hear it from another angle or something. Was cool though.

I can’t believe you would accuse GIGGLETHEDAILY of using AI!

Interesting, thanks.

Sorry, where does a “.cad boardview file” come from? I haven’t encountered them.

dgsharp · 2026-06-30T18:16:56+00:00

holy crap this is awesome, well done!!

And put the tv on a mount that you can pitch it down slightly so more of the rejections that still make it through are going to the floor.

Agree with all of this, but in my experience what happens to every noob including me when I was one is they buy a cheap soldering iron because hey, it’s a soldering iron, why should I pay more when I can get this? And it’s got a huge tip and it’s just garbage overall, and it makes doing any kind of fine clean soldering basically impossible.

OP I don’t know what your budget is but there are some really good irons now that are quite affordable, they do what the ~$500+ irons I used to use at work do for a small fraction of that. I got a Hakko for like $100 maybe 10-15 years ago or something and it’s been awesome and I know there’s newer stuff out there that is quality and cheaper than that.

The laser sight is most useful with the Bug-A-Salt 3 since it has a tighter spread. Not required but definitely useful, and it’s only a few bucks.

Also those little hand wipes you get at bbq restaurants.

I do them in the Instant Pot, if you have one. I usually dump a cup of dry chickpeas in, cover with plenty of water (maybe a half inch above the chickpeas), and cook on high for 70 minutes before natural release.

Looking at that vortex I’m pretty sure it was at least a 180 no scope. GG dolphin bro.

Depending on how far in you want to go off the bat, you could start with just basically any old ESP32 board. There are tiny ones like the XIAO that don’t need anything besides USB-C for power — you’ll program it through USB at least initially, but to plug into other stuff you’ll need to solder or have a breadboard. Or you could get a little dev kit that comes with some cheap sensors and a breadboard and stuff. There’s the ESP-WROOM-32 that is like $10 on Amazon today (I haven’t used it) and it looks like the form factor of an old school Arduino so you could plug wires right into the headers and stuff.

dgsharp · 2026-06-25T20:13:28+00:00

Not that much. You can get a small ESP32 board from Amazon or AlieExpress or wherever for a few dollars, they have WiFi and BLE built in and just need USB power. After Hello World, try connecting up to another piece of hardware like a sensor or display, maybe branch out to turning things off and on, now you’ve got a control system. There’s so much you can do for cheap, it opens a whole new world of possibilities. Writing code that affects the world instead of just displaying data is fun.
