When [Stephen Cass] found himself with a broken Tandy TRS-80 Model 100 portable computer, the simplest solution was to buy another broken one and make one working computer from two non-working computers. However, this left him with a dilemma — what to do with the (now even more) broken one left over? Naturally, he did […]

Pi-files: Doorbell alert with pushmessage and mail with webcam footage Actually the first ‘project’ I ever did with a Raspberry Pi was sending a push message to my Iphone. It was 2012, I was lying sick in bed and found a new app on my Iphone called Pushover (what else to do when you’re sick?).

Infineon Technologies AG has collaborated with software and 3D Time-of-Flight (ToF) system specialist pmdtechnologies ag to develop reportedly the world’s smallest, most powerful 3D image sensor. Designated the REAL3, the single-chip solution measures just 4.4 x 5.1 mm and is the fifth generation of time-of-flight deep sensors from Infineon. The sensor can be incorporated into even the smallest devices with just

This time I’m starting off with a device I already built, unfortunately there won’t be any photos from the actual build, just a quick article on how I imagined it and how it works. A short story about how the whole thing started My uncle has a nice little place at the countryside at about
If there’s one thing we’ve learned over the years, it’s that if it’s got a silicon chip inside, it could be carrying a virus. Research by one group focused on hiding a trojan inside an AVR Arduino bootloader, proving even our little hobbyist microcontrollers aren’t safe. The specific aim of the research was to hide a
[Noteolvides] creates the CubeTouch, a cube made of six PCBs soldered together that creates a functional and interactive piece of art through its inlaid LEDs and capacitive touch sensors. The device itself is connected through a USB-C connector that powers the device and allows it to send custom keyboard shortcuts, depending on which face is touched.

Arduinos have been the microcontroller platform of choice for nearly two decades now, essentially abstracting away a lot of the setup and lower-level functions of small microcontrollers in favor of sensible IDEs and ease-of-use. This has opened up affordable microcontrollers to people who might not be willing to spend hours or days buried in datasheets,
