Richard of ARITH-MATIC had the idea to build a 4-bit computer based on 7400 series ICs (like the 74HC273, 74HC193, and 74HC125), but other responsibilities got in the way of this becoming a reality for quite some time. Finally, with the Retro Computer Festival at the Centre for Computing History in Cambridge, England held earlier […]
Do you need a small weight scale? You can of course buy one, or you could instead make your own 3D-printed device with a load cell and an Arduino, as shown in the below video by MN Maker. In his setup, the load cell first sends readings to an HX711 breakout board, which converts this […]
What really happens when you open the refrigerator door? Sure, you know intuitively that cold air escapes, but just how much? And how fast does the food inside actually heat up? To find out, Ryan Bates came up with his own data logging setup using an Arduino Uno, a custom sensor shield, and a microSD […]
As a kid you may have played Operation, but certainly never anything like this nine-foot-tall version from SPOT Technology. This device is not only impressively large, but assists doctors in their surgical pursuits with a CNC gantry setup to pull out obstructions. In the game, amateur surgeons control the system using a small arcade cabinet next […]
Spilled wine may be a hassle to clean up, but you might also observe that it makes interesting patterns. Marketing firm KPS3 had the same kind of thinking when they designed the web-controlled “Swirl Machine” to promote the Santa Maria Valley wine industry. The machine takes the form of a tabletop display, where a vacuum […]
You’ve seen barcode scanners register the price for your groceries, and likely in many other applications, but did you ever consider if one could be made into an instrument? Well we now know the answer, thanks to this MIDI guitar by James Bruton. Bruton’s amazing device presents a matrix of barcodes arranged on the instrument’s […]
Hearing live music is certainly enjoyable, but if the musician is using a drum machine, things can eventually get static. To add a bit more spontaneity into this class of robo-musician, Matt Bradshaw has created DrumKid — a handheld, battery-powered unit that uses random numbers to determine the rhythm and sound of a beat. The […]
Remembering to refill water and coffee cups at regular intervals certainly has to be a challenge for restaurant waitstaff, but not for servers at one diner thanks to Mark Wilson’s “TetrisWaterRun” project. Wilson’s device takes the form of a miniature arcade cabinet, with two “players” named H2O and JOE controlling Tetris playfields. As each block […]
Today we are releasing IDE 1.8.10 and you should try it because it’s awesome! With the support of our incredible community, we’ve been improving a lot of (small and not so small) things. Besides taking a look at the complete changelog, we’d like to point out one outstanding contribution that we received during this dev […]
The holidays are over and we’re back at work, so it’s time to clean up the house. To get ready for autumn, our amazing dev team has decided to devote an entire week to resolve as many of the open issues on the Arduino IDE repository and related projects (cores, libraries, etc.) as possible. Starting […]
