Arduino Cinque – The RISC-V, ESP32, WiFi, Bluetooth Arduino

This weekend at the Bay Area Maker Faire, Arduino in conjunction with SiFive, a fabless provider of the Open Source RISC-V micros, introduced the Arduino Cinque. This is a board running one of the fastest microcontrollers available, and as an added bonus, this board includes Espressif’s ESP32, another wonderchip that features WiFi and Bluetooth alongside a very, very powerful SoC.

Details on the Arduino Cinque are slim at the moment, but from what we’ve seen so far, the Cinque is an impressively powerful board featuring the RISC-V FE310 SoC from SiFive, an ESP32, and an STM32F103. The STM32 appears to …read more http://pje.fyi/PCj5r5

Pedometer for Calorie Conscious Hamster Owners

The Arduino has inspired many a creative projects that can be beneficial to humanity. The Arduino Hamster Wheel Pedometer by [John Mueller] on the other hand is a creation that is meant for the cute furry rodent pets. When [John Mueller]’s daughter wanted to keep track of her hamster’s night-time strolls, her maker-dad saw it as an opportunity to get her involved in technology. The project consists of a hamster-wheel with a magnet that triggers a reed switch on completing a revolution. The entire assembly is custom-made and [John Mueller] does an excellent job documenting the build with a lot …read more http://pje.fyi/PCd4Jp

Arduino (and Camera) Take Amazing Pictures

There’s an old joke where you ask someone what’s the most important thing about comedy. When they get to about the word “important,” you interrupt them and say, “Timing!” Perhaps the same thing can be said for photography. [Ted Kinsman’s] students at the Rochester Institute of Technology would probably agree. They built an Arduino-based rig to do inexpensive stop action photography.

As Arduino projects go, it isn’t very sophisticated. The circuit contains a  sound detection module and an optoisolator. The code would easily fit on a piece of notebook paper. When a loud sound occurs, the Arduino triggers the flash. …read more http://pje.fyi/PB4QWZ

Zen and the Art of Arduino

A zen garden should be a source of relaxation and escape from the everyday. The whole point should be to escape from–among other things–your electronics. Unless you are [MakrToolbox]. Then you’ll make a beautiful zen garden end table that allows you to make patterns in the sand using a ball bearing and an Arduino. You can see a video below.

Technically, the device is almost an upside down 3D printer with no Z axis. The mechanism moves a magnet which controls the steel ball and draws patterns in the sand. However, the really impressive parts of this project are the …read more http://pje.fyi/P9WTY9

Son of Sonoff

We’ve covered the Sonoff a few times–a very inexpensive box with an ESP8266, a power supply, and an AC relay along with a way to tap into a power cord. Very inexpensive means $5 or $6. The supplied software will work with several systems (including, recently, Alexa). But what self-respecting hacker wants to run the stock firmware on something with an ESP8266 inside?

[Tzapu] certainly didn’t. But he also knew he didn’t want to start from scratch every time he wanted to deploy a switch. So he built SonoffBoilerplate and put the code on GitHub. The code manages taking configuration …read more http://pje.fyi/P8WJNg

Translate Color to Smell with Bouquet

Hope springs eternal for Smell-O-Vision. [Niklas Roy] recently taught a workshop called Communication Devices at ÉCAL in Lausanne, Switzerland. Four of his Media & Interaction Design students built a scanner that detects colors and emits a corresponding scent.

The project consists of an Arduino connected to a color sensor as well as a SparkFun EasyDriver. The EasyDriver controls a stepper motor which rotates a disc of scent swatches so you sniff the swatch corresponding with the color. The students chose strawberry for red, and blue ended up being “ocean”-scented room spray.

With design students involved it’s no surprise the project  …read more http://pje.fyi/P7r9QY

DIY Lap Counters for Drone Racing

Drone racing is a very exciting sport, in which there is a lot of room for hackers and makers to add that special sauce into the mix. Usually the aerial finish line requires special race-timing hardware to do the lap counting, and there are timing gate transponders available for around $40. In his project CoreIR and CoreIR-Uplink, [Michael Rickert] decided to reverse engineer the IR Protocol that goes into these beacons and made a homebrew version that mimics the original. The transponders send a 7-digit number out repeatedly to a receiver at the finish line as the UAV passes by  …read more http://pje.fyi/P5Wggh
