Making a camera can be as easy as taking a cardboard box with a bit of film and a pin hole, but making a more accomplished camera requires some more work. A movie camera has all the engineering challenges as a regular camera with the added complication of a continuous film transport mechanism and shutter. […]
Texas Instruments is best known to the general public for building obsolete calculators and selling them at extraordinary prices to students, but they also build some interesting (and reasonably-priced) microcontrollers as well. While not as ubiquitous as Atmel and the Arduino platform, they can still be found in plenty of consumer electronics and reprogrammed, and
Despite great progress over the past century, more than a billion people still don’t have access to clean drinking water today. Much of the water on Earth’s surface is polluted, but it’s not always easy to tell a dirty stream from a clean one. Professional kit for water analysis can be expensive, which is why
MONITORING WATER QUALITY USING LOTS OF SENSORS AND MACHINE LEARNING Continue Reading

When you’re driving around, you might occasionally notice your indicators or windscreen wipers sync up fortuitously with the music. [Cranktown City] wanted to ensure his wipers would always match the beat, however, and set about making it so. After disassembling the wiper motor, The original controller PCB is ripped up, used solely for its home position contacts that
Flight yokes are key to getting an authentic experience when playing a flight simulator, but [Michel Rechtin] didn’t want to pay big money for a commercially-available solution. He ended up building a design using a lot of parts he had laying around, which saved money and worked out great. The build is based around an Arduino

Oscilloscopes were once commonly called CROs, for the fact that they relied on cathode ray tubes for display. Since then, technology has moved quickly, and oscilloscopes these days almost entirely rely on modern screens like LCDs. However, [lonesoulsurfer] went a different route with this fun DIY build, creating an oscilloscope with a low-resolution LED display. Yes,
Pinball machines are large, complex, and heavy boxes of joy and delight. However, when you don’t have the money or space for one, you have to make your own mini Raspberry Pi-powered one. With access to a local makerspace and a bit of extra free time, [Chris Dalke] had plans to capture the flavor of a
The Timex Datalink was arguably the first usable smartwatch, and was worn by NASA astronauts as well as geek icons like Bill Gates. It could store alarms, reminders and phone numbers, and of course tell the time across a few dozen time zones. One of the Datalink’s main innovations was its ability to download information

There are several projects you can imagine where it would be useful to have a robot follow you. For example, we’ve always wanted luggage that would trail us at the airport and we’ve seen several coolers that will follow you. [Madmax95] apparently dream of having a medical cart following a patient, though, and that’s good
