Send & Receive Radio With A Single Chip

Fitting transmit and receive capabilities of radio signals into one device may be impossible without using a significant filter, which is needed to isolate sent and received signals from each other. The major obstacle to achieve that is the weakness of the received signal compared with the much stronger transmitted signal. However, researchers from Cornell University found their way to jump over this obstac ...

Arduino Projects: Audio VU Meter

Presented here is an Arduino based audio meter that uses a liquid crystal display (LCD). A VU meter or standard volume indicator (SVI) is a device that displays a representation of signal level in audio equipment. In this project, the intensity of left-channel and right-channel audio signals provided as input to Arduino UNO board is displayed as bars on the 16×2 LCD. In this circuit, analogue input pins of ...

THE SAMPLER THAT FITS IN YOUR POCKET

The future of the music instrument industry lies in synthesizers, and nowhere is this more apparent than the suite of tiny, pocket-sized synths more than capable of making bleeps and bloops. You’ve got tiny Korgs and Pocket Operators, and the time is ripe for people to wake up to tiny, pocket-sized synths. The latest in a wide, diverse range of pocketable synthesizers is the Bitty. It’s a pocket-sized drum ...

Arduino Parking Assistant

Those of us who have small garages know the frustration of parking a little bit too far in or a little too far out and not being able to walk around the vehicle. We recently bought a larger vehicle, and it has to be parked perfectly in the garage to walk around the front and back. To appease my frustration I decided to design a device that would allow me to park in the exact spot every time. I love working ...

IM282A-L – 10KM LONG RANGE RADIO MODULE FOR 2.4GHZ BAND

The only available radio chip for LoRa on the market has been the SX1272/76 from Semtech up to now. Things have changed and company IMST came up with the new type of radio chip SX1280 which can work on 2.4GHz band and decided to use this chip for their new LoRaWAN Long Range module, the iM282A-L. The iM282A-L is a compact and low-cost radio module that operates in the 2.4 GHz frequency band and combines the ...

TALKING WASHER IS A CLEAN SOLUTION FOR THE VISUALLY IMPAIRED

Have you shopped for an appliance lately? They’re all LEDs, LEDs everywhere. You might say that manufacturers are out of touch with the utility of tactile controls. [Wingletang]’s fancy new washing machine is cut from this modern cloth. While it does have a nice big knob for selecting cycles, the only indication of your selection is an LED. This isn’t an issue for [Wingletang], but it’s a showstopper for hi ...

Inside the vintage 74181 ALU chip

The 74181 ALU (arithmetic/logic unit) chip powered many of the minicomputers of the 1970s: it provided fast 4-bit arithmetic and logic functions, and could be combined to handle larger words, making it a key part of many CPUs. But if you look at the chip more closely, there are a few mysteries. It implements addition, subtraction, and the Boolean functions you'd expect, but why does it provide several bizar ...
