To label used bottles that would otherwise go to waste, “tuenhidiy” created a CNC plotter that itself consists mostly of scraps! The machine’s X and Z axes are formed out of a pair of old CD/DVD players, but instead of a traditional Y axis, it actuates two printer rollers to turn a bottle forwards or […]
You’ve probably seen an example of the “useless box,” or “useless machine,” which when switched on does nothing except open up to turn itself back off again. This one by creator Alex Pikkert adds a few new tricks, giving it a bit of a mood, and not one but two switches and fingers! When switched […]
We are happy to announce a new partnership with Lauterbach to provide all Portenta H7 customers with the TRACE32 debugger for free. Lauterbach’s TRACE32 debugger has been at the forefront of debug technology for more than four decades, and it is this wealth of experience and expertise that Lauterbach will draw on for the Arduino Portenta. […]
After making an indoor Executive Par 3 golf game with a ramp and cups like a skee-ball machine, creator “gcal1979” decided to add an automatic scoring system to the rig. What he came up with uses infrared break beam sensors for each of the three holes, feeding info to an Arduino Mega. Stats are shown […]
When creator mattb_138’s parents were cleaning out their house, he came across an old cassette player and decided to upgrade it with MP3 capabilities and an RFID interface. The newly-enhanced device uses an Arduino Nano for control, along with a DFPlayer Mini module to play songs stored on a microSD card. An RC522 reader enables […]
Ground penetrating radar systems, which can be used to sense the density of objects under the Earth, are normally seen as a fairly exotic piece of equipment. Naturally, such devices cost thousands of dollars. Mirel Paun’s “GPRino” prototype, though, aims to accomplish this viewing task for the comparatively paltry sum of $300. The GPRino uses antipodal […]
Earlier this year we covered an automated perpetual calendar, which used three ring gears to align the date, month, and day of the week with a viewing window. After building one of these devices, Wolfspaw was inspired to put a new “spin” on things by combining it with a linear Cryptic Calendar, featuring digits that […]
What if you could print circuit “tattoos” right on your body? While the idea of augmentation with a pre-assembled electronic sticker isn’t new, the technique proposed by a team of KAIST and MIT Media Lab researchers takes things to a new level. Their small BodyPrinter device — composed of a custom 3D-printed plotter with a […]
Can you make an Arduino-controlled neon sign? While certainly possible, such a setup would involve working with rather high voltages, and the skill to shape glass tubing. As an easier alternative, Max Danilin (who also goes by “gabbapeople”) created an animated pub display using lengths of LED strips made to look like old-school neon tubes. Although such […]
While you may or may not have frozen ponds where you live, if you have an available smooth surface you can still enjoy a game of floor hockey with this brilliantly illuminated puck. Yuksel Temiz’s 3D-printed device features a 12-LED ring inside, which shines brightly through the top of its translucent body and reacts to […]
