Musicians, makers and Arduino enthusiasts may be interested in a new project created by Max Danilin, showing a DIY automatic barrel piano, powered by an Arduino micro-controller and capable of outputing MIDI signals. A sheet is pulled under an array of 40 optocouplers using a hand crank and converted to sound using a MKR Zero […]

Step 1: Demonstration of Sensitivity On the video you can see the manufacturing process and the sensitivity of shocks Step 2: Components Otherwise, the seismometer itself consists of two parts, a mechanical tremor detector, and an electronic part that turns these tremors into electrical signals, amplified them and converts them into digital signals, which we

There’s no doubt that the RTL-SDR project has made radio hacking more accessible than ever, but there’s only so far you can go with a repurposed TV tuner. Obviously the biggest shortcoming is the fact that you can only listen to signals, and not transmit them. If you’re ready to reach out and touch someone,

Variable-speed playback cassette players were already the cool kids on the block. How else are you going to have any fun with magnetic tape without ripping out the tape head and running it manually over those silky brown strips? Sure, you can change the playback speed on most players as long as you can get

One of the most common clichés around here is that a piece of equipment chosen for a project is always too advanced. If a Raspberry Pi was used, someone will say they should have used an Arduino. If they use an Arduino, it should have been an ATtiny. And of course, if an ATtiny was

ePaper pricetags are becoming popular parts in the hacker community as a cheap way into tinkering with the technology. [Aaron Christophel] got his hands on a 4.4″ model with red, black, and white colors, and set about programming an ESP32 to drive the price tag instead. The protocol the display uses was reverse-engineered by prompting the

OMRON Corporation of Kyoto, western Japan globally released its new MOS FET (*1) relay module “G3VM-21MT” on December 2, 2019. The product is the first electronic component in the world (2) to adopt a “T-type circuit structure” (3). With a T-type circuit structure consisting of compact-size and longer-lifecycle solid-state relays that output signals using no physical contact, the relay
