Say, you’re starting your electronics journey with a few projects in mind. You have an ESP8266 board like the Wemos D1, a LiIon battery, you want to build a small …read more Continue reading Battery-Powered ESP8266 Sensor? Never Been Simpler
If there’s one thing about managing a bunch of keys, whether they’re for RSA, SSH, or a car, it’s that large amounts of them can be a hassle. In fact, …read more Continue reading Front Door Keys Hidden In Plain Sight
If there’s no circuitry on a printed circuit board, does it cease being a “PCB” and perhaps instead become just a “PB”? Call them what you will, the fact that …read more Continue reading Circuit-less PCB Featured as Faceplate for a Digital Clock
[splat238] had a ton of spare sensors laying around that he had either bought for a separate project or on an impulse buy, so he knew he had to do something with them. He decided to build his own digital multi-tool focusing on sensors that would be particularly useful in …read more
Weather stations are a popular project, partly because it’s helpful (and interesting) to know about the weather at your exact location rather than a forecast that might be vaguely in your zip code. They’re also popular because they’re a good way to get experience with microcontrollers, sensors, I/O, and communications …read more
Trouble in the Golden State this week, as parts of California were subjected to planned blackouts. Intended to prevent a repeat of last year’s deadly wildfires, which were tied in part to defective electrical distribution equipment, the blackouts could plunge millions in the counties surrounding Sacramento into the dark for …read more
Making a programming jig becomes exponentially more difficult after two pins and who would even consider building one if they were not setting up more than twenty boards? If it were easy for novices to construct jigs, we might all have a quiver of them on the shelf next to …read more
Watch any news panel show these days, and you’ll see that things can very quickly become unruly. Guests compete for airtime by shouting over one another and attempting to derail their opponent’s talking points. [cutajar.sacha] had encountered this very problem in the workplace, and set about creating a solution.

Remote administration of machines is a very useful tool for all manner of commercial, industrial, and home applications. Now, it’s available for claw machines, too – thanks to [Code Your Venture Free].
The project uses an ESP32 board that includes a battery case on the back for a standard 18650 lithium battery that makes getting small battery powered projects off the ground much easier. You can find them at Banggood and AliExpress, but we’re not 100% sure that they’re kosher because they’re branded WeMos, but don’t show up on WeMos’ website or their official online retail store. Anyway, it’s a …read more
