If you grew up watching Honey I Shrunk the Kids, you may recall the scene with Wayne Szalinski’s remote-controlled lawn mower. Inspired by the 1989 film, “elliotmade” designed a version of his own a few years ago that’s still functioning today. With a successful proof of concept, he decided to assemble a second version featuring some improvements like an FPV camera; however, this one was for Elliot’s wheelchair-using friend to help him retain his independence. The mower is driven by a pair of power wheelchair/scooter wheels and motors via differential steering. It uses an RC-style setup for primary control, along with an Arduino Nano that activates a couple relays for an electric starter setup, as well as a cutoff and battery switch. Once the mower’s combustion engine is started, it then replenishes the battery through an alternator, allowing it to keep going until gas runs out. 📷 instructables.com/member/elliotmade

Measuring voltage with a multimeter is easy enough, and current is a bit harder, but reading both values simultaneously can be a challenge. If you’re tired of having to replug or find two meters, then look no further than Karl Kristian Torp’s palm-sized Tiny V/A. His Nano-based unit takes input from a power supply via a female barrel jack connector. This supplies the load through a male connector output, and also powers the Arduino, an IN219 sensor, and a 0.96” OLED display. Everything is housed inside a 3D-printed case. A single capacitive touch button allows you to easily navigate Tiny V/A’s menu and change settings. Additionally, it can be powered over USB as needed for an expanded voltage range. 📷 instructables.com/member/KarlTorp

When wearing a face mask nowadays, you can’t show expressions in the same ways that we’re all accustomed to. As a possible solution to this problem, Tyler Glaiel decided to create a custom covering with an 8×8 LED matrix that picks up his voice and imitates his mouth moving. It even allows him to smile by sensing when he makes a “pop” sound. The build is entirely self-contained, with a Nano, 9V power supply, and electret mic embedded in the mask’s translucent black cloth. 😷 medium.com/@tglaie 📹 twitter.com/TylerGlaiel

After breaking their Wahoo bike computer, cubicpixelDE decided to create their own using a Nano 33 BLE Sense, BLE heart rate sensor, RPM speed and cadence sensor, 240 x 240 IPS TFT display, and GPS module. 📷 youtube.com/cubicpixelDE

If you want a virtual reality headset for your computer, but don’t want to dig deep into your pockets, this project by “jamesvdberg” presents a low-cost alternative. Although it won’t pack the capabilities of an Oculus or HTC Vive, the VR rig can be replicated for just $80 using a Google cardboard-compatible shell, along with a 5” Raspberry Pi 800×480 LCD screen and an Arduino Micro for control. The DIY device tracks head movements using an MPU6050 IMU, sending data to a PC system as a mouse input via the Micro. Game visuals are fed back to the screen over HDMI, split into discreet images for each eye, creating a side-by-side 3D effect. 📷 instructables.com/member/jamesvdberg

The Internet has been perhaps more important than ever to keep us connected these days. Available technology, however, apparently wasn’t good enough for brothers Hunter and Josh Irving, who built their own telepresence robot using parts on-hand during their own two-person hackathon. The robot they came up with, dubbed TELEBOT, features a partially 3D-printed face along with a set of chattering teeth and eyes recycled from an antique doll. An Arduino Uno is used to take audio signals from remote “guests” via a standard 3.5mm cable, simulating their facial expressions with servos that drive TELEBOT’s mouth and LED-lit eyes. The duo also made TELEBOT’s “body” out of an adjustable lamp for manual movement. And, as an added bonus, the device is capable of glowing in the dark and can be customized with a wizard, cowboy or top hat. 📷 hunterirving.com

Turn a vintage rotary phone dial into a volume control for your Windows PC! This device plugs into your computer through USB, and will automatically set every open program's volume to whatever number you dial. For example, if you dial a "2, " the volume will be set to 20%. Dial an "8" and it will be set to 80%. Dialing "0" sets it to 0% and acts like mute. ☎️ create.arduino.cc/projecthub/cameroncoward

"What's for dinner? FR4 with a side of solder and flux gravy, sprinkled with 0603s!" @element14community member 'wolfgangfriedrich' designed a pair of hot plates around the Nano Every — a bare MCH element that only fits very small boards (20mm x 60mm) and an aluminum plate with two MCH elements mounted in series for more power and a larger heated area (70mm x 120mm) to solder bigger boards. 📷 element14.com/community/people/wolfgangfriedrich

This palm-sized 4WD robot, which consists of a MKR WiFi 1010 coupled with a MKR Motor Carrier and four N20 motors, can be controlled over Bluetooth using either the Nano 33 BLE Sense's IMU or an Android application. 📷 create.arduino.cc/projecthub/Avilmaru

How do we know that planets exist outside of our solar system? While too far away to observe directly, with extremely sensitive equipment like the Kepler space telescope it’s possible to detect changes in light as these exoplanets pass in front of a star. For an excellent visualization of how this all works, check out Marcin Poblock’s simplified model! The 3D-printed apparatus employs an Arduino Nano that controls the motion of two planets around a light bulb “star,” via a stepper motor and gear system. The variable light is then sensed by an LDR on a separate Nano-driven device. This sends info to a computer over serial to be graphed in real-time, and can also store it on an SD card for later analysis. While this project won’t necessarily help you explore our galaxy, it will provide you with a fun way to learn about the principle of exoplanet detection using the transit method. 🌑 instructables.com/member/poblocki1982
