Ask a Hackaday scribe who’s helped run the lightning talks at one of our events, and they’ll tell you that keeping the speakers on time is a challenge. Conversely if the staffer is trying to indicate to the speaker how much time they have left, it must be difficult from the podium to keep track […]
Developing your own film is an unabashedly analog process, which is one of the reasons people still gravitate towards it. After spending all day pushing buttons and looking at digital displays, spending some quiet time in the dark with pieces of paper and chemicals can be a way to decompress. But that doesn’t mean there […]
Reading the temperature of your environment is pretty easy right? A quick search suggests the utterly ubiquitous DHT11, which speaks a well documented protocol and has libraries for every conceivable microcontroller and platform. Plug that into your Arduino and boom, temperature (and humidity!) readings. But the simple solution doesn’t hit every need, sometimes things need […]
If there’s one thing Hollywood loves, it’s a ticking clock to create drama. Nuclear weapons, terrorist bombs, and all manner of other devices have been seen featuring foreboding numbers counting down on a series of 7-segment displays. In this vein, [deshipu] developed a rather ridiculous take on the classic trope. The project is built around […]
Any exercise is a positive thing, but if you’re looking to improve over time, you’ve got to measure your performance. [Nikodem Bartnik] is a runner and is looking to improve his sprinting abilities. Naturally, an Arduino is the perfect companion to help in this quest (YouTube link, embedded below). The Arduino is built into a […]
How complicated can a toaster be? You can get a cheap one for way under $10 that is little more than a hot wire. However, there are a few little complications. First, consumer products need to be safe — lawsuits are expensive. Second, there has to be some mechanism to hold the toast down until […]
