If you have any empathy at all for those of us in the journalistic profession, have some pity for the poor editor at the Chicago Sun-Times, who let through an AI-generated summer reading list made up of novels which didn’t exist. The fake works all had real authors and thus looked plausible, thus we expect […]
If you do anything with electronics or electricity, it is a good bet you have a multimeter. Even the cheapest meter today would have been an incredible piece of lab gear not long ago and, often, meters today are lighter and have more features than the old Radio Shack meters we grew up with. But […]
The modern hacker and maker has a truly incredible arsenal of tools at their disposal. High-tech tools like 3D printers, laser cutters, and CNC routers have all become commonplace, and combined with old standbys like the drill press and mini lathe, it sometimes seems like we’ve finally peaked in terms of what the individual is […]
These days, if you are in the market for a capable digital voltmeter, you might as well consider getting one with an oscilloscope built-in. One choice is the Owon HDS160, which [Kerry Wong] covers in the video below. The model is very similar to the HDS120, but the multimeter in the HDS160 has more counts–60,000 […]
We’ve all seen those cheap bench power supply units (PSUs) for sale online, promising specifications that would cost at least a hundred dollars or more if it were a name brand model. Just how much of a compromise are these (usually rebranded) PSUs, and should you trust them with your electronics? Recently [Denki Otaku] purchased […]
If you’re into electronics you can never have too many digital multimeters (DMMs). They all have different features, and if you want to make multiple measurements simultaneously, it can pay to have a few. Over on his video blog [joe smith] reviews the new Brymen BM788BT, which is a new entry into the Bluetooth logging […]
Current measurements are not as handy as voltage measurements. You typically need to either measure the voltage across something and do some math or break the circuit so a known resistor in your instrument develops a voltage your meter measures and converts for you. However, it is possible to get non-contact current probes. They are […]
[Project Farm] has a video in which a wide variety of AA cells are analyzed and compared in terms of capacity, internal resistance, ability to deliver voltage under load, and ability to perform in sub-freezing temperatures. Alkaline, lithium, and even some mature rechargeable cells with a couple thousand cycles under their belt were all compared. […]
There aren’t many people who could do an hour-long video reviewing an oscilloscope, but [Kerry Wong] is definitely one of them. This time, he’s looking at a UNI-T MSO2304X 300 MHz scope. The review might be a little long, but the scope — like many modern scopes — has a lot of features for measuring […]
[Maker’s Fun Duck] has a recent video review of a cheap thermal camera from a company called Kaiweets, which you can see below. It checked all of his boxes: It was standalone, handheld, cheap, and not too cheap. The question is: does it work well for the kinds of things we would do with such […]
