It's basically a really powerful logic analyzer. Excellent for debugging.

The school Macs had the Mighty Mouse with the tiny trackball for scrolling. It was my first time seeing a Mac, but I always thought there had to be a setting somewhere that would let you move the cursor around with it. Spent many computer l

Technically I learned the drag and drop Lego Mindtorms first. Don't know what kind of habit forming research there is about that. Any of them are a big step from "computer is just for MS PAINT" to "wow, it actually did s

It's a different category, but I can't tell you how much learning programming in BASIC and learning hardware on Z80 got me to understand how computers actually work. BASIC is just plain approachable - turn on the computer and it&#

Haha, that I did! I spent a good while narrowing down that very list to pick one of my first ones out last year. By coincidence, I ran into the very same part number in a completely different circumstance a few months later. What are the ch

Lots of assumptions off a comment that is mostly just me stating my preference for short and unique part numbers. Nothing would be wrong with ESP32xx ESP33xx, ESP34xx, etc. Espressif only have 312 SKUs [0]. You're telling me nobody cou

Funnily enough, E-Meters are known to be made with fairly high quality components. https://hackaday.com/2018/07/19/whats-inside-a-scientology-e... I guess if you have tons of cash rolling in, you might as wel

You need a transceiver chip which then hooks up to the Ethernet jack. Usually have to do this for any interface when the signals don't come in right at logic level, like CAN, RS-485... although it's not always exactly 'just&#

I kind of wish these all weren't called ESP32. ESP8266 and ESP8285 -> ESP32 made sense, but now we have 10+ different versions with different features and different architectures. Kind of like how in every thread involving a Raspber

I have family that would gladly use FacebookOS if such a thing existed and automatically loaded that and only that website as soon as you turn on the computer or phone.

There isn't a lot of equipment that scares me, but eye-permanent-blinding lasers through open air is one of them. It seems like this device could be made safer by replacing the laser with a loaded gun, because generally, you'll be

I don't know man, I was just trying to follow the official build instructions. If that's not Meshtastic I don't know what is. The (lack of) reliability in the network is the main issue with it though, but that's already

It's pretty hard to imagine anyone "getting serious" with these tiny radios designed for reading gas meters and weather stations and using that to build some kind of off-grid alternate Internet. I'd almost have more fait

This is a project I have seen a number of times, where people make a low power transmitter to set their WWVB wall clocks and watches which don't get a reliable signal.

That's a shame. CHU is usually the first thing I look for when I turn on my shortwave radios (which I guess isn't all that often). Usually comes in a lot better than WWV in my area.

Using reference images is a huge step for this sort of thing. The text-only approaches I've seen before were never going to be that good even with "perfect" AI, simply because describing 3D objects in text is not something th

The normal people are the ones not writing comments, but I'll give you one 'cause you asked: I'm a Solidworks user. Most Solidworks or other pro CAD users would consider OpenSCAD kind of like MS Paint. Yes, you can draw the M

If you are much into Arduino type things you will come across 1-wire as one of the most popular temperature sensors is a DS18B20. The only place I've run across it in the wild is inside an SGI Octane. I thought it was a battery to repl

Also celluloid (made from cellulose), which I was pretty surprised to learn is about 170 years old. Plastics from oil were mostly invented after WWI and took off during WWII, but they had some kinds before that.

I discovered the same thing a few months ago with my home's furnace (which was a bit of a shock, because one reason for picking natural gas is so you can still have heat when the power is out). It runs just fine on a pure sine wave inv

If you decide to get a Bambu anyway, let me heartily recommend against an H2D. It did "just work" for a while, but then the print cooling fan went bad. On my home Voron, this would be a 5 minute fix. On the H2D, it is this [0]. Yo

My region has the Japan voltage version on Amazon for $210. https://www.amazon.com/Hakko-FR-301-Desoldering-Tool/dp/B07B... I think the one I had was the ZD-917, which I don't even think anyone makes anymore.
